To Our Shareholders

As I often do when I write this yearly letter, I ask
myself, “Who is this for? Why do I write it? Does 
anyone other than our competitors and the investment
bankers calling on us read this?” Then I remind myself 

it is a letter to my partners 
— to those I serve — our 
shareholders, my colleagues, 
our clients, our prospective
clients, the communities we 
serve, and the regulators who 
are charged with overseeing 
our activities. My purpose is
to explain what happened this 
year, to discuss our success and 
our challenges. But, I can’t 
make any “forward looking 
statements,” the lawyers tell 
me, because someone might 

rely too heavily on them, and, if they don’t come true, 
I (we) could be liable for misleading someone. That
presupposes that this is an exact science and that every
CEO knows exactly what is going to happen in the 
future and he or she is 100% sure of it and is correct. 
Well, not this one! I do not know what the Federal 
Reserve is going to do about interest rates. I do not 
know how things will develop in the Middle East, 
India, China, the rest of Asia or in the rest of the world
for that matter and what impact unforeseen events 
might have on us. Will the consumer keep buying? 
Will housing continue to slow and prices begin to 
drop? Will oil and gas prices rise or fall? Will there be
layoffs? Will the Congress or state legislators spend 
more, increase taxes, add new burdensome regulation, 
or reduce the incentives to invest that have driven 
this strong economy of ours for so long? Although I 
don’t know the answers, I do try to determine their 
probabilities and, with my colleagues, build a plan that
provides us with long-term opportunities taking those 
probabilities into account. Our 2010 strategic plan, 
Vision 2010, is meant to do just that. 

In short, 2006 was a good year. We earned $39.30 
million, a 16.43 percent increase over 2005. Earnings 
per share were $1.72, up 17.81 percent over the prior 
year. This resulted in a return on average equity of 
10.98 percent and a return on average assets of 1.11 
percent for 2006 — a respectable performance, but not 
great. Credit improvement and recoveries, mortgage
servicing asset sales, and hard sales work in all areas 
drove the results on the upside. Tight margins with 
very competitive pricing of both loans and deposits, 
and increasing costs from investment in long-term 
infrastructure and in new facilities, people and markets 
impeded better performance. All in all, I am pleased 
with the results but not satisfi ed. See the Management 
Discussion and Analysis in our 2006 Form 10-K for a 
more detailed review of the year.

During 2005 and early 2006, we continued to work on
our strategic Vision 2010 Plan. We started by reviewing 
our history, and discussing our culture and the values 
which make us distinctive. These are at the core of our 
brand and our value proposition. While you can state 
your values, if they are not evident and demonstrable
in your history they are just puff. We reviewed and
recommitted to our values: integrity; superior quality in 
everything we do; outstanding client service; the ideals 
of teamwork; and community leadership. 

From these values, we honed our Mission Statement 
for more clarity. The Mission answers the question of 
why we are in business and what our defi ning purpose
is: To help individuals, institutions, businesses and 
communities achieve security, build wealth and realize
their dreams. 

If we deliver on this Mission, we will achieve the
Vision we have for the future. It is to always offer our 
clients the highest quality service; to support a proud 
family of colleagues who personify the 1st Source 
spirit of partnership; to be the fi nancial institution
of choice in each market we serve; to remain 
independent and nurture pride of ownership among 
our 1st Source colleagues; and to achieve superior 
long-term fi nancial results.

Full services in all markets
We decided we had been too timid in our expansion 
growth efforts and needed to step up our energy in 
hiring staff and developing faster. Rather than just focus 
on retail in Fort Wayne, we added private banking, 
agricultural capabilities, small business banking, wealth 
management services, and business banking to our 
service offering. We then launched an aggressive media/
marketing campaign, and topped it off by celebrating the
opening of a new regional headquarters for 1st Source 
in downtown Fort Wayne. Our name and logo are now 
proudly displayed on 1st Source Center inviting the 
community to experience what straight talk and sound 
advice is all about. 

Duke Jones, President, and Chris Murphy, Chairman, in our 
new Fort Wayne regional headquarters, 1st Source Center.

We are committed as a team to make Vision 2010 a 
reality. To do so we have created six pillars within a 
“proverbial” 1st Source house (see page vi). These are 
the key initiatives we are undertaking to achieve our 
long term Vision. The pillars (or initiatives) stabilize 
the house by providing the resources, facilities, people, 
capacities, and capabilities necessary to do so. 

Develop our people
The most important initiative for achieving long-
term consistent success is “Develop Our People.” 
During the year, we were selected as one of the “Best
Places to Work in Indiana” by the Indiana Chamber 
of Commerce. This honor occurred because we have 
a great group of colleagues who like being in service 
to each other and to our clients. Our colleagues truly 
care and we strive to ensure they have the training 
necessary to exceed our clients’ expectations and wow 
our clients with service. We are trying to build an even 
more responsive and proactive culture through staff 
training, goal setting, results reporting, and holding each 
other accountable for achieving set and agreed upon 
goals. We looked to the future and conducted a strong 
recruiting program which attracted a talented group 
of professionals with new capabilities, team building 
capacity, and future leadership potential. 

Vitalize sales
Growth comes from attracting new clients and
doing more for those we have. First, our clients
want more convenience, so we opened new facilities
with a different approach to transaction services. 
We opened newly designed banking centers in 
Dowagiac, and Northpointe and Heritage Square 
Martin’s Supermarkets to give better service and more 
convenience to our present client base. We focused 
on helping small business clients achieve their dreams 
and became the #1 SBA lender in Northern Indiana 
and Southwestern Michigan in 2006. A pilot program
of retail bankers mentored by small business bankers 
became “microlenders” — serving the “Mom and 
Pop” transactional level of small business client needs. 
Throughout the bank, we directed the process of 
selling and personal sales, developing responsive and 
knowledgeable employees who have the talent to 
discern needs and to solve problems for clients.

As we go to press, 1st Source Corporation and FINA 
Bancorp, Inc. jointly announced that they have entered 
into a defi nitive merger agreement in which 1st Source 
will acquire FINA in exchange for cash and stock. 
FINA, headquartered in Valparaiso, Indiana, operates 
First National Bank, Valparaiso, a full service bank with 
approximately $600.0 million in assets, 26 banking 
facilities located in Porter, LaPorte and Starke County, 
Indiana, and a full complement of personal and business 
banking, as well as trust and asset management services.  

First National Bank, Valparaiso is located in the fastest 
growing area of the 1st Source Bank retail footprint. It 
provides a natural extension of 1st Source’s presence in 
the Valparaiso market, not only in terms of geographic 
coverage, but also in terms of the products and services 
both banks offer and, most importantly, in terms of the 
dedication of the employees of both banks to delivering 

exceptional, personalized service to our customers. The
history, values, and mission of both organizations are
very much aligned.

Open new markets
To gain new clients, we opened a facility in Kalamazoo 
and committed some of our most experienced 
colleagues to developing this market giving us access
to a whole new region to serve. In October 2006, we
“hit the pavement” running in Kalamazoo. We have also 
hired leadership for our efforts in Lafayette, Indiana, 
which will open in 2007. We have identifi ed our fi rst
location and are moving fast to reconfi gure, occupy and
open it. Additionally, we conducted signifi cant analysis 
on markets across the country that offer opportunities 
for 1st Source and will develop entry strategies for 
these over the next few years.

Implement Cornerstone
None of this can be done 
without the proper infrastructure. 
“Cornerstone” is the euphemism 
we use for acquiring and installing 
new information processing and 
management systems which will 
serve as our scalable platform 
for the next 10 to 15 years 
allowing us to grow and expand. 
Cornerstone will also consolidate 
and simplify processes, allowing 
us to obtain best in class service 
performance and signifi cant 
productivity improvements. This is 
a long-term project. Cornerstone 
has been going on for over a year 
and has used enormous resources, 
both human and fi nancial. Successful conversion is 
critical to our future and installation is planned to 
begin in mid-2007. As a result, 2007 will be a challenge 
for all of us. It will take a few years to truly take
advantage of these new systems but we look forward to
having a more robust platform on which to build.

Superior fi nancial results 
Lastly, to grow, to invest in people and facilities, and 
to constantly anticipate and meet the needs of our 
clients in all kinds of fi nancial markets we need to have
“Superior Financial Results.” We want to maintain and 
even improve on a fortress balance sheet with strong 
performance in credit quality, operating cost control, 
margin and risk management, and long-term returns. 
We need to reduce volatility and have reduced the 
size of the mortgage servicing asset by selling down 
that portfolio substantially this past year. We must have 
excellent credit quality and have continued to improve 
credit training, professionalize collection and recovery
work and separate underwriting from selling and 
serving clients. When we are disciplined about credit 
and collections, our credit clients perform better and
are more successful and our deposit clients are more 
protected.  It truly is a win-win situation.

Conclusion
There are real challenges to our success. Margins are 
tougher as competition buys business with lower loan 
pricing, liberal policies on the credit side and higher

pricing on deposits. And there are always new products 
and more convenience. Our colleagues are feeling the
stress of the conversion of our systems, the fl ow of new
initiatives, and the constant pressure of competition. 
Having said that, we are committed to our clients and 
to making 1st Source #1 in everything we do and 
everywhere we go. This has been so since 1863 and 
each of my colleagues knows he or she is adding to the 
legacy passed on to us by those who came before.

This year we are losing the services of a fi ne director 
who has fi lled his term limits. David Bowers, former 
Chief Financial Offi cer of 1st Source and retired Chief 
Financial Offi cer of Park National Bank in Newark, 
Ohio, served most recently as Chairman of the Audit 
Committee. His experience, his knowledge, and his 
counsel have been welcomed additions to the Board
and to me in particular. He asked probing and insightful 
questions and was always focused on the risk-reward 
trade-off and the impact of decisions on the bottom 
line. Dave will be missed. 

Thank you for your support this past year, we look

forward to the challenges ahead knowing that 2007 is a 

platform year for the future.

of three to seven years.

2006 Form 10-K

1st SOURCE INSURANCE, INC.

t

1st Source Insurance, Inc. is a wholly owned subsidiary of 1st Source Bank that provides insurance services to individuals and businesses covering corporate and 
personal property products, casualty insurance products, and individual and group health and life insurance products. 

1st SOURCE CORPORATION INVESTMENT ADVISORS, INC.

t

1st Source Corporation Investment Advisors, Inc. is a wholly owned subsidiary of 1st Source Bank that provides investment advisory services to trust and investment 
clients of 1st Source Bank and to the 1st Source Monogram Funds. 1st Source Corporation Investment Advisors, Inc. is registered as an investment advisor with the 
Securities and Exchange Commission under the Investment Advisors Act of 1940. 1st Source Corporation Investment Advisors, Inc. serves strictly in an advisory 
capacity and, as such, does not hold any client securities.  

OTHER CONSOLIDATED SUBSIDIARIES

We have various other subsidiaries that are not significant to the consolidated entity.

1st SOURCE CAPITAL TRUST II, III, AND IV

t

Our unconsolidated subsidiaries include, 1st Source Capital Trust II, III, and IV (1st Source Capital Trust I was dissolved on May 26, 2005). These subsidiaries 
were created for the purposes of issuing $17.25 million, $10.00 million, and $30.00 million of trust preferred securities, respectively, and lending the proceeds 
to 1st Source. We guarantee, on a limited basis, payments of distributions on the trust preferred securities and payments on redemption of the trust preferred 
securities. 

COMPETITION

The activities in which we and the Bank engage are highly competitive. These activities and the geographic markets served involve competition with other banks, 
some of which are affiliated with large bank holding companies headquartered outside of our principal market. We generally compete on the basis of client service 
and responsiveness to client needs, available loan and deposit products, the rates of interest charged on loans and leases, the rates of interest paid for funds, other 
credit and service charges, the quality of services rendered, the convenience of banking facilities, and in the case of loans and leases to large commercial borrowers, 
relative lending limits.

In addition to competing with other banks within our primary service areas, the Bank also competes with other financial service companies, such as credit unions, 
industrial loan associations, securities firms, insurance companies, small loan companies, finance companies, mortgage companies, real estate investment trusts, 
certain governmental agencies, credit organizations, and other enterprises. Additional competition for depositors’ funds comes from United States Government 
securities, private issuers of debt obligations, and suppliers of other investment alternatives for depositors. Many of our non-bank competitors are not subject to 
the same extensive Federal regulations that govern bank holding companies and banks. Such non-bank competitors may, as a result, have certain advantages over 
us in providing some services.

We compete against these financial institutions by offering a full array of products and highly personalized services. We also rely on our history in our core market 
dating back to 1863, as well as, relationships that our long-term colleagues have with our clients, and the capacity we have for quick local decision-making.

EMPLOYEES

At December 31, 2006, we had approximately 1,200 employees on a full-time equivalent basis. We provide a wide range of employee benefits and consider 
employee relations to be good.

REGULATION AND SUPERVISION

General — 1st Source and the Bank are extensively regulated under Federal and State law. To the extent that the following information 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 our business and our prospective business. Our operations may be affected by legislative changes and by the policies of various regulatory 
authorities. We are unable to predict the nature or the extent of the effects on our business and earnings that fiscal or monetary policies, economic controls, or new 
Federal or State legislation may have in the future.

We are a registered bank holding company under the Bank Holding Company Act of 1956 (BHCA) and, as such, we are subject to regulation, supervision, and 
examination by the Board of Governors of the Federal Reserve System (Federal Reserve). We are required to file annual reports with the Federal Reserve and to 
provide the Federal Reserve such additional information as it may require.

The Bank, as an Indiana state bank and member of the Federal Reserve System, is supervised by the Indiana Department of Financial Institutions (DFI) and the
Federal Reserve. As such, the Bank is regularly examined by and subject to regulations promulgated by the DFI and the Federal Reserve. Because the Federal 
Deposit Insurance Corporation (FDIC) provides deposit insurance to the Bank, the Bank is also subject to supervision and regulation by the FDIC (even though the 
FDIC is not its primary Federal regulator).

Bank Holding Company Act — Under the BHCA, as amended, our activities are limited to business so closely related to banking, managing, or controlling banks as 
to be a proper incident thereto. We are also subject to capital requirements applied on a consolidated basis in a form substantially similar to those required of the 
Bank. The BHCA also requires a bank holding company to obtain approval from the Federal Reserve before (i) acquiring, or holding more than 5% voting interest 
in any bank or bank holding company, (ii) acquiring all or substantially all of the assets of another bank or bank holding company, or (iii) merging or consolidating 
with another bank holding company.

The BHCA also restricts non-bank activities to those which, by statute or by Federal Reserve regulation or order, have been identified as activities closely related to 
the business of banking or of managing or controlling banks. As discussed below, the Gramm-Leach-Bliley Act, which was enacted in 1999, established a new type
of bank holding company known as a “financial holding company,” that has powers that are not otherwise available to bank holding companies.

Financial Institutions Reform, Recovery and Enforcement Act of 1989 — The Financial Institutions Reform, Recovery and Enforcement Act of 1989 (FIRREA) 
reorganized and reformed the regulatory structure applicable to financial institutions generally.

The Federal Deposit Insurance Corporation Improvement Act of 1991 — The Federal Deposit Insurance Corporation Improvement Act of 1991 (FDICIA) was 
adopted to supervise and regulate a wide variety of banking issues. In general, FDICIA provides for the recapitalization of the Bank Insurance Fund (BIF), deposit 
insurance reform, including the implementation of risk-based deposit insurance premiums, the establishment of five capital levels for financial institutions (“well 
capitalized,”  “adequately  capitalized,”  “undercapitalized,”  “significantly  undercapitalized,”  and  “critically  undercapitalized”)  that  would  impose  more  scrutiny  and 
restrictions on less capitalized institutions, along with a number of other supervisory and regulatory issues. At December 31, 2006, the Bank was categorized as 
“well capitalized,” meaning that its total risk-based capital ratio exceeded 10.00%, its Tier 1 risk-based capital ratio exceeded 6.00%, its leverage ratio exceeded 
5.00%, and it was not subject to a regulatory order, agreement, or directive to meet and maintain a specific capital level for any capital measure.

Federal Deposit Insurance Reform Act — On February 1, 2006, Congress approved the Federal Deposit Insurance Reform Act of 2005 (FDIRA). Among other 
things, the FDIRA provides for the merger of the Bank Insurance Fund with the Savings Association Insurance Fund and for an immediate increase in Federal 
deposit insurance for certain retirement accounts up to $250,000. The statute further provides for the indexing of the maximum deposit insurance coverage for 
all types of deposit accounts in the future to account for inflation. The FDIRA also requires the FDIC to provide certain banks and thrifts that were in existence prior 
to December 31, 1996 with one-time credits against future premiums based on the amount of their payments to the Bank Insurance Fund or Savings Association 
Insurance Fund prior to that date.

Securities and Exchange Commission (SEC) and The Nasdaq Stock Market (Nasdaq) — We are under the jurisdiction of the SEC and certain state securities 
commissions for matters relating to the offering and sale of our securities and our investment advisory services. We are subject to the disclosure and regulatory 
requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, as administered by the SEC. We are listed on the 
Nasdaq Global Select Market under the trading symbol “SRCE,” and we are subject to the rules of Nasdaq for listed companies. 

Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 — Congress enacted the Riegle-Neal Interstate Banking and Branching Efficiency Act of 
1994 (Interstate Act) in September 1994. Beginning in September 1995, bank holding companies have the right to expand, by acquiring existing banks, into all 
states, even those which had theretofore restricted entry. The legislation also provides that, subject to future action by individual states, a holding company has the 
right to convert the banks which it owns in different states to branches of a single bank. The states of Indiana and Michigan have adopted the interstate branching 
provisions of the Interstate Act.

Economic Growth and Regulatory Paperwork Reduction Act of 1996 — The Economic Growth and Regulatory Paperwork Reduction Act of 1996 (EGRPRA) 
was signed into law on September 30, 1996. Among other things, EGRPRA streamlined the non-banking activities application process for well-capitalized and 
well-managed bank holding companies.

Gramm-Leach-Bliley Act of 1999 — The Gramm-Leach-Bliley Act of 1999 (GLBA) is intended to modernize the banking industry by removing barriers to 
affiliation among banks, insurance companies, the securities industry, and other financial service providers. It provides financial organizations with the flexibility of 
structuring such affiliations through a holding company structure or through a financial subsidiary of a bank, subject to certain limitations. The GLBA establishes 
a new type of bank holding company, known as a financial holding company, which may engage in an expanded list of activities that are “financial in nature,” 
which include securities and insurance brokerage, securities underwriting, insurance underwriting, and merchant banking. The GLBA also sets forth a system of 
functional regulation that makes the Federal Reserve the “umbrella supervisor” for holding companies, while providing for the supervision of the holding company’s 
subsidiaries by other Federal and state agencies. A bank holding company may not become a financial holding company if any of its subsidiary financial institutions 
are not well-capitalized or well-managed. Further, each bank subsidiary of the holding company must have received at least a satisfactory Community Reinvestment 
Act (CRA) rating. The GLBA also expands the types of financial activities a national bank may conduct through a financial subsidiary, addresses state regulation 
of insurance, generally prohibits unitary thrift holding companies organized after May 4, 1999, from participating in new activities that are not financial in nature, 
provides privacy protection for nonpublic customer information of financial institutions, modernizes the Federal Home Loan Bank system, and makes miscellaneous 
regulatory improvements. The Federal Reserve and the Secretary of the Treasury must coordinate their supervision regarding approval of new financial activities 
to be conducted through a financial holding company or through a financial subsidiary of a bank. While the provisions of the GLBA regarding activities that may 
be conducted through a financial subsidiary directly apply only to national banks, those provisions indirectly apply to state-chartered banks. In addition, the Bank 
is subject to other provisions of the GLBA, including those relating to CRA and privacy, regardless of whether we elect to become a financial holding company or 
to conduct activities through a financial subsidiary of the Bank. We do not, however, currently intend to file notice with the Board to become a financial holding 
company or to engage in expanded financial activities through a financial subsidiary of the Bank.

Financial  Privacy  —  In  accordance  with  the  GLBA,  Federal  banking  regulators  adopted  rules  that  limit  the  ability  of  banks  and  other  financial  institutions  to 
disclose non-public information about customers to nonaffiliated third parties. These limitations require disclosure of privacy policies to consumers and, in some 
circumstances, allow consumers to prevent disclosure of certain personal information to a nonaffiliated third party. The privacy provisions of the GLBA affect how 
consumer information is transmitted through diversified financial companies and conveyed to outside vendors.

USA Patriot Act of 2001 — The USA Patriot Act of 2001 (USA Patriot Act) was signed into law primarily as a result of the terrorist attacks of September 11,
2001. The USA Patriot Act is comprehensive anti-terrorism legislation that, among other things, substantially broadened the scope of anti-money laundering laws 
and regulations by imposing significant new compliance and due diligence obligations on financial institutions.

The  regulations  adopted  by  the  United  States  Treasury  Department  under  the  USA  Patriot  Act  impose  new  obligations  on  financial  institutions  to  maintain 
appropriate policies, procedures and controls to detect, prevent and report money laundering, and terrorist financing. Additionally, the regulations require that we, 
upon request from the appropriate Federal regulatory agency, provide records related to anti-money laundering, perform due diligence of private banking and 
correspondent accounts, establish standards for verifying customer identity, and perform other related duties.

15 (cid:127) SRCE 

2006 Form 10-K

Failure of a financial institution to comply with the USA Patriot Act’s requirements could have serious legal and reputational consequences for the institution.

Regulations Governing Capital Adequacy — The Federal bank regulatory agencies use capital adequacy guidelines in their examination and regulation of bank 
holding companies and banks. If capital falls below the minimum levels established by these guidelines, a bank holding company or bank will be required to submit 
an acceptable plan for achieving compliance with the capital guidelines and will be subject to denial of applications and appropriate supervisory enforcement 
actions. The various regulatory capital requirements that we are subject to are disclosed in Part II, Item 8, Financial Statements and Supplementary Data — Note Q 
of the Notes to Consolidated Financial Statements. Our management believes that the risk-weighting of assets and the risk-based capital guidelines does not have 
a material adverse impact on our operations or on the operations of the Bank.

Community Reinvestment Act — The Community Reinvestment Act of 1977 requires that, in connection with examinations of financial institutions within their 
jurisdiction, the Federal banking regulators must 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 banks. Federal banking regulators are required to consider a financial 
institution’s performance in these areas as they review applications filed by the institution to engage in mergers or acquisitions or to open a branch or facility.

t

t

Regulations Governing Extensions of Credit — The Bank is subject to certain restrictions imposed by the Federal Reserve Act on extensions of credit to 1st Source 
or our subsidiaries, or investments in our securities and on the use of our securities as collateral for loans to any borrowers. These regulations and restrictions may 
limit our ability to obtain funds from the Bank for our cash needs, including funds for acquisitions and for payment of dividends, interest and operating expenses. 
Further, the BHCA, certain regulations of the Federal Reserve, state laws and many other Federal laws govern the extensions of credit and generally prohibit a bank 
from extending credit, engaging in a lease or sale of property, or furnishing services to a customer on the condition that the customer obtain additional services 
from the bank’s holding company or from one of its subsidiaries.

The Bank is also subject to certain restrictions imposed by the Federal Reserve Act on extensions of credit to executive officers, directors, principal shareholders, 
or any related interest of such persons. Extensions of credit (i) must be made on substantially the same terms, including interest rates and collateral, and following 
credit underwriting procedures that are at least as stringent as those prevailing at the time for comparable transactions with persons not covered above and who 
are not employees, and (ii) must not involve more than the normal risk of repayment or present other unfavorable features. The Bank is also subject to certain 
lending limits and restrictions on overdrafts to such persons.

Reserve Requirements — The Federal Reserve requires all depository institutions to maintain reserves against their transaction account deposits. Reserves of 
3.00% must be maintained against net transaction accounts greater than $7.80 million and less than $48.3 million (subject to adjustment by the Federal Reserve) 
and reserves of 10.00% must be maintained against that portion of net transaction accounts in excess of $48.3 million.

Dividends — The ability of the Bank to pay dividends and management fees is limited by various state and Federal laws, by certain covenant agreements, by the 
regulations promulgated by its primary regulators, and by the principles of prudent bank management.

Monetary Policy and Economic Control — The commercial banking business in which we engage is affected not only by general economic conditions, but also 
by the monetary policies of the Federal Reserve. Changes in the discount rate on member bank borrowing, availability of borrowing at the “discount window,” open 
market operations, the imposition of changes in reserve requirements against member banks deposits and assets of foreign branches, and the imposition of, and 
changes in, reserve requirements against certain borrowings by banks and their affiliates are some of the instruments of monetary policy available to the Federal 
Reserve. These monetary policies are used in varying combinations to influence overall growth and distributions of bank loans, investments, and deposits, and such 
use may affect interest rates charged on loans and leases or paid on deposits. The monetary policies of the Federal Reserve have had a significant effect on the 
operating results of commercial banks and are expected to do so in the future. The monetary policies of the Federal Reserve are influenced by various factors, 
including inflation, unemployment, short-term and long-term changes in the international trade balance, and in the fiscal policies of the U.S. Government. Future 
monetary policies and the effect of such policies on our future business and earnings, and the effect on the future business and earnings of the Bank cannot be 
predicted.

Sarbanes-Oxley Act of 2002 — On July 30, 2002, the Sarbanes-Oxley Act of 2002 (SOA) was signed into law. The SOA’s stated goals include enhancing 
corporate responsibility, increasing penalties for accounting and auditing improprieties at publicly traded companies and protecting investors by improving the 
accuracy and reliability of corporate disclosures pursuant to the securities laws. The SOA generally applies to all companies that file or are required to file periodic 
reports with the SEC under the Securities Exchange Act of 1934 (Exchange Act).

Among other things, the SOA creates the Public Company Accounting Oversight Board as an independent body subject to SEC supervision with responsibility for 
setting auditing, quality control, and ethical standards for auditors of public companies. The SOA also requires public companies to make faster and more-extensive 
financial disclosures, requires the chief executive officer and the chief financial officer of public companies to provide signed certifications as to the accuracy and 
completeness of financial information filed with the SEC, and provides enhanced criminal and civil penalties for violations of the Federal securities laws.

The SOA also addresses functions and responsibilities of audit committees of public companies. The statute, by mandating certain stock exchange listing rules, 
makes the audit committee directly responsible for the appointment, compensation, and oversight of the work of the company’s outside auditor, and requires the 
auditor to report directly to the audit committee. The SOA authorizes each audit committee to engage independent counsel and other advisors, and requires a 
public company to provide the appropriate funding, as determined by its audit committees, to pay the company’s auditors and any advisors that its audit committee 
retains. The SOA also requires public companies to include an internal control report and assessment by management, along with an attestation to this report 
prepared by the company’s registered public accounting firm, in their annual reports to stockholders.

Pending Legislation — Because of concerns relating to competitiveness and the safety and soundness of the banking industry, Congress often considers a number 
of wide-ranging proposals for altering the structure, regulation, and competitive relationships of the nation’s financial institutions. We cannot predict whether or in 
what form any proposals will be adopted or the extent to which our business may be affected thereby.

ITEM 1A. RISK FACTORS.

An investment in our common stock is subject to risks inherent to our business. The material risk and uncertainties that we believe affect us are described below. 
See “Forward Looking Statements” under Item 7 of this report for a discussion of other important factors that can affect our business.

Fluctuations in interest rates could reduce our profitability and affect the value of our assets — Like other financial institutions, we are subject to interest rate
risk. Our primary source of income is net interest income, which is the difference between interest earned on loans and leases and investments, and interest paid on 
deposits and borrowings. We expect that we will periodically experience imbalances in the interest rate sensitivities of our assets and liabilities and the relationships 
of various interest rates to each other. Over any defined period of time, our interest-earning assets may be more sensitive to changes in market interest rates than 
our interest-bearing liabilities, or vice-versa. In addition, the individual market interest rates underlying our loan and lease and deposit products may not change 
to the same degree over a given time period. In any event, if market interest rates should move contrary to our position, earnings may be negatively affected. In 
addition, loan and lease volume and quality and deposit volume and mix can be affected by market interest rates as can the businesses of our clients. Changes in 
levels of market interest rates could have a material adverse affect on our net interest spread, asset quality, origination volume, and overall profitability.

Over the last two years, the Federal Reserve increased its target for Federal funds rate 400 basis points. While these short-term market interest rates (which are 
used as a guide for pricing deposits) have increased, longer-term market interest rates (which are used as a guide for pricing longer-term loans and leases) have 
not. If short-term interest rates continue to rise, and if rates on our deposits and borrowings continue to reprice upwards faster than the rates on long-term loans 
and leases and investments, we could experience continued compression of our interest rate spread and net interest margin, which could have a negative effect 
on our profitability.

We principally manage interest rate risk by managing the volume and mix of our earning assets and funding liabilities. In a changing interest rate environment, we 
may not be able to manage this risk effectively. If we are unable to manage interest rate risk effectively, our business, financial condition and results of operations 
could be materially harmed.

Changes in the level of interest rates also may negatively affect our ability to originate loans and leases, the value of our assets and our ability to realize gains from 
the sale of our assets, all of which ultimately could affect our earnings.

Future expansion involves risks — In the future, we may acquire all or part of other financial institutions and we may establish de novo branch offices. There could 
be considerable costs involved in executing our growth strategy. For instance, new branches generally require a period of time to generate sufficient revenues to 
offset their costs, especially in areas in which we do not have an established presence. Accordingly, any new branch expansion could be expected to negatively 
impact earnings for some period of time until the branch reaches certain economies of scale. Acquisitions and mergers involve a number of risks, including the risk 
that:

•  We may incur substantial costs identifying and evaluating potential acquisitions and merger partners, or in evaluating new markets, hiring experienced local 

managers, and opening new offices;

•  Our estimates and judgments used to evaluate credit, operations, management, and market risks relating to target institutions may not be accurate;

•  There may be substantial lag-time between completing an acquisition or opening a new office and generating sufficient assets and deposits to support costs of 

the expansion;

•  We  may  not  be  able  to  finance  an  acquisition,  or  the  financing  we  obtain  may  have  an  adverse  effect  on  our  operating  results  or  dilution  of  our  existing 

shareholders;

•  The attention of our management in negotiating a transaction and integrating the operations and personnel of the combining businesses may be diverted from 

our existing business;

•  Acquisitions typically involve the payment of a premium over book and market values and; therefore, some dilution of our tangible book value and net income 

per common share may occur in connection with any future transaction;

•  We may enter new markets where we lack local experience;

•  We may incur goodwill in connection with an acquisition, or the goodwill we incur may become impaired, which results in adverse short-term effects on our 

operating results; or

•  We may lose key employees and clients.

Competition from other financial services providers could adversely impact our results of operations — The banking and financial services business is highly 
competitive. We face competition in making loans and leases, attracting deposits and providing insurance, investment, trust, and other financial services. Increased 
competition in the banking and financial services businesses may reduce our market share, impair our growth or cause the prices we charge for our services to 
decline. Our results of operations may be adversely impacted in future periods depending upon the level and nature of competition we encounter in our various 
market areas.

We are dependent upon the services of our management team — Our future success and profitability is substantially dependent upon our management and the 
banking abilities of our senior executives. We believe that our future results will also depend in part upon our ability to attract and retain highly skilled and qualified 
management. We are especially dependent on a limited number of key management personnel, many of whom do not have employment agreements with us. 
The loss of the chief executive officer and other senior management and key personnel could have a material adverse impact on our operations because other 
officers may not have the experience and expertise to readily replace these individuals. Many of these senior officers have primary contact with our clients and are 
extremely important in maintaining personalized relationships with our client base. The unexpected loss of services of one or more of these key employees could
have a material adverse effect on our operations and possibly result in reduced revenues if we were unable to find suitable replacements promptly. Competition 
for senior personnel is intense, and we may not be successful in attracting and retaining such personnel. Changes in key personnel and their responsibilities may be 
disruptive to our businesses and could have a material adverse effect on our businesses, financial condition, and results of operations.

17 (cid:127) SRCE 

2006 Form 10-K

Technology security breaches could expose us to possible liability and damage our reputation — Any compromise of our security also could deter our clients 
from using our internet banking services that involve the transmission of confidential information. We rely on standard internet security systems to provide the
security and authentication necessary to effect secure transmission of data. These precautions may not protect our systems from compromises or breaches of our 
security measures that could result in damage to our reputation and business. 

Failure to successfully implement a project we have undertaken to replace the majority of our core and ancillary data processing systems, would negatively 
impact our business — During 2006, we continued to work toward the implementation of our new core system. Complete conversion is slated for 2007. The
replacement  of  our  core  systems  has  wide-reaching  impacts  on  our  internal  operations  and  business.  We  can  provide  no  assurance  that  the  amount  of  this 
investment will not exceed our expectations and result in materially increased levels of expense or asset impairment charges. There is no assurance that this 
initiative will achieve the expected cost savings or result in a positive return on our investment. Additionally, if our new core system does not operate as intended, or 
is not implemented as planned, there could be disruptions in our business which could adversely affect our financial condition and results of operations.

We are subject to credit risks relating to our loan and lease portfolios — We have certain lending policies and procedures in place that are designed to optimize 
loan and lease income within an acceptable level of risk. Our management reviews and approves these policies and procedures on a regular basis. A reporting 
system supplements the review process by providing our management with frequent reports related to loan and lease production, loan quality, concentrations 
of credit, loan and lease delinquencies, and nonperforming and potential problem loans and leases. Diversification in the loan and lease portfolios is a means of 
managing risk associated with fluctuations and economic conditions. 

We maintain an independent loan review department that reviews and validates the credit risk program on a periodic basis. Results of these reviews are presented 
to our management. The loan and lease review process complements and reinforces the risk identification and assessment decisions made by lenders and credit 
personnel, as well as our policies and procedures.

In the financial services industry, there is always a risk that certain borrowers may not repay borrowings. Our reserve for loan and lease losses may not be sufficient 
to cover the loan and lease losses that we may actually incur. If we experience defaults by borrowers in any of our businesses, our earnings could be negatively 
affected. Changes in local economic conditions could adversely affect credit quality, particularly in our local business loan and lease portfolio. Changes in national 
economic conditions could also adversely affect the quality of our loan and lease portfolio and negate, to some extent, the benefits of national diversification through 
our Specialty Finance Group’s portfolio. 

