Report of Independent Registered Public Accounting Firm

Plan Participants and the Corporate Benefits Committee of

The FleetBoston Financial Savings Plan

We have audited the accompanying statement of net assets available for benefits of the FleetBoston Financial Savings Plan (the “Plan”) as of December 31, 2004 and the related statement of changes in net assets available for benefits for the year then ended. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

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

In our opinion, the financial statement referred to above presents fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2004 and the related statement of changes in net assets available for benefits for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

Our audit was conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held (at end of year) is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

Notes to Financial Statements (continued)

1. Description of the Plan

The FleetBoston Financial Savings Plan (the Plan) was adopted by FleetBoston Financial Corporation effective January 1, 1989. The Plan has been subsequently amended at various times to affect the combination of certain other benefit plans and various regulatory changes.

Effective April 1, 2004 Bank of America Corporation (the Company or Employer) became the Plan Sponsor as a result of the merger with FleetBoston Financial Corporation. Each share of FleetBoston Financial common stock held in the FBF Common Stock Fund was replaced by .5553 shares of Bank of America Corporation Common Stock and the fund name was changed to Bank of America Common Stock Fund.

The Plan is a defined contribution plan sponsored by the Company. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Fleet National Bank, a subsidiary of the Company, serves as trustee for the Plan.

Certain subsidiaries and affiliates of former FleetBoston Financial Corporation are participating employers in the Plan.

Mergers and Transfers Activity

Effective December 13, 2004, the Progress Financial Corporation 401(k) Plan was merged into the Plan. The Plan was amended to permit the merger and total assets transferred to the Plan during 2004 were $3,484,102. Each Progress participant became a Plan participant on December 13, 2004, if they had not previously enrolled as an eligible employee.

2. Summary of Significant Accounting Policies

Basis of Accounting

The financial statements of the Plan are prepared under auditing standards generally accepted in the United States of America using the accrual method of accounting.

2. Summary of Significant Accounting Policies (continued)

Investment Valuation

Investments are stated at fair value. Securities traded on national securities exchanges are valued at the last reported sales price on the last business day of the year. The Company’s stock is valued at its quoted market price. Investments in mutual funds and common/ collective trusts are valued at the redemption price established by the trustee of the fund generally based on the fair value of the underlying assets. Short-term investments and participant notes receivable are valued at cost, which approximates fair value.

Securities Transactions

Securities purchased and sold are recorded on the respective trade dates. Realized profits and losses are computed based on the average cost of securities sold.

Dividend income is recorded on the ex-dividend date. Interest income is accounted for on the accrual basis.

In the event of withdrawal, participants in the Bank of America Common Stock Fund may receive shares of the common stock of the Company. The realized gain or loss resulting from distributions in kind is based on the difference between the average cost and the value of the stock on the effective date of the distribution.

Administrative Expenses

All expenses associated with the administration of the Plan, with the exception of investment management fees, are paid directly by the Company. Investment management fees are paid by the Plan.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates.

2. Summary of Significant Accounting Policies (continued)

Risks and Uncertainties

The Plan invests in a combination of investment securities which are exposed to various risks, such as interest rate, market and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect participants account balances and the amounts reported in the statements of net assets available for benefits and the statements of changes in net assets available for benefits.

Investment Options

Plan participants are able to direct the investment of their Plan holdings (employer and employee contributions) into various investment options offered under the Plan on a daily basis. The investment options consist of common trusts, common stock, employer common stock, mutual funds, self-directed brokerage (closed to new investments and limited to a group of certain participants with balances merged into the Plan) and loans.

3. Investments

The Plan has a Trust Agreement with Fleet National Bank, a related party (see note 11) as Trustee, providing for the management, investment and reinvestment of Plan assets. The Plan has additional custody agreements with AMVESCAP National Trust Company and State Street Bank and Trust Company.

Each participant chooses the fund or funds in which contributions are to be invested. Contributions can be invested entirely in one fund or split between two or more funds in one percent multiples. Participants may elect to modify existing investment allocations on a periodic basis subject to the provisions of the Plan.

