PART I



|ITEM  1. |  | BUSINESS
|-------- |  | --------



General



AmSouth Bancorporation (AmSouth) is a financial holding company and bank holding company, which was organized in 1970 as a Delaware corporation and began doing business in 1972. AmSouth offers a broad range of bank and bank-related services
through its principal subsidiary AmSouth Bank (the Bank) and its other subsidiaries. At December 31, 2003, AmSouth had total consolidated assets of approximately $46 billion.



The Bank is an Alabama banking corporation and a wholly owned subsidiary of AmSouth. As of December 31, 2003, the Bank
had total consolidated assets of approximately $45.6 billion and total consolidated deposits of approximately $30.8 billion. As of December 31, 2003, the assets of the Bank constituted virtually all of the assets of AmSouth.



AmSouth has three reportable segments: Consumer Banking, Commercial Banking
and Wealth Management. Consumer Banking delivers a full range of financial services to individuals and small businesses, including loan products such as residential mortgages, equity lending, credit cards, and loans for automobile and other personal
financing needs, and various products designed to meet the credit needs of small businesses. Consumer Banking also offers various deposit products to meet customers savings and transaction needs. Commercial Banking meets the requirements of
large and middle market corporate customers with a comprehensive array of credit, treasury management, international and capital markets services. Included among these are several specialty services such as real estate finance, asset based lending
and commercial leasing. Wealth Management is comprised of trust, institutional, retirement and broker-dealer services. This area includes traditional trust, custody and agency services as well as a substantial selection of investment management
services.



These services are offered to businesses and
individuals through the Banks approximately 650 offices located in Alabama, Florida, Tennessee, Mississippi, Louisiana and Georgia. In addition to these offices, the Bank operates a network of more than 1,200 automated teller machines that are
linked with shared automated tellers in all 50 states. Further segment information is included in Managements Discussion and Analysis of Financial Condition and Results of Operations and Note 20 of the Notes to Consolidated Financial
Statements, both of which are incorporated herein by reference pursuant to Items 7 and 8 of this Form 10-K.



As of December 31, 2003, AmSouth and its subsidiaries had approximately 12,385 full-time equivalent employees.



Competition



AmSouths subsidiaries compete aggressively with banks located in
Alabama, Florida, Tennessee, Mississippi, Louisiana and Georgia, as well as large banks in major financial centers, and with other financial institutions, such as savings and loan associations, credit unions, consumer finance companies, brokerage
firms, insurance companies, investment companies, mortgage companies, and financial service operations of major retailers, including automotive retailers. Competition is based on a number of factors, including prices, interest rates, services, and
availability of products. At December 31, 2003, AmSouth was the 21st largest bank holding company headquartered in the United States based on total assets.



Competition between financial institutions is also affected by the Gramm-Leach-Bliley Act, which became law in late 1999. This Act significantly revised
the laws regulating banks and bank holding companies and other providers of financial services, enabling bank holding companies and foreign banks that meet applicable

##### Table of Contents

statutory requirements to engage in a broader range of services and to compete more efficiently in existing business lines. The Gramm-Leach-Bliley Act
authorizes financial holding companies that are deemed well capitalized and well managed by the Board of Governors of the Federal Reserve System (the Federal Reserve Board) to engage in securities, insurance and other activities that are financial
in nature or incidental or complementary to a financial activity and that do not pose a substantial risk to the safety and soundness of depository institutions or the financial system generally. Subsidiaries of financial holding companies that are
insured depository institutions must have a rating of at least satisfactory under the Community Reinvestment Act of 1977 for such financial holding companies to engage in these expanded financial activities. In 2000, AmSouth elected to
be a financial holding company under the Gramm-Leach-Bliley Act.



Business Combinations



AmSouth continually
evaluates business combination opportunities and sometimes conducts due diligence activities in connection with them. As a result, business combination discussions and, in some cases, negotiations take place, and transactions involving cash, debt or
equity securities can be expected. Any future business combination or series of business combinations that AmSouth might undertake may be material, in terms of assets acquired or liabilities assumed, to AmSouths financial condition. Business
combinations in the banking industry have historically involved the payment of a premium over book and market values. This practice may result in dilution of book value and net income per share for the acquirers.