Commercial and commercial real estate loans generally involve higher credit risks than residential real estate and consumer loans. Because payments on loans 
secured by commercial real estate or equipment are often dependent upon the successful operation and management of the underlying assets, repayment of such
loans may be influenced to a great extent by conditions in the market or the economy. We seek to minimize these risks through our underwriting standards. We 
obtain financial information and perform credit risk analysis on our customers. Credit criteria may include, but are not limited to, assessments of income, cash flows, 
and net worth; asset ownership; bank and trade credit reference; credit bureau report; and operational history. 

Commercial real estate or equipment loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and generate positive 
cash flows. Our management examines current and projected cash flows of the borrower to determine the ability of the borrower to repay their obligations as 
agreed. Underwriting standards are designed to promote relationship banking rather than transactional banking. Most commercial and industrial loans are secured 
by the assets being financed or other business assets; however, some loans may be made on an unsecured basis. Our credit policy sets different maximum exposure 
limits both by business sector and our current and historical relationship and previous experience with each customer. 

We offer both fixed-rate and adjustable-rate consumer mortgage loans secured by properties, substantially all of which are located in our primary market area. 
Adjustable-rate  mortgage  loans  help  reduce  our  exposure  to  changes  in  interest  rates;  however,  during  periods  of  rising  interest  rates,  the  risk  of  default  on 
adjustable-rate  mortgage  loans  may  increase  as  a  result  of  repricing  and  the  increased  payments  required  from  the  borrower.  Additionally,  most  residential 
mortgages are sold into the secondary market and serviced by our mortgage subsidiary, Trustcorp.

Consumer loans are primarily all other non-real estate loans to individuals in our regional market area. Consumer loans can entail risk, particularly in the case of 
loans that are unsecured or secured by rapidly depreciating assets. In these cases, any repossessed collateral may not provide an adequate source of repayment 
of the outstanding loan balance. The remaining deficiency often does not warrant further substantial collection efforts against the borrower beyond obtaining a 
deficiency judgment. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be adversely 
affected by job loss, divorce, illness, or personal bankruptcy.

The 1st Source Specialty Finance Group loan and lease portfolio consists of commercial loans and leases secured by construction and transportation equipment, 
including  aircraft,  autos,  trucks,  and  vans.  Finance  receivables  for  this  Group  generally  provide  for  monthly  payments  and  may  include  prepayment  penalty 
provisions.

Our construction and transportation related businesses could be adversely affected by slow downs in the economy. Clients who rely on the use of assets financed 
through the Specialty Finance Group to produce income could be negatively affected, and we could experience substantial loan and lease losses. By the nature of 
the businesses these clients operate in, we could be adversely affected by continued rapid increases of fuel costs. Since some of the relationships in these industries 
are large (up to $15 million), a slow down could have a significant adverse impact on our performance. 

Our construction and transportation related businesses could be adversely impacted by the negative effects caused by high fuel costs, terrorist attacks, potential 
attacks, and other destabilizing events. These factors could contribute to the deterioration of the quality of our loan and lease portfolio, as they could have a negative 
impact on the travel sensitive businesses for which our specialty finance businesses provide financing.

In addition, our leasing and equipment financing activity is subject to the risk of cyclical downturns, industry concentration and clumping, and other adverse economic 
developments affecting these industries and markets. This area of lending, with transportation in particular, is dependent upon general economic conditions and the 
strength of the travel, construction, and transportation industries.

ITEM 2. PROPERTIES.

Our headquarters building is located in downtown South Bend. In 1982, the land was leased from the City of South Bend on a 49-year lease, with a 50-year 
renewal option. The building is part of a larger complex, including a 300-room hotel and a 500-car parking garage. Also, in 1982, we sold the building and entered 
into a leaseback agreement with the purchaser for a term of 30 years. The building is a structure of approximately 160,000 square feet, with 1st Source and our 
subsidiaries occupying approximately 70% of the available office space and approximately 30% subleased to unrelated tenants.

At December 31, 2006, we also owned property and/or buildings on which 46 of the Bank subsidiary’s 67 banking centers were located, including the facilities in 
Allen, Elkhart, Fulton, Huntington, Kosciusko, LaPorte, Marshall, Porter, St. Joseph, Starke, and Wells Counties in the State of Indiana and Berrien and Cass Counties 
in the State of Michigan, as well as an operations center, training facility, warehouse, and our former headquarters building, which is utilized for additional business 
operations. The Bank leases additional property and/or buildings to and from third parties under lease agreements negotiated at arms-length.

1st Source and our subsidiaries are involved in various legal proceedings incidental to the conduct of our businesses. Our management does not expect that the 
outcome of any such proceedings will have a material adverse effect on our consolidated financial position or results of operations.

EXECUTIVE SUMMARY

Our mission is to help individuals, institutions, businesses, and communities achieve security, build wealth, and realize their dreams. We accomplish our mission by 
maintaining a high degree of integrity, offering outstanding client service, attaining superior quality in everything we do, working as a team, and providing leadership 
in the communities we serve.

We have established goals in our 2010 strategic plan which are being driven by six initiatives — develop our people; vitalize sales; roll out full services in all markets; 
open new markets; upgrade our core systems; and achieve superior financial performance.

In order to meet our 2010 objectives we have focused our staff development on recruiting, hiring, and retaining employees who share our core values of being 
accessible and attentive to the needs of our clients. To vitalize sales, we opened newly designed banking centers to give better service and more convenience to 
our customers. We focused on small business clients and became the #1 SBA lender in Northern Indiana and Southwestern Michigan in 2006; and we piloted a 
program of retail bankers who became “micro-lenders” serving the needs of small business clients. In Fort Wayne, we added private banking, agricultural and small 
business banking, investment and asset management, and business banking to our service offerings. In our retail banking system, we added asset advisors to assist 
our clients in investments and we opened a new banking center in our traditional market.

In 2006, we also focused on opening in totally new markets. To gain new clients, we opened a facility in Kalamazoo which will initially focus on private banking and 
small business clients; and have hired leadership for our efforts in Lafayette, Indiana which will open in 2007. Additionally, we conducted significant analysis on 
areas within our own markets and across the country to showcase opportunities where 1st Source might expand through de novo branching or acquisitions. Our 
goal is to find acquisition partners that are culturally similar and possess significant market presence or have potential for improved profitability through financial 
management,  economies  of  scale,  and  expanded  services.  Consistent  with  our  goal  of  growth  market  expansion,  on  February  19,  2007,  we  announced  the 
agreement and plan of merger with FINA Bancorp, Inc., the parent company of First National Bank, Valparaiso. Pending customary closing conditions, including 
regulatory approval, we expect the merger to be completed in the second quarter of 2007. We believe this acquisition provides us with an opportunity to join two 
strong local banks with similar values, history, and legacies. First National Bank, Valparaiso is located in the fastest growing area of our retail market and will serve 
as a platform for future expansion.

None of this can be accomplished without the proper infrastructure. We are in the process of replacing our core accounting and management systems that will 
allow us to grow and expand by becoming more effective and efficient. A major portion of this will be installed during 2007.

CRITICAL ACCOUNTING POLICIES

Our consolidated financial statements are prepared in accordance with U. S. generally accepted accounting principles and follow general practices within the 
industries in which we operate. Application of these principles requires our management to make estimates or judgments that affect the amounts reported in the 
financial statements and accompanying notes. These estimates or judgments reflect our management’s view of the most appropriate manner in which to record 
and report our overall financial performance. Because these estimates or judgments are based on current circumstances, they may change over time or prove 
to be inaccurate based on actual experience. As such, changes in these estimates, judgments, and/or assumptions may have a significant impact on our financial 
statements. All accounting policies are important, and all policies described in Part II, Item 8, Financial Statements and Supplementary Data, Note A (Note A), 
should be reviewed for a greater understanding of how our financial performance is recorded and reported.

We have identified three policies as being critical because they require our management to make particularly difficult, subjective, and/or complex estimates or 
judgments about matters that are inherently uncertain and because of the likelihood that materially different amounts would be reported under different conditions 
or using different assumptions. These policies relate to the determination of the reserve for loan and lease losses, the valuation of mortgage servicing rights, and 
the valuation of securities. Our management has used the best information available to make the estimations or judgments necessary to value the related assets 
and liabilities. Actual performance that differs from estimates or judgments and future changes in the key variables could change future valuations and impact 
net income. Our management has reviewed the application of these policies with the Audit Committee of the Board of Directors. A brief discussion of our critical 
accounting policies appears below. 

Reserve for Loan and Lease Losses — The reserve for loan and lease losses represents our management’s estimate of probable losses inherent in the loan and 
lease portfolio and the establishment of a reserve that is sufficient to absorb those losses. In determining an adequate reserve, our management makes numerous 
judgments, assumptions, and estimates based on continuous review of the loan and lease portfolio, estimates of future client performance, collateral values, and 
disposition, as well as historical loss rates and expected cash flows. In assessing these factors, our management benefits from a lengthy organizational history and 
experience with credit decisions and related outcomes. Nonetheless, if our management’s underlying assumptions prove to be inaccurate, the reserve for loan 
and lease losses would have to be adjusted. Our accounting policy related to the reserve is disclosed in Note A under the heading “Reserve for Loan and Lease 
Losses.”

Mortgage Servicing Rights Valuation — We recognize as assets the rights to service mortgage loans for others, known as mortgage servicing rights whether the 
servicing rights are acquired through purchases or through originated loans. Mortgage servicing rights do not trade in an active open market with readily observable 
market prices. Although sales of mortgage servicing rights do occur, the precise terms and conditions may not be readily available. As such, the value of mortgage 
servicing assets are established and valued using discounted cash flow modeling techniques which require management to make estimates regarding estimated 
future net servicing cash flows, taking into consideration actual and expected mortgage loan prepayment rates, discount rates, servicing costs, and other economic 
factors. The expected and actual rates of mortgage loan prepayments are the most significant factors driving the value of mortgage servicing assets. Increases in 
mortgage loan prepayments reduce estimated future net servicing cash flows because the life of the underlying loan is reduced. In determining the fair value of 
the mortgage servicing assets, mortgage interest rates (which are used to determine prepayment rates), and discount rates are held constant over the estimated
life of the portfolio. Expected mortgage loan prepayment rates are derived from a third-party model and adjusted to reflect our actual prepayment experience. 
Mortgage servicing assets are carried at the lower of the initial capitalized amount, net of accumulated amortization or fair value. The values of these assets are 
sensitive to changes in the assumptions used and readily available market pricing does not exist. The valuation of mortgage servicing assets is discussed further in 
Note A under the heading “Mortgage Banking Activities.”

Valuation of Securities —Our available-for-sale security portfolio is reported at fair value. The fair value of a security is determined based on quoted market prices. 
If quoted market prices are not available, fair value is determined based on quoted prices of similar instruments. Available-for-sale and held-to-maturity securities 
are reviewed quarterly for possible other-than-temporary impairment. The review includes an analysis of the facts and circumstances of each individual investment 
such as length of time the fair value has been below cost, the expectation for that security’s performance, the credit worthiness of the issuer, and our intent and 
ability to hold the security for a time necessary to recover the amortized cost. A decline in value that is considered to be other-than-temporary is recorded as 
investment securities and other investment losses in the Consolidated Statements of Income. The valuation of securities is discussed further in Note A under the 
heading “Securities.”

EARNINGS SUMMARY

Net income in 2006 was $39.30 million, up from $33.75 million in 2005 and up from $24.97 million in 2004. We declared a 10% stock dividend on July 
27, 2006; therefore, all share and per share information has been adjusted accordingly. Diluted net income per common share was $1.72 in 2006, $1.46 in 
2005, and $1.08 in 2004. Return on average total assets was 1.11% in 2006 compared to 1.00% in 2005, and 0.75% in 2004. Return on average common 
shareholders’ equity was 10.98% in 2006 versus 10.12% in 2005, and 7.81% in 2004.

Net income in 2006 was favorably affected by a strong increase in noninterest income that was primarily related to solid progress in growing our leased equipment 
portfolio during the year and positive market valuation adjustments related to our investments in venture partnerships. Net interest income improved 8.13% for 
2006 over 2005. The improvement in net interest income was driven primarily by an increase in average earning assets; however, the higher cost of deposits 
greatly offset the increase in average earning assets. Noninterest expense increased moderately in 2006 as compared to 2005. Net income in 2005 was favorably 
affected by a recovery in the provision for loan and lease losses, a reduction in loan and lease collection and repossession expense, and decreased professional 
fee expense. In addition, income from deposit fees increased and losses on investment securities decreased notably from 2005 and 2004. Equipment rental 
income decreased and depreciation on leased equipment decreased accordingly in 2005 from 2004. We did not record any other-than-temporary impairment 
on investment securities in 2006. Net income included $0.61 million and $4.78 million of other-than-temporary impairment on investment securities, for 2005 
and 2004, respectively.

Dividends paid on common stock in 2006 amounted to $0.534 per share, compared to $0.445 per share in 2005, and $0.382 per share in 2004. The level 
of earnings reinvested and dividend payouts are based on management’s assessment of future growth opportunities and the level of capital necessary to support 
them.

Upgrade  of  Core  Systems —  On  December  1,  2005,  1st  Source  Bank,  entered  into  a  license  and  service  agreement  with  Fiserv  Solutions,  Inc.  (Fiserv),  a
subsidiary of Fiserv, Inc. The agreement was an integral part of the decision we made to upgrade a majority of our core and ancillary data processing systems. We 
expect the completion of core systems upgrade will increase the effectiveness and efficiency of our operations and facilitate future growth. We also expect that, 
over time, this investment should be offset by elimination of current costs for ongoing support of the current technology platform.

Under the agreement, 1st Source and our affiliates are licensing integrated core technology and ancillary systems from Fiserv. The core technology licensing 
includes  a  loan  system,  deposit  system,  general  ledger  system,  and  customer  information  file  system.  Fiserv  is  obligated  to  provide  professional  services  for 
installation of the technology and training, and maintenance support services. The agreement provides an initial five year maintenance period to begin no later than 
March 2007. The agreement provides for automatic renewal of the maintenance period, after the initial five year term, unless either party notifies the other of its 
intent not to renew. We are subject to termination fees for early termination of the maintenance period. We expect the initial cost will be approximately $6.0 million 
for the technology licenses, professional fees for installation and training, and hardware delivered under the Fiserv agreement. 

During 2006, we worked to organize the various components of this large conversion effort. Numerous internal teams have been formed to manage the installation 
and conversion of data and various systems. Additionally, ATM networks, a voice response unit (VRU) system, and document imaging systems have been or are 
being installed. We are relying on several third party vendors to integrate several systems, including internet banking and cash management. Our intent is to convert 
independent  systems,  such  as  the legacy  centralized  information  repository and  document  image  systems,  as  they  are  ready.  Our  goal  is  to  convert  the  core 
systems in 2007. Our timeframe for conversion could be impacted by the delivery of systems from outside vendors, as well as our own internal testing. We will 
implement these new systems only when we are confident and certain of their successful conversion. We look forward to the implementation of new core systems 
and their impact on the effectiveness and efficiency of our operations and the increased functionality that will facilitate future growth.

Net Interest Income — Our primary source of earnings is net interest income, the difference between income on earning assets and the cost of funds supporting 
those assets. Significant categories of earning assets are loans and securities while deposits and borrowings represent the major portion of interest-bearing liabilities. 
For purposes of the following discussion, comparison of net interest income is done on a tax equivalent basis, which provides a common basis for comparing yields 
on earning assets exempt from federal income taxes to those which are fully taxable. 

Net interest margin (the ratio of net interest income to average earning assets) is affected by movements in interest rates and changes in the mix of earning assets 
and the liabilities that fund those assets. Net interest margin on a fully taxable equivalent basis was 3.29% in 2006 compared to 3.21% in 2005, and 3.25% 
in 2004. Our focus on loan and lease portfolio credit quality coupled with increased competition for deposits across all markets offset efforts to improve the net 
interest margin resulting in nominal changes in our net interest margin for the past three years.

Net interest income was $106.43 million for 2006, compared to $98.43 million for 2005. Tax-equivalent net interest income totaled $108.98 million for 2006, 
an increase of $7.88 million from the $101.10 million reported for 2005. The increase reflects a $5.97 million increase due to increased volume and a $1.91 
million increase due to rate changes on the underlying assets and liabilities.

During 2006, average earning assets increased $162.87 million while average interest-bearing liabilities increased $189.66 million over the comparable period. 
The yield on average earning assets increased 95 basis points to 6.38% for 2006 from 5.43% for 2005. The rate earned on assets was positively impacted by 
the continued increases in short-term market interest rates throughout 2005 and the first two quarters of 2006. Total cost of average interest-bearing liabilities 
increased 98 basis points during 2006 as liabilities were also affected by increases in short-term market interest rates. The result was a decrease of three basis 
points to net interest spread, or the difference between interest income on earning assets and expense on interest-bearing liabilities. Our tax-equivalent net interest 
margin of 3.29% for 2006 was a moderate increase from 3.21% in 2005.

The largest contributor to the increase in the yield on average earning assets in 2006, on a volume-weighted basis, was the $217.53 million increase in net loans 
and leases. The loan and lease portfolio contributed approximately $34.83 million to the change in interest income, while the portfolio’s average yield increased 
84 basis points from the prior year to 6.94%. 

During 2006, the tax-equivalent yield on securities available for sale increased 103 basis points to 4.23% while the average balance decreased $58.51 million. 
Although the portfolio decreased through the year, the average tax-equivalent yield increased due to the addition of higher-rate securities and the maturities of 
lower-rate securities. Funds received from the maturities, calls, and sales of investment securities helped fund loan growth.

