NOTES TO FINANCIAL STATEMENTS

Note 1  Basis of presentation and informational disclosures



Basis of presentation



The unaudited consolidated financial statements of Mellon are prepared in accordance with generally accepted accounting principles for
interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. These financial statements should be read in conjunction with Mellons 2004 Annual Report on Form 10-K. In the opinion of management, all
normal recurring adjustments necessary for a fair presentation of the financial position and results of operations for the periods have been included. In addition to reclassifications related to discontinued operations, other reclassifications have
been made to prior periods to place them on a basis comparable with current period presentation.



For details of guarantees, see Other guarantees and indemnities in the table on page 37, and the paragraphs under the subheading Other guarantees and indemnities pages 38 and 39. The
information in the table and those paragraphs are incorporated by reference into these Notes to Financial Statements.



Pro forma cost of stock options



Effective Jan. 1, 2003, we adopted the fair value recognition provisions of Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-Based
Compensation, prospectively for all employee awards granted, modified, or settled after Jan. 1, 2003. During the first quarter of 2005, options totaling 573,020 shares were granted with a weighted-average fair value of $5.82 per share. Stock
option expense was determined by using the Black-Scholes option pricing model and totaled $4 million after-tax in the first quarter of 2005, $3 million after-tax in the first quarter of 2004 and $3 million after-tax in the fourth quarter of 2004.



As required to be disclosed by SFAS No. 148, Accounting for Stock-Based
CompensationTransition and Disclosure, an amendment of SFAS No. 123, the following table illustrates the pro forma effect on income and earnings per share if the fair value based method had been applied to all awards in each period.
Awards under our plans generally vest over periods of three or more years. Therefore, the cost related to stock-based employee compensation included in the determination of net income for 2005 is less than that which would have been recognized if
the fair value based method had been applied to all awards granted in prior periods.

The Black-Scholes option pricing model requires the use of subjective assumptions which can materially affect fair value estimates. Therefore, this model does not necessarily provide a reliable single measure of the fair value of
Mellons stock options. The fair value of each stock option was estimated on the date of the grant using the following weighted-average assumptions:

Mellon expects to make cash contributions to its funded defined benefit pension plans, principally outside the U.S., of approximately $12 million in the remainder of 2005. Cash contributions in the first quarter of 2005 totaled $14 million.



Note 2Contingent and deferred
consideration related to acquisitions



Mellon completed the acquisition of DPM
during the first quarter of 2005 for a total cost of $52 million, paid in cash. Goodwill and intangibles related to this acquisition totaled $47 million. This acquisition added $30 billion to assets under administration and custody. Additional cash
consideration for prior acquisitions of $20 million was paid in the first quarter in 2005.



We record contingent purchase payments when amounts are determinable and become issuable. Amounts generally become determinable and issuable when an acquisition reaches a certain level of performance. At March 31,
2005, we are potentially obligated to pay contingent additional consideration of a maximum possible amount of approximately $325 million for all acquisitions, over the next five years, assuming that all performance criteria are met. None of the
potential contingent additional consideration was recorded as goodwill at March 31, 2005. In addition, we are obligated to pay deferred consideration in equal annual installments of $12.5 million for a total of $50 million, for the Standish Mellon
acquisition, which has a remaining obligation of $25 million. The $47 million net present value of this obligation was recorded as additional goodwill in the fourth quarter of 2002.



Mellon owns 70% of Mellon Financial Services Asset Management S.A., a Brazilian institutional asset management and asset servicing company.
The minority interest owners have attempted to exercise certain put rights, which obligate our subsidiary to purchase the remaining 30% of the company. The purchase price, as defined, is based on the levels of assets under management and
administration, among other things. The minority interest owners and Mellon disagree on the computation of the purchase price. This dispute is in binding arbitration. We offered $4 million for the remaining 30% of the company and the minority
interest owners made an initial request of $42 million, based upon exchange rates in effect at the time.

Note 3Discontinued operations



In the
first quarter of 2005, Mellon incurred a net loss of $50 million from discontinued operations, comprised of the following results:



| |  |  | In the first quarter of 2005, we adopted discontinued operations accounting for the HR consulting practices, benefits administration and business process outsourcing businesses
included in the former Human Resources & Investor Solutions sector. After a thorough review, it was determined that the investments required to compete successfully in those businesses could be better utilized by building on the strong positions
of our other core businesses. On March 16, 2005, we announced the signing of a definitive agreement to sell these businesses to Affiliated Computer Services, Inc. (ACS). The sale is expected to close by the end of the second quarter of 2005. This
transaction would result in a pre-tax gain, before other expenses and asset writedowns. However, due to tax expense resulting from a lower tax basis related to the nondeductible goodwill included in this transaction, goodwill impairment and other
expenses of approximately $40 million after-tax were recorded in the first quarter of 2005. Additional costs or asset writedowns are expected to be recorded in the second quarter of 2005 and thereafter. The total after-tax loss, including other
expenses and asset writedowns, resulting from this transaction is currently expected to be in a range of approximately $75 to $85 million.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In the fourth quarter of 2004, we adopted discontinued operations accounting for certain businesses in Australia. We sold our business providing comprehensive multi-manager defined
contribution services to the intermediary market in the fourth quarter of 2004, as it was deemed that this business had insufficient scale to compete in the marketplace. In addition, in March 2005, we reached an agreement to sell our Australian
consulting and administration businesses to Mercer Human Resource Consulting. This transaction closed in the second quarter of 2005. An after-tax loss of $2 million for goodwill and intangible impairment and other expenses was recorded in the first
quarter of 2005. These businesses were formerly included primarily in the Institutional Asset Management sector.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Also reflected in discontinued operations in the first quarter of 2005 is an after-tax loss of $9 million resulting from the ongoing operation of the HR businesses that will be sold
to ACS and the Australian consulting and administration businesses, as well as a $1 million gain on disposal from residual activity from the lines of business servicing retail consumer and small business/middle market customers that were exited in
2001 and 2002. Excluding the goodwill and intangible impairment and other expenses discussed above, in the first quarter of 2005: the HR businesses generated $154 million of revenue and $165 million of operating expenses, for a pre-tax loss of $11
million; the Australian businesses generated $5 million of revenue and $7 million of operating expenses, for a pre-tax loss of $2 million; and the residual activity accounted for a gain on disposals of $1 million resulting from the favorable
resolution of estimates made at the time of disposition.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



In
accordance with GAAP, the results of the businesses discussed above are reflected as discontinued operations in all income statements presented. Because the lines of business included in discontinued operations are discrete lines of business
providing services no longer provided by Mellons continuing lines of business, the disposition of these businesses has no material impact on continuing operations going forward.