Supervision and Regulation



The following discussion addresses the regulatory framework applicable to
financial holding companies, bank holding companies and their subsidiaries, and provides certain specific information relevant to AmSouth. Regulation of financial institutions such as AmSouth and its subsidiaries is intended primarily for the
protection of depositors, the deposit insurance funds of the Federal Deposit Insurance Corporation (the FDIC) and the banking system as a whole, and generally is not intended for the protection of stockholders or other investors.



The following is a summary of certain statutes and regulations that apply to
the operation of banking institutions. Changes in the applicable laws, and in their application by regulatory agencies, cannot necessarily be predicted, but may have a material effect on the business and results of banking organizations, including
AmSouth.



General



As a financial holding company and bank holding company, AmSouth is subject
to regulation and supervision by the Federal Reserve Board under the Bank Holding Company Act of 1956, as amended (the BHCA). A financial holding company may own insured depository institutions and engage through its non-bank affiliates in a broader
range of financial activities than previously permissible for a bank holding company. These activities include underwriting securities, insurance underwriting, merchant banking and insurance company investments, in addition to any activity that the
Federal Reserve Board determines by rule or order to be financial in nature or incidental to such financial activity. The Federal Reserve is responsible for umbrella supervision and examination of financial holding companies. Other
federal and state regulators regulate, supervise and examine the functionally regulated subsidiaries such as insurance companies and broker-dealers.



The Bank is a state bank, chartered under the laws of Alabama, and is a member of the Federal Reserve System. It is generally subject to regulation and
supervision by both the Federal Reserve Board and the Office of the Superintendent of Banking of the State of Alabama (the Superintendent). The Bank is also an insured depository institution and, therefore, subject to regulation by the FDIC. In
addition, the Bank is subject to various requirements and restrictions under federal and state law, including requirements to maintain reserves against deposits, restrictions on the types and amounts of loans that may be granted and the interest
that may be charged

thereon, and limitations on the types of investments that may be made and the types of services that may be offered. Various consumer laws and regulations
also affect the operations of the Bank. In addition to the impact of regulation, commercial banks are affected significantly by the actions of the Federal Reserve Board as it attempts to control the money supply and credit availability in order to
influence the economy.



The Banks subsidiaries are also
subject to regulation, supervision and examination by other federal and state and self-regulatory agencies. For example, AmSouth Investment Services, Inc., a registered broker-dealer, is subject to the supervision of the Securities and Exchange
Commission (SEC), the National Association of Securities Dealers, and state securities and insurance agencies. AmSouth Asset Management, Inc. and AmSouth Investment Management Company LLC, both investment advisers, are subject to regulation by the
SEC in addition to state securities agencies.



Payment of Dividends



AmSouth is a legal entity separate and distinct from its
banking and other subsidiaries. The principal source of cash flow for AmSouth, including cash flow used to pay dividends on AmSouths capital stock and interest and principal on any debt of AmSouth, is dividends from the Bank. There are
statutory and regulatory limitations on the payment of dividends by the Bank to AmSouth as well as by AmSouth to its shareholders. The payment of dividends by AmSouth and the Bank also may be affected by other factors, such as the requirement to
maintain capital at or above regulatory guidelines. See Capital Adequacy and Related Matters below.



Under Alabama law, a bank may not pay a dividend in excess of 90 percent of its net earnings until the banks surplus is equal to at least 20 percent
of capital. The Bank is also required by Alabama law to obtain approval of the Superintendent prior to the payment of dividends if the total of all dividends declared by the Bank in any calendar year will exceed the total of (a) the Banks net
earnings (as defined by statute) for that year, plus (b) its retained net earnings for the preceding two years, less any required transfers to surplus. Also, no dividends may be paid from the Banks surplus without the prior written approval of
the Superintendent.



