Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995 
Readers should note that in addition to the historical information contained herein, some of the information in this 
report  contains  forward-looking  statements  within  the  meaning  of  the  federal  securities  laws.    Forward-looking 
statements  typically  are  identified  with  use  of  terms  such  as  “may,”  “will,”  “expect,”  “anticipate,”  “estimate,” 
“potential,” “could”: and similar words, although some forward-looking statements are expressed differently.  You 
should  be  aware  that  the  Company’s  actual  results  could  differ  materially  from  those  contained  in  the  forward-
looking statements due to a number of factors, including: burdens imposed by federal and state regulation, changes 
in  accounting  regulation  or  standards  of  banks;  credit  risk;  exposure  to  general  and  local  economic  conditions; 
risks  associated  with  rapid  increase  or  decrease  in  prevailing  interest  rates;  consolidation  within  the  banking 
industry;  competition  from  banks  and  other  financial  institutions;  our  ability  to  attract  and  retain  relationship 
officers and other key personnel and technological developments; all of which could cause the Company’s actual 
results to differ from those set forth in the forward-looking statements.  

Other  factors  that  could  cause  results  to  differ  from  expected  results  include  the  acquisition  of  Millennium,  the 
integration of our recent acquisition of NorthStar and our recent acquisition of Clayco, all of which could result in 
costs  and  expenses  that  are  greater,  or  benefits  that  are  less,  than  we  currently  anticipate,  or  the  assumption  of 
unanticipated liabilities. 

Readers are cautioned not to place undue reliance on our forward-looking statements, which reflect management’s 
analysis only as of the date of the statements.  The Company does not intend to publicly revise or update forward-
looking  statements  to  reflect  events  or  circumstances  that  arise  after  the  date  of  this  report.    Readers  should 
carefully review all disclosures we file from time to time with the Securities and Exchange Commission which are 
available on our website at www.enterprisebank.com. 

PART I 

ITEM 1: BUSINESS 

General 
Enterprise  Financial  Services  Corp  (“EFSC”  or  “the  Company”),  a  Delaware  corporation,  is  a  financial  holding 
company headquartered in St. Louis, Missouri.  At December 31, 2006, our wholly owned subsidiary, Enterprise 
Bank  &  Trust  (“Enterprise”  or  “the  Bank”),  a  Missouri  chartered  trust  company  with  banking  powers,  was  the 
largest publicly held bank, in asset size, headquartered in St. Louis, Missouri, with $1.5 billion in assets.  Enterprise 
is a regional bank primarily serving the St. Louis and Kansas City metropolitan areas.  

The Company’s stated mission is “to guide our clients to a lifetime of financial success.”  We have established an 
accompanying corporate vision “to build an exceptional company that clients value, shareholders prize and where 
our associates flourish.”   These tenets are fundamental to the Company’s business strategies and operations. 

Enterprise  is  highly  focused  on  serving  the  needs  of  private  businesses,  their  owner  families  and  other 
professionals.    This  is  achieved  through  two  primary  lines  of  business:  commercial  banking  and  wealth 
management.  We offer full product lines in each line of business.   

The commercial banking line of business offers a broad range of business and personal banking services.  Lending 
services include commercial, commercial real estate, financial and industrial development, real estate construction 
and development, residential real estate, and consumer loans.  A wide variety of deposit products and a complete 
suite of treasury management services complement our lending capabilities. 

The wealth management line of business provides fee-based corporate and personal financial consulting, advisory 
and trust services to our target markets.  Corporate consulting services are focused in the areas of retirement plans, 
management  compensation  and  management  succession  planning.    Personal  financial  consulting  includes  estate 
planning, investment management and retirement planning. In 2005, we acquired controlling interest in Millennium 
Brokerage  Group,  LLC  (“Millennium”),  a  life  insurance  advisory  and  brokerage  operation  serving  life  agents, 
banks,  CPA  firms,  property  and  casualty  groups  and  financial  advisors.    Millennium’s  capabilities,  market  reach 
and industry presence have significantly enhanced our wealth management business line and opened new wholesale 
marketing opportunities for the Company while expanding our fee income sources. 

Our executive offices are located at 150 North Meramec, Clayton, MO 63105 and our telephone number is (314) 
725-5500.

Available Information  
The  Company’s  Internet  website  is  www.enterprisebank.com.    Various  reports  provided  to  the  Securities  and 
Exchange  Commission  (“SEC”),  including  our  annual  reports,  quarterly  reports,  current  reports  and  proxy 
statements  are  available  free  of  charge  on  our  website.    These  reports  are  made  available  as  soon  as  reasonably 
practicable after they are filed with or furnished to the SEC.   

2006 Acquisitions  
On  July  5,  2006,  the  Company  completed  the  acquisition  of  NorthStar  Bancshares,  Inc.  and  its  wholly  owned 
subsidiary, NorthStar Bank N.A. (“NorthStar”), a $187.5 million banking company in Kansas City, MO, for $36.0 
million in EFSC stock and cash.  NorthStar Bancshares, Inc. was merged into Enterprise Financial Services Corp 
on  the  acquisition  date.    In  October  2006,  we  successfully  integrated  NorthStar’s  systems  and  accounts  into 
Enterprise Bank & Trust’s and converted four of five NorthStar branches to Enterprise branches.  One NorthStar 
branch was closed. 

As a result of the NorthStar acquisition, at December 31, 2006 the Bank’s assets in the Kansas City market grew to 
approximately $400.0 million, operating from six branches. 

On  November  22,  2006,  the  Company  entered  into  a  definitive  agreement  to  acquire  Kansas  City-based  Clayco 
Banc  Corporation  (“Clayco”)  for  $37.0  million  in  EFSC  stock  and  cash.    Clayco  is  the  parent  company  of  the 
$201.9 million Great American Bank (“Great American”) with branches in DeSoto, KS and Claycomo, MO.  The 
transaction closed on February 28, 2007.  We do not expect to integrate Great American into Enterprise Bank & 
Trust until early 2008. 

With the acquisition of Clayco, assets in the Kansas City market will total approximately $600.0 million – roughly 
a threefold increase since year-end 2005. 

See Note 2 – Acquisitions and Note 4 - Subsequent Events in this filing for more information.   

Business Strategy 
Our  general  business  strategy  is  to  generate  superior  shareholder  returns  by  concentrating  on  private  businesses, 
their owner families and other success-minded individuals and providing comprehensive financial services through 
banking and wealth management lines of business.  

Key  success  factors  in  pursuing  this  strategy  include  a  focused  and  relationship-oriented  distribution  and  sales 
approach, emphasis on growing wealth management revenues, aggressive credit and interest rate risk management, 
advanced technology and tightly managed expense growth.   

Building long-term client relationships – The Bank’s historical growth strategy has been client relationship driven.  
The Bank continuously seeks to add clients who fit our target market of business owners and associated families.  
Those relationships are maintained, cultivated and expanded over time.  This strategy enables the Bank to attract 
clients with significant and growing borrowing needs, in tandem with the Bank’s increasing capacity to fund client 
loan requests.  The Bank’s officers are typically highly experienced and trained to establish and develop long-term 
relationships.  As a result of its long-term relationship orientation, the Bank is able to fund loan growth primarily 
with core deposits from its business and professional clients.  This is supplemented by borrowing from the Federal 
Home Loan Bank, and by issuing brokered certificates of deposits, priced at or below the Bank’s alternative cost of 
funds.   

Growing  Trust  business  –  Enterprise  Trust,  a  division  of  the  Bank,  has  grown  to  $1.6  billion  in  assets  under 
administration in eight years by offering fiduciary and financial advisory services.  We employ a full complement 
of  attorneys,  certified  financial  planners,  estate  planning  professionals,  as  well  as  other  investment  professionals 
who offer a broad range of services for business owners and high net worth individuals.  Employing an intensive, 
personalized  methodology,  Enterprise  Trust  representatives  assist  clients  in  defining  lifetime  goals and designing 
plans  to  achieve  them.  Consistent  with  the  Company’s  long-term  relationship  strategy,  Trust  representatives 
maintain  close  contact  with  clients  ensuring  follow  up,  discipline,  and  appropriate  adjustments  as  circumstances 
change.    The  results  have  been  excellent,  as  measured  by  client  satisfaction,  rapid  growth,  and  contributions  to 
Company earnings. 

Wholesale  distribution  opportunities  –  Historically,  we  have  distributed  products  and  services  directly  to  clients 
through local offices of the Bank.  However, the application of newer technologies to the delivery of bank and trust 
products, coupled with the increasing trend toward consolidation of financial services, has created an opportunity 
for the Company to pursue a wholesale distribution strategy to complement our direct operations.  In a wholesale 

2

 
 
 
 
 
 
 
 
 
 
 
arrangement,  Enterprise  distributes  products  and  services  indirectly  to  clients  through  an  intermediary,  such  as 
another bank, financial services firm or financial advisor.     

Our  acquisition  of  Millennium  is  one  example  of  how  we  are  executing  our  wholesale  strategy.    Millennium 
provides  life  insurance  products  and  related  consulting  services  to  other  independent  life  insurance  agents,  CPA 
firms, banks, property & casualty insurance agents and financial advisors.   

As another component of this wholesale strategy, the Company has applied to the Office of Thrift Supervision for a 
federal savings bank charter with trust-only authority.  This charter, if approved, will allow the Company to offer 
its trust advisory and fiduciary services, through both direct and wholesale distribution, on a nationwide basis. 

The Bank also offers selected deposit products through several existing wholesale distribution arrangements. 

Capitalizing on technology – We view our technological capabilities to be a competitive advantage.  Our systems 
provide Internet banking, expanded treasury management products, checks and document imaging, as well as a 24-
hour  voice  response  system.    Other  services  currently  offered  by  the  Bank  include  controlled  disbursements, 
repurchase  agreements  and  sweep  investment  accounts.    Our  treasury  management  suite  of  products  blends 
advanced technology and personal service, often creating a competitive advantage over larger, nationwide banks. 
Technology  is  also  utilized  extensively  in  internal  systems,  operational  support  functions  to  improve  customer 
service, and management reporting and analysis. 

Maintaining  asset  quality  –  Senior  Management  and  the  head  of  Credit  administration  monitor  our  asset  quality 
through regular reviews of loans.  In addition, the loan portfolio is subject to ongoing monitoring by a loan review 
function that reports directly to the audit committee of our board of directors.  

The  Bank’s  investment  policy  is  designed  to  enhance  its  net  income  and  return  on  equity  through:  prudent 
management  of  risk;  ensuring  liquidity  to  meet  cash-flow  requirements;  managing  interest  rate  risk;  ensuring 
availability of collateral for public deposits, advances and repurchase agreements; and to seek asset diversification.  
Through  our  Asset/Liability  Management  Committee  (“ALCO”),  Bank  liquidity  is  managed  by  structuring  the 
maturity  dates  of  investments  to  maintain  an  appropriate  relationship  between  assets  and  liabilities  while 
maximizing  interest  rate  spreads.    Accordingly,  the  ALCO  monitors  the  sensitivity  of  assets  and  liabilities  with 
respect to changes in interest rates and maturities and directs the overall acquisition and allocation of funds.  ALCO 
also utilizes derivative financial instruments to assist in the management of interest rate sensitivity by modifying 
the re-pricing, maturity and option characteristics of certain assets and liabilities.   

Expense  management  –  The  Company  is  focused  on  leveraging  its  current  expense  base  and  measures  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).  Continued improvement is targeted to maintain strong 
earnings per share growth and generate higher returns on equity. 

Market Areas and Approach to Geographic Expansion 
The Bank has four banking facilities in St. Louis metropolitan area.  The St. Louis region enjoys a stable, diverse 
economic base and is ranked the 18th largest MSA in the United States.  It is an attractive market for us with nearly 
60,000  privately  held  businesses  and  over  80,000  households  with  investible  assets  of  $1.0  million  or  more.  As 
noted previously, we are the largest publicly-held, locally headquartered bank in this market.  

In  2006  the  Company  substantially  strengthened  its  market  position  in  Kansas  City.    Kansas  City  is  also  a  rich 
private  company  market  with  over  48,000  businesses  and  over  54,000  households  with  investible  assets  of  $1.0 
million  or  more.    As  mentioned  previously,  the  Company  almost  doubled  its  size  in  Kansas  City  in  2006.  The 
planned acquisition of Clayco Banc Corporation will increase the Company’s assets in the Kansas City market to 
roughly $600.0 million on a pro-forma basis, making Enterprise one of the fastest growing banks in the Kansas City 
market.  

The  Company,  as  part  of  its  expansion  effort,  plans  to  continue  its  strategy  of  operating  relatively  fewer  offices 
with  a  larger  asset  base  per  office,  emphasizing  commercial  banking  and  wealth  management  and  employing 
experienced staff who are compensated on the basis of performance and customer service.    

By virtue of its Millennium subsidiary and other wholesale distribution operations, subject to applicable regulatory 
restrictions, the Company provides services beyond St. Louis and Kansas City in markets across the United States.

Competition 
The Company and its subsidiaries operate in highly competitive markets.  Our geographic markets are served by a 
number of large multi-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.  
Also, both the St. Louis and Kansas City markets are experiencing an increase in de novo banks, which have either 
opened or are in the application stage.  In addition to other financial holding companies and commercial banks, we 
compete  with  credit  unions,  investment  managers,  brokerage  firms,  and  other  providers  of  financial  services  and 
products.   

Supervision and Regulation 
The  Company  and  the  Bank  are  subject  to  state  and  federal  banking  laws  and regulations which impose specific 
requirements or restrictions on and provide for general regulatory oversight with respect to virtually all aspects of 
operations.  These laws and regulations are intended to protect depositors, and shareholders to some extent.  To the 
extent  that  the  following  summary  describes  statutory  or  regulatory  provisions,  it  is  qualified  in  its  entirety  by 
reference to the particular statutory and regulatory provisions.  Any change in applicable laws or regulations may 
have  a  material  effect  on  the  business  and  prospects  of  the  Company.    The  numerous  regulations  and  policies 
promulgated by the regulatory authorities create a difficult and ever-changing atmosphere in which to operate.  The 
Company  and  the  Bank  commit  substantial  resources  in  order  to  comply  with  these  statutes,  regulations  and 
policies.  The Company is unable to predict the nature or the extent of the effect on its business and earnings that 
fiscal or monetary policies, economic control, or new federal or state legislation may have in the future. 

Millennium and the investment management industry in general are subject to extensive regulation in the United 
States  at  both  the  federal  and  state  level,  as  well  as  by  self-regulatory  organizations  such  as  the  National 
Association of Securities Dealers, Inc. ("NASD").  The Securities and Exchange Commission is the federal agency 
that  is  primarily responsible for the regulation of investment advisers.   Millennium is licensed to sell insurance, 
including variable insurance policies, in various states and is subject to regulation by the NASD.  This regulation 
includes supervisory and organizational procedures intended to assure compliance with securities laws, including 
qualification  and  licensing  of  supervisory  and  sales  personnel  and  rules  designed  to  promote  high  standards  of 
commercial integrity and fair and equitable principles of trade.  

The 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 Board, and is required to file periodic reports of its operations and such additional information 
as the Federal Reserve 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 have at least a “satisfactory” rating 
under the Community Reinvestment Act.  See “Capital Resources” in the Management Discussion and Analysis for 
more information on our capital adequacy and “Enterprise Bank – Community Reinvestment Act” below for more 
information on Community Reinvestment.     

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.  Federal 
legislation permits bank holding companies to acquire control of banks throughout the United States. 

Permissible Activities: The Gramm-Leach-Bliley Act of 1999 (“GLBA”) eliminates many of the restrictions placed 
on  the  activities  of  certain  qualified  financial  or  bank  holding  companies.    A  financial  holding  company  such  as 
EFSC  can  expand  into  wide  variety  of  financial  services,  including  securities  activities,  insurance  and  merchant 
banking without the prior approval of the Federal Reserve.   

Privacy  Regulation:  GLBA  also  imposes  restrictions  on  the  Company  and  the  Bank  regarding  the  sharing  of 
customer  non-public  personal  information  with  non-affiliated  third  parties  unless  the  customer  has  had  an 
opportunity  to  opt  out  of  the  disclosure.    GLBA  also  imposes  periodic  disclosure  requirements  concerning  the 
Company and the Bank policies and practices regarding data sharing with affiliated and non-affiliated parties. 

Source  of  Strength;  Cross-Guarantee.    In  accordance  with  Federal  Reserve  policy,  we  are  expected  to  act  as  a 
source of financial strength to the Bank and to commit resources to support the Bank.  The Federal Reserve takes 
the  position  that  in  implementing  this  policy,  it  may  require  us  to  provide  financial  support  when  we  otherwise 
would not consider ourselves able to do so.

Sarbanes-Oxley Act.  On July 30, 2002, President Bush signed into law the Sarbanes-Oxley Act of 2002 (“SOX”).  
The stated goals of SOX are to increase corporate responsibility, to provide for enhanced penalties for accounting 
and  auditing  improprieties  at  publicly  traded  companies  and  to  protect  investors  by  improving  the  accuracy  and 
reliability  of  corporate  disclosures  made  pursuant  to  the  securities  laws.    The  changes  are  intended  to  allow 
shareholders to monitor the performance of companies and directors more easily and efficiently. 

SOX  generally  applies  to  all  companies,  both  U.S.  and  non-U.S.,  that  file  or  are  required  to  file periodic reports 
with the SEC under the Securities Exchange Act of 1934 and includes specific additional disclosure requirements 
and  new  corporate  governance  rules.    The  Act  addresses,  among  other  matters,  (i)  certification  of  financial 
statements  by  the  chief  executive  officer  and  the  chief  financial  officer,  (ii)  management  assessment  of  internal 
controls with the issuer’s auditor attesting to and reporting on such assessment, (iii) the forfeiture of certain bonuses 
in  the  event  of  a  restatement  of  financial  results.    In  addition,  public  companies  whose  securities  are  listed  on  a 
national securities exchange must satisfy the following additional requirements: (i) the company’s audit committee 
must  appoint  and  oversee  the  company’s  auditors,  (ii)  each  member  of  the  company’s  audit  committee  must  be 
independent,  (iii)  the  company’s  audit  committee  must  establish  procedures  for  receiving  complaints  regarding 
accounting, internal accounting controls and audit-related matters, (iv) the company’s audit committee must have 
the  authority  to  engage  independent  advisors  and  (v)  the  company  must  provide  appropriate  funding  to  its  audit 
committee, as determined by the audit committee. 

Enterprise Bank & Trust 
The Bank is a Missouri trust company with banking powers.  It is not a member of the Federal Reserve System.  
The Missouri Division of Finance and the Federal Deposit Insurance Corporation (“FDIC”) are primary regulators 
for the Bank.  These regulatory authorities regulate or monitor all areas of the Bank’s 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, and furniture and 
fixtures. 

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.   

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 Company has a satisfactory 
rating under CRA. 

USA Patriot Act: On October 26, 2001, President Bush signed into law the Uniting and Strengthening America by 
Providing  Appropriate  Tools  Required  to  Intercept  and  Obstruct  Terrorism  Act  of  2001  (the  "USA  PATRIOT 
Act").  Among its other provisions, 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. 