Average interest-bearing deposits increased $200.42 million during 2006 while the effective rate paid on those deposits increased 98 basis points. The increase 
in the average cost of interest-bearing deposits was primarily the result of increases in interest rates offered on deposit products due to increases in short-term 
market interest rates and increased competition for deposits across all markets. 

Average demand deposits decreased $40.27 million during 2006. Much of the decline was attributed to fact that clients preferred the interest provided on fixed-
term Certificates on Deposit over the liquidity provided by noninterest bearing deposit accounts and low interest bearing savings accounts. 

Average short-term borrowings decreased $29.45 million during 2006; however, the effective rate paid increased 122 basis points. Average subordinated notes 
which represent our trust preferred borrowings remained unchanged from 2005 to 2006 while the effective rate increased 53 basis points. Interest paid on 
short-term and trust preferred borrowings increased due to the interest rate increase in adjustable rate borrowings. Average long-term debt increased $18.68 
million during 2006 as the effective rate declined 32 basis points. The majority of the increase in long-term debt was made up of Federal Home Loan Bank (FHLB) 
borrowings.

The following table provides an analysis of net interest income and illustrates interest income earned and interest expense charged for each major component of 
interest earning assets and the interest bearing liabilities. Yields/rates are computed on a tax-equivalent basis, using a 35% rate. Nonaccrual loans and leases are 
included in the average loan and lease balance outstanding.

Noninterest income increased 11.75% in 2006 over 2005 mainly due to increases in the operating lease portfolio that resulted in increased equipment rental 
income; market valuation adjustments that resulted in gains on venture partnership investments; growth in assets under management and an increase in IRA 
custodian revenue that resulted in increased trust fee income; and increased overdraft and NSF activity that resulted in increased service charges on deposit 
accounts. Noninterest income increased 9.25% in 2005 from 2004 mainly due to recoveries of mortgage servicing rights impairment, decreased charges for 
other-than-temporary impairment of securities, and market valuation adjustments resulting in gains on partnership investments. 

Equipment rental income generated from operating leases grew by 18.08% during 2006 from 2005 compared to a decrease of 14.79% in 2005 from 2004. 
Revenues from operating leases for construction equipment, various trucks, and other equipment increased as clients responded positively to our strong marketing 
efforts and entered into new lease agreements over the course of 2006. Revenues for 2005 were negatively affected due to maturities of leases and revenues for 
2004 were negatively affected as clients opted to take advantage of the tax benefits available for purchases of equipment versus equipment rental.

Investment securities and other investment gains totaled $2.00 million for the year ended 2006 compared to $0.35 million for the year ended 2005. Favorable 
market  valuation  adjustments  on  our  venture  partnership  investments  during  2006  were  the  main  factor  contributing  to  the  gains.  Gains  on  venture  capital 
investments  during  2005  were  partially  offset  by  other-than-temporary  impairment  of  $0.61  million  for  2005.  In  2004,  investment  securities  and  other 
investment losses totaled $4.72 million, of this amount $4.58 million was comprised of other-than-temporary impairment charges on investments in Federal 
National Mortgage Association (FNMA) and the Federal Home Loan Mortgage Corporation (FHLMC) preferred stock. 

Service charges on deposit accounts increased 7.12% in 2006 from 2005 compared to an increase of 9.53% in 2005 from 2004. Growth in the number of 
deposit accounts led to increased consumer NSF and overdraft fees.

Trust fees (which includes investment management fees, estate administration fees, mutual fund fees, annuity fees, and fiduciary fees) increased by 7.21% in 
2006 from 2005 compared to an increase of 4.17% in 2005 over 2004. Trust fees are largely based on the size of client relationships and the market value 
and mix of assets under management. The market value of trust assets under management at December 31, 2006 and 2005, were $2.98 billion and $2.66 
billion, respectively. At December 31, 2006, these trust assets were comprised of $1.49 billion of personal and agency trusts, $1.03 billion of employee benefit 
plan assets, $358.84 million of estate administration assets, and $98.56 million of custody assets. Growth in trust fees was mainly attributed to an increase in 
assets under management coupled with a stronger stock and bond market in 2006. A weaker stock and bond market slowed the growth of trust fees in 2005 
from 2004. 

Mortgage banking income increased 7.08% in 2006 over 2005, compared to an increase of 13.77% in 2005 from 2004. The increase in 2006 was primarily 
due to $4.75 million, pre-tax gains on bulk sales of mortgage servicing rights related to both governmental and conventional loans that occurred during the 
second  and  third  quarters.  The  increase  in  2005  was  primarily  the  result  of  a  recovery  of  impairment  on  mortgage  servicing  assets  of  $2.27  million  versus 
impairment  recoveries  of  $0.28  million  during  2004.  During  2006  and  2005,  we  determined  that  no  permanent  write-down  was  necessary  for  previously 
recorded impairment on mortgage servicing assets. Mortgage production declined 17.96% during 2006 compared to 2005 as the Bank and Trustcorp, jointly, 
produced $678.14 million in new mortgages — $103.00 million through the Bank; $126.89 million through Trustcorp; and $448.25 million from wholesale 
production sources. During 2005, the Bank and Trustcorp together produced $826.63 million in new mortgages — $139.06 million through the Bank; $214.05 
million through Trustcorp; and $473.52 million purchased from wholesale production sources.

Insurance commissions were up 10.67% in 2006 from 2005 compared to an increase of 11.85% in 2005 from 2004. The increases for 2006 and 2005 were
mainly attributed to higher contingent commissions and new business sales growth, respectively.

Other income remained relatively unchanged in 2006 as compared to 2005, compared to a decrease of 4.38% in 2005 from 2004. The decline in other income 
during 2005 was primarily the result of lower standby letter of credit fee income which decreased by $0.17 million and miscellaneous fee income which decreased 
by $0.31 million.

In 2006 we experienced an increase in noninterest expense of 2.25% from 2005 compared to a decrease of 2.87% in 2005 from 2004. The leading factors 
contributing to the increase in noninterest expense in 2006 were increased depreciation expense on leased equipment, lower gains and valuation adjustments on 
repossessed assets, and higher professional fees. The increase in 2006 was partially offset by decreases in salaries and employee benefits, net occupancy expense, 
and intangible asset amortization. The decline in noninterest expense in 2005 was mostly due to reduced professional fees, decreased depreciation on leased 
equipment, and a decline in loan and lease collection and repossession expenses. 

Total salaries and employee benefits decreased 4.53% in 2006 from 2005, following a 10.60% increase in 2005 from 2004. 

Employee salaries decreased 5.56% in 2006 compared to an increase of 7.65% in 2005. The decrease in salaries in 2006 was primarily due to the first quarter 
2006  reversal  of  previously  recognized  stock-based  compensation  expense  under  historical  accounting  methods  related  to  the  estimated  forfeiture  of  stock 
awards. This one-time expense reversal, combined with the adoption of Statement of Financial Accounting Standards No. 123(R), Share-based Payment, (SFAS 
No. 123(R)) estimated forfeiture accounting requirements, resulted in a reduction in stock-based compensation of $2.07 million, pre-tax, for the year. The increase 
in salaries in 2005 was primarily the result of merit-based and market-driven salary increases and increased commissions due to higher insurance revenues.

Employee benefits remained relatively stable in 2006, following a 23.70% increase in 2005. We were able to contain employee benefit costs during 2006 as our 
group insurance costs for 2006 were maintained close to 2005 levels.

Occupancy expense decreased 3.32% in 2006 from 2005, compared to a 7.68% increase in 2005 from 2004. The decrease in 2006 was primarily driven 
by lower depreciation expense than that experienced in 2005. The increase in 2005 was primarily due to higher leasehold improvements and repair of premises 
expenses.

Furniture and equipment expense, including depreciation, increased in 2006 over 2005 by 7.86%, compared to a 10.96% increase in 2005 from 2004. Higher 
software costs which were mostly related to implementation of upgrades to our core accounting and management systems, and higher debit card transaction 
expense were the significant factors contributing to the increased costs in 2006. The leading causes for the increase in 2005 were increased third-party processing 
charges and desktop computer upgrades. 

Depreciation on equipment owned under operating leases increased 16.00% in 2006 from 2005, following a 15.80% decrease in 2005 from 2004. In 2006, 
depreciation on equipment owned under operating leases increased in conjunction with the increase in equipment rental income as some of our clients opted 
to enter into new lease arrangements rather than purchase equipment. Conversely, during 2005, depreciation on operating leases declined in conjunction with 
the decline in noninterest income from equipment owned under operating leases due to maturities in the operating lease portfolio and clients who opted to take 
advantage of the tax benefits available for purchases of equipment versus equipment rental during 2004. 

Professional fees increased 18.92% in 2006 from 2005, compared to a 48.77% decrease in 2005 from 2004. The majority of the increase in 2006 was due 
to higher legal fees and audit and examination fees which were mainly incurred in the normal course of business. The decrease in 2005 was mainly due to the 
settlement, during the fourth quarter of 2004, of the lawsuit described in the 2003 Form 10-K Item 3, Legal Proceedings and a reduction in the associated legal 
fees.

Supplies and communications expense remained relatively unchanged in 2006 as compared to 2005. Supplies and communications expense decreased 4.31% 
in 2005 from 2004. The decrease in 2005 was primarily due to lower charges for postage and freight and telephone service. 

Business development and marketing expense increased 10.41% in 2006 from 2005. The increase in 2006 was mainly due to robust marketing related to the 
opening of new branches and expansion of our business into the Kalamazoo area. Business development and marketing expense remained relatively steady for 
the year 2005 as compared to 2004. 

Intangible asset amortization decreased 28.28% in 2006 from 2005 compared to a 1.22% increase in 2005 from 2004. The decrease in intangible asset 
amortization  for  2006  was  primarily  due  to  the  effects  of the  complete amortization  of  assets  associated  with  acquisitions  which  occurred  during  2001.  The 
increase in 2005 was due to amortization related to an insurance agency acquisition made during the year. 

Loan and lease collection and repossession expenses increased 164.35% (or $1.80 million) in 2006 as compared to 2005. Loan and lease collection and 
repossession expenses decreased 122.12% (or $6.04 million) in 2005 from 2004. The increase in 2006 was mainly due to lower gains on the disposition of
repossessed assets as we continued to vigorously dispose of our inventory of repossessed assets. In 2005 and 2004, valuation adjustments on repossessed assets 
continued to decrease along with a decrease in legal and collection expenses. From 2003 through 2005, we took back 72 aircraft in repossession and all of those 
repossessed aircraft had been disposed of as of December 31, 2006. 

Other expenses increased 14.99% in 2006 as compared to 2005. The increase was largely due to losses related to an employee defalcation and expenses 
related to employee training and education and relocation. A decrease of 2.05% occurred in other expenses during 2005, compared to 2004. Lower insurance 
cost was the primary factor for the decline for 2005.

Income Taxes — 1st Source recognized income tax expense in 2006 of $20.25 million, compared to $15.63 million in 2005, and $9.14 million in 2004. The 
effective tax rate in 2006 was 34.00% compared to 31.65% in 2005, and 26.79% in 2004. The effective tax rate increased in 2006 due to a decrease in tax-
exempt interest in relation to taxable income. For detailed analysis of 1st Source’s income taxes see Part II, Item 8, Financial Statements and Supplementary Data 
— Note N of the Notes to Consolidated Financial Statements.

At December 31, 2006, 16.9% and 12.6% of total loans and leases were concentrated with borrowers in trucking and truck leasing and construction end users, respectively.

Average loans and leases, net of unearned discount, increased 9.26% and 4.85% in 2006 and 2005, respectively. Loans and leases, net of unearned discount, at 
December 31, 2006, were $2.70 billion and were 70.98% of total assets, compared to $2.46 billion and 70.16% of total assets at December 31, 2005.

Commercial and agricultural lending, excluding those loans secured by real estate, increased 5.54% in 2006 over 2005. Commercial and agricultural lending 
outstandings  were  $478.31  million  and  $453.20  million  at  December  31,  2006  and  December  31,  2005,  respectively.  This  increase  was  mainly  due  to 
increased sales activity within the commercial loan and small business loan areas coupled with improved market conditions and market expansion. 

Loans secured by real estate increased 5.19% during 2006 over 2005. Loans secured by real estate outstanding at December 31, 2006, were $632.28 
million and $601.08 million at December 31, 2005. The primary focus of this lending area is commercial real estate ($412.52 million at December 31, 2006, 
the majority of which is owner occupied) and residential mortgage lending ($219.76 million at December 31, 2006) in the regional market area. This increase 
was mostly due to business clients’ continued investment in real estate for expansion or relocation of their commercial facilities and our ability to meet those 
funding needs.

2006 Form 10-K

 
 
Auto, light truck, and environmental equipment financing increased 2.19% in 2006 over 2005. At December 31, 2006, auto, light truck, and environmental 
equipment financing had outstandings of $317.60 million and $310.79 million at December 31, 2005. Environmental equipment financing increased 21.07% in 
2006 over 2005, most of this increase was in the municipal equipment lease portfolio as a result of focused sales activity. Auto and light truck financing decreased
4.93% at December 31, 2006 compared to December 31, 2005, mainly due to car rental companies reducing their inventories during the off-season in order 
to avoid higher interest costs.

Medium and heavy duty truck loans and leases experienced growth of $39.61 million, or an increase of 13.11%, in 2006. Medium and heavy duty truck financing 
at December 31, 2006 and 2005, had outstandings of $341.74 million and $302.14 million, respectively. Most of the increase at December 31, 2006 from 
December 31, 2005 can be attributed to clients’ making proactive decisions to contain their future costs by completing purchases of 2007 new tractor needs in 
2006. Most of our clients were affected by a new regulatory standard which mandated that, effective January 1, 2007, all Class 8 diesel trucks produced have 
emission compliant engines. This requirement will increase the cost of each vehicle approximately $6,000 to $9,000. 

Aircraft financing at year-end 2006 increased 8.54% from year-end 2005. Aircraft financing at December 31, 2006 and 2005, had outstandings of $498.91 
million and $459.65 million, respectively. The increase in 2006 was primarily due to rigorous marketing efforts and a strong focus on sales. 

Construction  equipment  financing  increased  36.46%  in  2006  over  2005.  Construction  equipment  financing  at  December  31,  2006,  had  outstandings  of 
$305.98 million, compared to outstandings of $224.23 million at December 31, 2005. The increase at December 31, 2006 from December 31, 2005 was 
mainly the result of continued strong commercial, industrial, and non-residential building industries, as well as, substantial Federal, state and local funding for 
roads, bridges, and general transportation projects upon which our client base relies for business. During 2006, we added two new sales territories which further 
enhanced growth in this portfolio.

Consumer loans increased 13.66% in 2006 over 2005. Consumer loans outstanding at December 31, 2006, were $127.71 million and $112.36 million at

CREDIT EXPERIENCE

Reserve for Loan and Lease Losses — Our reserve for loan and lease losses is provided for by direct charges to operations. Losses on loans and leases are charged 
against the reserve and likewise, recoveries during the period for prior losses are credited to the reserve. Our management evaluates the adequacy of the reserve 
quarterly, reviewing all loans and leases over a fixed-dollar amount ($100,000) where the internal credit rating is at or below a predetermined classification, actual 
and anticipated loss experience, current economic events in specific industries, and other pertinent factors including general economic conditions. Determination of 
the reserve is inherently subjective as it requires significant estimates, including the amounts and timing of expected future cash flows or fair value of collateral on 
collateral-dependent impaired loans and leases, estimated losses on pools of homogeneous loans and leases based on historical loss experience, and consideration 
of economic trends, all of which may be susceptible to significant and unforeseen changes. We review the status of the loan and lease portfolio to identify borrowers 
that might develop financial problems in order to aid borrowers in the handling of their accounts and to mitigate losses. See Part II, Item 8, Financial Statements 
and Supplementary Data — Note A of the Notes to Consolidated Financial Statements for additional information on management’s evaluation of the adequacy of 
the reserve for loan and lease losses.

The reserve for loan and lease losses at December 31, 2006 totaled $58.80 million and was 2.18% of loans and leases, compared to $58.70 million or 2.38% 
of loans and leases at December 31, 2005 and $63.67 million or 2.79% of loans and leases at December 31, 2004. It is our opinion that the reserve for loan 
and lease losses was adequate to absorb losses inherent in the loan and lease portfolio as of December 31, 2006.

The recovery of provision for loan and lease losses was $2.74 million and $5.86 million for 2006 and 2005, respectively, compared to the provision for loan and 
lease losses of $0.23 million in 2004. The recovery of the provision for 2006 and 2005 was consistent with our improved credit quality of the loan and lease 
portfolio.

Nonperforming Assets — Our policy is to discontinue the accrual of interest on loans and leases where principal or interest is past due and remains unpaid for 
90 days or more, except for mortgage loans, which are placed on nonaccrual at the time the loan is placed in foreclosure and consumer loans that are both well 
secured and in the process of collection. Nonperforming assets amounted to $17.67 million at December 31, 2006, compared to $22.04 million at December 
31, 2005, and $33.21 million at December 31, 2004. Impaired loans and leases totaled $12.32 million, $16.87 million, and $45.39 million at December 31, 
2006, 2005, and 2004, respectively. During 2006, interest income that would have been recorded on nonaccrual loans and leases under their original terms 
was $1.90 million, compared to $2.19 million in 2005. Interest income that was recorded on nonaccrual loans and leases was $0.62 million and $0.81 million 
in 2006 and 2005, respectively.