All information in these Financial Statements and Notes reflects continuing operations unless otherwise noted.

The
unrealized losses on securities of $145 million was virtually all related to interest rates. Nearly all of the securities with unrealized losses are AAA rated or carry government agency guarantees. Approximately 88% of these 1,009 investments have
been in a continuous unrealized loss position for less than 12 months. Management believes the collection of the contractual principal and interest is probable and therefore all unrealized losses are considered to be temporary.

Summary of financial results

Overview



Mellon Financial Corporation is a global financial services company that strives to meet or
exceed the expectations of our clients, which are corporations, institutions and high net worth individuals primarily in the United States and Europe. In this report, Mellon Financial Corporation and its subsidiaries are also referred to as
Mellon, the Corporation, we or our.



Mellons strategy is to capitalize on growth opportunities in asset management and securities services and to maintain leading positions in our payments services businesses. This attractive mix of fee-based businesses allows us to
leverage technology and sales; to achieve low risk earnings; and to aggressively manage capital for high returns. Our goal is to be the best performing asset management, payments and securities services company. Our long-term financial goals are to
achieve earnings per share growth of 11% to 14% and returns on common shareholders equity in excess of 20%, on a continuing operations basis.



We have chosen to be in certain businesses  institutional asset management, mutual funds, private wealth management, asset servicing, payment solutions &
investor services, and treasury services  that we believe are compatible with our strategy and goals. Our reasons follow.



| |  |  | Demand for our products and services is likely to be driven by existing market and demographic trends (such as the growth in worldwide retirement and financial assets; the growth
and concentration of the wealth segments; global growth in assets managed by financial institutions, particularly in the US and Europe; and the globalization of the investment process).
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Many of our products complement one another.
| | - |  | --------------------------------------------



| |  |  | We leverage sales, distribution and technology across our businesses for greater efficiency, which benefits our clients and Mellon.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | The revenue generated by our businesses is principally fee-based, providing us with lower risk earnings. In addition, our businesses do not require as much capital for growth as
traditional banking.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



We pursue our long-term financial goals by
focusing on organic revenue growth, expense management, exceptional quality service, successful integration of acquisitions and disciplined capital management.



Our specific objectives include:



| |  |  | a revenue growth rate exceeding the growth rate of U.S. financial assets over economic cycles;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | positive operating leverage over an economic cycle;
| | - |  | ---------------------------------------------------



| |  |  | investment spending aligned with revenue trends;
| | - |  | ------------------------------------------------



| |  |  | tangible common equity ratio of 4.25% to 4.75%;
| | - |  | -----------------------------------------------



| |  |  | disciplined acquisition criteria and execution; and
| | - |  | ---------------------------------------------------



| |  |  | use of excess capital to support reinvestment, acquisitions, dividends and share repurchases while maintaining appropriately strong capital ratios.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



Our success in achieving our goals and objectives is influenced by economic and market
drivers. Three key drivers have impacted our domestic results in the past:



| |  |  | growth in financial assets as measured by the U.S. Federal Reserve;
| | - |  | -------------------------------------------------------------------



| |  |  | growth in nominal U.S. Gross Domestic Product (GDP); and
| | - |  | --------------------------------------------------------



| |  |  | changes in the S&P 500 Index.
| | - |  | -----------------------------



Since 1945, these measures grew at an average rate of 7% to 8%. From 1997 to 2000, they exceeded these long-term averages, and Mellon enjoyed strong revenue growth. Since
2000, however, these measures have been below their long-term averages, directly impacting our results. Similar drivers impact our businesses outside the U.S.



Specifically, the growth rate of financial assets impacts Mellons asset management and asset servicing businesses and, less so, our payment solutions &
investor services (PS&IS) business.

Fee revenue in these businesses is determined, in part, on the level of financial assets under management, custody or administration. (The growth rate of our financial
assets includes appreciation or depreciation of existing assets and net flows of new assets.)



Nominal GDP, particularly the component that measures corporate discretionary spending, impacts revenues in outsourcing-related activities in our asset servicing businesses.



Finally, although our asset management businesses manage a wide range of equity assets, the
S&P 500 Index has so far been the most representative index for estimating the sensitivity of our domestic revenues to changes in equity market levels. Local market indices, such as the Financial Times Stock Exchange (FTSE), are representative
indices for estimating the sensitivity to equity market movements of our non-U.S. asset management revenues.



How we reported results



All
information in this Quarterly Report on Form 10-Q is reported on a continuing operations basis, unless otherwise noted.



Mellons financial results, as well as our levels of assets under management, administration and custody, are impacted by the translation of financial results
denominated in foreign currencies to the U.S. Dollar. Mellon is primarily impacted by activities denominated in the British Pound, and to a lesser extent the Canadian Dollar and the Euro. If the U.S. Dollar depreciates versus these currencies, the
translation impact is a higher level of net interest revenue, fee revenue, operating expense and assets managed, administered and under custody. If the U.S. Dollar appreciates, the translated levels of net interest revenue, fee revenue, operating
expense and assets managed, administered and under custody will be lower. Throughout this report the translation impact of foreign currencies will be referred to as the effect of foreign exchange rates.

Certain amounts are presented on a
fully taxable equivalent (FTE) basis. We believe that this presentation provides comparability of amounts arising from both taxable and tax-exempt sources and is consistent with industry practice. The adjustment to an FTE basis has no impact on net
income. Throughout this report, all calculations are based on unrounded numbers.



First quarter of 2005 compared with the first quarter of 2004 and the fourth quarter of 2004



Consolidated net income in the first quarter of 2005 totaled $255 million, or $.60 per share. This compares to $245 million, or $.57 per share, in the first quarter of 2004 and $192 million, or $.46 per share, in the
fourth quarter of 2004. First quarter 2005 income from continuing operations totaled $305 million, or $.72 per share. This compares to net income from continuing operations of $247 million, or $.58 per share, in the first quarter of 2004 and $199
million, or $.47 per share, in the fourth quarter of 2004.

a net income basis was 2.80% for the first quarter of 2005, 2.13% for the fourth quarter of 2004 and 2.96% for the first quarter of 2004. Return on assets was calculated on a continuing operations basis even though the prior periods balance sheet,
in accordance with GAAP, is not restated for discontinued operations. Returns are annualized.