Check 21:  The Check Clearing for the 21st Century Act (“Check 21”) was signed into law on October 28, 2003, 
and became effective on October 28, 2004. Check 21 is designed to foster innovation in the payments system and to 
enhance  its  efficiency  by  reducing  some  of  the  legal  impediments  to  check  clearing.    The  law  facilitates  check 
clearing  by  creating  a  new  negotiable  instrument  called  a substitute  check,  which permits banks to clear original 
checks, to process check information electronically, and to deliver substitute checks to banks that want to continue 

5

 
 
 
 
 
 
 
receiving  paper  checks.    A  substitute  check  is  the  legal  equivalent  of  the  original  check  and  includes  all  the 
information contained on the original check. The law does not require banks to accept checks in electronic form nor 
does it require banks to use the new authority granted by Check 21 to create substitute checks. 

Limitations  on  Loans  and  Transaction:    The  Federal  Reserve  Act  generally  imposes  certain  limitations  on 
extensions of credit and other transactions by and between banks that are members of the Federal Reserve and other 
affiliates (which includes any holding company of which a bank is a subsidiary and any other non-bank subsidiary 
of such holding company).  Banks that are not members of the Federal Reserve are also subject to these limitations.  
Further,  federal  law  prohibits  a  bank  holding  company  and  its  subsidiaries  from  engaging  in  certain  tie-in 
arrangements in connection with any extension of credit, lease or sale of property or the furnishing of services. 

Other Regulations:  Interest and certain other charges collected or contracted for by the Bank are subject to state 
usury laws and certain federal laws concerning interest rates.  The Bank’s loan operations are also subject to certain 
federal  laws  applicable  to  credit  transactions,  such  as  the  federal  Truth-In-Lending  Act  governing  disclosures  of 
credit terms to consumer borrowers; the Home Mortgage Disclosure Act of 1975 requiring financial institutions to 
provide information to enable the public and public officials to determine whether a financial institution is fulfilling 
its  obligation  to  help  meet  the  housing  needs  of  the  community  it  serves;  the  Equal  Credit  Opportunity  Act 
prohibiting discrimination on the basis of race, creed or other prohibited factors in extending credit; the Fair Credit 
Reporting  Act  of  1978  governing  these  and  provision  of  information  to  credit  reporting  agencies;  the  Fair  Debt 
Collection  Act  governing  the  manner  in  which  consumer  debts  may  be  collected  by  collection  agencies;  the 
Soldiers’ and Sailors Civil Relief Act of 1940, governing the repayment terms of, and property rights underlying 
obligations of persons in military service; and the rules and regulations of the various federal agencies charged with 
the  responsibility  of  implementing  such  federal  laws.  The  deposit  operations  of  the  Bank  are  also  subject  to  the 
Right to Financial Privacy Act, which imposes a duty to maintain confidentiality of consumer financial records and 
prescribes procedures for complying with administrative subpoenas of financial records, and the Electronic Funds 
Transfer Act and Regulation E issued by the Federal Reserve Board to implement that act, which governs automatic 
deposits  to  and  withdrawals  from  deposit  accounts  and  customers’  rights  and  liabilities  arising  from  the  use  of 
automated teller machines and other electronic banking services. 

Deposit Insurance:  The deposits of the Bank are currently insured by the FDIC to a maximum of $100,000 per 
depositor,  subject  to  certain  aggregation  rules.    The  FDIC  establishes  rates  for  the  payment  of  premiums  by 
federally  insured  banks  for  deposit  insurance.    An  insurance  fund  is  maintained  for  commercial  banks,  with 
insurance premiums from the industry used to offset losses from insurance payouts when banks and thrifts fail.  The 
FDIC has adopted a risk-based deposit insurance premium system for all insured depository institutions, including 
the Bank, which requires premiums from a depository institution based upon its capital levels and risk profile, as 
determined by its primary federal regulator on a semiannual basis. 

ITEM 1A: RISK FACTORS 

At any given time, the Company is subject to any number of risk factors that may affect the market price of the 
Company’s stock.  Some of the specific risks include the following: 

The Bank’s allowance for loan losses may be inadequate, which could impair our earnings.  The Bank’s allowance 
for loan losses may not be adequate to cover actual loan losses and if the Bank is required to increase its reserve, 
current earnings will be reduced. Our experience shows that some borrowers either will not pay on time or will not 
pay at all, which will require the Bank to charge-off the defaulted loan or loans. We provide for losses by reserving 
what we believe to be an adequate amount to absorb any probable inherent losses. A charge-off reduces the Bank’s 
allowance  for  loan  losses.  If  the  Bank’s  reserves  were  insufficient,  it  would  be  required  to  increase  reserves  by 
recording a larger provision for loan losses, which would reduce earnings for that period.  

Changes  in  economic  conditions  could  cause  an  increase  in  delinquencies  and  non-performing  assets,  including 
loan charge-offs, which in turn may negatively affect the Company’s income and growth. Demand for loans may 
decrease during economic downturns as a result of, among other things, an increase in unemployment, a decrease in 
real  estate  values  or  increases  in  interest  rates.  These  factors  could  depress  our  earnings  and  consequently  our 
financial condition because:  

customers may not want or need the Company’s products and services; 

• 
•  borrowers may not be able to repay their loans; 
• 
• 

the value of the collateral securing the Bank’s loans to borrowers may decline; and  
the quality of the Bank’s loan portfolio may decline.  

6

 
 
 
 
 
 
 
  
  
  
Any of these scenarios could cause an increase in delinquencies and non-performing assets or require us to charge-
off a percentage of loans and/or increase the provisions for loan losses, which would reduce our earnings.  

A prolonged flat or inverted yield curve may reduce our net income and cash flows.  The interest rate yield curve is 
normally  upward  sloping  where  absolute  interest  rates  are  higher  as  the  maturity  of  the  financial  instrument 
lengthens.    During  2006,  the  curve  became  inverted  where  rates  were  lower  on  longer-term  maturities.    If  this 
condition persists throughout 2007, we will likely experience continued compression of our interest rate spread and 
related net interest rate margin, which would have a negative impact on our profitability. 

Because the Bank competes primarily on the basis of the interest rates it offers depositors and the terms of loans it 
offers borrowers, the Bank’s margins could decrease if it were required to increase deposit rates or lower interest 
rates on loans in response to competitive pressure.  The Bank faces intense competition both in making loans and 
attracting deposits. It competes primarily on the basis of its depository rates, the terms of the loans it originates and 
the  quality  of  its  financial  and  depository  services.  This  competition  has  made  it  more  difficult  for  the  Bank  to 
make new loans and at times has forced us to offer higher deposit rates in our market areas.  We expect competition 
to increase in the future as a result of legislative, regulatory and technological changes and the continuing trend of 
consolidation  in  the  financial  services  industry.  Technological  advances,  for  example,  have  lowered  barriers  to 
market entry, enabled banks to expand their geographic reach by providing services over the Internet and enabled 
non-depository  institutions  to  offer  products  and  services  that  traditionally  have  been  provided  by  banks.  Recent 
changes  in  federal  banking  law  permit  affiliation  among  banks,  securities  firms  and  insurance  companies,  which 
also will change the competitive environment in which we conduct business. Some of the institutions with which 
we compete are significantly larger than us and, therefore, have significantly greater resources.  

A  real  estate  downturn  in  our  geographic  markets  could  hurt  our  business  because  a  majority  of  our  loans  are 
secured by real estate.  If real estate prices decline the value of real estate collateral securing our loans could be 
reduced.    Our  ability  to  recover  on  defaulted  loans  by  foreclosing  and  selling  real  estate  collateral  would  be 
diminished and we would likely suffer losses on defaulted loans.  As of December 31, 2006, approximately 60% of 
the book value of our loan portfolio consisted of loans collateralized by various types of real estate.  Substantially 
all  of  our  real  property  collateral  is  located  in  Missouri  and  Kansas.    Any  such  downturn  could  have  a  material 
adverse effect on our business, financial condition and results of operations. 

Recent  supervisory  guidance  on  commercial  real  estate  concentrations  could  restrict  our  activities  and  impose 
financial requirements or limitations on the conduct of business.   The office of the Comptroller of the Currency, 
The Board of Governors of the Federal Reserve System and the FDIC recently finalized joint supervisory guidance 
on sound risk management practices for concentrations in commercial real estate lending.  The guidance is intended 
to  help  ensure  that  institutions  pursuing  a  significant  commercial  real  estate  lending  strategy  remain  healthy  and 
profitable while continuing to serve the credit needs of the community. 

Our  commercial  real  estate  portfolio  as  of  December  31,  2006  meets  the  definition  of  a  commercial  real  estate 
concentration  as  set  forth  in  the  guidelines.  If  our  risk  management  practices  are  found  to  be  deficient,  it  could 
result in increased reserves and capital costs. 

Recent and possible future acquisitions could involve risks and challenges that could adversely affect our ability to 
achieve  our  profitability  goals  for  acquired  businesses  or  realize  anticipated  benefits  of  those  acquisitions.    We 
have experienced strong growth in the past several years and our strategy of future growth, while not dependent on, 
might  include  the  acquisition  of  banking  branches,  other  financial  institutions  and  other  wealth  management 
companies.    However,  we  cannot  assure  investors  that  we  will  be  able  to  identify  suitable  future  acquisition 
opportunities  or  finance  and  complete  any  particular  acquisition,  combination  or  other  transaction  on  acceptable 
terms  and  prices.    There  can  be  no  assurance  that  we  will  be  able  to  develop  and  integrate  acquired  businesses 
without adversely affecting our financial performance.  In addition, all acquisitions involve a number of risks and 
challenges that could adversely affect our ability to achieve anticipated benefits of acquisitions.  

Business Continuity Plans may not adequately anticipate all risks.  We are subject to events that could impact or 
disrupt  our  business,  although  our  goal  is  to  ensure  continuous  service  delivery  to  our  customers.    We  have 
undertaken  an  enterprise-wide  Business  Continuity  Plan  in  order  to  respond  to  and  guard  against  this  risk. 
However, no plan can fully eliminate such risk and there can be no assurance that our Plan will be successful.  

Future Government Regulation Could Hinder Future Performance.  The Company is a registered financial holding 
company  under  the  Bank  Holding  Company  Act  of  1956.    Accordingly,  both  the  Company  and  the  Bank  are 
subject  to  extensive  government  regulation,  legislation  and  control.    These  laws  limit  the  manner  in  which  the 
Company operates.  Management cannot predict whether, or the extent to which, the government and governmental 
organizations  may  change  any  of  these  laws  or  controls.    Changes  in  authoritative  accounting  guidance  by  the 

7

 
  
 
 
 
 
 
  
 
Financial Accounting Standards Board or other regulatory agencies could affect the Company in ways that are not 
currently  determinable.    Management  cannot  predict  how  any  of  these  changes  would  adversely  affect  the 
Company’s business. 

Federal  and  state  law  limits  the  Company’s  ability  to  declare  and  pay  dividends.    In  addition,  the  Board  of 
Governors  of  the  Federal  Reserve  System  may  impose  restrictions  on  the  Company’s  ability  to  declare  and  pay 
dividends on its common stock. 

Employees 
At  December 31,  2006  we  had  approximately  329  full-time  equivalent  employees.  None  of  the  Company’s 
employees  is  covered  by  a  collective  bargaining  agreement.    Management  believes  that  its  relationship  with  its 
employees is good. 

ITEM 1B: UNRESOLVED SEC COMMENTS 

Not applicable. 

ITEM 2: PROPERTIES 

Banking facilities  
Our executive offices are located at 150 North Meramec, Clayton, Missouri, 63105.  As of December 31, 2006, we 
had  four  banking  locations  in  the  St.  Louis  metropolitan  area  and  six  banking  locations  in  the  Kansas  City 
metropolitan  area.    The  Bank  owns  two  of  the  banking  facilities  and  leases  the  remainder.    In  March  2006,  the 
Company  purchased  its  operations  center  located  in  St.  Louis  County,  Missouri.    The  terms  of  the  leases  expire 
between 2009 and 2017 and most of the leases include one or more renewal options of 5 years.  All the leases are 
classified as operating leases.  We believe all our properties are in good condition. 

Wealth management facilities  
Enterprise Trust, a division of the Bank has offices in St. Louis and Kansas City.  Expenses related to the space 
used by Enterprise Trust are allocated to the Wealth Management segment.   

As of December 31, 2006, Millennium had 13 locations in 11 states throughout the United States.  The executive 
offices are located in Nashville, TN.  None of the locations is owned by Millennium.  The leases are classified as 
operating leases and expire in various years through 2011.   

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,  financial 
condition, results of operations or cash flows of the Company or any of its subsidiaries.  

ITEM 4: SUBMISSION OF MATTERS TO VOTE OF SECURITY HOLDERS 

No matters were submitted to a vote of security holders in the quarter ended December 31, 2006.

PART II 

ITEM 5: MARKET FOR COMMON STOCK AND RELATED STOCKHOLDER MATTERS AND 
ISSUER PURCHASE OF EQUITY SECURITIES 

Effective February 8, 2005, the Company’s common stock began trading on the NASDAQ National Market under 
the symbol “EFSC”.  Prior to that date, the common stock was not traded on an exchange but was traded on the 
Over-The-Counter  Bulletin  Board.  Below  are  the  dividends  declared  by  quarter  along  with  what  the  Company 
believes are the high and low closing sales prices for the common stock.  There may have been other transactions at 
prices not known to the Company.  As of February 21, 2007, the Company had 835 common stock shareholders of 
record  and  a  market  price  of  $29.75  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  common  stock  of  the  Company  are  entitled  to  receive  dividends  when  declared  by  the 
Company’s Board of Directors out of funds legally available for the purpose of paying dividends. The amount of 
dividends,  if  any,  that  may  be  declared  by  the  Company  will  be  dependent  on  many  factors,  including  future 
earnings,  bank  regulatory  capital  requirements  and  business  conditions  as  they  affect  the  Bank.    As  a  result,  no 
assurance can be given that dividends will be paid in the future with respect to the Company’s common stock.  In 
addition, the Company currently plans to retain most of its earnings for growth.   

Common Stock 
The authorized capital stock of the Company consists of 20,000,000 shares of common stock, par value $0.01 per 
share.    The  Company  has  asked  the  shareholders  to  increase  the  number  of  authorized  common  shares  to 
30,000,0000.  The shareholders will vote on this matter at the 2007 Annual Meeting.  Please see the Company’s 
Proxy Statement for its 2007 annual meeting to be held on Wednesday, April 18, 2007 for more information. 

Holders  of  the  common  stock  are  entitled  to  one  vote  per  share  on  all  matters  on  which  the  holders  of  common 
stock are entitled to vote. In all elections of directors, holders of common stock have the right to cast votes equaling 
the  number  of  shares  of  common  stock  held  by  such  stockholder  multiplied  by  the  number  of  directors  to  be 
elected.  All of such votes may be cast for a single director or may be distributed among the number of directors to 
be elected, or any two or more directors, as such stockholder elects. Holders of common stock have no preemptive, 
conversion,  redemption,  or  sinking  fund  rights.    In  the  event  of  a  liquidation,  dissolution  or  winding-up  of  the 
Company, holders of common stock are entitled to share equally and ratably in the assets of the Company, if any, 
remaining after the payment of all liabilities of the Company. 

The  Company  has  authorized  the repurchase of up to 500,000  shares of its common stock.  In the quarter ended 
December 31, 2006, the Company repurchased no shares of its common stock.

ITEM 7: MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
RESULTS OF OPERATIONS 

INTRODUCTION  
The objective of this section is to provide an overview of the financial condition and results of operations of the 
Company  for  the  three  years  ended  December 31,  2006.    It  should  be  read  in  conjunction  with  the  Consolidated 
Financial Statements, Notes and other financial data presented elsewhere in this report, particularly the information 
regarding the Company’s business operations described in Item 1. 

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 Note 1 – Significant Accounting Policies in 
this filing.   

The  Company  has  prepared  all  of  the  consolidated  financial  information  in  this  report  in  accordance  with  U.S. 
generally  accepted  accounting  principles  (“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.  
There can be no assurances that actual results will not differ from those estimates. 

Allowance for Loan Losses   
The Company maintains an allowance for loan losses (“the allowance”), which is intended to be management’s best 
estimate of probable inherent losses in the outstanding loan portfolio.   The allowance is based on management’s 
continuing  review  and  evaluation  of  the  loan  portfolio.      The  review  and  evaluation  combines  several  factors 
including:  consideration  of  past  loan  loss  experience;  trends  in  past  due  and  nonperforming  loans;  risk 
characteristics  of  the  various  classifications  of  loans;  existing  economic  conditions;  the  fair  value  of  underlying 
collateral; and other qualitative and quantitative factors which could affect probable credit losses.   

Because  current  economic  conditions  can  change  and  future  events  are  inherently  difficult  to  predict,  the 
anticipated  amount  of  estimated  loan  losses,  and  therefore  the  adequacy  of  the  allowance,  could  change 
significantly.    As  an  integral  part  of  their  examination  process,  various  regulatory  agencies  also  review  the 
allowance for loan losses.  These agencies may require that certain loan balances be charged off when their credit 
evaluations differ from those of management, based on their judgments about information available to them at the 
time of their examination.  The Company believes the allowance for loan losses is adequate and properly recorded 
in the consolidated financial statements. 

Derivative Financial Instruments   
The Company uses derivative financial instruments to assist in managing interest rate sensitivity.  The derivative 
financial instruments used are interest rate swaps.  Derivative financial 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.  Fair values 
are  generally  based  on  market  quotes.    The  accounting  for  changes  in fair value (gains or losses) of a derivative 
depends  on  whether  the  derivative  is  designated  and  qualifies  for  “hedge  accounting.”    In  accordance  with 
Statement  of  Financial  Accounting  Standards  No. 133  (“SFAS  No. 133”)  Accounting  for  Derivative  Instruments 
and Hedging Activities, the Corporation assigns derivatives to one of these categories at the purchase date:  

•  Cash Flow Hedges – Derivatives designated as cash flow hedges are accounted for at fair value.  The effective 
portion  of  the  change  in  fair  value  is  recorded  net  of  taxes  as  a  component  of  other  comprehensive  income 
(“OCI”) in shareholders’ equity.  Amounts recorded in OCI are subsequently reclassified into interest expense 
when the underlying transaction affects earnings.  The ineffective portion of the change in fair value is recorded 
in  noninterest  income.    The  swap  agreements  are  accounted  for  on  an  accrual  basis  with  the  net  interest 
differential  being  recognized  as  an  adjustment  to  interest  income  or  interest  expense  of  the  related  asset  or 
liability. 

12

 
 
 
 
 
 
 
 
•  Fair Value Hedges – Derivatives designated as fair value hedges, the fair value of the derivative instrument 
and related hedged item are recognized through the related interest income or expense, as applicable, except for 
the ineffective portion, which is recorded in noninterest income. All changes in fair value are measured on a 
quarterly basis.  The swap agreement is accounted for on an accrual basis with the net interest differential being 
recognized as an adjustment to interest income or interest expense of the related asset or liability.    

•  Non-Designated Hedges – Certain economic hedges are not designated as cash flow or as fair value hedges for 
accounting purposes.  These non-designated derivatives were entered into to provide interest rate protection on 
net interest income but do not meet hedge accounting treatment.  Changes in the fair value of these instruments 
are recorded in interest income at the end of each reporting period.     