Nonperforming assets at December 31, 2006, decreased 19.84% from December 31, 2005. During 2006, decreases in repossessed assets, commercial and 
agricultural loans, construction equipment financing, auto, light truck and environmental equipment, other real estate, and consumer loans were partially offset by 
increases in medium and heavy duty truck, loans secured by real estate, and aircraft financing.

Potential Problem Loans and Leases — At December 31, 2006, the Bank had a $2.95 million standby letter of credit outstanding which supported bond 
indebtedness of a customer. If this standby letter of credit is funded, due to the current financial condition of the customer, the Bank likely will foreclose on the 
real estate securing the customer’s reimbursement obligation. This likely will result in an increase in other real estate for approximately the same amount as the 
funding.

At December 31, 2006, our management was not aware of any potential problem loans or leases that would have a material effect on loan and lease delinquency 
or loan and lease charge-offs. Loans and leases are subject to continual review and are given management’s attention whenever a problem situation appears to 
be developing.

Core Deposits — Our major source of investable funds is provided by stable core deposits consisting of all interest bearing and noninterest bearing deposits, 
excluding brokered certificates of deposit and certain certificates of deposit of $100,000 and over. In 2006, average core deposits equaled 63.27% of average 
total assets, compared to 67.60% in 2005 and 66.97% in 2004. The effective cost rate of core deposits in 2006 was 2.65%, compared to 1.96% in 2005 and 
1.59% in 2004. 

Average  demand  deposits  (noninterest  bearing  core  deposits)  decreased  10.26%  in  2006  compared  to  an  increase  of  2.17%  in  2005.  These  represented 
15.67% of total core deposits in 2006, compared to 17.21% in 2005, and 17.13% in 2004.

Purchased Funds — We use purchased funds to supplement core deposits and include certain certificates of deposit of $100,000 and over, brokered certificates
of deposit, Federal funds, securities sold under agreements to repurchase, commercial paper, and other short-term borrowings. Purchased funds are raised from 
customers seeking short-term investments and are used to manage the Bank’s interest rate sensitivity. During 2006, our reliance on purchased funds increased 
to 22.21% of average total assets from 18.55% in 2005.

Shareholders’ Equity — Average shareholders’ equity equated to 10.07% of average total assets in 2006 compared to 9.89% in 2005. Shareholders’ equity 
was 9.69% of total assets at year-end 2006, compared to 9.84% at year-end 2005. In accordance with SFAS No. 115, “Accounting for Certain Investments in 
Debt and Equity Securities,” we include unrealized gain (loss) on available-for-sale securities, net of income taxes, as accumulated other comprehensive income 
(loss) which is a component of shareholders’ equity. While regulatory capital adequacy ratios exclude unrealized gain (loss), it does impact our equity as reported 
in the audited financial statements. The unrealized loss on available-for-sale securities, net of income taxes, was $0.26 million and $3.24 million at December 31, 
2006 and 2005, respectively.

Liquidity Risk Management — The Bank’s liquidity is monitored and closely managed by the Asset/Liability Management Committee (ALCO), whose members 
are comprised of the Bank’s senior management. Asset and liability management includes the management of interest rate sensitivity and the maintenance of an 
adequate liquidity position. The purpose of interest rate sensitivity management is to stabilize net interest income during periods of changing interest rates.

t

Liquidity management is the process by which the Bank ensures that adequate liquid funds are available to meet financial commitments on a timely basis. Financial 
institutions must maintain liquidity to meet day-to-day requirements of depositors and borrowers, take advantage of market opportunities and provide a cushion 
against unforeseen needs. 

Liquidity of the Bank is derived primarily from core deposits, principal payments received on loans, the sale and maturity of investment securities, net cash provided 
by operating activities, and access to other funding sources. The most stable source of liability funded liquidity is deposit growth and retention of the core deposit 
base. The principal source of asset-funded liquidity is available-for-sale investment securities, cash and due from banks, Federal funds sold, securities purchased 
under agreements to resell, and loans and interest bearing deposits with other banks maturing within one year. Additionally, liquidity is provided by repurchase 
agreements, and the ability to borrow from the Federal Reserve Bank and Federal Home Loan Bank.

Interest  Rate  Risk  Management  —  ALCO  monitors  and  manages  the  relationship  of  earning  assets  to  interest  bearing  liabilities  and  the  responsiveness  of 
asset  yields,  interest  expense,  and  interest  margins  to  changes  in  market  interest  rates.  In  the  normal  course  of  business,  we  face  ongoing  interest  rate  risks 
and uncertainties. We occasionally utilize interest rate swaps to partially manage the primary market exposures associated with the interest rate risk related to
underlying assets, liabilities, and anticipated transactions. 

A hypothetical change in earnings was modeled by calculating an immediate 100 basis point (1.00%) change in interest rates across all maturities. This analysis 
presents the hypothetical change in earnings of those rate sensitive financial instruments and interest rate swaps which we held at December 31, 2006. The 
aggregate hypothetical decrease in pre-tax earnings was estimated to be $0.92 million on an annualized basis on all rate-sensitive financial instruments, based on a 
hypothetical increase of a 100 basis point change in interest rates. The aggregate hypothetical increase in pre-tax earnings was estimated to be $0.59 million on an 
annualized basis on all rate-sensitive financial instruments based on a hypothetical decrease of a 100 basis point change in interest rates. The earnings simulation 
model excludes the earnings dynamics related to how fee income and noninterest expense may be affected by changes in interest rates. Actual results may differ 
materially from those projected. The use of this methodology to quantify the market risk of the balance sheet should not be construed as an endorsement of its 
accuracy or the accuracy of the related assumptions. At December 31, 2006, the impact of these hypothetical fluctuations in interest rates on our derivative 
holdings was not significant, and, as such, separate disclosure is not presented.

Due to the nature of the mortgage banking business, we manage the earning assets and interest-bearing liabilities of Trustcorp on a separate basis. The predominant 
assets on Trustcorp’s balance sheet are mortgage loans held for sale, which are funded by short-term borrowings (normally less than 30 days). These borrowings 
are managed on a daily basis. We fund a portion of Trustcorp’s other borrowings for working capital.

Trustcorp manages the interest rate risk related to loan commitments by entering into contracts for future delivery of loans with outside parties. See Part II, Item 8, 
Financial Statements and Supplementary Data — Note O of the Notes to Consolidated Financial Statements.

OFF-BALANCE SHEET ARRANGEMENTS AND CONTRACTUAL OBLIGATIONS

In the ordinary course of operations, we enter into certain contractual obligations. Such obligations include the funding of operations through debt issuances as 
well as leases for premises and equipment. The following table summarizes our significant fixed, determinable, and estimated contractual obligations, by payment 
date, at December 31, 2006, except for obligations associated with short-term borrowing arrangements. Payments for borrowings do not include interest. Further 
discussion of the nature of each obligation is included in the referenced note to the consolidated financial statements.

We routinely enter into contracts for services. These contracts may require payment for services to be provided in the future and may also contain penalty clauses 
for early termination of the contract. We have made a diligent effort to account for such payments and penalties, where applicable. Additionally, where necessary, 
we have made reasonable estimates as to certain purchase obligations as of December 31, 2006. Our management has used the best information available to 
make the estimations necessary to value the related purchase obligations. Our management is not aware of any additional commitments or contingent liabilities 
which may have a material adverse impact on or liquidity or capital resources.

We also enter into derivative contracts under which we are required to either receive cash from, or pay 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 the contracts change daily as market interest rates change. 
Because the derivative liabilities recorded on the balance sheet at December 31, 2006 do not represent the amounts that may ultimately be paid under these 
contracts, these liabilities are not included in the table of contractual obligations presented above.

Assets  under  management  and  assets  under  custody  are  held  in  fiduciary  or  custodial  capacity  for  our  clients.  In  accordance  with  U.  S.  generally  accepted 
accounting principles, these assets are not included on our balance sheet.

We are also party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our clients. These financial 
instruments include commitments to extend credit and standby letters of credit. Further discussion of these commitments is included in Part II, Item 8, Financial 
Statements and Supplementary Data — Note O of the Notes to Consolidated Financial Statements.

Net income was $8.12 million for the fourth quarter of 2006, down 10.73 percent compared to the $9.10 million of net income reported for the fourth quarter 
of 2005. Diluted net income per common share for the fourth quarter of 2006 amounted to $0.36, compared to $0.39 per common share reported in the 
fourth quarter of 2005. 

Our recovery of provision for loan and lease losses was $0.10 million in the fourth quarter of 2006 compared to a recovery of provision for loan and lease losses 
of $0.72 million in the fourth quarter of 2005. Net charge-offs were $0.10 million for the fourth quarter 2006, compared to net recoveries of $0.87 million a 
year ago.

Noninterest income for the fourth quarter of 2006 was $17.69 million, a marginal increase, as compared to the fourth quarter of 2005. During the fourth quarter 
of 2006 increases in equipment rental income and trust fees were mostly offset by a decline in mortgage banking income. 

Noninterest expense for the fourth quarter of 2006 was $32.60 million an increase of 5.64 percent as compared to the fourth quarter of 2005. The increase 
in the fourth quarter of 2006 as compared to the fourth quarter of 2005 was primarily due to higher depreciation on leased equipment expense, furniture and 
equipment expense, and professional fees

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of 1st Source Corporation

We have audited management’s assessment, included in the accompanying Report of Management, that 1st Source Corporation maintained effective internal 
control over financial reporting as of December 31, 2006, based on criteria established in Internal Control—Integrated Framework issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (the COSO criteria). 1st Source Corporation’s management is responsible for maintaining effective internal 
control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on 
management’s assessment and an opinion on the effectiveness of the company’s internal control over financial reporting based on our audit.

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

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effec-
tiveness 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 1st Source Corporation maintained effective internal control over financial reporting as of December 31, 2006, is 
fairly stated, in all material respects, based on the COSO criteria.  Also, in our opinion, 1st Source Corporation maintained, in all material respects, effective internal 
control over financial reporting as of December 31, 2006, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statements of finan-
cial condition of 1st Source Corporation and subsidiaries as of December 31, 2006 and 2005, and the related consolidated statements of income, shareholders’ 
equity, and cash flow for each of the three years in the period ended December 31, 2006 and our report dated February 23, 2007 expressed an unqualified 
opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of 1st Source Corporation

We have audited the accompanying consolidated statements of financial condition of 1st Source Corporation and subsidiaries as of December 31, 2006 and 
2005, and the related consolidated statements of income, shareholders’ equity, and cash flow for each of the three years in the period ended December 31, 
2006.  These financial statements are the responsibility of the Company’s management.  Our responsibility is to express an opinion on these financial statements
based on our audits.

We conducted our audits in accordance with the standards of the Public 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 also 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, and 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 consolidated financial position of 1st Source 
Corporation and subsidiaries at December 31, 2006 and 2005, and the consolidated results of their operations and their cash flows for each of the three years 
in the period ended December 31, 2006, in conformity with U.S. generally accepted accounting principles.

As discussed in Note B to the financial statements, in 2006 the Company changed its method of accounting for stock-based compensation.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of 1st Source 
Corporation’s internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control-Integrated Framework issued by 
the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 23, 2007 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note A — Accounting Policies

The principal line of business of 1st Source and our subsidiaries is banking and closely related activities. The following is a summary of significant accounting policies 
followed in the preparation of the consolidated financial statements.

Principles of Consolidation — The financial statements consolidate 1st Source and our subsidiaries (principally the Bank and Trustcorp). All significant intercompany 
balances and transactions have been eliminated. For purposes of the parent company only financial information presented in Note T, investments in subsidiaries are 
carried at equity in our underlying net assets.

Use of Estimates in the Preparation of Financial Statements — Financial statements prepared in accordance with U. S. generally accepted accounting principles 
require our management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and 
liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from 
those estimates.

Cash Flow — For purposes of the consolidated and parent company only statements of cash flows, we consider cash and due from banks as cash and cash
equivalents. 

Securities — Securities that we have the ability and positive intent to hold to maturity are classified as investment securities held-to-maturity. Held-to-maturity 
investment securities, when present, are carried at amortized cost. We currently hold no securities classified as held-to-maturity. Securities that may be sold in 
response to, or in anticipation of, changes in interest rates and resulting prepayment risk, or for other factors, are classified as available-for-sale and are carried 
at fair value. Unrealized gains and losses on these securities are reported net of applicable taxes, as a separate component of accumulated other comprehensive 
income (loss) in shareholders’ equity. 

The fair value is determined based on quoted market prices. If quoted market prices are not available, fair value is determined based on quoted prices of similar 
instruments.  Available-for-sale  and  held-to-maturity  securities  are  reviewed  quarterly  for  possible  other-than-temporary  impairment.  The  review  includes  an 
analysis of the facts and circumstances of each individual investment such as length of time the fair value has been below cost, the expectation for that security’s 
performance, the credit worthiness of the issuer, and our intent and ability to hold the security for a time necessary to recover the amortized cost. A decline in value 
that is determined to be other-than-temporary is recorded as a loss in the Consolidated Statements of Income. 

Debt and equity securities that are purchased and held principally for the purpose of selling them in the near term are classified as trading account securities and 
are carried at fair value with unrealized gains and losses reported in earnings. At December 31, 2006, we did not have any securities classified as trading securities. 
Realized gains and losses on the sales of all securities are reported in earnings and computed using the specific identification cost basis.

Loans and Leases — Loans are stated at the principal amount outstanding, net of unamortized deferred loan origination fees and costs and net of unearned 
income. Interest income is accrued as earned based on unpaid principal balances. Origination fees and direct loan and lease origination costs are deferred and the 
net amount amortized to interest income over the estimated life of the related loan or lease. Loan commitment fees are deferred and amortized into other income 
over the commitment period. 

Direct financing leases are carried at the aggregate of lease payments plus estimated residual value of the leased property, less unearned income. Interest income 
on direct financing leases is recognized over the term of the lease to achieve a constant periodic rate of return on the outstanding investment.

The accrual of interest on loans and leases is discontinued when a loan or lease becomes contractually delinquent for 90 days, except for residential mortgage loans 
and consumer loans that are well secured and in the process of collection. Residential mortgage loans are placed in nonaccrual at the time the loan is placed in 
foreclosure. When interest accruals are discontinued, interest credited to income in the current year is reversed and interest accrued in the prior year is charged to 
the reserve for loan and lease losses. However, in some cases, management may elect to continue the accrual of interest when the net realizable value of collateral 
is sufficient to cover the principal and accrued interest. When a loan or lease is classified as nonaccrual and the future collectibility of the recorded loan or lease 
balance is doubtful, collections on interest and principal are applied as a reduction to principal outstanding.

A loan or lease is considered impaired, based on current information and events, if it is probable that we will be unable to collect the scheduled payments of 
principal or interest when due according to the contractual terms of the loan or lease agreement. Interest on impaired loans and leases, which are not classified as 
nonaccrual, is recognized on the accrual basis. Beginning January 1, 2006, we began evaluating only those loans and leases exceeding $100,000 for impairment 
in accordance with the provisions of Statement of Financial Accounting Standards No. 114, “Accounting by Creditors for Impairment of a Loan,” (SFAS No. 114) 
which requires an allowance to be established as a component of the allowance for loan and lease losses when it is probable all amounts due will not be collected 
pursuant to the contractual terms of the loan and lease and the recorded investment in the loan or lease exceeds its fair value. Prior to January 1, 2006, we did 
not have a minimum threshold in place for the purpose of evaluating impairment. 

1st Source, through our subsidiary Trustcorp, sells mortgage loans to the Government National Mortgage Association (GNMA) in the normal course of business 
and retains the servicing rights. The GNMA programs under which the loans are sold allow us to repurchase individual delinquent loans that meet certain criteria 
from the securitized loan pool. At our option, and without GNMA’s prior authorization, we may repurchase a delinquent loan for an amount equal to 100% of the 
remaining principal balance on the loan. Under SFAS No. 140, once we have the unconditional ability to repurchase a delinquent loan, we are deemed to have 
regained effective control over the loan and we are required to recognize the loan on our balance sheet and record an offsetting liability, regardless of our intent 
to repurchase the loan. At December 31, 2006 and 2005, residential real estate portfolio loans included $2.42 million and $18.09 million, respectively, of loans 
available for repurchase under the GNMA optional repurchase programs with the offsetting liability recorded within other short-term borrowings. 

Mortgage Banking Activities — Loans held for sale are primarily composed of performing one-to-four family residential mortgage loans originated for resale 
and carried at the lower of cost or fair value as determined on an aggregate basis. Fair value is determined using available secondary market prices for loans with

We recognize the rights to service mortgage loans for others as separate assets, whether the servicing rights are acquired through a separate purchase or through 
the sale of originated loans with servicing rights retained. We allocate a portion of the total cost of a mortgage loan to servicing rights based on the relative fair 
value. The fair value of the servicing rights is based on market prices, when available, or is determined by estimating the present value of future net servicing income, 
taking into consideration market loan prepayment speeds and discount rates. These assets are amortized as reductions of mortgage servicing fee income over the 
estimated servicing period in proportion to the estimated servicing income to be received. Gains and losses on the sale of mortgage servicing rights are recognized 
as noninterest income in the period in which such rights are sold.