In March of 2005, Mellon announced an agreement to sell our Human Resources (HR) consulting practices, benefits administration and business process outsourcing businesses to Affiliated Computer Services, Inc. (ACS). As a result of this
transaction, we adopted discontinued operations accounting for the businesses being sold and have restated the income statements for all periods presented. These businesses were formerly included in the Human Resources & Investor Solutions
(HR&IS) sector. A new sector was created (Payment Solutions & Investor Services) to include the remaining business, Mellon Investor Services, from the former HR&IS sector and two businesses, global cash management (which includes
SourceNet Solutions) and Mellon Financial Markets, which were previously included in the Treasury Services sector.



The loss from discontinued operations totaled $50 million, or $.12 per share, in the first quarter of 2005, compared with $2 million, or $.01 per share, in the first
quarter of 2004 and $7 million, or $.01 per share, in the fourth quarter of 2004. Results of discontinued operations are discussed further in Note 3 of Notes to Financial Statements. Also, for a full-year 2004 income statement restated for the
impact of discontinued operations, see page 46.



In April 2005, we increased
the quarterly common stock dividend by 11% to $.20 per common share.

Fee and other revenue



Fee and other revenue of $1.061 billion in the first quarter of 2005
increased $149 million, or 16%, from $912 million in the first quarter of 2004. In the first quarter of 2005, we recorded a pre-tax gain of $197 million as equity investment revenue from the sale of our remaining non-venture capital investment in
Shinsei Bank. In the first quarter of 2004, we also recorded a pre-tax gain of $93 million from the sale of approximately 35% of this investment. Excluding these gains, fee revenue increased $45 million, or 5%, compared with the first quarter of
2004 primarily due to increases in investment management fee revenue, institutional trust and custody revenue (including securities lending revenue) and equity investment revenue, partially offset by lower payment solutions & investor services
fee revenue. The impact of acquisitions accounted for approximately $25 million of this increase.



Fee and other revenue in the first quarter of 2005 increased $169 million, or 19% (unannualized), compared to the fourth quarter of 2004. Excluding the Shinsei gain, fee revenue decreased $28 million primarily due to
a $33 million decrease in performance fees, which are included in investment management fee revenue in the table above.



Investment management fee revenue



Investment management fee revenue is dependent on the overall level and mix of assets under management and the management fees, expressed in basis points (one-hundredth
of one percent) charged for managing those assets. See pages 8 and 9 of Mellons 2004 Financial Annual Report for a further discussion of the factors that drive the levels of investment management fee revenue and the impact on investment
management fees from changes in the

S&P 500 Index and an equivalent movement in the FTSE.



Investment management fee revenue in the first quarter of 2005 increased $22 million, or 5%, compared with the first quarter of 2004, and decreased $26 million, or 6%
(unannualized), compared with the fourth quarter 2004. The increase compared with the first quarter of 2004 primarily resulted from acquisitions, improved equity markets and net inflows, partially offset by a $12 million decrease in performance
fees. The effect of acquisitions accounted for approximately $20 million of the increase. The decrease compared with the fourth quarter of 2004 primarily resulted from a $33 million seasonal decrease in performance fees. Our investment managers
often have the opportunity to earn performance fees when the investment performance of their products exceeds various benchmarks. These fees are generally highest in the fourth quarter when most annual computation periods end. The first quarter is
generally the next highest period. Excluding the impact of performance fees, investment management fee revenue increased 9% compared to the first quarter of 2004 and 2% (unannualized) compared to the fourth quarter of 2004.

The largest category of investment
management fees are fees from mutual funds, which generate fees in the Mutual Funds and Institutional Asset Management sectors. Investment management fees from managed mutual funds are based on the daily average net assets of each fund and the basis
point management fee paid by that fund. Managed mutual fund fees totaled $176 million in the first quarter of 2005, a $1 million increase compared with the first quarter of 2004 and a decrease of $4 million, or 2% (unannualized), compared with the
fourth quarter of 2004. Compared with the first quarter of 2004, the impact of improved equity markets was primarily offset by net outflows of money market and fixed income funds. The decrease compared with the fourth quarter of 2004 resulted in
part from fewer days in the first quarter of 2005.

Institutional trust and custody fee
revenue



Institutional trust and custody fees depend on:



| |  |  | the volume of transactions in our clients accounts;
| | - |  | ----------------------------------------------------



| |  |  | the types of ancillary services we provide, such as performance analytics; and
| | - |  | ------------------------------------------------------------------------------



| |  |  | the level of assets administered and under custody.
| | - |  | ---------------------------------------------------



Institutional trust and custody fees also include securities lending revenue as well as professional and license fees for software products offered by Eagle Investment
Systems that are dependent on discretionary spending decisions by investment managers. Institutional trust and custody revenue, including securities lending revenue, increased $20 million, or 14%, in the first quarter of 2005 compared with the first
quarter of 2004, and $11 million, or 8% (unannualized), compared to the fourth quarter of 2004. Excluding securities lending revenue, the increase compared with the first quarter of 2004 primarily resulted from net new business, improved market
conditions and the acquisition of DPM, while the increase compared with the fourth quarter of 2004 resulted in part from the DPM acquisition. Securities lending revenue totaled $24 million in the first quarter of 2005, an increase of $6 million
compared with both the first and fourth quarters of 2004. The increase in securities lending revenue compared with the first quarter of 2004 reflects higher volumes and improved spreads while the increase compared with the fourth quarter of 2004
reflects improved spreads and higher volumes. The average level of securities on loan totaled $103 billion in the first quarter of 2005 compared with $83 billion in the first quarter of 2004 and $92 billion in the fourth quarter of 2004.



As shown in the following table, assets under administration or custody totaled $3.293
trillion at March 31, 2005, an increase of $469 billion, or 17%, compared with $2.824 trillion at March 31, 2004 and an increase of $60 billion, or 2% (unannualized), compared with $3.233 trillion at Dec. 31, 2004. The increase compared with March
31, 2004 primarily resulted from net new business conversions and market appreciation.

Payment solutions & investor services fee revenue



Payment
solutions & investor services fee revenue, which consists of cash management and shareholder services revenue, and other fees earned by Mellon Financial Markets and SourceNet Solutions, totaled $136 million in the first quarter of 2005, a
decrease of $11 million compared with the first quarter of 2004 and $4 million compared with the fourth quarter of 2004. The decreases primarily resulted from lower shareholder services revenue due to a lower level of activity, offset in part by the
impact of the SourceNet acquisition.