The  judgments  and  assumptions  most  critical  to  the  application  of  this  accounting  policy  are  those  affecting  the 
estimation  of  fair  value  and  hedge  effectiveness.    Changes  in  assumptions  and  conditions  could  result  in  greater 
than expected inefficiencies that, if large enough, could reduce or eliminate the economic benefits anticipated when 
the  hedges  were  established  and/or  invalidate  continuation  of  hedge  accounting.    Greater  inefficiency  and 
discontinuation of hedge accounting can result in increased volatility in reported earnings.  For cash flow hedges, 
this would result in more or all of the change in the fair value of the affected derivative being reported in income. 
For fair value hedges, this would result in less or none of the change in the fair value of the derivative being offset 
by changes in the fair value of the underlying hedged asset or liability. 

Deferred Tax Assets 
The  Company  accounts  for  income  taxes  under  the  asset/liability  method.    Deferred  tax  assets  and  liabilities  are 
recognized  for  future  tax  effects  of  temporary  differences,  net  operating  loss  carry  forwards  and  tax  credits.   
Deferred tax assets are reduced if necessary, by a deferred tax asset valuation allowance.  A valuation allowance is 
established when in the judgment of management, it is more likely than not that such deferred tax assets will not 
become  realizable.    In  this  case,  the  Company  would  adjust  the  recorded  value  of  our  deferred  tax  assets, which 
would result in a direct charge to income tax expense in the period that the determination is made.  Likewise, the 
Company would reverse the valuation allowance when realization of the deferred tax asset is expected. 

Goodwill and Other Intangible Assets 
The  Company  accounts  for  goodwill  and  intangible  assets  according  to  Statement  of  Financial  Accounting 
Standards (“SFAS”) No. 142 “Goodwill and other Intangible Assets.”  The Company tests goodwill and intangible 
assets for impairment on an annual basis.  Such tests involve the use of estimates and assumptions.  Management 
believes  that  the  assumptions  utilized  are  reasonable.    However,  the  Company  may  incur  impairment  charges 
related  to  goodwill  in  the  future  due  to  changes  in  business  prospects  or  other  matters  that  could  affect  our 
assumptions.  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.  

The 2006 impairment evaluation of the goodwill and intangible balances did not identify any potential impairment; 
therefore,  no  goodwill  or  intangible  impairment  was  recorded  in  2006.    See  Note  9  –  Goodwill  and  Intangible 
Assets  in this filing for more information.     

EXECUTIVE SUMMARY 
This overview of management’s discussion and analysis highlights selected information in this document and may 
not contain all of the information that is important to you.  For a more complete understanding of trends, events, 
commitments, uncertainties, liquidity, capital resources and critical accounting estimates, you should carefully read 
this entire document. 

Net income increased 37% to $15.5 million, or $1.36 per fully diluted share compared to $11.3 million or $1.05 per 
fully diluted share in 2005.  Our four-year annual compound growth rate in earnings per share exceeded 27%.   

Banking – During 2006, our banking line of business posted strong loan and deposit growth.  We believe this is 
especially  impressive  in  light  of  the  intense  banking  competition  in  St.  Louis  and  Kansas  City.    As  some  of  the 
newer banks struggled to gain momentum and the larger banks sought to retain market share, we saw a good deal of 
aggressive loan and deposit pricing.  Throughout 2006, we remained disciplined in our pricing practices in order to 
maintain  our  interest  rate  margin  above  4.0%.    We  are  confident  in  our  ability  to  compete  successfully  in  this 
increasingly competitive environment. 

While organic growth remains our primary objective, during 2006, we announced two acquisitions: 

•  NorthStar  Bancshares,  Inc.  –  On  July  5,  2006  the  Company  completed  its  acquisition  of  NorthStar 
Bancshares, Inc. and it’s wholly owned subsidiary, NorthStar Bank, N.A.  On October 6, 2006, NorthStar 
Bank  was  merged into the Bank.  The NorthStar purchase expanded our footprint in Kansas City, which 

13

 
 
 
 
 
 
 
 
 
 
was  essential  for  us  to  become  a  larger  “participant”  in  that  market.    Subsequent  to  announcing  the 
acquisition,  two  senior  bankers  in  the  Kansas  City  market  agreed  to  join  our  team.    The  NorthStar 
acquisition contributed $154 million in loans and $146 million in deposits.   

•  Clayco Banc Corporation – On November 22, 2006 the Company executed an agreement to acquire Clayco 
Banc Corporation and its wholly owned banking subsidiary, Great American Bank for approximately $37.0 
million in cash and stock.  Clayco is headquartered in DeSoto, Kansas and operates two banking offices, 
one in DeSoto, Kansas and one in Claycomo, Missouri.  The transaction closed on February 28, 2007.   

The  staffs  and  branches  of  these  organizations  are  expected  to  provide  a  stronger  platform  for  our  banking  and 
wealth  management  businesses  in  Kansas  City.    Please  refer  to  Note  2  –  Acquisitions  and  Note  4  –  Subsequent 
Events in this filing for more information related to the acquisitions.   

Below is a summary of 2006 banking highlights: 

•  Loans  –  Total  portfolio  loans  grew  by  $309  million,  or  31%  and  ended  the  year  at  $1.3  billion.    During 
2006,  organic  loan  growth  (from  original  units  of  the  Bank)  grew  $155  million  –  50%  higher  than  2005 
loan growth of $104 million.   

•  Deposits  –  Total  deposits  grew  $199  million,  or  18%  and  the  bank  was  able  to  maintain  an  attractive 
deposit mix, with 18% of the total held in interest free demand deposits.  Core deposit growth in 2006 was 
in line with our expectations and reflected management’s decision to de-emphasize higher rate certificates 
of deposit.  Instead, we pursued lower cost transaction and relationship-based accounts primarily through 
our Treasury management products and services 

•  Asset quality – Asset quality was solid.  In 2006, we incurred $1.2 million of net charge-offs, or 0.10% of 
average loans.  Non-performing loans were $6.5 million or 0.49% of portfolio loans.  Nine of twelve non-
performing  relationships  related  to  the  NorthStar  acquisition.    The  allowance  for  loan  losses  was  $17.0 
million, or 1.30%, of portfolio loans vs. $13.0 million (also 1.30%) at the end of 2005.   

•  Net Interest Rate Margin – During 2006, average interest-earning assets increased $200 million, or 18%.  
The fully tax-equivalent net interest rate margin was 4.01% for 2006 versus 4.11% for 2005.  The decline 
in  the  net  interest  rate  margin  was  primarily  due  to  the  increasing  cost  of  deposits  that  more  than  offset 
higher earning asset yields.  In addition, a portion of the decline was due to the slightly dilutive impact of 
NorthStar’s net interest rate margin.   

Wealth Management – In 2006, the Wealth Management line of business delivered strong growth in revenues and 
earnings.   

•  Revenue  –  Wealth  Management  revenue  increased  by  $7.3  million,  or  112%,  due  to  $6.2  million  of 
incremental revenue from Millennium.  Factoring out Millennium, the Trust business increased income by 
$1.0 million or 14% for the year.  Assets under administration were $1.635 billion at December 31, 2006, 
an 18% increase over December 31, 2005.  The growth in Wealth Management revenue improved our ratio 
of  fee  income  to  revenue  from  17%  in  2005  to  25%  in  2006,  consistent  with  our  strategy  of  steadily 
diversifying our revenue sources.   

•  Earnings  –  Pre-tax  earnings  of  our  Trust  business  were  $1.3  million,  an  increase  of  38%  over  2005.  
Millennium,  in  its  first  full  year  with  Enterprise,  accounted  for  $0.08  of  2006  fully  diluted  earnings  per 
share  including  the  cost  of  acquisition-related  debt  issued  at  the  Company.    Millennium  generated  $3.5 
million of pre-tax earnings before intangible amortization and debt costs. 

RESULTS OF OPERATIONS ANALYSIS 

Net Interest Income 
Comparison of 2006 vs. 2005 
Net interest income is the primary source of the Company’s revenue.  Net interest income is the difference between 
interest income on earning assets, such as loans and securities, and the interest expense on interest-bearing deposits 
and other borrowings, used to fund interest earning and other assets.  The amount of net interest income is affected 
by  changes  in  interest  rates  and  by  the  amount  and  composition  of  interest-earning  assets  and  interest-bearing 
liabilities, such as the mix of fixed vs. variable rate loans.  When and how often loans and deposits mature and re-
price also impacts net interest income.   

Net interest spread and net interest rate margin are utilized to measure and explain changes in net interest income.  
Interest  rate  spread  is  the  difference  between  the  yield  on  interest-earning  assets  and  the  rate  paid  for  interest-

14

 
 
 
 
 
 
 
 
 
 
 
 
bearing liabilities that fund those assets.  The net interest rate margin is expressed as the percentage of net interest 
income  to  average  interest-earning  assets.    The  net  interest  rate  margin  exceeds  the  interest  rate  spread  because 
noninterest-bearing  sources  of  funds  (net  free  funds),  principally  demand  deposits  and  shareholders’  equity,  also 
support earning assets.   

The  Company’s  balance  sheet  and  resulting  net  interest  income  is  essentially  neutral to changes in interest rates.  
The shift in our loan portfolio over the past year toward a more balanced split between fixed and floating rate loans, 
along with higher levels of variable rate liabilities, has naturally increased our protection against significant interest 
rate changes, which management deems prudent given the current economic environment. 

Net interest income (on a tax equivalent basis) was $52.2 million for 2006, compared to $45.2 million for 2005, an 
increase  of  $7.0  million,  or  15%.    Total  interest  income  increased  $26.6  million  while  total  interest  expense 
increased $19.6 million.    

Average  interest-earning  assets  were  $1.3  billion,  an  increase  of  $200  million,  or  18%  over  $1.1  billion,  for  the 
same  period  in  2005.      Average  loans  increased  20%,  or  $195  million  to  $1.159  billion  from  $964  million.    For 
2006, interest income on loans increased $14.1 million from growth and $11.1 million due to the impact of the rate 
environment, for a net increase of $25.2 million versus 2005 (see “Rate/Volume” below.)   

Average interest-bearing liabilities increased $196 million, or 23% to $1.056 billion compared to $860 million for 
2005.  The growth in interest-bearing liabilities resulted from a $172 million increase in interest-bearing deposits, a 
$10.0 million increase in subordinated debentures, and a $14 million increase in borrowed funds including Federal 
Home Loan Bank (“FHLB”) advances.  We intentionally did not pursue higher rate certificates of deposit in our 
markets given the current interest rate environment, but continue to pursue lower cost transaction and relationship-
based accounts primarily through our treasury management products and services.  This resulted in lower deposit 
growth than in the prior year.  The combined bank deposit mix remains favorable with demand deposit accounts, 
that are non interest-bearing, representing 18% of average total deposits in a competitive deposit rate environment.  
For 2006, interest expense on interest-bearing liabilities increased $6.9 million due to this growth while the impact 
of rising rates increased interest expense on interest-bearing liabilities by $12.7 million versus 2005. 

Net interest rate margin (on a tax equivalent basis) for 2006 was 4.01%, compared to 4.11% in 2005.  Competitor 
pricing  and  the  interest  rate  environment  drove  up  the  cost  of  interest-bearing  liabilities  from  2.74%  in  2005  to 
4.09% in 2006.  The net interest rate margin increases were primarily in money market and consumer certificates of 
deposit  rates.      A  portion  of  the  decline  in  the  margin  was  due  to  the  slightly  dilutive  impact  of  NorthStar’s  net 
interest rate margin.   

Comparison of 2005 vs. 2004    
Net interest income (on a tax equivalent basis) was $45.2 million for 2005, an increase of $8.0 million or 22% from 
2004.  Throughout 2005, slightly less than two-thirds of the loan portfolio floated with the prime rate.  Throughout 
2005, we were asset-sensitive, which means our assets generally re-priced faster than our liabilities.  The fed funds 
rate  increases  during  late  2004  and  2005  by  the  Federal  Open  Markets  Committee  (“FOMC”)  had  a  positive 
influence on our net interest income and margin.   

Average interest-earning assets were $1.1 billion in 2005, an increase of $133 million or 14% from 2004. Loans 
accounted for the majority of the growth, increasing by $117 million or almost 14% to $964 million on average in 
2005.  For 2005, interest income on loans increased $7.0 million from growth and $10.7 million due to the impact 
of the rate environment, for a net increase of $17.7 million versus 2004.   

Average interest-bearing liabilities were $860 million in 2005, an increase of $112 million or 15% from 2004.  The 
growth in interest-bearing liabilities resulted from an $85 million increase in interest-bearing deposits, a $4 million 
increase in subordinated debentures, and a $23 million increase in borrowed funds including FHLB advances.  The 
growth  in  earning  assets  was  also  supported  by  a  $16  million  or  9%  increase  in  average  noninterest-bearing 
deposits.  For 2005, interest expense on interest-bearing liabilities increased $2.4 million due to this growth and the 
impact of rising rates increased interest expense on interest-bearing liabilities by $8.9 million versus 2004. 

The net interest rate margin for 2005 was 4.11%, compared to 3.84% in 2004.  The yield on interest-earning assets 
increased 1.15% from 5.10% to 6.25%.   The cost of interest-bearing liabilities increased from 1.63% in 2004 to 
2.74%.    The  increase  in  cost  of  funds  was  primarily  due  to  increases  in  money  market  and  certificate  of  deposit 
rates given competitor pricing and the increasing interest rate environment.

NOTE:  The change in interest due to both rate and volume has been allocated to rate and volume changes
              in proportion to the relationship of the absolute dollar amounts of the change in each.

Provision for loan losses.   The provision for loan losses was $2.1 million for 2006 compared to $1.5 million for 
2005.  The increase was due to stronger loan growth and higher non-performing loan levels.    

The provision for loan losses was $1.5 million for 2005 compared to $2.2 million for 2004.  The decrease in the 
provision  for  loan  losses  was  due  to  lower  non-performing  loan  levels,  continued  strengthening  local  economies 
and continued low delinquency rates. 

See  the  sections  below  captioned  “Loans”  And  “Allowance  for  Loan  Losses”  for  more  information  on  our  loan 
portfolio and asset quality.

Comparison 2006 vs. 2005 
Total  Wealth  Management  income  increased  112%  during  2006.    This  includes  an  incremental  increase  of  $6.2 
million  of  commission  income  earned  by  Millennium.    Excluding  Millennium,  Trust  revenue  increased  $1.0 
million, or 14% for the year.  Our ratio of fee income to total revenue at December 31, 2006 was 25% compared to 
17%  in  2005.    This  increase  is  consistent  with  our  strategy  of  steadily  diversifying  our  revenue  sources.    Assets 
under administration increased to $1.635 billion in 2006, an 18% increase over 2005.    

Increases  in  Service  charges  on  deposit  accounts  were  primarily  due  to  NorthStar  activity  along  with  increased 
account activity.  These increases were somewhat offset by a rising earnings credit rate on commercial accounts.  
Higher fee volumes on debit cards, merchant processing and health savings accounts along with NorthStar deposit 
fee income contributed to the increase in Other service charges and fee income.   

During  the  second  half  of  2005,  we  elected  to  reposition  a  portion  of  our  investment  portfolio  by  selling  and 
reinvesting approximately $29.0 million of investments.  We realized losses of $494,000 on these sales.  Increases 
in  market  rates  for  the  two  through  four-year  maturity  ranges  and  the  company’s  overall  interest  rate  sensitivity 
presented an opportunity to strengthen the expected total return on portfolio investments for 2006 and 2007.   

The Company sold a foreclosed real estate property during the third quarter of 2005 for a gain of $91,000. 

Comparison 2005 vs. 2004 
Total  Wealth  Management  revenue  increased  53%  during  2005.    The  increase  includes  $780,000  of  commission 
income  earned  by  Millennium  in  2005  after  the  October  acquisition.    Excluding  Millennium,  Trust  revenue 
increased $1.5 million, or 35% for the year.  The increase was the result of a 25% growth rate in net Trust client 
relationships  as  well  as  having  a  full  year  of  revenue  generated  from  the  Wealth  Products  Group  (“WPG”)  unit.  
Favorable  market  conditions  and  client  mix  also  factored  in  this  growth.    Assets  under  administration  increased 
almost $225.0 million in 2005, but were offset by $250.0 million of assets managed in a special common trust fund 
account which were distributed to clients as called for by contract in the fourth quarter of 2005.   

Service charges on deposit accounts were basically unchanged year over year due to a rising earnings credit rate on 
commercial accounts, which was offset by increased account activity.

The Company’s efficiency ratio improved from 64% to 61% in 2006.  Noninterest expenses increased 21% or $7.1 
million in 2006.  Approximately $3.0 million of this increase is related to the addition of Millennium, which was 
acquired in October 2005.  Noninterest expense also includes $2.5 million of NorthStar expenses incurred since the 
July 2006 acquisition.  Excluding these amounts, noninterest expenses increased only $1.6 million or 5%.   

Comparison of 2006 vs. 2005    
Employee  compensation  and  benefits.    Our  compensation  programs  reflect  our  philosophy  that  carefully  selected 
associates who are properly trained, directed and motivated will dramatically impact our performance and represent 
a sustaining competitive advantage.   We compensate our associates in ways to attract and retain top performers, 
and  to  provide  base  salary,  incentives  and  rewards  that  incent  the  behaviors  consistent  with  a  high-performing 
company.  Over the last four years, we have implemented a disciplined process for managing the performance of 
our associates against defined business goals and results.   The process includes frequent and candid performance 
feedback, measures individual contributions, differentiates individual performance and reinforces contribution with 
highly differentiated rewards.  Two major components of our compensation program are the variable-pay incentive 
bonus pool and the Long-Term Incentive Plan (“LTIP”).  

Effective January 1, 2005, the Board of Directors adopted a new LTIP.  Under the terms of the plan, the Company 
awards restricted share units (“RSU’s”) to selected personnel based on the Company’s three year rolling average 
increase in earnings per share in comparison to a peer group of approximately 150 financial institutions.  RSU’s are 
expensed annually as they vest.   

Millennium employee compensation and benefits increased $1.3 million over 2005 amounts due to a full year of 
expenses  versus  only  two  months  in  2005.    Employee  compensation  and  benefits  includes  $1.3  million  for 
NorthStar  in  2006.    Excluding  Millennium  and  NorthStar,  employee  compensation  and  benefits  increased  3%  or 
$543,000.  The  increase  is  due  to  increased  salary  and  related  benefits,  including  LTIP  expenses,  of  existing 
associates along with expenses related to new senior level banking associates and new associates in various areas of 
our organization including marketing, wealth management and other support areas.  These increases were offset by 
declines in wealth management commissions and the deferral of direct loan origination costs.  

All other expense categories.  All other expense categories include $1.2 million for NorthStar in 2006.  All other 
expense categories include $1.7 million of incremental expenses related to Millennium.    Excluding Millennium 
and NorthStar, all other noninterest expenses increased $1.1 million, or 9% over 2005.  

The  addition  of  Millennium  and  NorthStar  contributed  $169,000  and  $236,000,  respectively,  to  the  increase  in 
occupancy expense.  Occupancy expense also includes scheduled rent increases on various Company facilities and 
related leasehold improvements completed at the Operations Center.  In December 2006, the Bank’s Kansas City 

19

 
 
 
 
 
 
 
 
 
 
 
Plaza  location  moved.    This  resulted  in  $200,000  of  leasehold  improvement  write-offs,  which  were  recorded  in 
Occupancy expense.   