In addition, as a member of the Federal
Reserve System, the Bank is required by federal law to obtain regulatory approval for the payment of dividends if the total of all dividends declared by the Board of Directors of the Bank in any year could exceed the total of (a) the Banks net
income (as reportable in its Reports of Condition and Income) for that year, plus (b) the Banks retained net income (as defined and interpreted by regulation) for the preceding two years, less any net losses incurred in the current or prior
two years and any required transfers to surplus or a fund for the retirement of preferred stock.



Furthermore, if, in the opinion of the applicable federal bank regulatory authority, a bank is engaged in or is about to engage in an unsafe or unsound
practice (which, depending on the financial condition of the bank, could include the payment of dividends), such authority may require, after notice and a hearing, that such bank cease and desist from such practice. The Federal Reserve Board has
indicated that paying dividends that deplete a banks capital base to an inadequate level would be an unsafe and unsound banking practice. In addition, the Federal Deposit Insurance Act (the FDI Act) imposes restrictions on the payments of
dividends by the Bank, as described under Capital Adequacy and Related MattersPrompt Corrective Action below. Moreover, the Federal Reserve Board has issued a policy statement that provides that bank holding companies and state
member banks should generally pay dividends only out of current operating earnings.



Under dividend restrictions imposed under federal and Alabama law, including those described above, the Bank, without obtaining government approvals, could declare aggregate dividends in 2004 of an amount equal to
$21.3 million plus its net income for 2004.

Capital Adequacy and Related Matters



Capital Guidelines



AmSouth is subject to risk-based capital guidelines adopted by the Federal Reserve Board. The minimum guideline for the ratio of total regulatory capital
(Total Capital) to risk-weighted assets (including certain off-balance-sheet items, such as standby letters of credit) is 8 percent. At least half of the Total Capital must be composed principally of common equity less goodwill and certain other
intangible assets (Tier 1 Capital). The remainder may consist of subordinated debt and a limited amount of loan loss reserves. At December 31, 2003, AmSouths consolidated Tier 1 Capital and Total Capital ratios were 7.71 percent and 11.22
percent, respectively.



In addition, the Federal Reserve Board
has established minimum leverage ratio guidelines for bank holding companies. The guidelines provide for a minimum ratio of Tier 1 Capital to average assets, less goodwill and certain other intangible assets (the Leverage Ratio), of 3 percent for
bank holding companies that meet certain specific criteria, including having the highest regulatory rating. All other bank holding companies generally are required to maintain a Leverage Ratio of at least 4 percent. AmSouths Leverage Ratio at
December 31, 2003 was 6.66 percent. The guidelines also provide that bank holding companies experiencing internal growth or making acquisitions will be expected to maintain strong capital positions substantially above the minimum supervisory levels
without significant reliance on intangible assets. Furthermore, the Federal Reserve Board has indicated that it will consider a Tangible Tier 1 Capital Leverage Ratio (deducting all intangibles) and other indicators of capital strength
in evaluating proposals for expansion or new activities.



The
Bank is also subject to risk-based and leverage capital requirements, similar to those described above. The Bank complied with applicable minimum capital requirements as of December 31, 2003. Neither AmSouth nor the Bank has been advised by any
federal banking agency of any specific minimum Leverage Ratio requirement applicable to it.



Bank regulators have the authority generally to raise capital requirements applicable to banking organizations beyond their current levels. However, the management of AmSouth is unable to predict whether and when
higher capital requirements would be imposed, and, if so, at what levels and on what schedule.