Foreign exchange trading revenue



Foreign exchange trading revenue totaled $54 million in the first quarter
of 2005, a $3 million, or 5%, decrease compared with the first quarter of 2004 and a $13 million, or 30% (unannualized), increase compared with the fourth quarter of 2004. The decrease compared with the first quarter of 2004, which was a record
level, resulted from lower spreads driven by reduced volatility in key exchange rates offset, in part, by higher client volumes. The increase compared with the fourth quarter of 2004 resulted from increased customer flows and marginally higher
levels of market volatility in key exchange rates.



Financing-related
revenue



Financing-related revenue primarily includes: returns from
corporate-owned life insurance; gains or losses on securitizations; letters of credit and acceptance fees; loan commitment fees; and gains or losses on loan sales and lease residuals. Financing-related revenue totaled $32 million in the first
quarter of 2005, a decrease of $3 million compared with the first quarter of 2004 and $8 million compared with the fourth quarter of 2004. The decrease compared with the first quarter of 2004 resulted from lower loan commitment fees and returns from
corporate-owned life insurance. The decrease compared with the fourth quarter of 2004 resulted from lower gains on lease residuals and securitizations.



Equity investment revenue



Equity investment revenue includes realized and unrealized gains and losses on venture capital and non-venture capital investments. Revenue from non-venture capital
investments includes equity income from certain investments accounted for under the equity method of accounting and gains (losses) from other equity investments.

|--- | -----------------------------------------



Equity income and gains on the sale of other equity investments totaled $203 million in the first quarter of 2005 including the $197 million gain on the sale of our
remaining investment in Shinsei Bank. This compared with $97 million in the first quarter of 2004, which included the $93 million gain on the sale of approximately 35% of our investment in Shinsei Bank.



The $16 million of venture capital net gains in the first quarter of 2005 primarily resulted
from: realized gains of $8 million on direct investments, in part from the sale of an investment in the growth and buyout industry portfolio, and net positive valuation adjustments of $8 million in the direct and indirect portfolios. The $28 million
of venture capital gains in the fourth quarter of 2004 primarily resulted from net appreciation in the direct portfolio and net realized gains in the indirect portfolio.



Mellons accounting policies regarding the valuation process for venture capital investments are regarded as critical accounting
policies in that they involve significant management valuation judgements. See pages 55 and 56 of Mellons 2004 Financial Annual Report for a description of the rating categories and for a further discussion of the factors used in the valuation
process of these investments. At

March 31, 2005, approximately 60% of the direct investment portfolio was risk- rated as superior or meets expectations, the two best risk-ratings,
compared with approximately 52% at Dec. 31, 2004. Changing economic conditions and equity markets could result in further valuation changes in the future.



Other revenue



Other revenue totaled $29 million in the first quarter of 2005, compared with $26 million in the first quarter of 2004 and $36 million in the fourth quarter of 2004. Included in other revenue are expense
reimbursements from joint ventures for expenses incurred by Mellon on behalf of the joint venture totaling $19 million in the first quarter of 2005 and $18 million in both the first and fourth quarters of 2004.



Supplemental information - joint ventures



Mellon accounts for its interests in joint ventures under the equity method of accounting,
with its share of the equity income from all joint ventures recorded primarily as institutional trust and custody fee revenue. Mellons portions of gross joint venture fee revenue and expense are not included in our reported fee revenue and
operating expense. The following table presents the components of gross joint venture net income for informational purposes to show the trend of growth for our 50% owned joint ventures that are part of the Asset Servicing sector.

Net interest revenue



Net interest revenue on a fully taxable
equivalent basis totaled $121 million in the first quarter of 2005, an increase of $1 million compared with $120 million in the first quarter of 2004 and unchanged compared with the fourth quarter of 2004. The net interest margin was 1.92% in the
first quarter of 2005 compared with 2.16% in the first quarter of 2004 and 1.93% in the fourth quarter of 2004. The increase in net interest revenue in the first quarter of 2005 compared with the first quarter of 2004 resulted from a higher level of
average interest-earning assets in the first quarter of 2005 primarily offset by the impact of a lower net interest margin. Net interest revenue was unchanged compared with the fourth quarter of 2004 as the impact of a higher level of
interest-earning assets was offset by the impact of two fewer days in the first quarter of 2005. For an analysis of the changes in volumes and rates affecting net interest revenue, see the following page.



Net interest revenue is expected to be in a $120 million to $125 million range on a fully
taxable equivalent basis for the second quarter 2005, assuming a gradual and measured increase in interest rates and allowing for tactical investment securities decisions.

Note: Interest and average yields/rates were calculated on a taxable equivalent basis, at tax rates approximating 35%, using dollar
amounts in thousands and actual number of days in the years, and are before the effect of reserve requirements. Loan fees, as well as nonaccrual loans and their related income effect, have been included in the calculation of average yields/rates.

Staff expense



Given Mellons mix of fee-based businesses and their dependence on high quality talent, staff expense comprised approximately 59% of
total operating expense in the first quarter of 2005. Staff expense is comprised of:



| |  |  | compensation expense
| | - |  | --------------------



| |  |  | base salary expense, primarily driven by headcount
| | - |  | --------------------------------------------------



| |  |  | the cost of temporaries and overtime
| | - |  | ------------------------------------



| |  |  | severance expense;
| | - |  | ------------------



| |  |  | incentive expense
| | - |  | -----------------



| |  |  | additional compensation earned under a wide range of sales commission plans and incentive plans designed to reward a combination of individual, line of business and corporate
performance versus goals
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | stock option expense; and
| | - |  | -------------------------



| |  |  | employee benefits expense
| | - |  | -------------------------



| |  |  | primarily health and welfare benefits, payroll taxes and retirement benefits.
| | - |  | -----------------------------------------------------------------------------



Non-staff expenses



Non-staff expenses include certain expenses that vary with the levels of business activity, productivity initiatives undertaken, changes in business strategy and changes in the mix of business. These expenses include:



| |  |  | professional, legal and other purchased services;
| | - |  | -------------------------------------------------



| |  |  | business development (travel, entertainment and advertising);
| | - |  | -------------------------------------------------------------



| |  |  | communications expense (telecommunications, postage and delivery); and
| | - |  | ----------------------------------------------------------------------



| |  |  | other expense (government assessments, forms and supplies, operational errors, etc.).
| | - |  | -------------------------------------------------------------------------------------



First quarter 2005 compared with first quarter 2004



Summary - Operating expense increased $43 million, or 6%, compared with the first quarter of 2004. The first quarter of 2005 included
a $10 million charge (included in other expense) for the early extinguishment of debt and $5 million of additional expense ($2 million of occupancy expense and $3 million of other expense) related to charges recorded in 2004 for the move to the new
Mellon Financial Centre in London and a writedown of one of two small non-strategic businesses previously identified as held for sale. The first quarter of 2004 included a $19 million charge for the writedown of those two businesses, one of which
was sold in 2004. See pages 15 and 16 for a reconciliation of revenue and expense amounts presented in accordance with GAAP to adjusted non-GAAP revenue and expense amounts, which exclude those items. Excluding these charges, operating expense
increased $47 million, or 7%, compared with the first quarter of 2004 reflecting a number of factors discussed below, including approximately $20 million from acquisitions.