Furniture and equipment increases were due to the new St. Charles bank location, Millennium, NorthStar and the 
expansion of the Operations Center.   

Data processing expenses increased due to upgrades to the Company’s AS400, licensing fee increases for our core 
banking system as a result of our increased asset size and increased maintenance fees for various Company systems. 
In  addition,  several  new  systems  designed  to  improve  efficiency  in  various  support  areas,  such  as  Finance  and 
Human Resources, were purchased and implemented in 2006. Expenses incurred to convert NorthStar technology 
to our platform have been capitalized and will be amortized according to the Company’s depreciation policies. 

Communication expenses increased $100,000 due to Millennium and $71,000 due to NorthStar.   

Meals and entertainment increases of $136,000 were related to Millennium.  An additional $71,000 was related to 
NorthStar.    The  remaining  increase  was  due  to  increased  travel  between  St.  Louis  and  Kansas  City  along  with 
additional client meetings, including Enterprise University classes, which were held offsite.   

Amortization of intangibles related to Millennium was $912,000 in 2006 compared to $152,000 in 2005.  In 2006, 
NorthStar  intangible  amortization  was  $216,000.    In  2005,  the  Company  also  recognized  non-compete  expenses 
related to the former CEO, who resigned in 2002.  See Note 9 – Goodwill and Intangible Assets in this filing for 
more information related to the intangible amortization.   

Other  noninterest  expense  includes  increases  in  charitable  contributions  and  loan-related  expenses  along  with 
increases in general operating expenses such as supplies, publications, and employee education.    

Comparison of 2005 vs. 2004    
Our efficiency ratio, which expresses noninterest expense, as a percentage of tax-equivalent net interest income and 
other income, was 64% for 2005, improved from 67% in 2004.  The improved efficiency ratio was due to revenue 
growth and cost management across all lines of business.   Noninterest expense for 2005 includes three months of 
Millennium operations subsequent to the acquisition.   

Noninterest expenses grew 17% or $5 million in 2005 over 2004.  Excluding expenses incurred for Millennium of 
$504,000  and  $152,000  of  amortization  expenses  related  to  the  acquisition,  noninterest  expenses  increased  $4.3 
million, or 15%.   

Employee compensation and benefits.  2005 expenses under the Company’s incentive bonus programs, including 
the 401(k) match program, which is tied to performance targets, increased $1.3 million over 2004 from $2.9 million 
to $4.2 million.  Driving this increase were the Company’s EPS growth in 2005, asset quality statistics, and growth 
in  deposits  and  wealth  management  revenue  and  referrals.      Compensation  expense  related  to  the  RSU’s  was 
$483,000 in 2005.    

Growth  in  wealth  management  revenues  increased  commissions  by  $594,000.    Salaries  and  benefits  of  new 
associates,  annual  merit  increases,  along  with  increases  in  medical  and  disability  insurance  costs  contributed 
$784,000  to  the  increase.    Recruiting  fees  increased  $115,000  over  2004.    Actual  expenses  related  to  the  2004 
acceleration of vesting on stock options were $15,000.  The remaining increase was attributable to Millennium.  

All other expense categories.  Excluding the increase in employee compensation and benefits and Millennium, all 
other noninterest expenses increased $1 million, or 9% over 2004.  

Occupancy expense increases were due to scheduled rent increases on various Company facilities along with a full 
year  of  rent  for  additional  space  leased  at  the  Company’s  Operation  Center  and  related  leasehold  improvements 
completed  at  the  Operations  Center.    The  new  St.  Charles  City  banking  location  and  the  addition  of  Millennium 
also contributed to the increase.   

Data processing expenses increased due to upgrades to our AS400 computer system, licensing fee increases for our 
core  banking  system  as  a  result  of  our  increased asset size and increased maintenance fees for various Company 
systems.    Furniture  and  equipment  increases  were  due  to  the  new  St.  Charles  bank  location,  Millennium  and  the 
expansion of the Operations Center.

The increase in professional, legal and consulting includes acquisition related activities, as well as, expenses for the 
further  development  of  our  business  continuity  plan,  development  of  bank  products,  human  resource  consulting, 
investment management consulting and various legal issues.   

Meals and entertainment increases were due to the addition of Millennium, various client related events and more 
employee travel between the St. Louis and Kansas City banking locations.   

In 2005, director compensation was restructured to more competitive levels including restricted stock units granted 
to the directors.  Mark to market adjustments for outstanding Stock Appreciation Rights paid to the directors also 
increased over 2004. 

In  2005  and  2004,  the  Company  recognized  non-compete  expenses  related  to  the  former  CEO,  who  resigned  in 
2002.   

During  2005,  our  directors  and  officers  liability  insurance  coverage  was  renewed  which  resulted  in  increased 
coverage amounts and insurance premiums.  The growth in Bank deposits also increased FDIC insurance expenses.  

In 2004, we expensed unamortized debt issuance costs related to the refinancing of $11.0 million of Trust Preferred 
Securities (“TRUPS”).   

Minority Interest in Net Income of Consolidated Subsidiary 
On October 21, 2005, the Company acquired a 60% controlling interest in Millennium.  The Company records the 
40% non-controlling interest in Millennium, related to Millennium’s results of operations, in minority interest on 
the consolidated statements of income.  Contractually, the Company is entitled to a priority return of 23.1% pre-tax 
on its current $15.0 million investment in Millennium.  During 2006, the Company adjusted minority interest by 
$861,000 to recognize its priority return in line with its contractual rights.   

Income Taxes 
In  2006,  the  Company  recorded  income  tax  expense  of  $8.3  million  on  pre-tax  income  of  $23.8  million,  an 
effective  tax  rate  of  35.0%.    During  2006,  $230,000  of  tax  reserves  were  reversed  through  Income  tax  expenses 
related to certain state tax positions taken in 2002.  The expiration of the statute of limitations for the 2002 tax year 
warranted this release.   

The 2005 effective tax rate for the Company was 35.8% compared to 33.2% in 2004.  During 2004 the Company 
recognized  a  $241,000  reversal  of  the  remaining  deferred  tax  valuation  allowance  related  to  Merchant  Banking 
losses in 2001.  In addition during 2004, the Company recognized state income tax refunds of $163,000 related to 
amendments of prior state income tax returns.  Exclusive of these non-recurring items, the effective tax rate in 2004 
would have been approximately 36.5%. 

FINANCIAL CONDITION 
Comparison for the years ended December 31, 2006 and 2005 
Total assets at December 31, 2006 were $1.5 billion, an increase of $249 million, or 19%, over total assets of $1.3 
billion at December 31, 2005.  The increase in total assets was driven by a $309 million, or 31%, increase in loans 
with $154 million of the loan increase due to the NorthStar acquisition.    

Investment securities were $111 million at December 31, 2006 compared to $136 million at December 31, 2005.  
At December 31, 2005, investment securities included $40 million of short-term discount agency securities, which 
matured in January 2006 and were not replaced.   

Goodwill and intangible assets were $36 million at December 31, 2006, compared to $17 million at December 31, 
2005,  an  increase  of  $19  million.    The  increase  in  goodwill  and  intangible  assets  was  primarily  related  to  the 
purchase of NorthStar.   See Note 9 – Goodwill and Intangible Assets in this filing for more information. 

At  December  31,  2006,  deposits  were  $1.3  billion,  an  increase  of  $199  million,  or  18%,  from  $1.1  billion  at 
December 31, 2005.  NorthStar added $146 million, including $61.0 million of Brokered CD’s.   Total Brokered 
CD’s at December 31, 2006 were $104 million.  During 2006, we did not pursue client-based higher rate certificate 
of deposits in our markets given the current interest rate environment, and instead pursued lower cost transaction 
and relationship-based accounts primarily through our treasury management products and services.  This resulted in 
lower deposit growth than in prior years.  The combined bank deposit mix remains favorable with demand deposits 
accounts representing 18% of total deposits in a competitive deposit rate environment.

We  plan  to  continue  utilizing  FHLB  advances  and  brokered  certificates  of  deposit  to  fund  shortfalls  due  to  loan 
demand.  At December 31, 2006, FHLB advances were $27.0 million compared to $28.6 million at December 31, 
2005.   There were no short-term FHLB advances outstanding at December 31, 2006 or 2005.    

Junior subordinated debentures increased by $4.1 million due to a pooled trust offering that closed on July 29, 2006 
through  a  statutory  trust  established  by  the  Company.    In  conjunction  with  the  issuance  of  the  trust  preferred 
offering,  the  Company  issued  $4.0  million  in  junior  subordinated  debentures  to  the  trust.    The  issuance  of  the 
additional  junior  subordinated  debentures  was  to  partially  fund  the  acquisition  of  NorthStar.    The  Company  also 
borrowed $4.0 million against its line of credit with U.S. Bank to help fund the acquisition of NorthStar.  

Federal funds (“Fed funds”) sold were $7.1 million at December 31, 2006 compared to $65 million at December 
31, 2005.  Strong loan fundings near year-end reduced our overall liquidity levels at December 31, 2006. 

Fourth Quarter 2006 Discussion 
The Company earned $4.4 million in net income for the fourth quarter ended December 31, 2006, a $1.6 million 
increase over net income of $2.8 million for the same period in 2005.   

The tax-equivalent net interest rate margin was 3.98% for the fourth quarter of 2006 as compared to 4.06% for the 
same  period  in  2005.    Net  interest  income  in  the  fourth  quarter  of  2006  increased  $2.2  million  from  the  fourth 
quarter of 2005.  This increase in net interest income was the result of a $7.4 million increase in interest income 
offset  by  a  $5.2  million  increase  in  interest  expense.    The  yield  on  average  interest-earning  assets  increased  to 
7.57%  during  the  fourth  quarter  of  2006  as  compared  to  6.66%  during  the  same  period  in  2005.    The  cost  of 
interest-bearing  liabilities  increased  to  4.42%  for  the  fourth  quarter  of  2006  from  3.27%  for  the  same  period  in 
2005.  This increase is attributed mainly to an increase in money market interest rates and certificates of deposit due 
to the rate environment.   

The provision for loan losses was $350,000 in the fourth quarter of 2006 versus $70,000 in 2005.  The increase was 
due to stronger loan growth and higher non-performing loan levels. 

Noninterest  income  was  $4.7  million  during  the  fourth  quarter  of  2005,  a  $2.1  million  increase  over  noninterest 
income of $2.6 million for the same period in 2005.  Millennium earned $1.9 million of commission income during 
fourth  quarter  2006  compared  to  $780,000  during  the  fourth  quarter  of  2005.    In  the  fourth  quarter  of  2005, 
$408,000  of  net  realized  losses  from  the  sale  of  securities  were  recognized.    The  remaining  increase  is  due  to 
increased  revenues  from  the  Trust  division  of  the  Bank  and  higher  fee  volumes  associated  with  debit  cards, 
merchant processing, health savings accounts and other products. 

Noninterest  expenses  were  $11.8  million  during  the  fourth  quarter  of  2006  versus  $9.9  million  during  the  same 
period  in  2005,  a  $1.9  million  increase.    Approximately  $530,000  of  the  increase  was  related  to  the  addition  of 
Millennium in late October 2005.  Millennium increases included one additional month of expenses (three months 
during  2006  versus  only  two  months  in  2005)  along  with  increases  in  salaries,  performance-based  variable 
compensation and various operating expenses. An additional $1.2 million of the increase was related to NorthStar 
(including  $215,000  of  intangible  amortization.)    The  remaining  increase  was  primarily  due  to  additional 
compensation  expense  tied  to  our  incentive  bonus  programs,  which  is  tied  to  performance  targets  such  as  EPS 
growth, deposit and loan growth, asset quality statistics, and increases in wealth management revenue and referrals. 

Income tax expense was $2.1 million during the fourth quarter of 2006 versus $1.6 million in the same period in 
2005.  The effective tax rate was 32.2% for the fourth quarter of 2006 compared to 36.0% for the fourth quarter of 
2005.  During the fourth quarter of 2006, we released $230,000 of state tax reserves where the statute of limitations 
had expired.

Loans 
Total loans, less unearned loan fees, increased $309 million, or 30.1% during 2006.  This includes $154 million in 
loans from the acquisition of NorthStar.  The Company’s lending strategy emphasizes commercial, residential real 
estate,  real  estate  construction  and  commercial  real  estate  loans  to  small  and  medium  sized  businesses  and  their 
owners  in  the  St.  Louis  and  Kansas  City  metropolitan  markets.    Consumer  lending  is  minimal.    A  common 
underwriting policy is employed throughout the Company.  Lending to these small and medium sized businesses 
are  riskier  from  a  credit  perspective  than  lending  to  larger  companies,  but  the risk tends to be offset with higher 
loan pricing and ancillary income from cash management activities.   

The Company has a targeted hiring program designed to attract and retain experienced commercial middle market 
bankers in both the St. Louis and Kansas City markets.  As a result of this strategy the Company has continued to 
target  larger  and  more  sophisticated  commercial  and  industrial  and  commercial  real  estate clients.  It is expected 
that the Company’s average relationship size will continue to increase, resulting in greater efficiencies, as the same 
level of cost can originate and service larger average relationships and their related higher revenues.

Commercial and industrial loans are made based on the borrower’s character, experience, general credit strength, 
and ability to generate cash flows for repayment from income sources, 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.    Commercial  and  industrial  loans  are  primarily 
made  to  borrowers  operating  within  the  manufacturing  industry.    This  industry  sector  represents  approximately 
$114  million,  or  approximately  9%  of  the  Bank’s  loan  portfolio  at  December  31,  2006.    The  largest  component 
within this industry sector are loans to aerospace product and parts manufacturers.   

Real estate loans are also based on the borrower’s character, but more emphasis is placed on the estimated collateral 
values.  Real estate commercial loans are mainly for owner-occupied business and industrial properties, multifamily 
properties, and other commercial properties on which income from the property is the primary source of repayment.  
Credit  risk  on  these  loan  types  is  managed  in  a  similar  manner  to  commercial  loans  and  real  estate  construction 
loans by employing sound underwriting guidelines.  As of December 31, 2006, approximately $285 million of real 
estate loans, or 22% of the Bank’s loan portfolio are secured by commercial and multi-family properties that are 
located within the Bank’s two primary metropolitan markets.  These loans are underwritten based on the cash flow

coverage of the property, typically meet the Bank’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 construction for eventual sale.  At December 31, 2006, the largest component of this category consists 
of loans to residential builders.  These loans represent $107 million, or 8%, of the Bank’s total loans.  The majority 
of these loans are granted to builders within the Bank’s primary markets.  The loans are secured by single family 
residences, of which, approximately $20 million, are constructed for display or inventory and are not pre-sold.  The 
Bank  requires  third  party  disbursement  on  the  majority  of  its  builder  portfolio  and  the  Bank  reviews  projects 
regularly for progress status.    

Real estate residential loans include residential mortgages (which consist of loans that, due to size, do not qualify 
for  conventional  home  mortgages,  that  the  Company  sells  into  the  secondary  market  and  second  mortgages)  and 
home equity lines.  Residential mortgage loans are usually limited to a maximum of 80% of collateral value. 

Consumer  and  other  loans  represent  loans  to  individuals  on  both  a  secured  and  unsecured  nature.    Credit  risk  is 
controlled by thoroughly reviewing the creditworthiness of the borrowers on a case-by-case basis.   

Portfolio loans held for sale relate to loans originated by the Southeast Kansas branches that were sold on April 4, 
2003. 

Factors  that  are  critical  to  managing  overall  credit  quality  are  sound  loan  underwriting  and  administration, 
systematic  monitoring  of  existing  loans  and  commitments,  effective  loan  review  on  an  ongoing  basis,  early 
identification of potential problems, an adequate allowance for loan losses, and sound non-accrual and charge-off 
policies. 

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, 2006, no significant concentrations exceeding 10% of total loans existed in the 
Company's loan portfolio, except as described above.

As indicated in the above maturity table, half of the lending business is done on a variable rate basis based on prime 
or  the  London  Interbank  Offered  Rate  (“LIBOR”.)    In  addition,  most  loan  originations  have  one  to  three  year 
maturities.  While the loan relationship has a much longer life, the shorter maturities allow the Company to revisit 
the underwriting and pricing on each relationship periodically. 

Fixed rate loans comprise approximately 50% of the loan portfolio at December 31, 2006 versus 36% at the end of 
2005. This trend is consistent with the flat to inverted yield curve environment, as borrowers are choosing fixed rate 
loans  with  one  to  three  year  terms  that  have  lower  interest  rates  than  variable  rate  alternatives.  Management 
monitors this mix as part of its interest rate risk management. See “Interest Rate Risk” section. 

Allowance for Loan Losses 
The loan portfolio is the primary asset subject to credit risk.  Credit risk is controlled and monitored through the use 
of lending standards, a thorough review of potential borrowers, and ongoing review of loan payment performance.  
Active asset quality administration, including early problem loan identification and timely resolution of problems, 
further ensures appropriate management of credit risk and minimization of loan losses.  Credit risk management for 
each loan type is discussed briefly in the section entitled “Loans.” 

The  allowance  for  loan  losses  represents  management’s  estimate  of  an  amount  adequate  to  provide  for  probable 
credit  losses  in  the  loan  portfolio  at  the  balance  sheet  date.    Management’s  evaluation  of  the  adequacy  of  the 
allowance  for  loan  losses  is  based  on  management’s  ongoing  review  and  grading  of  the  loan  portfolio, 
consideration of past loss experience, trends in past due and nonperforming loans, risk characteristics of the various 
classifications of loans, existing economic conditions, the fair value of underlying collateral, and other factors that

considers the allowance for loan losses a critical accounting policy (see section “Critical Accounting Policies”). 

The  following  table  summarizes  changes  in  the  allowance  for  loan  losses  arising  from  loans  charged  off  and 
recoveries on loans previously charged off, by loan category, and additions to the allowance charged to expense.

At  the  acquisition  date,  the  NorthStar  allowance  for  loan  losses  was  $3.1  million  or  1.85%  of  total  loans.    This 
percentage, along with existence of the Reserved Credit Escrow (described in Note 2 – Acquisitions in this filing), 
demonstrates the higher level of credit risk inherent in that loan portfolio. 

Loans charged off are subject to continuous review, and specific efforts are taken to achieve maximum recovery of 
principal, accrued interest, and related expenses. 

The Company’s credit management policies and procedures focus on identifying, measuring, and controlling credit 
exposure.    These  procedures  employ  a  lender-initiated  system  of  rating  credits,  which  is  ratified  in  the  loan 
approval  process  and subsequently tested in internal loan reviews and regulatory bank examinations. The system 
requires rating all loans at the time they are made, at each renewal date and as conditions warrant. 

Adversely  rated  credits,  including  loans  requiring  close  monitoring,  which  would  normally  not  be  considered 
criticized  credits  by  regulators,  are  included  on  a  monthly  loan  watch  list.  Other  loans  are  added  whenever  any 
adverse circumstances are detected which might affect the borrower’s ability to meet the terms of the loan.  This 
could be initiated by any of the following:  

1)  delinquency of a scheduled loan payment,  
2)  deterioration in the borrower’s financial condition identified in a review of periodic financial statements, 
3)  decrease in the value of collateral securing the loan, or

4)  change in the economic environment in which the borrower operates. 