Prompt Corrective Action



The FDI Act requires the federal banking regulators to take prompt corrective action in respect of FDIC-insured depository institutions that do not meet minimum capital requirements. The FDI Act establishes five capital tiers: well
capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. Under applicable regulations, a state member bank is defined as well
capitalized if it maintains a Leverage Ratio of at least 5 percent, a risk-adjusted Tier 1 Capital Ratio of at least 6 percent, a Total Capital Ratio of at least 10 percent and is not subject to any order or written directive to maintain any
specific capital level. A state member bank is defined as adequately capitalized if it maintains a Leverage Ratio of at least 4 percent, a risk-adjusted Tier 1 Capital Ratio of at least 4 percent, and a Total Capital Ratio of at least 8 percent. A
bank may be deemed to be in a capitalization category that is lower than is indicated by its actual capital position if it is operating in an unsafe or unsound manner or receives an unsatisfactory examination rating. AmSouth believes that at
December 31, 2003, the Bank had capital ratios sufficient to qualify as well capitalized. The FDI Act authorizes, and in some cases automatically imposes, serious restrictions on a banks business as it declines in capital-based
tier.



The capital-based prompt corrective action provisions of
the FDI Act and the implementing regulations apply to FDIC-insured depository institutions such as the Bank and are not directly applicable to holding companies, like AmSouth, that control such institutions. However, the Federal Reserve Board has
indicated that it will take appropriate action at the holding company level based on an assessment of the effectiveness of supervisory actions imposed upon subsidiary depository institutions pursuant to such provisions and regulations.

##### Table of Contents

Although the capital categories defined under the prompt corrective action regulations are not directly applicable to AmSouth under existing laws and
regulations, if AmSouth were placed in a capital category it would qualify as well-capitalized as of December 31, 2003.



Brokered Deposits and Pass-Through Insurance



The FDIC has adopted regulations under the FDI Act governing the receipt of brokered deposits. Under the regulations, an FDIC-insured depository
institution cannot accept, roll over or renew brokered deposits unless (a) it is well capitalized or (b) it is adequately capitalized and receives a waiver from the FDIC. A depository institution that cannot receive brokered deposits also cannot
offer pass-through insurance on certain employee benefit accounts. Whether or not it has obtained such a waiver, an adequately capitalized depository institution may not pay an interest rate on any deposits in excess of 75 basis points
over certain prevailing market rates specified by regulation. There are no such restrictions on a depository institution that is well capitalized. Because the Bank was well capitalized as of December 31, 2003, AmSouth believes the brokered deposits
regulation will have no material effect on the funding or liquidity of the Bank.



Holding Company Structure



There are various
legal restrictions on the extent to which AmSouth and its nonbank subsidiaries may borrow or otherwise obtain funding from the Bank. The Bank (and its subsidiaries) may only engage in borrowing and other covered transactions with nonbank
and nonsavings bank affiliates to the following extent: (a) in the case of any single such affiliate, the aggregate amount of covered transactions of the Bank and its subsidiaries may not exceed 10 percent of the capital stock and surplus of the
Bank; and (b) in the case of all affiliates, the aggregate amount of covered transactions of the Bank and its subsidiaries may not exceed 20 percent of the capital stock and surplus of the Bank. Covered transactions also are subject to certain
collateralization requirements. Covered transactions are defined by statute to include a loan or extension of credit, as well as a purchase of securities issued by an affiliate, a purchase of assets (unless otherwise exempted by the
Federal Reserve Board) from the affiliate, the acceptance of securities issued by the affiliate as collateral for a loan, and the issuance of a guarantee, acceptance, or letter of credit on behalf of an affiliate. Regulation W, which comprehensively
implemented statutory restrictions on transactions between a bank and its affiliates, became effective on April 1, 2003. This Regulation combines the Federal Reserve Boards interpretations and exemptions relating to Sections 23A and 23B of the
Federal Reserve Act with interpretations of these statutory sections that were affected by the Gramm-Leach-Bliley Act. For example, Regulation W addresses the definition of financial subsidiaries for the purposes of affiliate
transactions and the valuation of a banks investment in a financial subsidiary affiliate. The adoption and subsequent effectiveness of Regulation W did not have a material impact on AmSouths operations.