7

Notes to Financial Statements (continued)

3. Investments (continued)

The following investments represent 5% or more of the Plan’s net assets available for benefits at December 31:

During the year ended December 31, 2004, the Plan’s investments (including investments purchased, sold, as well as held during the year) appreciated in fair value as follows:

4. Contributions

Each participant may elect to contribute not less than one percent nor more than thirty-five percent of their compensation to the Plan by regular payroll deductions. For purposes of the Plan, compensation is generally defined as the base salary plus overtime. If base salary is less than $75,000, commissions and non-discretionary incentive pay is included until pay reaches a combined maximum of $75,000. Eligible compensation does not include bonuses, payments for long-term disability, amounts paid for unused vacation, or lump sum salary continuation payments paid as part of a severance agreement. Eligible pay also may include non-lump sum salary continuation pay, but only if provided for under an applicable severance arrangement.

8

FleetBoston Financial Savings Plan

Notes to Financial Statements (continued)

4. Contributions

The employer contributes a matching amount depending on years of vesting service as follows: 50% for each dollar contributed (up to 6% of eligible pay) during the first four calendar quarters beginning the quarter following the date on which a participant completes one year of vesting service; 75% for each dollar contributed (up to 6% of eligible pay) during the next four calendar quarters, and 100% for each dollar contributed (up to 6% of eligible pay) during any calendar quarter thereafter. Participants receive employer contributions on a payroll by payroll basis.

A full-time employee is immediately eligible to become a participant without any service requirement. Part-time employees are eligible to participate the quarter following one year of eligibility service. An employee is credited with a year of service when he or she completes a minimum of 1,000 hours of service during the first 12 months of employment or in any calendar year beginning after the hire date. Special rules apply for participants transferring in from other plans.

5. Vesting

Participants are immediately vested in their contributions plus actual earnings thereon.

The following table sets forth the basic vesting schedule for employer matching contributions to the Plan, which is subject to the special rules for participants transferred in from other plans:

9

FleetBoston Financial Savings Plan

Notes to Financial Statements (continued)

5. Vesting (continued)

A participant becomes fully vested if they reach their normal retirement date (age 65), upon incurring a disability or in the event of death.

Forfeitures of account balances which are not vested are used to decrease future matching contributions by the employer. For the year ended December 31, 2004, employer contributions were offset by non-vested forfeited amounts totaling approximately $1,957,200. At December 31, 2004, forfeited non-vested accounts totaled $145,805.

If a participant terminates employment and receives the vested portion of the employer account immediately following such termination, the non-vested portion is forfeited as of the effective date of the participant’s lump sum distribution.

A forfeiture of the non-vested portion of a participant’s employer account will also occur after six consecutive one-years of absence. If a participant is rehired prior to such six consecutive one-years of absence, the forfeited portion of their employer account will be restored; provided, however, that if such participant received a distribution of their vested account, they must repay to the Plan all amounts in their company matching account previously distributed to them from the Plan.

6. Participant Accounts

Each participant’s account is credited with the participant’s contribution and allocations of the Company’s contribution and Plan earnings and debited with administrative expenses. Plan earnings are computed daily for each fund. The earnings are credited to participants’ accounts daily based upon the proportion of each participant’s weighted average account balance to the total value of the fund. Loan interest is credited to the investment funds of the participant making the payment. Participants are entitled to the benefit that can be provided from the participants vested account.

7. Loans to Participants

Participants may borrow up to one-half of their total vested account. The minimum amount of any loan is $1,000. The maximum amount of any loan may not exceed $50,000 reduced by the highest outstanding loan balance of any loan outstanding in the previous twelve months. Loans are made for a period of 3 to 54 months and bear interest at the prime rate of interest plus one percent. Interest rates ranged from 4.00% to 11.50% at December 31, 2004 and 2003.

10

FleetBoston Financial Savings Plan

Notes to Financial Statements (continued)

7. Loans to Participants (continued)

Each loan is treated as a separate investment of the borrowing participant’s account. The cash for the loan is withdrawn from the participant’s investment funds and the principal amount is recorded as a receivable in the loan fund. The principal and interest payments made are credited to the participant’s investment funds. The loan fund is reduced by the principal portion of each payment.