Loans on the watch list require detailed loan status reports, including recommended corrective actions, prepared by 
the  responsible  loan  officer  every  three  months.    These  reports  are  then  discussed  in  formal  meetings  with  the 
Senior Credit Administration Officer, Chief Credit Officer and Chief Executive Officer of the Bank. 

Downgrades of loan risk ratings may be initiated by the responsible loan officer, internal loan review, or the credit 
analyst  department  at  any  time.    Upgrades  of  certain  risk  ratings  may  only  be  made  with  the  concurrence  of  the 
Senior Credit Administration Officer, Chief Credit Officer and Loan Review Officer. 

In determining the allowance and the related provision for loan losses, three principal elements are considered:  

1)  specific allocations based upon probable losses identified during a quarterly review of the loan portfolio, 
2)  allocations based principally on the Company’s risk rating formulas, and 
3)  an unallocated allowance based on subjective factors. 

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  collateral  exposure,  if  they  are  collateral 
dependent for collection.  Otherwise, discounted cash flows are estimated and used to assign loss. 

The  second  element  reflects  the  application  of  our  loan  rating  system.    This  rating  system  is  similar  to  those 
employed by state and federal banking regulators.  Loans are rated and assigned a loss allocation factor for each 
category  that  is  consistent  with  our  historical  losses,  adjusted  for  environmental  factors.    The  higher  the  rating 
assigned to a loan, the greater the allocation percentage that is applied. 

The unallocated allowance is based on management’s evaluation of conditions that are not directly reflected in the 
determination  of  the  formula  and  specific  allowances.    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 or portfolio segments.  The conditions evaluated in connection with the unallocated allowance include the 
following: 

credit quality trends (including trends in nonperforming loans expected to result from existing conditions); 
collateral values; 
loan volumes and concentrations; 
competitive factors resulting in shifts in underwriting criteria; 
specific industry conditions within portfolio segments; 
recent loss experience in particular segments of the portfolio; 

(cid:131)  general economic and business conditions affecting our key lending areas; 
(cid:131) 
(cid:131) 
(cid:131) 
(cid:131) 
(cid:131) 
(cid:131) 
(cid:131)  bank regulatory examination results; and 
(cid:131) 

findings of our internal loan review department. 

Executive management reviews these conditions quarterly in discussion with our entire lending staff.  To the extent 
that any of these conditions is evidenced by a specifically identifiable problem credit or portfolio segment 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  portfolio  segment.    Where  any of these conditions is not evidenced by a specifically 
identifiable problem credit or portfolio segment as of the evaluation date, management’s evaluation of the probable 
loss related to such condition is reflected in the unallocated allowance. 

Based  on  this  quantitative  and  qualitative  analysis,  provisions  are  made  to  the  allowance  for  loan  losses.    Such 
provisions are reflected in our consolidated statements of income. 

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, designed to assess the adequacy of the allowance for loan losses, 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.  Because each of the criteria used is subject 
to  change,  the  allocation  of  the  allowance  for  loan  losses  is  made  for  analytical  purposes  and  is  not  necessarily 
indicative  of  the  trend  of  future  loan  losses  in  any  particular  loan  category.    The  total  allowance  is  available  to 
absorb losses from any segment of the portfolio.  Management continues to target and maintain the allowance for 
loan losses equal to the allocation methodology plus an unallocated portion, as determined by economic conditions 
and other qualitative and quantitative factors affecting the Company’s borrowers, as described above.

Prior to 2004, the methods of calculating the allowance requirements had not changed significantly over time. The 
reallocations among different categories of loans that appear between periods were the result of the redistribution of 
the individual loans that comprise the aggregate portfolio due to the factors listed above.  However, the perception 
of risk with respect to particular loans within the portfolio will change over time as a result of the characteristics 
and  performance  of  those  loans,  overall  economic  and  market  trends,  and  the  actual  and  expected  trends  in 
nonperforming  loans.    Consequently,  while  there  are  no  specific  allocations  of  the  allowance  resulting  from 
economic or market conditions or actual or expected trends in nonperforming loans, these factors are considered in 
the initial assignment of risk ratings to loans, subsequent changes to those risk ratings and to a lesser extent in the 
size of the unallocated allowance amount. 

Beginning  in  2004,  as  a  part  of  an  overall  effort  to  further  improve  its  risk  assessment;  the  Company  refined  its 
methodology  with  special  attention  to  the  unallocated  allowance.    The  unallocated  allowance  is  based  on  factors 
that  cannot  necessarily  be  associated  with  a specific loan or loan category.  In its 2004 assessment, management 
focused on the following factors and conditions: 

(cid:131)  There  is  a  level  of  imprecision  necessarily  inherent  in  the  estimates  of  expected  loan  losses,  and  the 
unallocated reserve gives reasonable assurance that this level of imprecision in our formula methodologies 
is adequately provided for. 

(cid:131)  With respect to the real estate sector, management considered the continued weakness in the commercial 

office market with vacancy rates continuing to remain high and rents continuing to remain soft. 

(cid:131)  Pressures  to  maintain  and  grow  the  loan  portfolio  in  a  slower  economic  environment  with  increasing 
competition from de novo institutions and larger competitors have to some degree affected credit granting 
criteria adversely.  The Company monitors the disposition of all credits, which have been approved through 
its Executive Loan Committee in order to better understand competitive shifts in underwriting criteria.   
(cid:131)  While the Bank’s target client has not changed, the Bank is focusing more of its calling efforts on larger 
middle  market  commercial  and  industrial  companies.    This  move  “up  market”  results  in  larger  average 
loans per client, and generally more complex credit structures. 

While the Company has no significant specific industry concentration risk, analysis at the time showed that over 
60%  of  the  loan  portfolio  was  dependent  on  real  estate  collateral.    The  Company  has  policies,  guidelines,  and 
individual  risk  ratings  in  place  to  control  this  exposure  at  the  transaction  level.    However,  the  percentage  of  the 
portfolio  secured  by  commercial  real  estate  increased  from  28%  at  December  31,  2002  to  37%  at  December  31, 
2004.    Given  the  trend  of  rising  rates  inherent  in  the  current  economic  cycle  and  the  likely  adverse  impacts  on 
borrowers’ debt service coverage ratios, management believed it was prudent to increase the unallocated allowance 
component. 

Additionally,  the  Company  continues  to  be  committed  to  a  strategy  of  acquiring  relationships  with  larger 
commercial and industrial companies.  The percentage of the portfolio represented by these clients increased from 
25% at December 31, 2002 to 28% at December 31, 2004.   Management believed it was prudent to increase the 
percentage  of  the  unallocated  allowance  to  cover  the  risks  inherent  in  the  higher  average  loan  size  of  these 
relationships. 

Finally, management believed that the level of competition for credit relationships had increased substantially over 
the  prior  year  in  both  of  our  primary  markets.    During  2004,  the  entry  of  National  City  Bank  into  the  St.  Louis 
market along with six new banking charters are examples of the increased level of competition.  To the extent that 
substantially  increased  levels  of  competition  for  credit  may  inherently  result  in  an  increased  level  of  credit  risk, 
management believed it was prudent to increase the Company’s unallocated allowance component.

As a result of the above analysis, management increased the unallocated allowance by $1.3 million from 2003 to 
2004.    The  factors  noted  for  2004  were  still  applicable  at  December  31,  2005  and  2006.    Additionally,  the 
residential real estate markets in both St. Louis and Kansas City are experiencing a slow down in new home sales, 
thus  affecting  both  builder  profitability  and  the  level  of  unsold  inventory  on  the  market.    The  potential  risks  of 
softening residential real estate markets have been offset in part by a strengthening commercial and industrial real 
estate market in both St. Louis and Kansas City, and the relatively static levels of interest rates in the second half of 
2006.  The unallocated reserve amount as a percentage of the total reserve has ranged from 14% to 19% in the last 
three years, consistent with the various factors noted above.   

Nonperforming assets include non-accrual loans, loans with payments past due 90 days or more and still accruing 
interest, restructured loans and foreclosed real estate.  The following table presents the categories of nonperforming 
assets and certain ratios as of the dates indicated:

Nonperforming loans are defined as loans on non-accrual status, loans 90 days or more past due but still accruing, 
and restructured loans.  Loans are 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 collectibility 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 and income is recorded only to the extent that 
interest payments are subsequently received in cash and a determination has been made that the principal balance of 
the loan is collectible.  If collectibility 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 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.    Also 
included  in  nonperforming  loans  are  “restructured”  loans.    Restructured  loans  involve  the  granting  of  some 
concession to the borrower involving the modification of terms of the loan, such as changes in payment schedule or 
interest rate.  

Nonperforming loans were $6.5 million at December 31, 2006, an increase of $5.1 million over 2005.  Two loans in 
the  Kansas  City  market  secured  by  real  estate  represent  $3.6  million  of  this  increase.    Six  of  the  remaining  ten 
relationships  on  non-accrual  at  December  31,  2006  and  approximately  50%  of  the  nonperforming  loan  balances 
relate to smaller relationships acquired in the NorthStar transaction. 

At December 31, 2005, the nonperforming loans consisted of five accounts with two credits accounting for 68% of 
the total.  At December 31, 2004 and 2003, approximately 36% and 37%, respectively, of the nonperforming loans 
related to a printing company and the remainder consisted of five and eight different borrowers, respectively.  At 
December  31,  2002,  $1.2  million  of  the  restructured  loans  related  to  an  auto  dealership  that  had  financial 
difficulties.

Foreclosed real estate valued at $1.5 million represents several single family residences and lots in Kansas City that 
were  former  NorthStar  loan  relationships.    All  properties  are  presently  being  marketed  for  resale  either  by 
residential real estate firms or through our network of residential builders. 

The  Company’s  non-accrual  loans  and  restructured  loans  meet  the  definition  of  “impaired  loans”  under  U.S. 
GAAP.    As  of  December  31,  2006,  2005  and  2004,  the  Company  had  twelve,  five,  and  eight  impaired  loan 
relationships, respectively, all of which are considered potential problem loans as well.   

Management believes that the allowance for loan losses is adequate. 

Investment Securities 
At  December  31,  2006,  the  investment  securities  portfolio  was  $111.2  million,  or  7%  of  total  assets.    Our  debt 
securities  portfolio  is  primarily  comprised  of  U.S.  government  agency  obligations,  mortgage-backed  pools, 
collateralized mortgage obligations and municipal bonds.  Our equity investments primarily consist of stock in the 
FHLB of Des Moines.  The size of the investment portfolio is generally 5-10% of total assets and will vary within 
that  range  based  on  liquidity.    Typically,  management  classifies  securities  as  available  for  sale  to  maximize 
management flexibility, although securities may be purchased with the intention of holding to maturity.  Securities 
available-for-sale are carried at fair value, with related unrealized net gains or losses, net of deferred income taxes, 
recorded as an adjustment to equity capital.

At  December  31,  2005,  Obligations  of  U.S.  government  agencies  included  $40.0  million  of  short-term  discount 
agency notes that matured in January 2006.  These investments were used as an alternative to overnight funds to 
obtain higher yield given the excess liquidity. 

The Company had no securities classified as trading at December 31, 2006, 2005 or 2004.

Yields  on  tax  exempt  securities  are  computed  on  a  taxable  equivalent  basis  using  a  tax  rate  of  36%.    Expected 
maturities will differ from contractual maturities, as borrowers may have the right to call on repay obligations with 
or without prepayment penalties.

We continued to experience loan and deposit growth due to aggressive direct calling efforts of relationship officers. 
Management has pursued closely-held businesses whose management desires a close working relationship with a 
locally-managed, full-service bank.  Due to the relationships developed with these customers, management views 
large deposits from this source as a stable deposit base.  The Company also uses certificates of deposit sold to retail 
customers of regional and national brokerage firms (i.e. brokered certificates of deposit) to help fund its growth.  At 
December 31, 2006 and 2005, the Company had $104 million and $64 million in brokered certificates of deposit, 
respectively. 

Maturities of certificates of deposit of $100,000 or more are as follows:

Liquidity and Capital Resources 
The objective of liquidity management is to ensure the Company has the ability to generate sufficient cash or cash 
equivalents in a timely and cost-effective manner to meet its commitments as they become due.  Funds are available 
from  a  number  of  sources,  such  as  from  the  core  deposit  base  and  from  loans  and  securities  repayments  and 
maturities.    Additionally,  liquidity  is  provided  from  sales  of  the  securities  portfolio,  lines  of  credit  with  major 
banks, the Federal Reserve and the FHLB, the ability to acquire large and brokered deposits and the ability to sell 
loan participations to other banks. 

The Company’s liquidity management framework includes measurement of several key elements, such as the loan 
to  deposit  ratio,  wholesale  deposits  as  a  percentage  of  total  deposits,  and  various  dependency  ratios  used  by 
banking  regulators.    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.   

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 an 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 process. 

While core deposits and loan and investment repayments are principal sources of liquidity, funding diversification 
is  another  key  element  of  liquidity  management.    Diversity  is  achieved  by  strategically  varying  depositor  types, 
terms, funding markets, and instruments.

We manage the parent Company’s liquidity to provide the funds necessary to pay dividends to shareholders, service 
debt,  invest  in  the  Bank  as  necessary,  and  satisfy  other  operating  requirements.    The  parent  Company’s  primary 
funding  sources  to  meet  its  liquidity  requirements  are  dividends  from  subsidiaries,  borrowings  against  its  $11 
million line of credit with a major bank, and proceeds from the issuance of equity (i.e. stock option exercises).   

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.  

Another source of funding for the parent company includes the issuance of subordinated debentures.  In October of 
2005, the Company issued $10.0 million of subordinated debentures as part of a TRUPS at a fixed rate of 6.14% for 
five years.  Following the five-year period, the TRUPS will pay a variable rate of three-month LIBOR plus 1.44% 
that reprices quarterly.  In July of 2006, the Company issued $4.0 million of subordinated debentures as part of a 
TRUPS  at  a  floating  rate  equal  to  three-month  LIBOR  +  1.60%.    The  TRUPS  are  classified  as  subordinated 
debentures,  but  qualify  as  regulatory  capital.    The  related  interest  expense  is  tax-deductible  and  is  recorded  as 
interest expense in the Company’s consolidated financial statements.   See Note 11 – Subordinated Debentures in 
this filing for more information. 

Investment  securities  are  an  important  tool to the Company’s liquidity objective.  As of December 31, 2006, the 
entire investment portfolio was available for sale.  Of the $111 million investment portfolio available for sale, $32 
million  was  pledged  as  collateral  for  public  deposits,  treasury,  tax  and  loan  notes,  and  other  requirements.    The 
remaining securities could be pledged or sold to enhance liquidity, if necessary. 

The  Bank  has  a  variety  of  funding  sources  (in  addition  to  key  liquidity  sources,  such  as  core  deposits,  loan 
repayments, loan participations sold, and investment portfolio sales) available to increase financial flexibility.  At 
December  31,  2006,  the  Bank  had  $130  million  available  from  the  FHLB  of  Des  Moines  under  a  blanket  loan 
pledge, subject to the Bank not being in default on its credit agreement, and $165 million available from the Federal 
Reserve under a pledged loan agreement.  The Bank also has access to over $70 million in overnight federal funds 
lines purchased from various banking institutions.  Finally, because the Bank continues to be a “well-capitalized” 
institution, it has the ability to sell certificates of deposit through various national or regional brokerage firms, if 
needed. 

Over  the  normal  course  of  business,  the  Company  enters  into  certain  forms  of  off-balance  sheet  transactions, 
including  unfunded  loan  commitments  and  letters  of  credit.    These  transactions  are  managed  through  the 
Company’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  Company  has  $480  million  in  unused  loan 
commitments  as  of  December  31,  2006.    While  this  commitment  level  would  be  very  difficult  to  fund  given  the 
Company’s current liquidity resources, we know that the nature of these commitments is such that the likelihood of 
funding demand is very low.   

For  the  year  ended  December  31,  2006  and  2005,  net  cash  provided  by  operating  activities  was  materially 
consistent.    Net  cash  used  in  investing  activities  was  $123  million  in  2006  versus  $132  million  in  2005.    The 
decrease  of  $9  million  was  primarily  due  to  a  reduction  in  investment  security  activity.    Net  cash  provided  by 
financing  activities  was  $37  million  in  2006  versus  $206  million  in  2005.    The  change  in  cash  provided  by 
financing  activities  is  due  to  less  deposit  growth  in  2006  and  paydowns  of  long-term  Federal  Home  Loan  Bank 
advances. 

Risk-based  capital  guidelines  were  designed  to  relate  regulatory  capital  requirements  to  the  risk  profile  of  the 
specific institution and to provide for uniform requirements among the various regulators.  Currently, the risk-based 
capital guidelines require the Company to meet a minimum total capital ratio of 8.0% of which at least 4.0% must 
consist  of  Tier  1  capital.    Tier  1  capital  consists  of  (a) common  shareholders’  equity  (excluding  the  unrealized 
market  value  adjustments  on  the  available-for-sale  securities  and  cash  flow  hedges),  (b)  qualifying  perpetual 
preferred stock and related additional paid in capital subject to certain limitations specified by the FDIC, and (c) 
minority interests in the equity accounts of consolidated subsidiaries less (d) goodwill, (e) mortgage servicing rights 
within certain limits, and (f) any other intangible assets and investments in subsidiaries that the FDIC determines 
should be deducted from Tier 1 capital.  The FDIC also requires a minimum leverage ratio of 3.0%, defined as the 
ratio of Tier 1 capital to average total assets for banking organizations deemed the strongest and most highly rated 
by  banking  regulators.    A  higher  minimum  leverage  ratio  is  required  of  less  highly  rated  banking  organizations.  
Total capital, a measure of capital adequacy, includes Tier 1 capital, allowance for loan losses, and subordinated 
debentures.

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 
Company’s Asset/Liability Management Committee and approved by the Company’s Board of Directors are used 
to  monitor  exposure  of  earnings  at  risk.    General  interest  rate  movements  are  used  to  develop  sensitivity  as  the 
Company  feels  it  has  no  primary  exposure  to  a  specific  point  on  the  yield  curve.    These  limits  are  based  on  the 
Company’s exposure to a 100 basis points and 200 basis points immediate and sustained parallel rate move, either 
upward or downward. 

Interest Rate Risk 
In  order  to  measure  earnings  sensitivity  to  changing  rates,  the  Company  uses  a  static  gap  analysis  and  earnings 
simulation model.   

The  static  gap  analysis  starts  with  contractual  repricing  information  for  assets,  liabilities,  and  off-balance  sheet 
instruments.    These  items  are  then  combined  with  repricing  estimations  for  administered  rate  (interest-bearing 
demand  deposits,  savings,  and  money  market  accounts)  and  non-rate  related  products  (demand  deposit  accounts, 
other  assets,  and  other  liabilities)  to  create  a  baseline  repricing  balance  sheet.    In  addition,  mortgage-backed 
securities are adjusted based on industry estimates of prepayment speeds.   

33

 
 
 
 
 
 
 
The  following  table  represents  the  estimated  interest  rate  sensitivity  and  periodic  and  cumulative  gap  positions 
calculated  as  of  December  31,  2006.    Significant  assumptions  used  for  this  table  included:  loans  will  repay  at 
historic  repayment  rates;  interest-bearing  demand  accounts  and  savings  accounts  are  interest  sensitive  due  to 
immediate repricing, and fixed maturity deposits will not be withdrawn prior to maturity.  A significant variance in 
actual results from one or more of these assumptions could materially affect the results reflected in the table.