Under Federal Reserve Board policy, AmSouth is expected to act as a source of
financial strength for, and to commit resources to support, the Bank. This support may be required at times when, absent such Federal Reserve Board policy, AmSouth may not be inclined to provide it. In addition, any capital loans by a bank holding
company to a subsidiary bank are subordinate in right of payment to deposits and to certain other indebtedness of such subsidiary bank. In the event of a bank holding companys bankruptcy, any commitment by the bank holding company to a federal
bank regulatory agency to maintain the capital of a subsidiary bank will be assumed by the bankruptcy trustee and entitled to a priority of payment.



The FDI Act provides that, in the event of the liquidation or other resolution of an insured depository institution, the claims of depositors
of such institution (including claims by the FDIC as subrogee of insured depositors) and certain claims for administrative expenses of the FDIC as receiver would be afforded a priority over other general unsecured claims against the institution,
including any claims of the banks holding company as a creditor. If an insured depository institution fails, insured and uninsured depositors, along with the FDIC, will be placed ahead of unsecured, nondeposit creditors, including a parent
holding company such as AmSouth, in its capacity as creditor, in order of priority of payment.

Liability for Affiliate Insured Depository Institutions



Under the FDI Act, an insured depository institution, such as the Bank, can
be held liable for any loss incurred by, or reasonably expected to be incurred by, the FDIC in connection with (a) the default of a commonly controlled FDIC-insured depository institution or (b) any assistance provided by the FDIC to any commonly
controlled FDIC-insured depository institution in danger of default. Default is defined generally as the appointment of a conservator or receiver, and in danger of default is defined generally as the existence of
certain conditions indicating that a default is likely to occur in the absence of regulatory assistance. The Bank is currently the only depository institution subsidiary of AmSouth. It is possible, however, that AmSouth will have other depository
institution subsidiaries in the future.



The USA Patriot Act



In 2001, the Uniting and Strengthening America by Providing Appropriate
Tools Required to Intercept and Obstruct Terrorism Act of 2001 (USA Patriot Act) was signed into law. The USA Patriot Act broadened the application of anti-money laundering regulations to apply to additional types of financial institutions, such as
broker-dealers, and strengthened the ability of the U.S. government to detect and prosecute international money laundering and the financing of terrorism. The principal provisions of Title III of the USA Patriot Act require that regulated financial
institutions, including state member banks: (i) establish an anti-money laundering program that includes training and audit components; (ii) comply with regulations regarding the verification of the identity of any person seeking to open an account;
(iii) take additional required precautions with non-U.S. owned accounts; and (iv) perform certain verification and certification of money laundering risk for their foreign correspondent banking relationships. The USA Patriot Act also expanded the
conditions under which funds in a U.S. interbank account may be subject to forfeiture and increased the penalties for violation of anti-money laundering regulations. Failure of a financial institution to comply with the USA Patriot Acts
requirements could have serious legal and reputational consequences for the institution. AmSouth has adopted policies, procedures and controls to address compliance with the requirements of the USA Patriot Act under the existing regulations and will
continue to revise and update its policies, procedures and controls to reflect changes required by the USA Patriot Act and implementing regulations.

|ITEM  3. |  | LEGAL PROCEEDINGS
|-------- |  | -----------------



In the ordinary course of business, AmSouth and its subsidiaries are from time to time named as defendants in or parties to pending and threatened legal
actions and proceedings. Among the actions which are pending against AmSouth are actions brought on behalf of various classes of claimants. These actions and claims, including class actions, are similar to others that have been brought in recent
years against financial institutions and relate to AmSouths lending, collections, loan servicing, depository, investment, trust and other activities. These actions and claims allege violations of consumer protection, securities, banking and
other laws, both state and federal. Some of these claims and actions seek substantial compensatory and punitive damage awards and injunctive relief. Additionally, AmSouth, and certain of its subsidiaries which are regulated by one or more federal
and state regulatory authorities, are the subject of regularly scheduled and special examinations, reviews and investigations conducted by such regulatory authorities and by law enforcement agencies. AmSouth may occasionally have disagreements with
regulatory authorities and law enforcement agencies resulting from these investigations, examinations and reviews.