Mortgage servicing assets are evaluated for impairment in accordance with SFAS No. 140. For purposes of impairment measurement, mortgage servicing assets 
are stratified based on the predominant risk characteristics of the underlying servicing, principally by loan type and interest rate. The fair value of each tranche 
of the servicing portfolio is estimated by calculating the present value of estimated future net servicing cash flows, taking into consideration actual and expected 
mortgage loan prepayment rates, discount rates, servicing costs, and other economic factors. If temporary impairment exists within a tranche, a valuation allowance 
is established through a charge to income equal to the amount by which the carrying value exceeds the fair value. If it is later determined all or a portion of the 
temporary impairment no longer exists for a particular tranche, the valuation allowance is reduced through a recovery of income.

Mortgage servicing assets are also reviewed for other-than-temporary impairment. Other-than-temporary impairment exists when recoverability of a recorded 
valuation allowance is determined to be remote considering historical and projected interest rates, prepayments, and loan pay-off activity. When this situation 
occurs,  the  unrecoverable  portion  of  the  valuation  allowance  is  applied  as  a  direct  write-down  to  the  carrying  value  of  the  mortgage  servicing  asset.  Unlike 
a  valuation  allowance,  a  direct  write-down  permanently  reduces  the  carrying  value  of  the  mortgage  servicing  asset  and  the  valuation  allowance,  precluding 
subsequent recoveries.

As part of mortgage banking operations, we enter into commitments to purchase or originate loans whereby the interest rate on these loans is determined prior to 
funding (“rate lock commitments”). Similar to loans held for sale, the fair value of rate lock commitments is subject to change primarily due to changes in interest 
rates. Under our risk management policy, these fair values are hedged primarily by selling forward contracts on agency securities. The rate lock commitments on 
mortgage loans intended to be sold and the related hedging instruments are recorded at fair value with changes in fair value recorded in current earnings. The
fair value of rate lock commitments is determined using current secondary market prices for underlying loans with similar coupons, maturity and credit quality, 
subject to the anticipated loan funding probability, or fallout factor. The benefit of servicing rights inherent in the loans underlying the rate lock commitments is not 
recognized until these loans are funded and sold.

Reserve for Loan and Lease Losses — The reserve for loan and lease losses is maintained at a level believed to be adequate by management to absorb probable 
losses inherent in the loan and lease portfolio. The determination of the reserve requires significant judgment reflecting management’s best estimate of probable 
loan and lease losses related to specifically identified loans and leases as well as probable losses in the remainder of the various loan and lease portfolios. The 
methodology for assessing the appropriateness of the reserve consists of several key elements, which include: specific reserves for identified special attention 
loans and leases (classified loans and leases and internal watch list credits), percentage allocations for special attention loans and leases without specific reserves, 
formula reserves for each business lending division portfolio including a higher percentage reserve allocation for special attention loans and leases without a specific 
reserve and reserves for pooled homogenous loans and leases. Management’s evaluation is based upon a continuing review of these portfolios, estimates of future 
customer performance, collateral values and disposition and forecasts of economic and geopolitical events, all of which are subject to judgment and will change.

Specific reserves are established for certain business and specialty finance credits based on a regular analysis of special attention loans and leases. This analysis 
is performed by the Credit Policy Committee, the Loan Review Department, Credit Administration, and the Loan Workout Departments. The specific reserves are 
based on an analysis of underlying collateral values, cash flow considerations and, if applicable, guarantor capacity.

The formula reserves determined for each business lending division portfolio are calculated quarterly by applying loss factors to outstanding loans and leases
and  certain  unfunded  commitments  based  upon  a  review  of  historical  loss  experience  and  qualitative  factors,  which  include  but  are  not  limited  to,  economic 
trends, current market risk assessment by industry, recent loss experience in particular segments of the portfolios, movement in equipment values collateralizing 
specialized industry portfolios, concentrations of credit, delinquencies, trends in volume, experience and depth of relationship managers and division management, 
and the effects of changes in lending policies and practices, including changes in quality of the loan and lease origination, servicing and risk management processes.
Special attention loans and leases without specific reserves receive a higher percentage allocation ratio than credits not considered special attention.

Pooled loans and leases are smaller credits and are homogenous in nature, such as consumer credits and residential mortgages. Pooled loan and lease loss 
reserves are based on historical net charge-offs, adjusted for delinquencies, the effects of lending practices and programs and current economic conditions, and 
projected trends in the geographic markets which we serve.

A comprehensive analysis of the reserve is performed by management on a quarterly basis. Although management determines the amount of each element of 
the reserve separately and relies on this process as an important credit management tool, the entire reserve is available for the entire loan and lease portfolio. The 
actual amount of losses incurred can vary significantly from the estimated amounts both positively and negatively. Management’s methodology includes several 
factors intended to minimize the difference between estimated and actual losses. These factors allow management to adjust our estimate of losses based on the 
most recent information available.

Loans and leases, which are deemed uncollectible, are charged off and deducted from the reserve, while recoveries of amounts previously charged off are credited 
to the reserve. A (recovery of) provision for loan and lease losses is credited or charged to operations based on management’s periodic evaluation of the factors 
previously mentioned, as well as other pertinent factors.

Equipment Owned Under Operating Leases — We finance various types of construction equipment, medium and heavy duty trucks, and automobiles under 
leases classified as operating leases. Revenue consists of the contractual lease payments and is recognized on a straight-line basis over the lease term. Lease terms 
range from three to seven years. Leased assets are being depreciated on a straight-line method over the lease term to the estimate of the equipment’s fair market 
value at lease termination, also referred to as “residual” value. These residual values are reviewed periodically to ensure the recorded amount does not exceed 
the fair market value at the lease termination.

42 (cid:127) SRCE 

2006 Form 10-K

Other  Real  Estate —  Other  real  estate  acquired  through  partial  or  total  satisfaction  of  nonperforming  loans  is  included  in  other  assets  and  recorded  at  the 
estimated fair value less anticipated selling costs based upon the property’s appraised value at the date of transfer, with any difference between the fair value of 
the property less cost to sell, and the carrying value of the loan charged to the reserve for loan losses. Subsequent changes in value are reported as adjustments to 
the carrying amount and are recorded in noninterest expense on the income statement. Gains or losses not previously recognized resulting from the sale of other 
real estate are recognized on the date of sale. As of December 31, 2006 and 2005, other real estate had carrying values of $0.80 million and $0.96 million, 
respectively.

Repossessed Assets — Repossessed assets may include fixtures and equipment, inventory and receivables, and aircraft, construction equipment, and vehicles 
acquired through foreclosure or in lieu of foreclosure from our business banking activities and our specialty finance activities. Repossessed assets are included 
in other assets at the lower of cost or fair value of the equipment or vehicle. We estimate fair value based on the best estimate of an orderly liquidation value. 
Valuation resources typically include vehicle and equipment dealers, valuation guides, and other third parties, including appraisers. At the time of foreclosure, the 
recorded amount of the loan or lease is written down, if necessary, to the fair value of the equipment or vehicle by a charge to the reserve for loan and lease 
losses. Subsequent write-downs are included in noninterest expense. Gains or losses not previously recognized resulting from the sale of repossessed assets are 
recognized on the date of sale. Repossessed assets totaled $0.97 million and $4.28 million, as of December 31, 2006 and 2005, respectively.

Premises  and  Equipment  —  Premises  and  equipment  are  stated  at  cost,  less  accumulated  depreciation  and  amortization.  The  provision  for  depreciation  is 
computed by the straight-line method, primarily with useful lives ranging from three to 31.5 years. Maintenance and repairs are charged to expense as incurred, 
while improvements, which extend the useful life, are capitalized and depreciated over the estimated remaining life.

Long-lived  depreciable  assets  are  evaluated  periodically  for  impairment  when  events  or  changes  in  circumstances  indicate  the  carrying  amount  may  not  be 
recoverable. Impairment exists when the expected undiscounted future cash flows of a long-lived asset are less than its carrying value. In that event, we recognize 
a loss in the amount of the difference between the carrying amount and the estimated fair value of the asset based on a quoted market price, if applicable, or a 
discounted cash flow analysis. Impairment losses are recorded in other noninterest expense in the income statement.

Goodwill and Intangibles — Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets 
represent purchased assets that also lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the 
asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Goodwill is reviewed at least annually for 
impairment. Intangible assets that have finite lives continue to be amortized over their estimated useful lives and also continue to be subject to impairment testing. 
All of our other intangible assets have finite lives and are amortized on a straight-line basis over varying periods not exceeding seven years. We performed the 
required annual impairment test of goodwill during the first quarter of 2006 and determined that no impairment exists.

Venture Capital Investment — We account for our investments in venture capital partnerships on the equity method based upon the guidance included in EITF 
D-46. The venture capital partnerships which we have investments in, account for their investments at fair value pursuant to the guidance in the AICPA Investment 
Company Guide. As a result, our investments in these venture capital partnerships reflect the underlying fair value of the partnerships’ investments. We account for 
our investments in venture capital partnerships that are owned three percent and greater under this method. We account for our investments in venture capital 
partnerships that are owned less than three percent at the lower of cost or market. Venture capital investments in partnerships are included in other assets on the 
balance sheet. The balances as of December 31, 2006 and 2005 were $2.31 million and $2.72 million, respectively.

Short-Term Borrowings — Our short-term borrowings consist of Federal funds purchased, securities sold under agreement to repurchase, commercial paper, U.S. 
Treasury demand notes, Federal Home Loan Bank notes, and borrowings from non-affiliated banks. Federal funds purchased, securities sold under agreements to 
repurchase, and other short-term borrowings mature within one to 365 days of the transaction date. Commercial paper matures within seven to 270 days. Other 
short-term borrowings on the balance sheet include our liability related to mortgage loans available for repurchase under GNMA optional repurchase programs. 

Securities purchased under agreements to resell and securities sold under agreements to repurchase are treated as collateralized financing transactions and are 
recorded at the amounts at which the securities were acquired or sold plus accrued interest. The fair value of collateral either received from or provided to a third 
party is continually monitored and additional collateral obtained or requested to be returned to us as deemed appropriate.

Trust Fees — Trust fees are recognized on the accrual basis.

Income Taxes — 1st Source and our subsidiaries file a consolidated Federal income tax return. The provision for incomes taxes is based upon income in the 
financial statements, rather than amounts reported on our income tax return.

Deferred tax assets and liabilities are recognized for the 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 expected to apply to taxable 
income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in 
tax rates is recognized as income or expense in the period that includes the enactment date.

Net Income Per Common Share — Net income per common share is computed in accordance with SFAS No. 128, “Earnings per Share.”  Basic earnings per 
share is computed by dividing net income by the weighted-average number of shares of common stock outstanding, which were as follows (in thousands): 2006, 
22,537;  2005,  22,755;  and  2004,  22,780.  Diluted  earnings  per  share  is  computed  by  dividing  net  income  by  the  weighted-average  number  of  shares  of 
common stock outstanding, plus the dilutive effect of outstanding stock options. The weighted-average number of common shares, increased for the dilutive effect 
of stock options, used in the computation of diluted earnings per share were as follows (in thousands): 2006, 22,830; 2005, 23,053; and 2004, 23,083.

Stock-Based Employee Compensation — Prior to January 1, 2006, employee compensation expense under stock option plans was reported only if options were 
granted below market price at grant date in accordance with the intrinsic value method of Accounting Principles Board Opinion No. 25 (APB No. 25), “Accounting 
for Stock Issued to Employees,” and related interpretations. We generally would have recognized compensation expense for stock options only if we granted options 
with a discounted exercise price or modified the terms of previously issued options, and would have recognized the related compensation expense ratably over
the associated service period, which was generally the option vesting term. Because the exercise price of the employee stock options granted always equaled the 
market price of the underlying stock on the date of grant, no compensation expense was recognized on options granted. 

43 (cid:127) SRCE 

2006 Form 10-K

We adopted the provisions of SFAS No. 123(R) on January 1, 2006. SFAS No. 123(R) eliminates the ability to account for stock-based compensation using 
APB No. 25 and requires that such transactions be recognized as compensation cost in the income statement based on their fair values on the measurement 
date, which, for our purposes, is the date of grant. We transitioned to fair-value based accounting for stock-based compensation using the modified prospective 
application and, therefore, have not restated results for prior periods. This transition method applies to new awards for service periods beginning on or after January 
1, 2006, and to awards modified, repurchased, or cancelled after January 1, 2006. Additionally, compensation cost for the portion of awards for which the
requisite service has not been rendered (generally referring to non-vested award) which were granted prior to January 1, 2006 will be recognized as the remaining 
requisite service is rendered during the period of and/or the periods after the adoption of SFAS No. 123(R).

SFAS No. 123(R), requires pro forma disclosures of net income and earnings per share for all periods prior to the adoption of the fair value accounting method for 
stock-based employee compensation. The pro forma disclosures presented in Note K — Employee Stock Benefit Plans use the fair value method of SFAS 123 to 
measure compensation expense for stock-based employee compensation plans for years prior to 2006.

Segment Information — In our management’s opinion, 1st Source has two principal business segments, namely: commercial banking (conducted through its 
wholly-owned subsidiary, 1st Source Bank) and mortgage banking (conducted through its wholly-owned subsidiary, Trustcorp). While our chief decision makers 
monitor the revenue streams of various products and services, the identifiable segments’ operations are managed and financial performance is evaluated on a 
company-wide basis. Accordingly, all of our financial service operations are considered by management to be aggregated in one reportable operating segment. 

Derivative Financial Instruments — We occasionally enter into derivative financial instruments as part of our interest rate risk management strategies. These
derivative financial instruments consist primarily of interest rate swaps. Under the guidance of SFAS No. 133, “Accounting for Derivative Instruments and Hedging 
Activities,” as amended, all derivative instruments are recorded on the balance sheet, as either an asset or liability, at their fair value. The accounting for the gain
or loss resulting from the change in fair value depends on the intended use of the derivative. For a derivative used to hedge changes in fair value of a recognized 
asset or liability, or an unrecognized firm commitment, the gain or loss on the derivative will be recognized in earnings together with the offsetting loss or gain on 
the hedged item. This results in an earnings impact only to the extent that the hedge is ineffective in achieving offsetting changes in fair value. If it is determined 
that the derivative instrument is not highly effective as a hedge, hedge accounting is discontinued and the adjustment to fair value of the derivative instrument is 
recorded in earnings. For a derivative used to hedge changes in cash flows associated with forecasted transactions, the gain or loss on the effective portion of the 
derivative will be deferred, and reported as accumulated other comprehensive income, a component of shareholders’ equity, until such time the hedged transaction 
affects earnings. For derivative instruments not accounted for as hedges, changes in fair value are recognized in noninterest income/expense. Deferred gains and 
losses from derivatives that are terminated are amortized over the shorter of the original remaining term of the derivative or the remaining life of the underlying 
asset or liability. 

Note B — Recent Accounting Pronouncements

Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements: In September 2006, the U.S. 
Securities and Exchange Commission (SEC) staff issued Staff Accounting Bulletin No. 108 (SAB No. 108), “Considering the Effects of Prior Year Misstatements 
when  Quantifying  Misstatements  in  Current  Year  Financial  Statements.”  SAB  No.  108  eliminates  the  diversity  of  practice  surrounding  how  public  companies 
quantify  financial  statement  misstatements.  It  establishes  an  approach  that  requires  quantification  of  financial  statement  misstatements  based  on  the  effects 
of the misstatements on each of the company’s financial statements and the related financial statement disclosures. SAB No. 108 must be applied to annual 
financial statements for their first fiscal year ending after November 15, 2006. SAB No. 108 did not have a material impact on our financial condition or results 
of operations. 

Fair Value Measurements: In September 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 157, 
“Fair Value Measurements” (SFAS No. 157). This standard clarifies the principle that fair value should be based on the assumptions that market participants would 
use when pricing an asset or liability. Additionally, it establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. We have 
not yet determined the impact that the implementation of SFAS No. 157 will have on our results of operations or financial condition. SFAS No. 157 is effective for 
financial statements issued for fiscal years beginning after November 15, 2007.

Employers’  Accounting  for  Defined  Benefit  Pension  and  Other  Postretirement  Plans: In  September  2006,  the  FASB  issued  SFAS  No. 158,  “Employers 
Accounting  for  Defined  Benefit  Pension  and  Other  Postretirement  Plans  an  amendment  of  FASB  Statements  No. 87,  88,  106,  and  132(R).”   This  standard 
requires employers to recognize the underfunded or overfunded status of a defined benefit postretirement plan as an asset or liability in its statement of financial 
position and to recognize changes in the funded status in the year in which the changes occur through accumulated other comprehensive income. Additionally, 
SFAS  No.  158  requires  employers  to  measure  the  funded  status  of  a  plan  as  of  the  date  of  its  year-end  statement  of  financial  position.   The  new  reporting 
requirements and related new footnote disclosure rules of SFAS No. 158 are effective for fiscal years ending after December 15, 2006. SFAS No. 158 did not 
have a material impact on our financial condition or results of operation. Our accrued postretirement benefit cost was not material at December 31, 2006, 2005, 
and 2004; therefore, additional disclosure is not provided. The new measurement date requirement applies for fiscal years ending after December 15, 2008. We 
do not expect the measurement date of this statement to have a material impact on our financial condition or results of operations.