Staff expense - Staff expense in the first quarter of 2005 increased $33 million, or 9%, compared with the first quarter of 2004,
primarily the result of: higher compensation expense reflecting the impact

of acquisitions ($13 million) and July 1, 2004 merit increases; higher employee benefits
expense due in part to higher pension expense and higher payroll taxes; and higher incentive expense. The increase in incentive expense resulted from fee-based business growth and a $2 million increase in stock option expense. Employee benefits
expense included a $6 million increase in pension expense in the first quarter of 2005 compared with the first quarter of 2004. Net periodic pension expense was $5 million, on a continuing operations basis, in the first quarter of 2005 compared with
a net pension credit of less than $1 million in the first quarter of 2004.



Non-staff expenses - Non-staff expenses in the first quarter of 2005 totaled $292 million, a $10 million, or 4%, increase compared with the first quarter of 2004. Excluding the $15 million of charges recorded in the first quarter of
2005 and the $19 million charge in the first quarter of 2004 mentioned above, non-staff expenses increased $14 million, or 5%, primarily reflecting higher professional, legal and other purchased services and higher other non-staff expenses. The
expense increases resulted in part in support of business growth and from acquisitions.



First quarter 2005 compared with fourth quarter 2004



Staff
expense in the first quarter of 2005 decreased $13 million, or 3% (unannualized), compared with the fourth quarter of 2004 resulting from lower compensation expense due to a decrease in severance expense, as well as lower incentive expense,
partially offset by higher employee benefits expense, due to higher pension expense, payroll taxes and health benefits expense. Severance expense totaled $2 million in the first quarter of 2005 compared with $17 million in the fourth quarter of
2004. The decrease in incentive expense resulted from a lower level of performance fees, partially offset by a $2 million increase in stock option expense. Employee benefits expense included a $6 million increase in pension expense in the first
quarter of 2005 compared with the fourth quarter of 2004. Non-staff expenses increased $1 million in the first quarter of 2005 compared with the fourth quarter of 2004. Excluding the $15 million of charges in the first quarter of 2005 discussed
previously and a $17 million sublease loss reserve reversal recorded in the fourth quarter of 2004, non-staff expenses decreased $31 million, or 10%. This decrease primarily reflects the $11 million loss associated with the trade execution of
securities recorded in the fourth quarter of 2004, as well as lower professional, legal and other purchased services and other non-staff expenses, due in part to two fewer days in the first quarter of 2005.



In April 2005, the Securities and Exchange Commission announced that companies may delay the
adoption of SFAS No. 123 (Revised 2004), Share-Based Payment from the current required adoption date of July 1, 2005, until January 1, 2006. A discussion of this accounting standard, which relates to share-based payments, including the
expensing of stock options, is presented on page 50 of our 2004 Financial Annual Report. Adoption of this accounting standard on July 1, 2005 would have increased stock option expense by approximately $3 million in 2005, primarily due to expensing
nonvested ShareSuccess options which were granted prior to 2003. We now intend to adopt this accounting standard on January 1, 2006. Based on options granted and not yet vested at March 31, 2005, stock option expense, on a continuing operations
basis, under the current provisions of SFAS 123, will be approximately $26 million pre-tax in 2005 and would have been approximately $24 million pre-tax in 2006. However, stock option expense for options granted and not yet vested at March 31, 2005,
under SFAS 123 (Revised 2004) will increase to approximately $29 million pre-tax in 2006, primarily due to expensing the nonvested ShareSuccess options.

Income taxes



The provision for income taxes from continuing
operations totaled $161 million in the first quarter of 2005 compared with $118 million in the first quarter of 2004 and $88 million in the fourth quarter of 2004. Mellons effective tax rate on income from continuing operations was
approximately 34.5% for the first quarter of 2005, compared with approximately 32.25% for the first quarter of 2004, approximately 30.5% for the fourth quarter of 2004 and approximately 31% for the full-year 2004. The 2004 effective tax rate
included the favorable resolution of certain federal and state income tax issues. It is currently anticipated that the effective tax rate for the second quarter and full-year 2005 will be approximately 34%.



The Internal Revenue Service (IRS) has proposed to disallow tax deductions related to
Mellons participation in several lease-in-lease-out (LILO) transactions for years 1997-2000. We believe that we reported the tax effects of LILO transactions properly based on statutes, regulations and case law in effect at the time they were
negotiated. We are currently at IRS Appeals for these years. Although the IRS has indicated that it will consider settling this issue with taxpayers, it is unclear whether a settlement will be reached. However, we believe we have adequately accrued
for any tax and interest exposures related to LILO transactions.



The FASB is
currently reviewing the impact under SFAS No. 13 of the change in tax-related cash flows due to LILO transaction settlements with the IRS. It is possible that a resolution with the IRS could result in a cumulative change in the related income
recorded on these transactions. We will continue to monitor FASB proceedings. At this time, it is neither possible to predict what changes the FASB might propose nor estimate the financial statement impact to Mellon.

Business sectors



Mellons business sectors reflect our management structure, the characteristics of our products and services, and the classes of
customers to which those products and services are delivered. Our lines of business serve two distinct major classes of clientscorporations and institutions and high net worth individuals. Lines of business that offer similar or related
products and services to common or similar client decision makers have been combined into six business sectors.



In the first quarter of 2005, we realigned our business sectors following the announcement of the signing of a definitive agreement to sell our HR consulting practices,
benefits administration, and business process outsourcing businesses. These businesses were formerly included primarily in the HR&IS sector. As a result, the new Payment Solutions & Investor Services (PS&IS) sector was created,
consisting of the remaining business, Mellon Investor Services, from the former HR&IS sector and two businesses, global cash management (which includes SourceNet Solutions) and Mellon Financial Markets, which were previously included in the
Treasury Services sector. In addition, the Treasury Services/Other Activity sector was realigned to include the remaining Treasury Services businesses as well as the results formerly included in the Other Activity sector. The realignment of the
sectors had a minor impact on the Institutional Asset Management and Mutual Funds sectors.