AmSouth has received a target letter from the U.S. Attorneys Office for the Southern District of Mississippi (USAO) stating that a grand jury is
investigating certain possible criminal violations by AmSouth. The investigation arises from a fraudulent note scheme committed by Louis Hamric and Victor Nance. At the time Hamric and Nance committed the fraud, Hamric was a practicing attorney and
Nance was a registered representative for MONY Securities Corporation. Beginning in 2000, Hamric and Nance opened custody accounts at AmSouth Bank to hold fraudulent notes owed by Hamric. In 2002 Hamric defaulted on promissory notes owed to
approximately 50 of the investors totaling approximately $15 million. AmSouth and other institutions have paid settlements to most of the investors in aggregate amounts exceeding 100% of the principal they invested plus interest. AmSouth has settled
all but one of the civil suits filed against it. Hamric, Nance, and other individuals connected with them pled guilty to the scheme in 2003. AmSouth believes that the USAOs investigation includes the failure to discover the fraud and timely
file a suspicious activity report, potential privacy violations regarding disclosure of customer information, and possible obstruction regarding the grand jury investigation and the initial review of the matter by the Federal Reserve. The grand jury
for the Southern District of Mississippi recently indicted a former employee of the Bank, who left the Bank in 2001, for alleged misrepresentations to the grand jury. The former employee has pled not guilty. AmSouth is cooperating fully with the
investigation.



It may take a number of years to fully and
finally resolve the legal proceedings, including actions, claims and disagreements with regulators and law enforcement agencies, currently pending due to their complexity and for other reasons. Further, in view of the inherent difficulty of
predicting the outcome of such proceedings, AmSouth cannot state what the eventual outcome of these proceedings will be. Nonetheless, based on current knowledge and the advice of legal counsel, and although the potential impact of the filing of
criminal charges is inherently unpredictable, AmSouths management is of the opinion that the ultimate resolution of these legal proceedings, including the matters described above, will not have a material adverse effect on the consolidated
financial condition, operations or liquidity of AmSouth.

Note 1. In 2002, AmSouth adopted
Statement of Financial Accounting Standards No. 142 Goodwill and Other Intangible Assets which requires companies to no longer amortize goodwill but to test goodwill periodically for impairment. Accordingly, 2003 and 2002 results no
longer include goodwill amortization expense. For additional discussion, see Note 2 in the Notes to Consolidated Financial Statements, which are incorporated herein by reference pursuant to Item 8 of this Form 10-K.

|ITEM 9A. |  | CONTROLS AND PROCEDURES
|-------- |  | -----------------------



As a bank holding company, AmSouth is subject to the internal control reporting requirements of the Federal Deposit Insurance Corporation Improvement Act,
which became effective in 1993 (FDICIA). FDICIA requirements include an annual assessment by our Chief Executive Officer (CEO) and Chief Financial Officer (CFO) of the effectiveness of our internal controls over financial reporting, which generally
include those controls relating to the preparation of our financial statements in conformity with accounting principles generally accepted in the United States. In addition, under FDICIA our independent auditors have annually examined and attested
to, without qualification, managements assertions regarding the effectiveness of our internal controls. Accordingly, we have had an established process of maintaining and evaluating our internal controls over financial reporting.



In connection with recent legislation and regulations, we have implemented
enhancements to certain of our processes, which include establishing an SEC Filings Review Committee and generally formalizing and documenting disclosure controls and procedures that we already had in place. Any future refinements to our controls
and procedures will continue to build upon our existing framework.



An evaluation was performed as of December 31, 2003 under the supervision and with the participation of AmSouths management, including the CEO and CFO, of the effectiveness of the design and operation of AmSouths disclosure
controls and procedures. Based on that evaluation, AmSouths management, including the CEO and CFO, concluded that AmSouths disclosure controls and procedures were effective as of December 31, 2003. There have been no significant changes
in AmSouths internal controls or in other factors that could significantly affect internal controls subsequent to December 31, 2003.