Accounting for Uncertainty in Income Taxes: In July 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48 (FIN No. 48), 
“Accounting for Uncertainty in Income Taxes an interpretation of FASB Statement No. 109” which clarifies the accounting for uncertainty in tax positions. FIN No. 
48 requires that we recognize in our financial statements, the impact of a tax position, if that position is more likely than not of being sustained on audit, based on 
the technical merits of the position. The provisions of FIN No. 48 are effective as of the beginning of our 2007 fiscal year, with the cumulative effect of the change 
in accounting principle recorded as an adjustment to opening retained earnings. We do not expect the provisions of this interpretation to have a material impact on 
our financial condition or results of operations.

Share-Based Payment: SFAS No. 123(R), “Share-Based Payment,” establishes standards for the accounting for transactions in which an entity (i) exchanges its 
equity instruments for goods or services, or (ii) incurs liabilities in exchange for goods or services that are based on the fair value of the entity’s equity instruments 
or that may be settled by the issuance of the equity instruments. SFAS No. 123(R) eliminates the ability to account for stock-based compensation using APB No. 
25 and requires that such transactions be recognized as compensation cost in the income statement based on their fair values on the measurement date, which 
is generally the date of the grant. We adopted the provisions SFAS No.123(R) on January 1, 2006. Details related to the adoption of SFAS No.123(R) and the 
impact on our financial statements is more fully discussed in Note K — Employee Stock Benefit Plans.

44 (cid:127) SRCE 

2006 Form 10-K

Accounting for Servicing of Financial Assets: In March 2006, the FASB issued SFAS No. 156, “Accounting for Servicing of Financial Assets — an amendment 
of FASB Statement No. 140.” SFAS No.156 requires an entity to recognize a servicing asset or servicing liability each time it undertakes an obligation to service a 
financial asset by entering into a servicing contract in specific situations. Additionally, the servicing asset or servicing liability shall be initially measured at fair value; 
however, an entity may elect the “amortization method” or “fair value method” for subsequent balance sheet reporting periods. SFAS No.156 is effective as of an 
entity’s first fiscal year beginning after September 15, 2006. Early adoption is permitted as of the beginning of an entity’s fiscal year, provided the entity has not yet 
issued financial statements, including interim financial statements, for any period of that fiscal year. Our adoption of this statement in 2006 did not have a material 
impact on our financial condition, results of operations, or cash flows.

Accounting for Certain Hybrid Financial Instruments: In February 2006, the FASB issued SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments 
—  an  amendment  of  FASB  Statements  No.  133  and  140.” SFAS  No.  155  simplifies  accounting  for  certain  hybrid  instruments  currently  governed  by  SFAS 
No. 133 “Accounting for Derivative Instruments and Hedging Activities,” by allowing fair value remeasurement of hybrid instruments that contain an embedded 
derivative that otherwise would require bifurcation. SFAS No. 155 also eliminates the guidance in SFAS No.133 Implementation Issue No. D1, “Application of 
Statement 133 to Beneficial Interests in Securitized Financial Assets,” which provides such beneficial interests are not subject to SFAS No.133. SFAS No. 155 
amends SFAS No. 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities — a Replacement of FASB Statement No. 
125,” by eliminating the restriction on passive derivative instruments that a qualifying special-purpose entity may hold. This statement is effective for financial 
instruments acquired or issued after the beginning of our fiscal year 2007. We do not expect the adoption of this statement to have a material impact on our 
financial condition, results of operations or cash flows.

Reclassifications — Certain amounts in the prior period consolidated financial statements have been reclassified to conform with the current year presentation. 
These reclassifications had no effect on total assets, shareholders’ equity or net income as previously reported. We declared a 10% stock dividend on July 27, 
2006; therefore, all share and per share information has been adjusted accordingly.

At December 31, 2006, we did not believe any individual unrealized loss represented other-than-temporary impairment. The unrealized losses were primarily 
attributable to changes in interest rates. We have both the intent and the ability to hold these securities for a time necessary to recover the amortized cost. 

At December 31, 2006 and 2005, investment securities with carrying values of $286.60 million and $318.51 million, respectively, were pledged as collateral to
secure government deposits, security repurchase agreements, and for other purposes.

Note D — Loans and Lease Financings

Total loans and leases outstanding were recorded net of unearned income and deferred loan fees and costs at December 31, 2006 and 2005, and totaled $2.70 
billion and $2.46 billion, respectively. At December 31, 2006 and 2005, net deferred loan and lease costs were $6.46 million and $5.66 million, respectively.

The loan and lease portfolio includes direct financing leases, which are included in auto, light truck and environmental equipment, medium and heavy duty truck, 
aircraft financing, and construction equipment financing on the consolidated balance sheet.

At December 31, 2006, the minimum future lease payments receivable for each of the years 2007 through 2011 were $42.52 million, $34.24 million, $26.92 
million, $19.43 million, and $11.17 million, respectively.

We and our subsidiaries have extended, and expect to extend in the future, loans to officers, directors, and principal holders of equity securities of 1st Source and 
our subsidiaries and to our associates. In the opinion of management, these loans are made on substantially the same terms, including interest rates and collateral, 
as those prevailing at the time for comparable transactions with other parties and are consistent with sound banking practices and within applicable regulatory and 
lending limitations. The aggregate dollar amounts of these loans were $8.99 million and $17.48 million at December 31, 2006 and 2005, respectively. During 
2006, $9.89 million of new loans were made and repayments and other reductions totaled $18.38 million.

At December 31, 2006 and 2005, nonaccrual and restructured loans and leases, substantially all of which are collateralized, were $15.58 million and $16.55 
million, respectively. Interest income for the years ended December 31, 2006, 2005, and 2004, would have increased by approximately $1.28 million, $1.38 
million, and $2.27 million, respectively, if these loans and leases had earned interest at their full contract rate.

As of December 31, 2006 and 2005, impaired loans and leases totaled $12.32 million and $16.87 million, respectively, of which $3.73 million and $3.07 
million had corresponding specific reserves for loan and lease losses totaling $0.49 million and $2.52 million, respectively. The remaining balances of impaired 
loans and leases had no specific reserves for loan and lease losses associated with them. As of December 31, 2006, a total of $10.72 million of the impaired 
loans and leases were nonaccrual loans and leases. For 2006, 2005, and 2004 the average recorded investment in impaired loans and leases was $11.39 
million, $27.65 million and $51.14 million, respectively, and interest income recognized on impaired loans and leases totaled $0.56 million, $1.01 million, and 
$2.55 million, respectively.

Note F — Operating Leases

We finance various types of construction equipment, medium and heavy duty trucks, automobiles, and miscellaneous production equipment under leases principally 
classified as operating leases. These operating leases are reported at cost, net of accumulated depreciation. These operating lease arrangements require the 
lessee to make a fixed monthly rental payment over a specified lease term, typically from three to seven years. These operating lease assets are recorded net of 
accumulated depreciation in the consolidated balance sheet. Rental income is earned on the operating lease assets and reported as noninterest income. These 
operating lease assets are depreciated over the term of the lease to the estimated fair value of the asset at the end of the lease. The depreciation of these operating 
lease assets is reported as a component of noninterest expense. At the end of the lease, the operating lease asset is either purchased by the lessee or returned 
to us. 

Operating lease equipment at December 31, 2006 and 2005, was $76.31 million and $58.25 million, respectively, net of accumulated depreciation of $27.76 
million and $29.79 million, respectively. Depreciable lives for operating lease equipment generally range from three to seven years.

The minimum future lease rental payments due from clients on operating lease equipment at December 31, 2006, totaled $62.50 million, of which $18.47 
million is due in 2007, $16.41 million in 2008, $12.67 million in 2009, $8.76 million in 2010, $4.28 million in 2011, $1.62 million in 2012, and $0.29 million 
in 2013. Depreciation expense related to operating lease equipment for the year ended December 31, 2006 was $14.96 million.

Note H — Mortgage Servicing Assets

The unpaid principal balance of residential mortgage loans serviced for third parties was $0.65 billion at December 31, 2006, compared to $1.54 billion at 
December 31, 2005, and $1.91 billion at December 31, 2004.

Mortgage  servicing  assets  are  evaluated  for  impairment  and  a  valuation  allowance  is  established  through  a  charge  to  income  when  the  carrying  value  of  the 
mortgage servicing assets exceeds the fair value and the impairment is determined to be temporary. Other-than-temporary impairment is recognized when the 
recoverability of a recorded valuation allowance is determined to be remote taking into consideration historical and projected interest rates and loan pay-off activity. 
When this situation occurs, the unrecoverable portion of the valuation allowance is applied as a direct write-down to the carrying value of the mortgage servicing 
asset. Unlike a valuation allowance, a direct write-down permanently reduces the carrying value of the mortgage servicing asset and the valuation allowance,
precluding  subsequent  recoveries.  During  2006,  management  determined  that  it  was  not  necessary  to  permanently  write-down  any  previously  established 
valuation allowance. At December 31, 2006, the fair value of mortgage servicing assets exceeded the carrying value reported in the consolidated balance sheet 
by $3.05 million. This difference represents increases in the fair value of certain mortgage servicing assets accounted for under SFAS No. 140 that could not be 
recorded above cost basis. 

The key economic assumptions used to estimate the value of the mortgage servicing rights as of December 31 follow:

Expected weighted-average life (in years)  
Weighted-average constant prepayment rate (CPR)  
Weighted-average discount rate  

2006

2005

Funds held in trust at 1st Source for the payment of principal, interest, taxes and insurance premiums applicable to mortgage loans being serviced for others, were 
approximately $7.67 million and $21.08 million at December 31, 2006 and December 31, 2005, respectively.

Note I — Intangible Assets and Goodwill

At December 31, 2006, intangible assets consisted of goodwill of $18.85 million and other intangible assets of $0.57 million, net of accumulated amortization of 
$12.34 million. At December 31, 2005, intangible assets consisted of goodwill of $18.85 million and other intangible assets of $2.53 million, net of accumulated 
amortization  of  $10.43  million.  Intangible  asset  amortization  was  $1.91  million,  $2.66  million,  and  $2.63  million  for  2006,  2005,  and  2004,  respectively. 
Amortization on other intangible assets is expected to total $0.20 million, $0.10 million, $0.10 million, $0.09 million, and $0.07 million in 2007, 2008, 2009, 
2010, and 2011, respectively.

$15,394; $10,396; $280; and $201.

At December 31, 2006, the $10.00 million term loan bore a fixed interest rate of 4.76%. Interest is payable quarterly with principal due at the October 31, 
2007, maturity. The Term Loan Agreement contains, among other provisions, certain covenants relating to existence and mergers, capital structure, and financial 
requirements.

At December 31, 2006, the Federal Home Loan Bank borrowings represented a source of funding for certain residential mortgage activities and consisted of eight 
fixed rate notes with maturities ranging from 2008 to 2022. These notes were collateralized by $35.14 million of certain real estate loans. 

Mandatorily redeemable securities as of December 31, 2006, of $6.18 million reflected the “book value” shares under the 1st Source Executive Incentive Plan. 
See Note K — Employee Stock Benefit Plans for additional information. Dividends paid on these shares and increases in book value per share are recorded as other 
interest expense. Total interest expense recorded for 2006, 2005, and 2004 was $0.66 million, $0.54 million, and $0.38 million, respectively.

Note K — Employee Stock Benefit Plans

As of December 31, 2006, we had five stock-based employee compensation plans. These plans include two stock option plans, namely, the 1992 Stock Option 
Plan, and the 2001 Stock Option Plan; two executive stock award plans, namely, the Executive Incentive Plan, and the Restricted Stock Award Plan, and the 
Employee Stock Purchase Plan. These stock-based employee compensation plans were established to help retain and motivate key employees. All of the plans 
have been approved by the shareholders of 1st Source Corporation. The Executive Compensation and Human Resources Committee (the “Committee”) of the 
1st Source Corporation Board of Directors has sole authority to select the employees, establish the awards to be issued, and approve the terms and conditions of 
each award under the stock-based compensation plans.

A combined summary of activity regarding our active stock option plans and executive stock award plans is presented in the following table.

Stock Option Plans — Our incentive stock option plans include the 1992 Stock Option Plan (the “1992 Plan”) and the 2001 Stock Option Plan (the “2001
Plan”). As of December 31, 2006, there were 421,936 stock options remaining exercisable under the 1992 Plan, all of which will expire in January 2011. We 
have not issued any awards from the 1992 Plan since 2001, as the 1992 Plan was terminated, except for outstanding options, after the 2001 Plan was approved 
by the shareholders. Options under the 2001 Plan vest in one to eight years from date of grant. As of December 31, 2006, there were 67,539 stock options 
available for issuance upon exercise and 2,122,618 available for issuance under the 2001 Plan. 

Each award from all plans is evidenced by an award agreement that specifies the option price, the duration of the option, the number of shares to which the option 
pertains, and such other provisions as the Committee determines. The option price is equal to the fair market value of a share of 1st Source Corporation’s common 
stock on the date of grant. Options granted expire at such time as the Committee determines at the date of grant and in no event does the exercise period exceed 
a maximum of ten years, except for reload options under the 2001 Plan, which are given the remaining term of the original grant. Upon merger, consolidation, or 
other corporate consolidation in which 1st Source Corporation is not the surviving corporation, as defined in the plans, all outstanding options immediately vest.

Proceeds from stock option exercises totaled $0.91 million in 2006, $0.34 million in 2005, and $1.74 million in 2004. During 2006, 71,062 shares were 
issued in connection with stock option exercises from available treasury shares. All shares issued in connection with stock option exercises and non-vested stock 
awards are issued from available treasury stock.

The total intrinsic value of outstanding stock options and outstanding exercisable stock options was $2.98 million and $2.64 million at December 31, 2006. The 
total intrinsic value of stock options exercised was $0.96 million in 2006, $0.29 million in 2005, and $3.36 million in 2004. The total fair value of share awards 
vested was $0.67 million during 2006 $0.46 million in 2005, and $0.31 million in 2004.

As stated in Note A — Accounting Policies, effective January 1, 2006, we adopted the fair value recognition provisions of SFAS No. 123(R). SFAS 123(R) requires 
that stock-based compensation to employees be recognized as compensation cost in the income statement based on their fair values on the measurement date, 
which, for 1st Source, is the date of grant. Stock-based compensation expense is recognized ratably over the requisite service period for all awards. As a result 
of applying the provisions of SFAS 123(R) during 2006, we recognized additional stock-based compensation expense related to stock options of $61,606 (not 
subject to tax). The increase in stock-based compensation expense related to stock options had an immaterial impact on basic or diluted earnings per share during 
2006. Cash flows from financing activities for 2006 were not affected by stock option exercises during 2006.

The fair value of each option on the date of grant was estimated using the Black-Scholes option pricing model. Expected volatility is based on the historical volatility 
estimated over a period of at least equal to the estimated term of the options. In estimating the fair value of stock options under the Black-Scholes valuation 
model, separate groups of employees that have similar historical exercise behavior are considered separately. The expected term of the options granted is derived 
based on past experience and represents the period of time that options granted are expected to be outstanding. The following weighted-average assumptions 
were used in the option pricing model for options granted in 2006 (no options were granted in 2004 or 2005): a risk-free interest rate of 4.87%; an expected 
dividend yield of 2.02%; an expected volatility factor of 35.73%; and an expected option life of 5.23 years. The weighted-average grant date per share fair value 
of options granted in 2006 was $9.75.

The following pro forma information presents net income and earnings per share for 2005 and 2004 as if the fair value method of SFAS No. 123 had been used 
to measure compensation cost for the stock option plans.

Stock Award Plans — Our incentive stock award plans include the Executive Incentive Plan (EIP) and the Restricted Stock Award Plan (RSAP). The EIP is also 
administered by the Committee. Awards under the EIP include “book value” shares and “market value” shares of common stock. These shares are awarded annually 
based on weighted performance criteria and generally vest over a period of five years. The EIP book value shares may only be sold to 1st Source and such sale is 
mandatory in the event of death, retirement, disability, or termination of employment. The RSAP is designed for key employees. Awards under the RSAP are made 
to employees recommended by the Chief Executive Officer and approved by the Committee. Shares granted under the RSAP vest over a five to ten-year period 
and vesting is based upon meeting various criteria, including continued employment with 1st Source. 

Stock-based compensation expense totaled $0.41 million in 2006, $4.66 million in 2005, and $2.26 million in 2004. The total income tax benefit recognized 
in the accompanying consolidated statements of income related to stock-based compensation was $0.16 million in 2006, $1.79 million in 2005, and $0.86 
million in 2004. Unrecognized stock-based compensation expense related to stock options totaled $88,345 at December 31, 2006. At such date, the weighted-
average period over which this unrecognized expense was expected to be recognized was 2.8 years. Unrecognized stock-based compensation expense related to 
non-vested stock awards was $276,970 at December 31, 2006. At such date, the weighted-average period over which this unrecognized expense was expected 
to be recognized was 5.34 years.

The fair value of non-vested stock awards for the purposes of recognizing stock-based compensation expense is market price of the stock on the measurement 
date, which, for our purposes is the date of the award.