##### Table of Contents

The results of our business sectors are presented and analyzed on an internal management reporting basis. Revenue amounts reflect fee revenue generated directly by each sector, as well as fee revenue transferred between sectors under
revenue transfer agreements, with net interest revenue generated directly by or allocated to the sector. The accounting policies of the business sectors are the same as those described in Note 1 of Mellons 2004 Financial Annual Report except:
other fee revenue and net interest revenue differ from the amounts shown in the Consolidated Income Statement because amounts presented in Business Sectors are on a fully taxable equivalent basis (FTE); and credit quality expense (revenue) for the
sectors is presented on a net charge-off (recovery) basis, including the Treasury Services component of the Treasury Services/Other Activity sector. In the first quarter of 2005, we further refined our capital allocations to our Asset Management and
Payments and Securities Services business sectors to better reflect credit risk, operating risk, market risk and strategic risk inherent in those businesses and the required economic capital to reflect those risks, at a 99.97% confidence level. The
decrease in allocated capital was approximately $150 million versus the amount that would have been allocated using prior methodologies.



The Business Sector information is reported on a continuing operations basis for all periods presented. See Note 3 of this report for a discussion of discontinued
operations.



Following is a discussion of Mellons six business sectors.
In the tables that follow, the income statement amounts are presented in millions and are on an FTE basis, the assets under management, administration or custody are period-end market values and are presented in billions, and the return on common
equity is annualized. Where applicable and when possible, revenue and expense growth rates are reported excluding the impact of acquisitions, divestitures or the formation of joint ventures to improve period to period comparability. The operations
of acquired businesses are integrated with the existing business sectors soon after most acquisitions are completed. As a result of the integration of staff support functions, management of customer relationships, operating processes and the
financial impact of funding the acquisitions, we cannot accurately determine the impact of acquisitions on income before taxes and therefore do not report it.



See pages 22 through 28 of Mellons 2004 Financial Annual Report for a discussion of the products and services offered, the distribution channels for the products
and services and the factors that drive the performance of the Institutional Asset Management, Mutual Funds, Private Wealth Management & Asset Servicing sectors. The Payment Solutions & Investor Services and Treasury Services/Other Activity
sectors are discussed below.

Institutional Asset Management is comprised of Mellon Institutional Asset Management (MIAM),
which consists of a number of asset management companies offering a broad range of equity, fixed income, hedge and liquidity management products; and Mellon Global Investments (MGI), which distributes investment management products internationally.



The $26 million, or 13%, increase in revenue in the first quarter of 2005
compared with the first quarter of 2004 primarily resulted from an increase in investment management fees, primarily due to the impact of acquisitions, improved equity markets and net inflows, partially offset by a $12 million decrease in
performance fees. As shown in the table on page 18, assets under management for this sector, before amounts subadvised for other sectors, increased $51 billion from March 31, 2004, resulting from $31 billion of net inflows, $15 billion of market
appreciation and $5 billion from acquisitions. Operating expense increased $24 million, or 17%, primarily as a result of acquisitions. The decrease in the pre-tax operating margin compared with the first quarter of 2004 resulted from lower high
margin performance fees and acquisitions. Income before taxes increased $2 million, or 3%, compared with the first quarter of 2004.



Results for the first quarter of 2005 compared with the fourth quarter of 2004 reflect a $1 million, or 2% (unannualized), increase in income before taxes as a $24
million, or 9% (unannualized), decrease in revenue was more than offset by a $25 million, or 14% (unannualized), decrease in expense. The decrease in revenue resulted from a $33 million seasonal decrease in performance fees. The decrease in expense
reflects the $11 million loss associated with the trade execution of securities recorded in the fourth quarter of 2004 and lower incentive expense. The pre-tax operating margin improved compared with the fourth quarter of 2004 as the expense
decreases mentioned above more than offset a decrease in performance fees. As shown in the table on page 18, assets under management for this sector, before amounts subadvised for other sectors, increased $20 billion, or 4% (unannualized), from Dec.
31, 2004, primarily due to money market and securities lending inflows, partially offset by the impact of market depreciation.

Income before taxes for this sector decreased $8 million, or 17%, in the first quarter of 2005 compared with the first quarter of 2004. Total revenue decreased $9
million, or 7%, reflecting lower average levels of institutional cash management funds due to net outflows. The $1 million decrease in operating expense primarily resulted from lower incentives and other expenses. The decrease in the pre-tax
operating margin compared with the first quarter of 2004 reflects the factors mentioned above. Assets under management for this sector, before amounts subadvised for other

sectors, of $160 billion were down 2% from $163 billion at March 31, 2004, resulting from institutional cash management outflows.



Results for the first quarter of 2005 compared with the fourth quarter of 2004 reflect a $4 million, or 10% (unannualized), decrease in income before taxes as the impact
of a $6 million, or 5% (unannualized), decrease in revenue more than offset a $2 million, or 3% (unannualized), decrease in expense. The decrease in revenue was due mainly to fewer days in the first quarter of 2005. The decrease in expense resulted
from lower expenses in several categories, including incentives. The decrease in pre-tax operating margin compared with the fourth quarter of 2004 reflects the factors mentioned above. Assets under management for this sector, before amounts
subadvised for other sectors, of $160 billion were up 2% from $157 billion at Dec. 31, 2004, reflecting institutional money market inflows.

Private Wealth Management provides investment management, wealth management, and
comprehensive banking services for high net worth individuals, families, family offices, charitable gift programs, endowments, foundations, professionals and entrepreneurs. It operates from more than 60 locations in 15 states.



Income before taxes for this sector increased $7 million, or 11%, in the first quarter of
2005 compared with the first quarter of 2004, as a $10 million, or 7%, increase in revenue more than offset a $3 million, or 5%, increase in expense. The increase in revenue resulted from higher investment management fee revenue, primarily due to
the impact of improved equity markets, net new business and acquisitions. Higher net interest revenue also contributed to the increase in revenue. The increase in expense primarily resulted from business growth and acquisitions. The pre-tax margin
increased to 44% due to positive operating leverage. Client assets increased $1 billion from March 31, 2004, primarily reflecting the impact of acquisitions and equity market appreciation.