(1) Adjusted for the impact of the interest rate swaps.

At December 31, 2006, the Company was asset sensitive on a cumulative basis for all periods except 1 year based 
on contractual maturities.  Asset sensitive means that assets will reprice faster than liabilities. 

Along with the static gap analysis, determining the sensitivity of short-term future earnings to a hypothetical plus or 
minus 100 and 200 basis point parallel rate shock can be accomplished through the use of simulation modeling.  In 
addition  to  the  assumptions  used  to  create  the  static  gap,  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 plus or minus 100 basis points parallel rate 
shock. 

The  resulting  simulations  for  December  31,  2006,  projected  that  net  interest  income  would  increase  by 
approximately 0.4% if rates rose by a 100 basis point parallel rate shock, and projected that the net interest income 
would decrease by approximately 2.6% if rates fell by a 100 basis point parallel rate shock. 

The  Company  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,  2006,  the  Company  had  $17  million  in  notional 
amount  of  outstanding  interest  rate  swaps  to  reduce  interest  rate  risk.    Derivative  financial  instruments  are  also 
discussed in Note 7 – Derivatives in this filing.

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 at December 31, 2006 were as follows: 

(in thousands)
Operating leases
Certificates of deposit
Subordinated debentures
Federal Home Loan Bank advances
Commitments to extend credit
Standby letters of credit

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.  Derivative liabilities are not included as contractual cash obligations as their fair 
value does not represent the amounts that may ultimately be paid under these contracts.   

Effects of New Accounting Standards 
In  July  2006,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  Interpretation  No.  48,  Accounting  for 
Uncertainty in Income Taxes, an Interpretation of FAS No. 109, Accounting for Income Taxes.  The interpretation 
defines the threshold for recognizing the financial impact of uncertain tax positions in accordance with FAS 109.   
A company is required to recognize, in its financial statements, the best estimate of the impact of a tax position only 
if  that  position  is  “more-likely-than-not”  of  being  sustained  on  audit  based  solely  on  the  technical  merits  of  the 
position on the reporting date. In evaluating whether the “more-likely-than-not” recognition threshold has been met, 
the  Interpretation  requires  the  assumption  that  the  tax  position  will  be  evaluated  during  an  audit  by  taxing 
authorities.  The  term  “more-likely-than-not”  is  defined  as  a  likelihood  of  more  than  50  percent.    Individual  tax 
positions that fail to meet the recognition threshold will generally result in either (a) a reduction in the deferred tax 
asset  or  an  increase  in  a  deferred  tax  liability  or  (b)  an  increase  in  a  liability  for  income  taxes  payable  or  the 
reduction of an income tax refund receivable. The impact may also include both (a) and (b). This Interpretation also 
provides  guidance  on  disclosure,  accrual  of  interest  and  penalties,  accounting  in  interim  periods,  and  transition.  
The Interpretation is effective for reporting periods beginning after December 15, 2006.  The Company does not 
expect  FASB  Interpretation  No.  48  to  have  a  material  impact  on  the  Company's  financial  position  or  results  of 
operations. 

In  September  2006,  the  Securities  and  Exchange  Commission  (“SEC”) issued  Staff  Accounting  Bulletin  No. 108 
(“SAB  No.  108”)  to  clarify  consideration  of  the  effects  of  prior  year  errors  when  quantifying  misstatements  in 
current  year  financial  statements  for  the  purpose  of  quantifying  materiality.  SAB  No.  108  requires  issuers  to 
quantify misstatements using both the “rollover” and “iron curtain” approaches and requires an adjustment to the 
current year financial statements in the event that after the application of either approach and consideration of all 
relevant quantitative and qualitative factors, a misstatement is determined to be material. SAB No. 108 is effective 
for  fiscal  years  beginning  after  November 15, 2006. We are in the process of determining the effect, if any, that 
SAB 108 will have on our consolidated financial statements.  The Company’s analysis under SAB No. 108 of prior 
year  and  current  year  misstatements  did  not  result  in  any  adjustment  to  prior  year  or  current  year  financial 
statements. 

In  September  2006,  the  FASB  issued  FAS  No. 157,  Fair  Value  Measurements.    FAS No. 157 defines fair value, 
establishes  a  framework  for  measuring  fair  value  in  generally  accepted  accounting  standards,  and  expands 
disclosures about fair value measurements. FAS No. 157 is effective for financial statements issued for fiscal years

beginning  after  November 15,  2007,  and  interim  periods  within  those  fiscal  years.  We  do  not  expect  that  the 
adoption of FAS No. 157 will have a material impact on our financial condition or results of operations.

Disclosure Controls and Procedures 

As  of  December  31,  2006,  under  the  supervision  and  with  the  participation  of  the  Company’s  Chief  Executive 
Officer  (“CEO”)  and  the  Chief  Financial  Officer  (“CFO”),  management  has  evaluated  the  effectiveness  of  the 
design and operation of the Company’s disclosure controls and procedures pursuant to Exchange Act Rule 13a-15.  
Based on that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures were 
effective as of December 31, 2006, to ensure that information required to be disclosed in the Company’s periodic 
SEC filings is processed, recorded, summarized and reported when required.  There were no significant changes in 
the Company’s internal controls or in the other factors that could significantly affect those controls subsequent to 
the date of the evaluation.

Management’s Report on Internal Control over Financial Reporting 

The  Company’s  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over 
financial  reporting.    The  Company’s  internal  control  over  financial  reporting  is  a  process  designed  under  the 
supervision  of  the  CEO and CFO to provide reasonable  assurance regarding reliability of financial reporting and 
preparation of the Company’s financial statements for external reporting purposes in accordance with U.S. GAAP. 

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting 
as  of  December  31,  2006,  based  on  the  criteria  set  forth  by  the  Committee  of  Sponsoring  Organization  of  the 
Treadway  Commission  (COSO)  in  “Internal  Control-Integrated  Framework.”    Based  on  the  assessment, 
management  determined  that,  as  of  December  31,  2006,  the  Company’s  internal  control  over  financial  reporting 
was effective based on these criteria. 

Management’s  assessment  of  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of 
December 31, 2006 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in 
their report included in this Form 10-K.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Shareholders 
Enterprise Financial Services Corp: 

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

We  conducted  our  audit  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether  effective  internal  control  over  financial  reporting  was  maintained  in  all  material  respects.  Our  audit 
included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  evaluating  management's 
assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such 
other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable 
basis for our opinion. 

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

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

In  our  opinion,  management's  assessment  that  the  Company  maintained  effective  internal  control  over  financial 
reporting as of December 31, 2006, is fairly stated, in all material respects, based on criteria established in Internal 
Control—Integrated  Framework issued by COSO. Also, in our opinion, the Company maintained, in all material 
respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established in 
Internal Control—Integrated Framework issued by COSO. 

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United States), the consolidated balance sheets of the Company as of December 31, 2006 and 2005, and the related 
consolidated statements of income, shareholders’ equity and comprehensive income, and cash flows for each of the 
years  in  the  three-year  period  ended  December  31,  2006,  and  our  report  dated  March  12,  2007  expressed  an 
unqualified opinion on those consolidated financial statements.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Shareholders 
Enterprise Financial Services Corp: 

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Enterprise  Financial  Services  Corp  and 
subsidiaries (the Company) as of December 31, 2006 and 2005, and the related consolidated statements of income, 
shareholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended 
December 31, 2006. 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  conducted  our  audits  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether the financial statements are free of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the 
accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall 
financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion. 

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

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United  States),  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of  December  31, 
2006,  based  on  criteria  established  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of 
Sponsoring  Organizations  of  the  Treadway  Commission,  and  our  report  dated  March  12,  2007  expressed  an 
unqualified opinion on management’s assessment of, and the effective operation of, internal control over financial 
reporting.

NOTE 1—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

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

Business 
Enterprise Financial Services Corp (the “Company” or “EFSC”) is a financial holding company that provides a full 
range of banking and wealth management services to individual and corporate customers located in the St. Louis 
and Kansas City metropolitan markets through its subsidiary, Enterprise Bank & Trust (the “Bank”).  In addition, as 
of October 21, 2005, the Company owns 60% of Millennium Brokerage Group, LLC (“Millennium”) through its 
wholly-owned  subsidiary,  Millennium  Holding  Company,  Inc.  Millennium  is  headquartered  in  Nashville, 
Tennessee and operates life insurance advisory and brokerage operations from 13 offices serving life agents, banks, 
CPA firms, property and casualty groups, and financial advisors in 49 states.  Millennium is included in the Wealth 
Management segment along with Enterprise Trust, a division of the Bank, which provides fee-based trust, personal 
financial planning, estate planning, and corporate planning services to the Company’s target market. 

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 the Bank are subject 
to  the  regulations  of  certain  federal  and  state  agencies  and  undergo  periodic  examinations  by  those  regulatory 
agencies.  Millennium and the investment management industry in general are subject to extensive regulation in the 
United  States  at  both  the  federal  and  state  level,  as  well  as  by  self-regulatory  organizations  such  as  the  National 
Association  of  Securities  Dealers,  Inc.  The  Securities  and  Exchange  Commission  is  the  federal  agency  that  is 
primarily responsible for the regulation of investment advisers.    

Basis of Financial Statement Presentation 
The consolidated financial statements of the Company and its subsidiaries have been prepared in conformity with 
U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) and conform to predominant practices within the 
banking  industry.    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.  
Estimates that are particularly susceptible to significant change in a short period of time include the determination 
of the allowance for loan losses, derivative financial instruments, deferred tax assets and goodwill.  Actual amounts 
could differ from those estimates. 

Consolidation 
The consolidated financial statements include the accounts of the Company, Bank (100% owned) and Millennium 
(60%  owned).    Acquired  businesses  are  included  in  the  consolidated  financial  statements  from  the  date  of 
acquisition.    All  material  intercompany  accounts  and  transactions  have  been  eliminated.    Minority  ownership 
interests  are  reported  in  our  Consolidated  Balance  Sheets  as  a  liability.    The  minority  ownership  interest  of  our 
earnings  or  loss,  net  of  tax,  is  classified  as  “Minority  interest  in  net  income  of  consolidated  subsidiary”  in  our 
Consolidated  Statements  of  Income.      For  more  information,  please  refer  to  “Minority  Interest  in  Net  Income  of 
Consolidated Subsidiary” discussed in Item 2 – Management’s Discussion and Analysis of Financial Condition and 
Results of Operations included in this filing.   

Investments in Debt and Equity Securities 
The Company currently classifies investments in debt and equity securities as follows: 

•  Available for sale - includes debt and marketable equity securities not classified as held to maturity or trading 
(i.e., investments which the Company has no present plans to sell but may be sold in the future under different 
circumstances). 

Debt  and  equity  securities  classified  as  available  for  sale  are  carried  at  estimated  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.   

A  decline  in  the  market  value  of  any  available  for  sale  security  below  cost  that  is  deemed  other-than-temporary 
results in a charge to earnings and the establishment of a new cost basis for the security.  To determine whether an 
impairment  is  other-than-temporary,  the  Company  considers  whether  it  has  the  ability  and  intent  to  hold  the 
investment  until  a  market  price  recovery  and  considers  whether  evidence  indicating  cost  of  the  investment  is 
recoverable outweighs evidence to the contrary.  Evidence considered in this assessment includes the reasons for 
the  impairment,  the  severity  and  duration  of  the  impairment,  changes  in  value  subsequent  to  year-end,  and 
forecasted performance of the investee.

For available for sale securities, premiums and discounts are amortized or accreted over the 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  for  securities  classified  as  available  for  sale  are  included  in  earnings  and  are 
derived using the specific identification method for determining the cost of securities sold. 

Cash and Cash Equivalents 
At December 31, 2006 and 2005, approximately $8,200,000 and $12,600,000, respectively, of cash and due from 
banks represented required reserves on deposits maintained by the Bank in accordance with Federal Reserve Bank 
requirements. 

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 without 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 that are sold in the 
secondary  market  are  sold  principally  under  programs  with  the  Government  National  Mortgage  Association 
(“GNMA”) or the Federal National Mortgage Association (“FNMA”).  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, 2006 and 2005.  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 income. 

Interest and Fees on Loans 
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 opinion, negatively impacts the collectibility of the loan.  
Subsequent  interest  payments  received  on  such  loans  are  applied  to  principal  if  any  doubt  exists  as  to  the 
collectibility  of  such  principal;  otherwise,  such  receipts  are  recorded  as  interest  income.    Loans  are  returned  to 
accrual status when management believes full collectibility of principal and interest is expected. 

Loan origination fees and direct origination costs are deferred and recognized over the lives of the related loans as a 
yield adjustment using a method, which approximates the interest method.   

Allowance For Loan Losses 
The allowance for loan losses is increased by provisions 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.    Management’s  approach,  which  provides  for  general  and  specific  allowances,  is 
based  on  current  economic  conditions,  past  losses,  collection  experience,  risk  characteristics  of  the  portfolio, 
assessments  of  collateral  values  by  obtaining  independent  appraisals  for  significant  properties,  and  such  other 
factors which, in management’s judgment, deserve current recognition in estimating loan losses. 

Management  believes  the  allowance  for  loan  losses  is  adequate  to  absorb  probable  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 the Bank to add to the allowance for loan losses based on their judgments and interpretations of information 
available to them at the time of their examinations. 

Accounting for Impaired Loans  
A loan is considered impaired when it is probable the Bank will be unable to collect all amounts due, both principal 
and interest, according to the contractual terms of the loan agreement.  The Bank’s non-accrual loans, loans past 
due greater than 90 days and still accruing, and restructured loans qualify as “impaired loans.”  When measuring 
impairment, the expected future cash flows of an impaired loan are discounted at the loan’s effective interest rate.  
Alternatively, impairment is 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 recorded when cash is received 
and only if principal is considered to be fully collectible. 

Other Real Estate  
Other real estate represents property acquired through foreclosure or deeded to the Bank in lieu of foreclosure on 
loans  on  which  the  borrowers  have  defaulted  as  to  the  payment  of  principal  and  interest.    Other  real  estate  is 

46

 
 
 
 
 
 
 
 
 
 
recorded  on  an  individual  asset  basis  at  the  lower  of  cost  or  fair  value  less  estimated  costs  to  sell.    Subsequent 
reductions in fair value are expensed or recorded in a valuation reserve account through a provision against income.  
Subsequent increases in the fair value are recorded through a reversal of the valuation reserve. 

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

Goodwill and Other Intangible Assets 
Goodwill represents the excess of costs over fair value of assets of businesses acquired.  Goodwill and intangible 
assets  acquired  in  a  purchase  business  combination  and  determined  to  have  an  indefinite  useful  life  are  not 
amortized,  but  instead  tested  for  impairment  at  least  annually.  Intangible  assets  with  estimable  useful  lives  are 
amortized  over  their  respective  estimated  useful  lives  to  their  estimated  residual  values,  and  reviewed  for 
impairment. 

Intangibles,  consisting  of  customer  lists  and  agreements  not  to  compete,  are  amortized  using  the  straight-line 
method over the estimated useful lives of approximately 5 years.  Core deposit intangibles are amortized using an 
accelerated method over an estimated useful life of approximately 10 years.   

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 by 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 disposed group classified as held for sale are presented separately in the 
appropriate asset and liability sections of the balance sheet. 

Derivative Instruments and Hedging Activities 
The Company uses derivative instruments to assist in the management of interest rate sensitivity and to modify the 
repricing,  maturity  and  option  characteristics  of  certain  assets  and  liabilities.    Generally,  the  only  derivative 
instruments used by the Company are interest rate swaps.   Derivative instruments are required to be measured at 
fair value and recognized as either assets or liabilities in the financial statements. Fair value represents the payment 
the Company would receive or pay if the item were sold or bought in a current transaction. Fair values are generally 
based on market quotes. 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.” In accordance with Statement of 
Financial  Accounting  Standards  No. 133,  (“FAS  No.  133”)  Accounting  for  Derivative  Instruments  and  Hedging 
Activities, the Company assigns derivatives to one of these categories at the purchase date: fair value hedge, cash 
flow hedge or non-designated derivatives. FAS No. 133 requires an assessment of the expected and ongoing hedge 
effectiveness of any derivative designated a fair value hedge or cash flow hedge. Derivatives are included in other 
assets and other liabilities in the Consolidated Statements of Condition.  

The  following  is  a  summary  of  the  Company’s  accounting  policies  for  derivative  instruments  and  hedging 
activities. 

•  Cash Flow Hedges – Derivatives designated as cash flow hedges are accounted for at fair value.  The effective 
portion  of  the  change  in  fair  value  is  recorded  net  of  taxes  as  a  component  of  other  comprehensive  income 
(“OCI”) in shareholders’ equity.  Amounts recorded in OCI are subsequently reclassified into interest expense 
when the underlying transaction affects earnings.  The ineffective portion of the change in fair value is recorded 
in  noninterest  income.    The  swap  agreements  are  accounted  for  on  an  accrual  basis  with  the  net  interest 
differential  being  recognized  as  an  adjustment  to  interest  income  or  interest  expense  of  the  related  asset  or 
liability. 

47

 
 
 
 
 
 
 
 
 
 
•  Fair Value Hedges – Derivatives designated as fair value hedges, the fair value of the derivative instrument 
and related hedged item are recognized through the related interest income or expense, as applicable, except for 
the ineffective portion, which is recorded in noninterest income. All changes in fair value are measured on a 
quarterly basis.  The swap agreement is accounted for on an accrual basis with the net interest differential being 
recognized as an adjustment to interest income or interest expense of the related asset or liability.    

•  Non-Designated Hedges – Certain economic hedges are not designated as cash flow or as fair value hedges for 
accounting purposes.  These non-designated derivatives represent interest rate protection on net interest income 
but  do  not  meet  hedge  accounting  treatment.    Changes  in  the  fair  value  of  these  instruments  are  recorded  in 
interest income at the end of each reporting period.     

Income Taxes 
The Company and its subsidiaries file consolidated federal income tax returns.  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.  A valuation allowance is recognized if the Company determines it is more likely than not that 
all  or  some  portion  of  the  deferred  tax  asset  will  not  be  recognized.    In  estimating  accrued  taxes,  the  Company 
assesses the relative merits and risks of the appropriate tax treatment considering statutory, judicial and regulatory 
guidance in the context of the tax position. 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. 

Stock-Based Compensation 
The Company maintains a number of stock-based incentive programs, which are discussed in more detail in Note 
17 – Compensation Plans in this filing.  Prior to 2006, the Company applied the intrinsic value-based method, as 
outlined  in  Accounting  Principles  Board  Opinion  No. 25,  Accounting  for  Stock  Issued  to  Employees,  (“APB 
No. 25”)  and  related  interpretations,  in  accounting  for  stock  options  granted  under  these  programs.  Under  the 
intrinsic  value-based  method,  no  compensation  expense  was  recognized  if  the  exercise  price  of  the  Company’s 
employee  stock  options  was  equal  to  or  greater  than  the  market  price  of  the  underlying  stock  on  the  date  of  the 
grant. Accordingly, prior to 2006, no compensation cost was recognized in the consolidated statements of income 
on  stock  options  granted  to  employees,  since  all  options  granted  under  the  Company’s  share  incentive  programs 
had an exercise price equal to the market value of the underlying common stock on the date of the grant. 