When a participant is terminated, the entire balance of each loan becomes due and payable by the end of the quarter following the quarter in which the participant terminates and is deducted from the participant’s vested account balance if not repaid within this period.

8. Distributions

A participant who retires or becomes totally disabled has the following choices as to the distribution of his or her account:

In the event of termination of employment other than retirement, the participant’s account will be distributed at the participant’s discretion as either a lump sum distribution in cash or a lump sum distribution in cash of the amount in all funds plus shares of the Company’s common stock representing their account in the Bank of America Common Stock Fund. The lump sum payments may be deferred until a later date, but not beyond age 70 ¹/2.

11

FleetBoston Financial Savings Plan

Notes to Financial Statements (continued)

8. Distributions (continued)

Beneficiaries of participants may elect lump-sum distribution (including whole shares of FBF common stock representing the value of all or a portion of the interest in the Bank of America Common Stock Fund) or installments.

A participant may apply for a withdrawal up to their total account balance, excluding pre-1988 earnings, in the event of financial hardship. All such withdrawals are subject to the approval of the Plan Administrator. Financial hardship is determined by the Plan Administrator in accordance with safe harbor regulations and with uniform non-discriminatory standards. In addition, a participant may elect to make discretionary withdrawals from the vested portion of their account subject to certain limitations. Discretionary withdrawals can be made once every six months.

9. Income Tax Status

The Plan has received a determination letter from the Internal Revenue Service dated August 8, 2003, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (IRC) and, therefore, the related trust is exempt from taxation. The Plan has been amended since receiving a determination letter but the Corporate Benefits Committee believes that the Plan continues to qualify as a tax-exempt defined contribution plan, and the Retirement Committee is not aware of any course of action or series of events that has occurred that might adversely affect the Plan’s qualified status.

10. Right to Terminate

Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100 percent vested in their accounts.

12

FleetBoston Financial Savings Plan

Notes to Financial Statements (continued)

11. Related Party Transactions

The Plan invests in a unitized stock fund, the Bank of America Common Stock Fund (the “Fund”) which is comprised of a short-term investment component and common shares of Bank of America Corporation, the Plan sponsor. The unit values of the Fund are recorded and maintained by the Trustee.

During the year ended December 31, 2004, the Plan purchased units of the Fund in the approximate amount of $181,736,195, sold units of the Fund in the approximate amount of $246,595,133, and had net appreciation plus dividends and interest on the Fund in the approximate amount of $203,455,038. The total value of the Plan’s interest in the Fund was approximately $1,017,356,255 and $914,301,118 at December 31, 2004 and 2003, respectively.

Certain of the Plan’s assets are invested in mutual funds, common trust, company stock and collective trusts for which the Company provides investment advisory services. Expenses paid to the Company and/or its affiliates by the Plan during the year ended December 31, 2004 were approximately $1,180,946. These transactions, as well as participant loans, qualify as party-in-interest transactions.

Advanta, a business acquired by former FleetBoston Financial Corporation, maintains a small minority interest in a portion of the credit card business of the Company and as such transactions in their common stock qualify as party in interest. No fees are paid by the Plan to Advanta.

12. Differences Between Financial Statements and Form 5500

The following is a reconciliation of net assets available for benefits per the financial statements to the Form 5500:

Amounts allocated to withdrawn participants are recorded on the Form 5500 for benefit claims that have been processed and approved for payment prior to year-end but not yet paid.

13. Subsequent Events

The Corporation amended and restated the Plan effective January 1, 2005 to make the following changes, among others:

In addition, the Plan’s Trust Agreement was restated effective January 1, 2005. With regard to the voting and tender of Bank of America Corporation common stock held in the Plan, a participant’s shares of stock will not be voted or tendered if a participant does not provide voting or tender directions.

Effective June 13, 2005, Bank of America, N.A. became the Trustee as a result of the merger with Fleet National Bank.