Results for the first quarter of 2005 compared to the fourth quarter of 2004 reflect a $12
million, or 23% (unannualized), increase in income before taxes, resulting from a $9 million, or 7% (unannualized), increase in revenue and positive operating leverage. The increase in revenue resulted from higher net interest revenue and higher fee
revenue from net new business and acquisitions. The $3 million, or 3% (unannualized), decrease in expense mainly reflects lower marketing, travel and professional consulting expenses partially offset by higher incentive expense. Client assets were
$77 billion at March 31, 2005, a decrease of $1 billion from Dec. 31, 2004, reflecting the impact of equity market depreciation.

outsourcing, performance measurement, benefits disbursements, transition management, fund administration, Web-based investment management software and foreign exchange and derivative products.



Income before taxes for this sector increased $4 million, or 9%, in the first quarter of 2005
compared with the first quarter of 2004, driven by a $21 million, or 10%, increase in revenue and slightly positive operating leverage. The increase in revenue was due to higher institutional trust and custody revenue from net new business, improved
market conditions, higher securities lending revenue and the DPM acquisition, as well as from higher net interest revenue. The $17 million, or 10%, increase in operating expense resulted from business growth and the acquisition. Assets under
administration or custody for this sector were $3.259 trillion at March 31, 2005, an increase of $466 billion, or 17%, compared with March 31, 2004. The increase compared with March 31, 2004, resulted from net new business conversions and market
appreciation.



Results for the first quarter of 2005 compared with the fourth
quarter of 2004 reflect a $15 million, or 38% (unannualized), increase in income before taxes, driven by a $19 million, or 9% (unannualized), increase in revenue and strong positive operating leverage. The increase in revenue was primarily the
result of higher foreign exchange trading revenue as well as institutional trust and custody revenue, reflecting higher securities lending revenue and the impact of an acquisition. The $4 million, or 2% (unannualized), increase in operating expense
resulted from business growth and acquisitions. Assets under administration or custody increased $60 billion, or 2% (unannualized), compared with Dec. 31, 2004, reflecting net new business conversions and an acquisition, partially offset by market
depreciation.

The Payment Solutions & Investor
Services sector includes:



| |  |  | Global cash management (GCM) - The results of GCM are driven by transaction activity including automated clearinghouse, wire transfer and telecash; remittance processing services,
primarily wholesale/custom and retail lockbox; and ancillary processing services for check clearing, imaging and storage activities. The other significant driver to GCMs results is net interest revenue earned from the deposit balances
generated by activity across the business operations;

| |  |  | Mellon Investor Services provides shareholder services that consist of a diverse array of products to shareholders and corporations including stock transfer and recordkeeping
services, investment plan services, demutualizations, corporate actions and unclaimed property services;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | SourceNet, which offers accounts payable and other business processing; and
| | - |  | ---------------------------------------------------------------------------



| |  |  | Mellon Financial Markets, our full-service broker-dealer subsidiary.
| | - |  | --------------------------------------------------------------------



Within the Payment Solutions & Investor Services business sector, investor services revenue includes earnings related to customer deposit balances maintained in an
agency capacity. Customer balances held in an agency capacity and not reflected on Mellons balance sheet totaled $507 million at March 31, 2005.



Income before taxes for this sector decreased $8 million, or 16%, in the first quarter of 2005 compared with the first quarter of 2004, resulting from higher expenses.
Revenue was unchanged as cash management results, including the net interest revenue earned from customers who pay for services with compensating deposit balances, increased 5%, plus the impact of the SourceNet acquisition, was offset by lower
investor services revenue, which included additional high margin ancillary revenue in the first quarter of 2004. The $8 million, or 7%, increase in expense mainly resulted from higher staff expense as well as the impact of the SourceNet acquisition.



Results for the first quarter of 2005 compared with the fourth quarter of 2004
reflect a $4 million, or 11% (unannualized), increase in income before taxes driven by a $3 million, or 2% (unannualized), increase in revenue and positive operating leverage. The increase in revenue was primarily due to higher cash management
revenue, the SourceNet acquisition and higher net interest revenue, partially offset by lower investor services fees. Operating expense for the sector decreased primarily due to lower processing volumes.



Treasury Services/Other Activity



As discussed on page 28, the global cash management and Mellon Financial Markets businesses
were moved from the Treasury Services sector to the PS&IS sector. The current Treasury Services activities include:



| |  |  | credit products for large corporations;
| | - |  | ---------------------------------------



| |  |  | insurance premium financing (AFCO);
| | - |  | -----------------------------------



| |  |  | commercial real estate lending; and
| | - |  | -----------------------------------



| |  |  | the activities of Mellon 1stBusiness Bank,
National Association, in California.
| | - |  | -------------------------------------------------------------------------------



Other Activity includes:



| |  |  | business exits activity, including;
| | - |  | -----------------------------------



| |  |  | the results of large ticket leasing, which is in a runoff mode;
| | - |  | ---------------------------------------------------------------



| |  |  | several small non-strategic businesses;
| | - |  | ---------------------------------------



| |  |  | the merchant card business; and
| | - |  | -------------------------------



| |  |  | certain lending relationships that Mellon is in the process of exiting;

| |  |  | the results of Mellon Ventures, our venture capital group; and
| | - |  | --------------------------------------------------------------



| |  |  | and business activities or utilities, including Corporate Treasury, that are not separate lines of business or have not been fully allocated for management reporting purposes to the
business sectors.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



The aggregation of the current Treasury
Services activities, together with business exits activity and the results of Mellon Ventures presents the results of capital driven activities to earn net interest revenue, financing-related revenue and equity investment gains.

Revenue in the Treasury Services/Other Activity sector primarily reflects:



| |  |  | net interest revenue from loans;
| | - |  | --------------------------------



| |  |  | net interest revenue of business exits activity;
| | - |  | ------------------------------------------------



| |  |  | gains (losses) and funding costs of Mellon Ventures portfolio;
| | - |  | ---------------------------------------------------------------



| |  |  | gains (losses) from the sale of securities and other assets; and
| | - |  | ----------------------------------------------------------------



| |  |  | earnings on capital above that required for the business sectors.
| | - |  | -----------------------------------------------------------------



Operating expense includes:



| |  |  | direct expenses supporting the remaining Treasury Services activities;
| | - |  | ----------------------------------------------------------------------



| |  |  | various direct expenses for items not attributable to the operations of a business sector;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | a net credit for the net corporate level (income) expense amounts allocated from Other Activity to the business sectors; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | the expenses of Mellon Ventures.
| | - |  | --------------------------------



Assets in Treasury Services/Other Activity include assets of the activities discussed below that we intend to exit, the investments of Mellon Ventures and assets of
certain areas not identified with the asset management and payments and securities services business sectors. This sector also includes assets and liabilities recorded in Corporate Treasury and not allocated to a particular line of business. Average
common equity represents capital in excess of that required for the business sectors, as well as capital required to support Treasury Services lending activity and for the investments of Mellon Ventures and business exits.