Employee Stock Purchase Plan — We offer an Employee Stock Purchase Plan (ESPP), for substantially all employees with at least two years of service on the 
effective date of an offering under the plan. Eligible employees may elect to purchase any dollar amount of stock, so long as such amount does not exceed 25% of 
their base rate of pay and the aggregate stock accrual rate for all offerings does not exceed $25,000 in any calendar year. The purchase price for shares offered is 
the lower of the closing market bid price for the offering date or the average market bid price for the five business days preceding the offering date. The purchase 
price and discount to the actual market closing price on the offering date for the 2006, 2005, and 2004 offerings were $25.70 (3.45%), $21.84 (2.02%), and 
$22.38 (3.69%), respectively. Payment for the stock is made through payroll deductions over the offering period, and employees may discontinue the deductions 
at any time and exercise the option or take the funds out of the program. The most recent offering began June 1, 2006 and runs through June 2, 2008, with 
$282,136 in stock value to be purchased at $25.70 per share. The fair value of the employees’ purchase rights for the 2006, 2005, and 2004 offerings was 
estimated using the Black-Scholes model. The following assumptions were used in the model in each of the last three years: a risk-free interest rate of 5.04% for 
2006; 3.40% for 2005; and 2.52% for 2004; an expected dividend yield of 2.02% for 2006; 2.17% for 2005; and 1.66% for 2004; an expected volatility 
factor of 18.77% for 2006; 27.49% for 2005; and 44.20% for 2004; and an expected life of 2.0 years for 2006, 2005, and 2004. The fair value for shares 
offered in 2006, 2005, and 2004 was $4.28, $3.44, and $5.81, respectively.

Note L — Subordinated Notes

As of December 31, 2006, we sponsored three trusts, 1st Source Capital Trust II, III and IV (Capital Trusts) of which 100% of the common equity is owned by 
1st Source. The Capital Trusts were formed for the purpose of issuing corporation-obligated mandatorily redeemable capital securities (the capital securities) to 
third-party investors and investing the proceeds from the sale of the capital securities solely in junior subordinated debt securities of 1st Source (the subordinated 
notes). The subordinated notes held by each Capital Trust are the sole assets of that Capital Trust. 

Distributions on the capital securities issued by Capital Trust II, III and IV are payable quarterly at a rate per annum equal to the interest rate being earned by the 
Capital Trust on the subordinated notes held by that Capital Trust. The capital securities are subject to mandatory redemption, in whole or in part, upon repayment 
of the subordinated notes. We have entered into agreements which, taken collectively, fully and unconditionally guarantee the capital securities subject to the terms 
of each of the guarantees. 

The capital securities held by the Capital Trusts qualify as Tier 1 capital under Federal Reserve Board guidelines. On March 1, 2005, the Federal Reserve issued 
rules that retain Tier 1 capital treatment for trust preferred securities but with stricter limits. Under the final rules, after a five-year transition period, the aggregate 
amount of trust preferred securities and certain other capital elements will retain its current limit of 25% of Tier 1 capital elements, net of goodwill. The amount 
of trust preferred securities and certain other elements in excess of the limit could be included in Tier 2 capital, subject to restrictions. These new rules have no 
impact on our Tier 1 capital.

The subordinated notes are summarized as follows, at December 31, 2006:

2002 issuance interest rate is fixed at 6.95% until November 15, 2007, at which time it will become floating at an interest rate equal to LIBOR, plus 3.35%.

Note M — Employee Benefit Plans 

Effective October 1, 2006, we amended the 1st Source Corporation Employees’ Profit Sharing Plan and Trust, which was renamed the 1st Source Corporation 
Employee Stock Ownership and Profit Sharing Plan (as amended, the “Plan”). The Plan includes an employee stock ownership component, which is designed to 
invest in and hold 1st Source common stock, and a 401(k) plan component, which holds all Plan assets not invested in 1st Source common stock. The Plan now
also includes a number of new features that encourage diversification of investments with more opportunities to change investment elections and contribution 
levels.

51 (cid:127) SRCE

2006 Form 10-K

 
  
Employees are eligible to participate in the Plan on the first day of employment. After one year and 1,000 hours of service worked, we are required under the 
401(k) component of the Plan to match dollar for dollar participant contributions up to 4% of compensation, plus 50 cents per dollar of the next 2% deferrals. We 
will also contribute to the Plan an amount designated as a fixed profit sharing contribution. The amount of fixed profit sharing contribution is equal to two percent 
of compensation. Additionally, each year we may, in our sole discretion, make additional contributions to the 401(k) component of the Plan. As of December 31, 
2006, there were 1,312,203 shares of 1st Source Corporation common stock held in relation to employee benefit plans.

Our contribution is allocated among the participants on the basis of compensation. Each participant’s account is credited with cash or shares of 1st Source common 
stock based on that participant’s compensation earned during the year. After completing five years of service in which they worked at least 1,000 hours per year, 
a participant will be completely vested in their Plan account. Plan participants are entitled to receive distributions from their Plan accounts only upon termination 
of service, which includes retirement or death.

Contribution expense for the years ended December 31, 2006, 2005, and 2004, amounted to $2.39 million, $2.32 million, and $1.66 million, respectively.

Contributions to the defined contribution money purchase pension plan are based on 2% of participants’ eligible compensation. For the years ended December 31, 
2006, 2005, and 2004, total pension expense for this plan amounted to $0.85 million, $0.91 million, and $0.72 million, respectively.

Trustcorp contributes to a defined contribution plan for all of its employees who meet the general eligibility requirements of the plan. Contribution expense for this 
plan for the years ended December 31, 2006, 2005, and 2004, amounted to $0.09 million, $0.14 million, and $0.13 million, respectively.

In  addition  to  the  1st  Source  Corporation  Employee  Stock  Ownership  and  Profit  Sharing  Plan,  we  provide  certain  health  care  and  life  insurance  benefits  for 
substantially all of our retired employees. All of our full-time employees become eligible for these retiree benefits upon reaching age 55 with 20 years of credited 
service. The medical plan pays a stated percentage of eligible medical expenses reduced for any deductibles and payments made by government programs and 
other group coverage. The lifetime maximum benefit payable under the medical plan is $15,000 and for life insurance is $3,000.

Our net periodic postretirement benefit cost recognized in the consolidated financial statements for the years ended December 31, 2006, 2005, and 2004 
amounted to $0.12 million, $0.33 million, and $0.10 million, respectively. Our accrued postretirement benefit cost was not material at December 31, 2006, 
2005, and 2004.

Note O — Contingent Liabilities, Commitments, and Financial Instruments with Off-Balance-Sheet Risk

Contingent Liabilities —1st Source and our subsidiaries are defendants in various legal proceedings arising in the normal course of business. In the opinion of 
management, based upon present information including the advice of legal counsel, the ultimate resolution of these proceedings will not have a material effect on 
our consolidated financial position or results of operation.

Commitments — 1st Source and our subsidiaries are obligated under operating leases for certain office premises and equipment. In 1982, we sold the headquarters 
building and entered into a leaseback agreement with the purchaser. At December 31, 2006, the remaining term of the lease was five years with options to renew 
for up to 15 additional years. Approximately 30% of the facility is subleased to other tenants.

Future minimum rental commitments for all noncancellable operating leases total approximately, $2.68 million in 2007, $2.31 million in 2008, $2.05 million 
in 2009, $1.72 million in 2010, $1.60 million in 2011, and $1.48 million, thereafter. As of December 31, 2006, future minimum rentals to be received under 
noncancellable subleases totaled $3.03 million.

Financial  Instruments  with  Off-Balance-Sheet  Risk  —  To  meet  the  financing  needs  of  our  clients,  1st  Source  and  our  subsidiaries  are  parties  to  financial 
instruments with off-balance-sheet risk in the normal course of business. These off-balance-sheet financial instruments include commitments to originate, purchase 
and sell loans, and standby letters of credit. The instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized 
in the consolidated statements of financial condition.

k

Our exposure to credit loss in the event of nonperformance by the other party to the financial instruments for loan commitments and standby letters of credit 
is represented by the dollar amount of those instruments. We use the same credit policies and collateral requirements in making commitments and conditional 
obligations as we do for on-balance-sheet instruments.

Loan commitments have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to 
expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

Trustcorp and the Bank grant mortgage loan commitments to borrowers, subject to normal loan underwriting standards. The interest rate risk associated with these 
loan commitments is managed by entering into contracts for future deliveries of loans.

Letters of credit are conditional commitments issued to guarantee the performance of a client to a third party. The credit risk involved and collateral obtained in 
issuing letters of credit are essentially the same as those involved in extending loan commitments to clients.

As of December 31, 2006 and 2005, 1st Source and our subsidiaries had commitments outstanding to originate and purchase mortgage loans aggregating 
$113.25 million and $130.73 million, respectively. Outstanding commitments to sell loans aggregated $73.87 million at December 31, 2006, and $98.39 
million at December 31, 2005. Standby letters of credit totaled $83.15 million and $76.43 million at December 31, 2006 and 2005, respectively. Standby 
letters of credit have terms ranging from six months to one year.

Note P — Derivative Financial Instruments

We have certain interest rate derivative positions that are not designated as hedging instruments. These derivative positions relate to transactions in which we enter 
into an interest rate swap with a client while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each 
transaction, we agree to pay interest to the client on a notional amount at a variable interest rate and receive interest from the client on a same notional amount 
at a fixed interest rate. At the same time, we agree to pay another financial institution the same fixed interest rate on the same notional amount and receive the 
same variable interest rate on the same notional amount. The transaction allows our client to effectively convert a variable rate loan to a fixed rate. Because we act 
as an intermediary for our client, changes in the fair value of the underlying derivative contracts offset each other and do not impact our results of operations. At 
December 31, 2006, the notional amount of non-hedging interest rate swaps was $14.55 million.

Note Q — Regulatory Matters

We are subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet minimum capital requirements can result 
in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a material effect on our financial statements. Under 
capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that involve quantitative measures 
of our assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. Our capital amounts and classification are subject 
to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require us to maintain minimum amounts and ratios of total capital and Tier I capital to 
risk-weighted assets and of Tier I capital to average assets. We believe that we meet all capital adequacy requirements to which we are subject.

The most recent notification from the Federal bank regulators categorized the Bank, the largest of our subsidiaries, as “well capitalized” under the regulatory 
framework for prompt corrective action. To be categorized as “well capitalized” we must maintain minimum total risk-based, Tier I risk-based, and Tier I leverage 
ratios as set forth in the table below. There are no conditions or events since that notification that we believe will have changed the institution’s category. 

As discussed in Note L, the capital securities held by the Capital Trusts qualify as Tier 1 capital under Federal Reserve Board guidelines.

The actual and required capital amounts and ratios for 1st Source Corporation and 1st Source Bank, as of December 31, 2006, are presented in the table

The Bank is required to maintain noninterest bearing cash balances with the Federal Reserve Bank. The average balance of these deposits for the years ended 
December 31, 2006 and 2005, were approximately $6.23 million and $8.45 million, respectively.

Dividends that may be paid by a subsidiary bank to the parent company are subject to certain legal and regulatory limitations and also may be affected by capital 
needs, as well as other factors. Without regulatory approval, the Bank can pay dividends in 2007 of up to $67.14 million, plus an additional amount equal to its 
net profits for 2007, as defined by statute, up to the date of any such dividend declaration.

Our mortgage subsidiary, Trustcorp, is required to maintain minimum net worth capital requirements established by various governmental agencies. Trustcorp’s 
net worth requirements are governed by the Department of Housing and Urban Development and GNMA. As of December 31, 2006, Trustcorp met its minimum 
net worth capital requirements.

* Represents estimated cash outflows required to currently settle the obligations at current market rates.

We used the following methods and assumptions in estimating the fair value of our financial instruments:

Cash and Cash Equivalents — The carrying values reported in the consolidated statements of financial condition for cash and due from banks, Federal funds sold 
and interest bearing deposits with other banks approximate fair values for these assets.

Investment Securities — Fair values for securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are 
estimated based on quoted market prices of comparable investments.

Loans and Leases — For variable rate loans and leases that reprice frequently and with no significant change in credit risk, fair values are based on carrying 
values. The fair values for certain real estate loans (e.g., one-to-four single family residential mortgage loans) are based on quoted market prices of similar loans 
sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. The fair values of all other loans and leases are estimated using 
discounted cash flow analyses which use interest rates currently being offered for loans and leases with similar terms to borrowers of similar credit quality.

Mortgages Held for Sale — The fair value of loans held for sale is determined based upon the market sales price of similar loans.

Deposits — The fair values for all deposits other than time deposits are equal to the amounts payable on demand (the carrying value). Fair values of variable 
rate time deposits are equal to their carrying values. Fair values for fixed rate time deposits are estimated using discounted cash flow analyses using interest rates 
currently being offered for deposits with similar remaining maturities.

Short-Term Borrowings — The carrying values of Federal funds purchased, securities sold under repurchase agreements, and other short-term borrowings, 
including our liability related to mortgage loans available for repurchase under GNMA optional repurchase programs, approximate their fair values. 

Long-Term Debt and Mandatorily Redeemable Securities — The fair values of long-term debt are estimated using discounted cash flow analyses, based on our 
current estimated incremental borrowing rates for similar types of borrowing arrangements. The carrying values of mandatorily redeemable securities are based 
on approximate fair values.

Subordinated Notes — Fair values are based on quoted market prices, where available. If quoted market prices are not available, fair values are estimated based 
on calculated market prices of comparable securities.

Interest Rate Swaps — The carrying value of interest rate swaps is equal to the fair value. The fair value is based on the estimated amount we would receive or 
pay to terminate the contract, taking into account the current interest rate.

Off-Balance-Sheet Instruments — Contract and fair values for certain of our off-balance-sheet financial instruments (guarantees and loan commitments) are 
estimated based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’
credit standing.

Limitations — Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instruments. 
Because  no  market  exists  for  a  significant  portion  of  our  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 such factors.

These estimates do not reflect any premium or discount that could result from offering for sale at one time our entire holdings of a particular financial instrument. 
These estimates are subjective in nature and require considerable judgment to interpret market data. Accordingly, the estimates presented herein are not necessarily 
indicative of the amounts we could realize in a current market exchange, nor are they intended to represent the fair value of 1st Source as a whole. The use of 
different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. The fair value estimates presented 
herein are based on pertinent information available to management as of the respective balance sheet date. Although management is not aware of any factors that 
would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued since the presentation dates, and therefore, 
estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein.

Other significant assets, such as mortgage banking operation, premises and equipment, other assets, and liabilities not defined as financial instruments, are not 
included in the above disclosures. In addition, for investment and mortgage-backed securities, the income tax ramifications related to the realization of unrealized 
gains and losses can have a significant effect on fair value estimates and have not been considered in many of the estimates. Also, the fair value estimates for 
deposits  do  not  include  the  benefit  that  results  from  the  low-cost  funding  provided  by  the  deposit  liabilities  compared  to  the  cost  of  borrowing  funds  in  the 
market.

Note S — Subsequent Event

On February 19, 2007, we entered into a definitive agreement of merger with FINA Bancorp, Inc. (FINA), in which 1st Source will acquire FINA in an exchange 
of cash and stock. FINA, headquartered in Valparaiso, Indiana, owns First National Bank, Valparaiso, a full service bank with approximately $620.00 million in 
assets. The merger, approved by the directors of both companies, is valued at approximately $135.00 million, or $3,206.57 per FINA share. The price represents 
approximately 196% of book value and 41.5 times 2006 earnings before securities losses. 1st Source will pay a minimum of 40% and a maximum of 42% of the 
purchase price in shares of 1st Source common stock, and the remainder of the purchase price will be paid in cash. The precise exchange ratio will be established 
at closing based on 1st Source’s stock price prior to the completion of the merger. FINA shareholders will be able to choose whether to receive 1st Source common 
stock or cash pursuant to election procedures described in the definitive agreement, subject to 1st Source’s ability to reallocate elections on a proportionate basis. 
The merger is subject to customary closing conditions, including regulatory approval and is expected to be completed in the second quarter of 2007. We believe 
the purchase of FINA is a natural extension of our service area and is consistent with our growth market expansion initiatives.

ITEM 9A. CONTROLS AND PROCEDURES.

1st Source carried out an evaluation, under the supervision and with the participation of 1st Source’s management, including 1st Source’s Chief Executive Officer 
and Chief Financial Officer, of the effectiveness of the design and operation of 1st Source’s disclosure controls and procedures pursuant to Exchange Act Rule 13a-
15. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, at December 31, 2006, 1st Source’s disclosure controls 
and procedures are effective in accumulating and communicating to management (including such officers) the information relating to 1st Source (including its 
consolidated subsidiaries) required to be included in 1st Source’s periodic SEC filings.

MANAGEMENT REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management  of  1st  Source  Corporation  (“1st  Source”)  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting. 
1st Source’s internal control over financial reporting includes policies and procedures pertaining to 1st Source’s ability to record, process, and report reliable 
information. Actions are taken to correct any deficiencies as they are identified through internal and external audits, regular examinations by bank regulatory 
agencies, 1st Source’s formal risk management process, and other means. 1st Source’s internal control system is designed to provide reasonable assurance to 1st 
Source’s management and Board of Directors regarding the preparation and fair presentation of 1st Source’s published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only 
reasonable assurance with respect to financial statement preparation and presentation. Further, because of changes in conditions, the effectiveness of internal 
control may vary over time.

1st Source’s management assessed the effectiveness of internal control over financial reporting as of December 31, 2006. In making this assessment, it used 
the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework. Based on 
management’s assessment, we believe that, as of December 31, 2006, 1st Source’s internal control over financial reporting is effective based on those criteria.

Ernst & Young LLP, independent registered public accounting firm, has issued an attestation report on management’s assessment of 1st Source’s internal control 
over financial reporting. This report appears on page 25.