In 2005, the Company began awarding restricted stock units (“RSU’s”) as part of a new long-term incentive plan.  
Beginning  in  2005,  compensation  expense,  based  on  grant  date  fair  value  of  the  RSU’s,  is  recognized  in  the 
consolidated statements of income over the vesting period.   

Effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123(R) (“FAS 
No. 123(R)”)  Share-based  Payment.  This  statement  replaces  FAS  No. 123,  Accounting  for  Stock-Based 
Compensation,  and  supersedes  APB  No. 25.  FAS  No. 123(R)  requires  that  all  stock-based  compensation  be 
recognized as an expense in the financial statements and that such cost be measured at the grant date fair value for 
all  equity  classified  awards.  The  Company  adopted  this  statement  using  the  modified prospective method, which 
requires  the  Company  to  recognize  compensation  expense  on  a  prospective  basis  for  all  outstanding  unvested 
awards.  Therefore,  prior  period  financial  statements  have  not  been  restated.  Under  this  method,  in  addition  to 
reflecting compensation expense for share-based awards granted after the adoption date, expense is also recognized 
to reflect the remaining service period of awards that had been included in pro forma disclosures in prior periods. 
FAS  No. 123(R)  also  requires  that  excess  tax  benefits  related  to  stock  option  exercises  be  reflected  as  financing 
cash  inflows.    Therefore,  excess  tax  benefits  related  to  stock  option  exercises  in  2005  and  2004  are  reflected  in 
operating  activities.  The  total  income  tax  benefit  recognized  for  share-based  compensation  arrangements  was 
$525,000 in 2006.

The  following  table  illustrates  the  effect  on  net  income  if  the  fair-value-based  method  had  been  applied  to  all 
outstanding and unvested awards in each period.  The impact of adopting FAS 123(R) increased the compensation 
expense in 2006 by $57,000 before income taxes, and had less than a $0.01 impact on basic and diluted earnings 
per share.

Based on the valuation and accounting uncertainties that outstanding options presented under proposed accounting 
treatment  at  the  time,  and  the  transition  issues  associated  with  the  Company’s  new  Long  Term  Incentive  Plan 
(“LTIP”),  the  Board  of  Directors  accelerated  the  vesting  on  the  Company’s  outstanding  stock  options  during  the 
fourth quarter of 2004.  This action resulted in two financial reporting impacts.  First, the remaining fair value of all 
outstanding stock options was recognized in 2004 as part of the pro-forma footnote disclosures above.  Secondly, 
the Company recognized $146,000 of compensation expense in the fourth quarter of 2004 based on the product of 
the number of outstanding unvested options times the spread between their weighted average stock price and the 
Company stock price on October 1, 2004 times the estimated option forfeiture rate of 9.5%.  The forfeiture rate is 
based on the Company’s history over the past several years, but actual forfeiture effects in the future are measured 
and recognized in expense for any differences versus the estimate.   

Cash Flow Information 
For purposes of reporting cash flows, the Company considers cash and due from banks, interest-bearing deposits 
and any federal funds sold to be cash and cash equivalents. 

Reclassification 
Certain reclassifications have been made to the 2005 and 2004 amounts to conform to the current year presentation.  
Such reclassifications had no effect on previously reported consolidated net income or shareholders’ equity. 

New Accounting Standards 
In  July  2006,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  Interpretation  No.  48,  Accounting  for 
Uncertainty in Income Taxes, an Interpretation of FAS No. 109, Accounting for Income Taxes.  The interpretation 
defines the threshold for recognizing the financial impact of uncertain tax positions in accordance with FAS 109.   
A company is required to recognize, in its financial statements, the best estimate of the impact of a tax position only 
if  that  position  is  “more-likely-than-not”  of  being  sustained  on  audit  based  solely  on  the  technical  merits  of  the 
position on the reporting date. In evaluating whether the “more-likely-than-not” recognition threshold has been met, 
the  Interpretation  requires  the  assumption  that  the  tax  position  will  be  evaluated  during  an  audit  by  taxing 
authorities.  The  term  “more-likely-than-not”  is  defined  as  a  likelihood  of  more  than  50  percent.    Individual  tax 
positions that fail to meet the recognition threshold will generally result in either (a) a reduction in the deferred tax 
asset  or  an  increase  in  a  deferred  tax  liability  or  (b)  an  increase  in  a  liability  for  income  taxes  payable  or  the 
reduction of an income tax refund receivable. The impact may also include both (a) and (b). This Interpretation also 
provides  guidance  on  disclosure,  accrual  of  interest  and  penalties,  accounting  in  interim  periods,  and  transition.  
The Interpretation is effective for reporting periods beginning after December 15, 2006.  The Company does not 
expect  FASB  Interpretation  No.  48  to  have  a  material  impact  on  the  Company's  financial  position  or  results  of 
operations.

In  September  2006,  the  Securities  and  Exchange  Commission  (“SEC”) issued  Staff  Accounting  Bulletin  No. 108 
(“SAB  No.  108”)  to  clarify  consideration  of  the  effects  of  prior  year  errors  when  quantifying  misstatements  in 
current  year  financial  statements  for  the  purpose  of  quantifying  materiality.  SAB  No.  108  requires  issuers  to 
quantify misstatements using both the “rollover” and “iron curtain” approaches and requires an adjustment to the 
current year financial statements in the event that after the application of either approach and consideration of all 
relevant quantitative and qualitative factors, a misstatement is determined to be material. SAB No. 108 is effective 
for  fiscal  years  beginning  after  November 15, 2006. We are in the process of determining the effect, if any, that 
SAB 108 will have on our consolidated financial statements.  The Company’s analysis under SAB No. 108 of prior 
year  and  current  year  misstatements  did  not  result  in  any  adjustment  to  prior  year  or  current  year  financial 
statements. 

In  September  2006,  the  FASB  issued  FAS  No. 157,  Fair  Value  Measurements.    FAS No. 157 defines fair value, 
establishes  a  framework  for  measuring  fair  value  in  generally  accepted  accounting  standards,  and  expands 
disclosures about fair value measurements. FAS No. 157 is effective for financial statements issued for fiscal years 
beginning  after  November 15,  2007,  and  interim  periods  within  those  fiscal  years.  We  do  not  expect  that  the 
adoption of FAS No. 157 will have a material impact on our financial condition or results of operations.  

NOTE 2—ACQUISITIONS 

Acquisition of NorthStar Bancshares 
On July 5, 2006, the Company completed its acquisition of 100% of the total outstanding common stock of Kansas 
City-based  NorthStar  Bancshares,  Inc  and  its  wholly  owned  subsidiary  NorthStar  Bank  NA  (“NorthStar”)  for 
$36,000,000  in  EFSC  common  stock  (80%)  and  cash  (20%).    The  acquisition  served  to  expand  the  Company’s 
banking franchise in the greater Kansas City area.  The purchase price for the NorthStar business consisted of: 

•  $8,000,000 in cash; 
•  1,091,500 unregistered shares of EFSC common stock valued at $28,000,000 based on the average closing 
share price of EFSC common stock, as quoted on NASDAQ, for the 20 trading days ending two days prior 
to the acquisition date; 
the assumption by EFSC of a line of credit note of NorthStar, in the principal amount of $3,200,000, which 
was paid in full by EFSC on the closing date. 

• 

While the stated purchase price of NorthStar Bancshares, Inc. was $36,000,000, approximately $4,500,000 of the 
consideration is considered “contingent” and is held in an escrow account pending the collection of certain loans.  
This effectively reduced loans and other real estate owned and increased goodwill on the balance sheet by the same 
amount.    In  accordance  with  generally  accepted  accounting  principles,  approximately  177,000  shares  of  EFSC 
stock in the escrow account have not been credited to shareholders’ equity or in average shares outstanding when 
reporting fully diluted earnings per share.  All shares issued by EFSC were issued in reliance upon exemptions from 
registration set forth in Section 4(2) of the Securities Act of 1933, as amended, and Rule 506 promulgated under 
said Act.  As a result, the shares issued for the acquisition are “restricted securities” and may not be offered or sold 
in the United States absent registration or an applicable exemption from registration requirements.   

The  cash  portion  of  the  transaction  was  funded  through  internally  generated  funds  and  borrowing  on  the 
Company’s  line  of  credit.    Subsequently,  on  July  28,  2006,  the  Company  issued  $4,000,000  of  trust  preferred 
securities  (“TRUPS”)  through  a  newly  formed  affiliated  statutory  trust,  as  further  discussed  in  Note  11  – 
Subordinated Debentures in this filing.  The TRUPS proceeds were used to pay off a portion of the line of credit 
borrowing.  

At  the  time  of  the  acquisition,  on  a  consolidated  basis,  NorthStar  Bancshares,  Inc.  had  assets  of  $187,500,000, 
loans,  net  of  unearned  discount,  of  $167,200,000,  deposits  of  $158,500,000  and  stockholders’  equity  of 
$18,800,000.    The  assets  acquired  and  liabilities  assumed  were  recorded  at  their  estimated  fair  value  on  the 
acquisition date.  The fair value adjustments represent current estimates and are subject to further adjustments as the 
valuation  data  is  finalized.    Goodwill,  which  is  not  deductible  for  tax  purposes,  was  $17,800,000.    Core  deposit 
intangibles were approximately $2,400,000 and will be amortized over ten years utilizing an accelerated method.  
Core deposit intangibles are not deductible for tax purposes.  NorthStar was merged into and with Enterprise Bank 
&  Trust  on  October  6,  2006.    Please  refer  to  the  Form  8-K  filed  by  the  Company  on  July  5,  2006  for  more 
information.

Acquisition and Integration Costs 
As of the consummation date, the Company accrued certain costs associated with the acquisition.  As of December 
31,  2006,  the  accrued  balance  was  $30,000  and  is  primarily  related  to  amounts  required  to  terminate  several 
information  technology  contracts.    As  the  obligation  to  make  these  payments  was  accrued  at  the  consummation 
date, such payments will not have any impact on the consolidated statements of income.  The acquisition costs are 
reflected in Accounts payable and accrued expenses in the consolidated balance sheets.   

Through  December  31,  2006,  the  Bank  has  also  incurred  approximately  $145,000  of  integration  costs  associated 
with  the  acquisition  that  have  been  expensed  in  the  consolidated  statements  of  income.  These  costs  relate 
principally to additional costs incurred in conjunction with the information technology conversion of NorthStar.  

Reserved Credit Escrow  
As  part  of  the  acquisition  agreement,  $4,500,000  of  the  purchase  price  was  deposited  into  a  “Reserved  Credit 
Escrow” account.  These funds are being held until the Bank receives principal payments or proceeds from the sale 
of several identified loans and other real estate.   These amounts are considered “contingent consideration” under 
U.S. GAAP and therefore, were not and will not be recorded in common stock or additional paid in capital until the 
contingency is resolved.   The Reserved Credit Escrow amount was split between Loans and Other real estate.  It is 
considered to be our best estimate, or fair value, of the specific assets.  As a result, the Loans and Other real estate 
amounts in the opening balance sheet were reduced by escrow amounts. 

Acquisition of Millennium Brokerage Group 
On  October  21,  2005,  the  Company  acquired  60%  of  Millennium,  a  Tennessee  limited  liability  company.  
Millennium is a national insurance brokerage firm with headquarters in Nashville, Tennessee.  Millennium acts as a 
wholesale  distributor,  broker  and  consultant  concerning  life  insurance  products,  brokers  insurance,  and  other 
investments or financial products.  The acquisition was accounted for using the purchase method of accounting, and 
accordingly,  the  results  of  Millennium’s  operations  have  been  included  in  the  consolidated  financial  statements 
since  the  date  of  the  purchase.    The  acquisition  was  completed  through  Millennium  Holding  Company,  Inc,  a 
wholly-owned  subsidiary  of  EFSC  that  was  created  to  consummate  the  transaction.    Millennium  continues  to 
operate under their trade name.   

The  aggregate  purchase  price  was  $15,000,000  consisting  of  249,161  shares  of  EFSC  common  stock  valued  at 
$5,249,000 and $9,750,000 in cash.  Goodwill of $10,293,000, which is deductible for tax purposes, was recorded 
as  part  of  the  purchase  price  allocation.    Intangible  assets  consisting  of  customer  and  trade  name  totaling 
$4,700,000 were also recorded with a weighted average useful life of approximately 5 years. 

The terms of the agreement call for an additional 20% purchase in 2008 and 2010, respectively, for the remaining 
interests.  The consideration mix between stock and cash for subsequent payouts are at the Company’s discretion 
with  a  maximum  of  70%  stock.      Future  payouts  up  to  a  maximum  of  $36,000,000,  inclusive  of  the  initial 
$15,000,000  payout,  are  conditioned  upon  certain  pre-tax  income  performance  targets.  EFSC  is  contractually 
entitled to a priority return on its investment of 23.1% (pre-tax) before additional distributions to the Millennium 
principals.

NOTE 3—EARNINGS PER SHARE 

Basic  earnings  per  share  data  is  calculated  by  dividing  net  income  by  the  weighted  average  number  of  common 
shares outstanding during the period.  Diluted earnings per share reflects the potential dilution of earnings per share 
which could occur under the treasury stock method if contracts to issue common stock, such as stock options, were 
exercised.  The following table presents a summary of per share data and amounts for the periods indicated.

NOTE 4—SUBSEQUENT EVENTS  

Acquisition of Clayco Banc Corporation 
On  February  28,  2007,  the  Company  completed  its  acquisition  of  Kansas  City-based  Clayco  Banc  Corporation 
(“Clayco”) and its wholly owned subsidiary, Great American Bank (“Great American”) for $37 million in EFSC 
common stock (60%) and cash (40%.)   The acquisition served to expand the Company’s banking franchise in the 
greater Kansas City area.   All shares issued by EFSC were issued in reliance upon an exemption from registration 
set forth in Section 4(2) and Rule 506 of the Securities Act of 1933.  As a result, the 731,692 EFSC shares issued 
for  the  acquisition  will  be  “restricted  securities”  and  may  not  be  offered  or  sold  in  the  United  States  absent 
registration  of  an  applicable  exemption  from  registration  requirements.    The  cash  portion  of  the  transaction  was 
funded through internally generated funds and the issuance of a TRUPS, as further discussed below.   

At  the  time  of  the  acquisition,  Clayco  had  assets  of  $201,900,000,  loans,  net  of  unearned  discount,  of 
$167,000,000,  deposits  of  $150,700,000,  and  stockholders’  equity  of  $12,800,000.    The  assets  acquired  and 
liabilities assumed were recorded at their estimated fair value on the acquisition date.  The fair value adjustments 
represent  current  estimates  and  are  subject  to  further  adjustments  as  the  valuation  data  is  finalized.    Preliminary 
goodwill, which is not deductible for tax purposes, was approximately $26,300,000. Core deposit intangibles were 
approximately  $1,900,000  and  will  be  amortized  over  ten  years  utilizing  an  accelerated  method.    Core  deposit 
intangibles are not deductible for tax purposes.  Great American is expected to be merged with and into the Bank in 
2008.  Please refer to the Form 8-K’s filed by the Company on November 22, 2006 and March 1, 2007 for more 
information.

Trust Preferred Securities - EFSC Capital Trust VI 
On February 26, 2007, EFSC Statutory Capital Trust VI (“EFSC Trust VI”), a newly formed Delaware statutory 
trust and subsidiary of EFSC, issued 14,000 floating rate Trust Preferred Securities at $1,000 per share to a Trust 
Preferred Securities Pool.   The fixed rate is equal to 6.573% until March 2012 when the rate floats at three-month 
London  Interbank  Offered  Rate  (“LIBOR”)  +  1.60%,  and  is  payable  quarterly  beginning  March  30,  2007.    The 
TRUPS  are  fully,  irrevocably  and  unconditionally  guaranteed  on  a  subordinated  basis  by  the  Company.  The 
proceeds were invested in junior subordinated debentures of the Company.  The net proceeds to the Company from 
the sale of the junior subordinated debentures, were approximately $14,000,000.   The TRUPS mature on March 
30, 2037.  The mandatory date may be shortened to a date not earlier than March 30, 2012 if certain conditions are 
met.  The TRUPS are classified as subordinated debentures and the distributions are recorded as interest expense in 
the  Company’s  consolidated  financial  statements.    The  proceeds  from  the  offering  were  used  to  fund  the  cash 
portion of the acquisition of Clayco, as discussed above.

During 2006, the Company did not sell any investments in debt and equity securities.  During 2005, proceeds from 
sales of investments in debt and equity securities were $39,040,000, which resulted in gross gains of $12,000 and 
gross  losses  of  $506,000.    During  2004,  proceeds  from  sales  of  investments  in  debt  and  equity  securities  were 
$62,766,000,  which  resulted  in  gross  gains  of  $131,000  and  gross  losses  of  $4,000.    Debt  and  equity  securities 
having  a  carrying  value  of  $32,084,000  and  $18,365,000  at  December 31,  2006  and  2005,  respectively,  were 
pledged as collateral to secure public deposits and for other purposes as required by law or contract provisions. 

As  a  member  of  the  Federal  Home  Loan  Bank  (“FHLB”)  system  administered  by  the  Federal  Housing  Finance 
Board,  the  Bank  is  required  to  maintain  a  minimum  investment  in  the  capital  stock  of  its  respective  FHLB 
consisting  of  membership  stock  and  activity-based  stock.  At  December  31,  2006,  the  membership  stock 
requirement for the Bank was 0.12% of its total assets subject to a maximum of $10 million.   The activity-based 
stock requirement is 4.45% of the Bank’s aggregate outstanding FHLB advances.  The FHLB stock is recorded at 
cost, which represents redemption value.  The Bank is a member of the FHLB of Des Moines. 

Provided below is a summary of securities available for-sale which were in an unrealized loss position at December 
31, 2006 and 2005.  The unrealized losses reported as of December 31, 2006 for obligations of U.S. government 
agencies for 12 months or more includes 32 FNMA agency notes with estimated maturities or repricings of one to 
two  years.    The  unrealized  loss  reported  for  the  mortgage-backed  securities  for  12  months  or  more  includes  26 
securities  and  primarily  relates  to  Fannie  Mae  (“FNMA”)  or  Freddie  Mac  (“FHLMC”)  pools  with  estimated 
maturities or repricings of one to four years.  Fannie Mae or Freddie Mac guarantees the contractual cash flows of 
these securities.  The unrealized losses reported for municipal bonds for 12 months or more includes 5 securities.   
The  Company  has  the  ability  and  intent  to  hold  these  securities  until  such  time  as  the  value  recovers  or  the 
securities  mature.    Further,  the  Company  believes  the  deterioration  in  value  is  attributable  to  changes  in  market 
interest rates and not credit quality of the issuer.

The  Bank  grants  commercial,  residential,  and  consumer  loans  primarily  in  the  St.  Louis  and  Kansas  City 
metropolitan areas.  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 is concentrated in and secured by real estate.  
The ability of the Company’s borrowers to honor their contractual obligations is dependent upon the local economy 
and its effect on the real estate market. 

Following  is  a  summary  of  activity  for  the  year  ended  December 31,  2006  of  loans  to  executive  officers  and 
directors or to entities in which such individuals had beneficial interests as a shareholder, officer, or director.  Such 
loans  were  made  in  the  normal  course  of  business  on  substantially  the  same  terms,  including  interest  rates  and 
collateral, as those prevailing at the time for comparable transactions with other customers and did not involve more 
than the normal risk of collectibility.

The Bank had one loan over 90 days past due and still accruing interest at December 2006.  This loan paid off on 
January 5, 2007.  There were no loans over 90 days past due and still accruing interest at December 31, 2005 and 
2004.  If interest on non-accrual loans had been accrued, such income would have been $218,000, $144,000, and 
$103,000 for the years ended December 31, 2006, 2005, and 2004, respectively.  The cash amount recognized as 
interest income on non-accrual loans was $75,000, $109,000, and $64,000 for the years ended December 31, 2006, 
2005, and 2004, respectively.  The amount recognized as interest income on impaired loans continuing to accrue 
interest was $3,000, $0, and $0 for the years ended December 31, 2006, 2005, and 2004, respectively. 

NOTE 7—DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES 

The  Bank  utilizes  interest  rate  swap  derivatives  as  one  method  to  manage  some  of  its  interest  rate  risks  from 
recorded financial assets and liabilities. These derivatives are utilized when they can be demonstrated to effectively 
hedge a designated asset or liability and such asset or liability exposes the Bank to interest rate risk.  The decision 
to  enter  into  an  interest  rate  swap  is  made  after  considering  the  asset/liability  mix  of  the  Bank,  the  desired 
asset/liability sensitivity and by interest rate levels.  Prior to entering into a hedge transaction, the Bank formally 
documents  the  relationship  between  hedging  instruments  and  hedged  items,  as  well  as  the  risk  management 
objective for undertaking the various hedge transactions. 

The  Bank  accounts  for  its  derivatives  under  SFAS  No.  149,  An  Amendment  of  Statement  133  on  Derivative 
Instruments  and  Hedging  Activities  and  SFAS  No.  133,  Accounting  for  Derivative  Instruments  and  Hedging 
Activities.  These Standards require recognition of all derivatives as either assets or liabilities in the balance sheet 
and  require  measurement  of  those  instruments  at  fair  value  through  adjustments  to  the  hedged  item,  other 
comprehensive income, or current earnings, as appropriate. 

Cash Flow Hedges 
Previously, the Bank entered into interest rate swaps to convert floating-rate loan assets to fixed rates.   Interest rate 
swaps  with  notional  amounts  of  $30,000,000  and  $40,000,000  under  which  the  Bank  received  a  fixed  rate  of 
5.3425% and 5.4150% matured in March and April 2006, respectively.   As of December 31, 2006, the Bank had 
no outstanding cash flow hedges. 

The swap agreements provided for the Bank to pay a variable rate of interest equivalent to the prime rate and to 
receive a fixed rate of interest.  Amounts paid or received under these swap agreements were accounted for on an 
accrual basis and recognized as interest income of the related asset.  The net cash flows related to cash flow hedges 
decreased  interest  income  on  loans  by  $410,000  and  $539,000  in  2006  and  2005,  respectively,  and  increased 
interest income on loans by $1,163,000 in 2004.   

Cash flow hedges are accounted for at fair value.   The effective portion of the change in the cash flow hedge’s gain 
or  loss  is  reported  as  a  component  of  other  comprehensive  income,  net  of  taxes.    The  ineffective  portion  of  the 
change  in  the  cash  flow  hedge’s  gain  or  loss  is  recorded  in  earnings  on  each  quarterly  measurement  date.    At 
December  31,  2006  and  2005,  $0  and  $263,000,  respectively,  in  deferred  losses,  net  of  tax,  related  to  cash  flow

hedges were recorded in accumulated other comprehensive income.  All cash flow hedges were effective; therefore, 
no gain or loss was recorded in earnings in 2006, 2005 and 2004.   

Fair Value Hedges 
The Bank has entered into interest rate swap agreements with the objective of converting the fixed interest rate on 
certain brokered CDs to a variable interest rate.  The swap agreements provide for the Bank to pay a variable rate of 
interest based on a spread to the one or three-month LIBOR and to receive a fixed rate of interest equal to that of 
the brokered CD (hedged instrument.)   Fair value hedges are accounted for at fair value.   All changes in fair value 
are measured on a quarterly basis.   

Amounts  to  be  paid  or  received  are  accounted  for  on  an  accrual  basis  and  recognized  as  interest  expense  of  the 
related  liability.      The  net  cash  flows  related  to  fair  value  hedges  increased  interest  expense  on  certificates  of 
deposit by $363,000 and $360,000 in 2006 and 2005, respectively, and decreased interest expense by $346,000 in 
2004.  Two swaps, each with a $10,000,000 notional amount, under which the Bank received a fixed rate of 2.30% 
and  2.45%  matured  in  February  and  April  2006,  respectively.    At  December  31,  2006,  the  Bank  had  one 
outstanding fair value hedge.   

At inception of the CD, the Company paid broker placement fees by reducing the proceeds received from the issued 
CD.  The  fees  did  not  affect  the  inception  value  of  the  interest  rate  swap.    Placement  fees  are  capitalized  and 
amortized into interest expense over the life of the CD in a manner similar to debt issuance costs.  

Non-Designated Hedges 
The Bank has entered into interest rate swap agreements with the objective of converting long-term fixed rates on 
certain loans to a variable interest rate.  The swap agreements provide for the Bank to pay a fixed rate of interest 
equal to that of the loan and to receive a variable rate of interest based on a spread to one-month LIBOR.  The non-
designated hedges are accounted for at fair value.   All changes in fair value are measured on a quarterly basis.   

Under  the  swap  agreements  the  Bank  is  to  pay  or  receive  interest  monthly.    The  net  cash  flows  related  to  these 
hedges decreased interest income on loans by $2,100 in 2006.  One swap agreement is a forward rate lock hedging 
against rate increases through August 2007.  As a result, the cash flows for this swap will not begin until August 
2007.

The notional amounts of derivative financial instruments do not represent amounts exchanged by the parties, and 
therefore, are not a measure of the Bank’s credit exposure through its use of these instruments.  The credit exposure 
represents  the  accounting  loss  the Bank would incur in the  event the counterparties failed completely to perform

according to the terms of the derivative financial instruments and the collateral held to support the credit exposure 
was of no value.  Given the fair value loss associated with the derivatives at December 31, 2006, the Bank had no 
credit  exposure  to  counterparties.    At  December  31,  2006  and  2005,  in  connection  with  our  interest  rate  swap 
agreements we had pledged investment securities available for sale with a fair value of $2,500,000.  At December 
31,  2006  and  2005,  we  had  accepted,  as  collateral  in  connection  with  our  interest  rate  swap  agreements,  cash  of 
$196,000.

The subordinated debentures, which are the sole assets of the trust, 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.  The trust preferred securities 
are included in Tier 1 capital for regulatory capital purposes, subject to certain limitations. 

The 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 accrual of interest to be paid on the subordinated debentures 
held by the trusts is recorded as interest expense in the Company’s consolidated financial statements.

Except as noted below, various legal claims have arisen during the normal course of business which, in the opinion 
of management, after discussion with legal counsel, will not result in any material liability.  

In accordance with SFAS No. 5, Accounting for Contingencies, during 2003 the Company recognized $725,000 in 
expense  related  to  a  settlement  of  a  dispute  with  another  financial  institution  pursuant to an agreement signed in 
February of 2003.  An additional $575,000 was paid on this settlement in 2004.

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  as  of  December  31,  2006  or 
December  31,  2005.    Management  believes  it  is  more  likely  than  not  that  the  results  of  future  operations  will 
generate sufficient taxable income to realize the deferred tax assets above. 

NOTE 16—REGULATORY MATTERS 

The Company and 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 Bank’s financial 
statements.    Under  capital  adequacy  guidelines  and  the  regulatory  framework  for  prompt  corrective  action,  the 
Company  and  Bank  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  Bank’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  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.  Management believes, as of December 31, 2006 and 2005, that the 
Company and Bank meet all capital adequacy requirements to which they are subject. 

As  of  December  31,  2006  and  2005,  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, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table.

NOTE 17—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 
appreciation  rights,  and  restricted  share  units  (RSU’s),  as  designated  by  the  Company’s  Board  of  Directors.  The 
Company  uses  authorized  and  unissued  shares  to  satisfy  share  award  exercises.      During  2006,  share-based 
compensation was issued in the form of stock, stock options and RSU’s.  At December 31, 2006, 892,865 shares 
were available for grant under the various share-based compensation plans.  An additional 96,619 shares of stock 
were available for issuance under the Stock Plan for Non-Management Directors approved by the Shareholders in 
April 2006.  Share-based compensation has been settled with newly issued shares. 

The share-based compensation expense that was charged against income was $1,252,000, $690,000 and $228,000 
for the years ended December 31, 2006, 2005 and 2004, respectively. The total income tax benefit recognized in the 
income statement for share-based compensation arrangements was $525,000, $831,000 and $11,000 for the years 
ended December 31, 2006, 2005 and 2004, respectively.   

In determining compensation cost for stock options, the Black-Scholes option-pricing model is used to estimate the 
fair value of options on date of grant. The Black-Scholes model is a closed-end model that uses the assumptions in 
the following table. The risk-free rate for the expected term is based on the U.S. Treasury zero-coupon spot rates in 
effect  at  the  time  of  grant.    Expected  volatility  is  based  on  historical  volatility  of  the  Company’s  stock.  The 
Company  uses  historical  exercise  behavior  and  other  factors  to  estimate  the  expected  term  of  the  options,  which 
represents the period of time that the options granted are expected to be outstanding.

Employee Stock Options 
Stock options were granted to key employees with exercise prices equal to the market price of the Company’s stock 
at the date of grant and have 10-year contractual terms. Stock options have a vesting schedule of between three to 
five years.   The weighted average grant date fair value of options granted during 2006, 2005 and 2004 was $18.34, 
$11.62,  and  $7.80,  respectively.    Compensation  expense  related  to  stock  options  was  $21,000,  $15,000,  and 
$146,000 in 2006, 2005, and 2004, respectively.  Compensation expense in 2004 was related to the acceleration of 
outstanding  employee  stock  options  as  described  in  Note  1  –  Significant  Accounting  Policies.      On  a  quarterly 
basis, actual forfeitures are measured and recognized in expense for any differences versus the estimate.  In 2006, 
the difference between actual and estimated forfeitures on the accelerated options decreased compensation expense 
by $36,000.  In 2005, the difference between actual and estimated forfeitures on the accelerated options increased 
compensation  expense  by  $15,000.  The  total  intrinsic  value  of  options  exercised  on  the  date  of  exercise  was 
$1,750,000, $4,200,000, and $1,135,000 in 2006, 2005 and 2004, respectively.  Cash received from the exercise of 
stock  options  in  2006  was  $1,226,000.    At  December  31,  2006,  there  was  $189,500  of  total  unrecognized 
compensation cost related to stock options, which is expected to be recognized over a weighted average period of 
2.7 years.   Following is a summary of the employee stock option activity for 2006.

Restricted Share Units 
In 2005, the Company began awarding nonvested stock, in the form of RSU’s, as part of a new long-term incentive 
plan.  RSU’s awarded to employees are subject to continued employment and vest ratably over five years.  RSU’s 
granted  to  directors  in  2005  vested  on  December  31,  2005.    RSU’s  do  not  carry  voting  or  dividend  rights  until 
vesting.  Sales of the units are restricted prior to vesting.   Compensation expense related to employee RSU’s was 
$1,029,000 and $483,000 in 2006 and 2005, respectively.  In 2005, Other noninterest expense included $117,000 
for the RSU’s awarded to the directors of the Company.  The total fair value (at vest date) of shares vested during 
2006 and 2005 was $1,506,000 and $658,000, respectively.  At December 31, 2006, there was $3,418,000 of total 
unrecognized compensation cost related to nonvested RSU’s, which is expected to be recognized over a weighted 
average  period  of  3.5  years.      A  summary  of  the  status  of  the  Company's  restricted  share  unit  awards  as  of 
December 31, 2006 and changes during the year then ended is presented below.

Stock Appreciation Rights 
On  April  1,  1999,  the  Company  adopted  a  Stock  Appreciation  Rights  (“SAR’s”)  Plan.    This  Plan  replaced  the 
previous  form  of  cash  compensation  for  directors  of the Company and its subsidiaries.  Awards vest based upon 
attendance and unit performance.  Under the plan, the Company has the option to pay vested SAR’s either in the 
form of cash or Company common stock.  There were no SAR’s granted in 2006, 2005 or 2004.  For the year ended 
December 31, 2006 and 2005, the Company recognized $60,000 and $41,000 of expense to record the fair value of 
the SAR’s.   The Company recognized a reduction to expense of $6,000 to record the fair value of the SAR’s for 
the year ended December 31, 2004.  During 2006, the Company paid cash of $19,000 for SAR’s that vested in July 
and October.  In January 2007, the Company paid $118,000 to settle SAR’s that vested on December 31, 2006.  At 
December 31, 2006, there were no other SAR’s outstanding.     

Stock Plan for Non-Management Directors 
In 2006, the Company adopted a Stock Plan for Non-Management Directors, which provides for issuing shares of 
common stock to non-employee directors as compensation in lieu of cash.  Shares granted under this plan may be 
subject  to  resale  restrictions  (“restricted  stock”).      The  plan  was  approved  by  the  shareholders  and  allows  up  to 
100,000 shares to be awarded.   In July 2006, the Company issued 3,381 shares of restricted stock at a fair value of 
$25.45  per  share.    For  the  year  ended  December  31,  2006,  the  Company  recognized  $125,000  of  stock-based 
compensation expense for the directors.  At December 31, 2006, there is no unrecognized compensation cost related 
to this plan.    

Moneta Plan 
In  1997,  the  Company  entered  into  a  solicitation  and  referral  agreement  with  Moneta  Group,  Inc.  (“Moneta”),  a 
nationally recognized firm in the financial planning industry.  The Company renegotiated the original agreement in 
2003.  Under the agreements, Moneta received options for banking business referrals and still receives a portion of 
the gross margin earned by Trust in the form of cash.  As a result, there have been no options granted to Moneta 
since 2003.  The fair value of each Moneta option grant was estimated on the date of grant using the Black-Scholes 
option pricing model.  The Company recognized the fair value of the options over the vesting period as expense.  
The Company recognized $17,000, $34,000, and $88,000 in Moneta option-related expenses during 2006, 2005 and 
2004, respectively.  As of December 31, 2006, the fair value of all Moneta options had been recognized, therefore, 
there is no unrecognized compensation cost.

401(k) plans  
Effective  January 1,  1993,  the  Company  adopted  a  401(k)  thrift  plan  which  covers  substantially  all  full-time 
employees  of  the  Bank  over  the  age  of  21.    In  addition,  substantially  all  employees  of  Millennium  can  elect  to 
participate  in  a  safe-harbor  401(k)  plan.    The  amount  charged  to  expense  for  the  Company’s  contributions, 
including Millennium, to the plans was $323,000, $843,000, and $476,000 for 2006, 2005, and 2004, respectively.  

NOTE 18—DISCLOSURES ABOUT FINANCIAL INSTRUMENTS 

The Bank issues financial instruments with off balance sheet risk 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 represented by the contractual amount of these instruments.  The Bank uses the same credit policies in 
making commitments and conditional obligations as it does for financial instruments included on its consolidated 
balance sheets.  At December 31, 2006, no amounts have been accrued for any estimated losses for these financial 
instruments. 

The contractual amount of off-balance-sheet financial instruments as of December 31, 2006 and 2005 is as follows:

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 and may 
require  payment  of  a  fee.    Of  the  total  commitments  to  extend  credit  at  December 31,  2006  and  2005, 
approximately $35,900,000 and $10,500,000, respectively, represents fixed rate loan commitments.  Since certain 
of  the  commitments  may  expire  without  being  drawn  upon,  the  total  commitment  amounts  do  not  necessarily 
represent future cash requirements.  The Bank evaluates each customer’s credit worthiness on a case-by-case basis.  
The  amount  of  collateral  obtained,  if  deemed  necessary  by  the  Bank  upon  extension  of  credit,  is  based  on 
management’s  credit  evaluation  of  the  borrower.    Collateral  held  varies,  but  may  include  accounts  receivable, 
inventory, premises and equipment, and real estate. 

Standby  letters  of  credit  are  conditional  commitments  issued  by  the  Bank  to  guarantee  the  performance  of  a 
customer to a third party.  These standby letters of credit are issued to support contractual obligations of the Bank’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 standby letters of credit range from 1 month to 5 
years at December 31, 2006. 

In 2006, the Company entered into a commitment to invest in a private equity bank fund.  The commitment will be 
drawn down in the next 18 months.   

SFAS 107, Disclosures about Fair Value of Financial Instruments, extends existing fair value disclosure for some 
financial  instruments  by  requiring  disclosure  of  the  fair  value  of  such  financial  instruments,  both  assets  and 
liabilities recognized and not recognized in the consolidated balance sheets. 

Following  is  a  summary  of  the  carrying  amounts  and  fair  values  of  the  Company’s  financial  instruments  on  the 
consolidated balance sheets at December 31, 2006 and 2005:

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, Fed 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. 

Investments in Debt and Equity Securities 
Fair values are based on quoted market prices or dealer quotes. 

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. 

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. 

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.    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. 

Subordinated Debentures 
Fair value of floating interest rate subordinated debentures is assumed to equal carrying value.  Fair value of fixed 
interest rate subordinated debentures is based on market prices. 

Other Borrowed Funds 
Other  borrowed  funds  include  FHLB  advances,  customer  repurchase  agreements,  federal  funds  purchased,  and 
notes payable.  The fair value of 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. 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. 

Commitments to Extend Credit and Standby Letters of Credit 
The fair value of commitments to extend credit and standby 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.  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  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.  Because no market 
exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments 
regarding  future  expected  loss  experience,  current  economic  conditions,  risk  characteristics  of  various  financial 
instruments,  and  other  factors.    These  estimates  are  subjective  in  nature  and  involve  uncertainties  and  matters  of 
significant  judgment,  and  therefore,  cannot  be  determined  with  precision.    Changes  in  assumptions  could 
significantly  affect  the  estimates.  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 19—SEGMENT REPORTING 

Management segregates the Company into three distinct businesses for evaluation purposes.  The three segments 
are  Banking,  Wealth  Management,  and  Corporate  and  Intercompany.    The  segments  are  evaluated  separately  on 
their individual performance, as well as, their contribution to the Company as a whole. 

The  majority  of  the  Company’s  assets  and  income  result  from  the  Banking  segment.    The  Bank  is  a  full-service 
commercial bank with four St. Louis locations and six locations in the Kansas City region.   

The  Wealth  Management  segment  includes  the  Trust  division  of  the  Bank  along  with  Millennium.    The  Trust 
division  of  the  Bank  provides  estate  planning,  investment  management,  and  retirement  planning  as  well  as, 
consulting  on  management  compensation,  strategic  planning  and  management  succession  issues.    Millennium 
operates  life  insurance  advisory  and  brokerage  operations  from  thirteen  offices  serving  life  agents,  banks,  CPA 
firms, property & casualty groups, and financial advisors in 49 states.   

The  Corporate  and  Intercompany  segment  includes  the  holding  company  and  subordinated  debentures.    The 
Company  incurs  general  corporate  expenses  and  owns  Enterprise  Bank  &  Trust  and  a  controlling  ownership  of 
Millennium.   

The financial information for each business segment reflects that information which is specifically identifiable or 
which is allocated based on an internal allocation method.