Our credit strategy is to exit all credit relationships for which a broad fee-based
relationship resulting from the cross-sale of our fee-based services does not exist. The loans and leases included in business exits are:



| |  |  | Mellons large ticket lease portfolio, which was principally transaction-based; and
| | - |  | -----------------------------------------------------------------------------------



| |  |  | loans to companies where a broad fee-based relationship does not exist.
| | - |  | -----------------------------------------------------------------------



We will not renew these credit relationships with such companies when the respective contractual commitment periods end. We may consider selling remaining commitments on
a case-by-case basis as opportunities arise.



Results for Treasury Services
activities in the first quarter of 2005 compared with prior quarters reflect lower net interest revenue from a lower average level of loans and lower spreads.



The Treasury Services/Other Activity sector also reflects the following activity:



In the first quarter of 2005:



| |  |  | a $197 million gain from the sale of our remaining investment in Shinsei Bank;
| | - |  | ------------------------------------------------------------------------------



| |  |  | $16 million of net gains from venture capital activities;
| | - |  | ---------------------------------------------------------



| |  |  | a $10 million charge associated with the early extinguishment of debt;
| | - |  | ----------------------------------------------------------------------



| |  |  | $5 million of additional expenses related to charges initially recorded in 2004 as discussed on page 25; and
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | a $1 million negative provision for credit losses.
| | - |  | --------------------------------------------------



In the first quarter of 2004:



| |  |  | a $93 million gain from the sale of approximately 35% of our investment in Shinsei Bank;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | the $19 million charge for the writedown of two small non-strategic businesses, one of which was sold in 2004; and
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | a $7 million negative provision for credit losses.
| | - |  | --------------------------------------------------



In the fourth quarter of 2004:



| |  |  | $28 million of net gains from venture capital activities;
| | - |  | ---------------------------------------------------------



| |  |  | the $17 million sublease loss reserve reversal related to the execution of a new lease on our headquarters building in Pittsburgh; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a $4 million negative provision for credit losses.

Mellons higher total shareholders equity to assets ratio at March 31, 2005 compared with Dec. 31, 2004, reflects the impact of earnings retention. The ratio
compared with March 31, 2004 reflects the impact of a larger balance sheet. Tangible shareholders equity increased $254 million from $1.636 billion at Dec. 31, 2004. This increase primarily resulted from adopting discontinued operations
accounting for the businesses included in the former Human Resources & Investor Solutions sector and the related reduction in goodwill and intangibles, as well as from earnings retention. This change resulted in a 47 basis point increase in the
tangible shareholders equity to assets ratio. For a

discussion of our capital management policies, see page 33 of Mellons 2004 Financial
Annual Report.



The risk-based capital ratios compared with March 31, 2004
improved due to earnings retention as well as a lower level of risk-adjusted assets. The decrease in risk-adjusted assets resulted in part from a lower level of risk-adjusted assets related to a guarantee provided to the ABN AMRO Mellon custody
joint venture for securities lending activity. At March 31, 2005, that guarantee decreased our Tier I and Total capital ratios by approximately 40 basis points and 60 basis points compared with approximately 25 basis points and 40 basis points at
Dec. 31, 2004, and approximately 135 basis points and 205 basis points at March 31, 2004.



In March 2005, the Board of Governors of the Federal Reserve System (the Board) amended its risk-based capital standards for bank holding companies to allow the continued inclusion of trust-preferred securities in the
Tier I capital of bank holding companies, subject to stricter quantitative limits and qualitative standards. The Boards final rule limits trust-preferred securities taken together with certain core capital elements to 25% of core capital
elements, net of goodwill less any associated deferred tax liability, for non-internationally active banks. For internationally active bank holding companies (defined as bank holding companies with consolidated total assets of $250 billion or more,
or total on-balance sheet foreign exposure of $10 billion or more) the Board further restricts the inclusion of trust-preferred securities to 15% of core capital elements, net of goodwill less any associated deferred tax liability. The quantitative
limits become effective on March 31, 2009. Under the limitations discussed above, at March 31, 2005, Mellons risk-based capital ratios would have exceeded the well capitalized guidelines.



In October 2002, Mellons Board of Directors authorized a share repurchase program of up
to 25 million shares of common stock. During the first quarter of 2005, 1.5 million common shares were repurchased by Mellon under this publicly announced program. At March 31, 2005, an additional 8 million common shares were available for
repurchase under this program, which does not have an expiration date. Share reissuances, primarily for employee benefit plan purposes, totaled 1.7 million for the first quarter of 2005.

Composition of loan portfolio

---



The loan portfolio at March 31, 2005 increased $324 million compared with Dec. 31, 2004 and decreased $320 million compared with March 31, 2004. The increase compared
with Dec. 31, 2004, reflects higher levels of commercial and financial and international loans and leases, in part resulting from maturing insurance premium finance loan securitizations. The decrease compared with March 31, 2004 reflects lower
levels of commercial and financial loans and commercial real estate loans, partially offset by a higher level of personal loans.



At March 31, 2005, approximately 73% of the loans to our large corporate commercial and financial customers had an investment grade credit rating. Investment grade loans
and commitments are those where the customer has:



| |  |  | a Moodys long-term rating of Baa3 or better, and/or;
| | - |  | -----------------------------------------------------



| |  |  | a Standard and Poors long-term rating of BBB- or better; or

increased $56 million, or less than 1%, compared with Dec. 31, 2004 and $404 million, or 6%,
compared with March 31, 2004. The increase compared with March 31, 2004 resulted from a shift towards longer maturities of loan commitments. At March 31, 2005, approximately 98% of unfunded loan commitments to our large corporate customers had an
investment grade credit rating.



Other guarantees and indemnities



In the normal course of business, Mellon offers guarantees in support of
certain joint ventures and subsidiaries, and certain other guarantees and indemnities.



Standby letters of credit and foreign and other guarantees irrevocably obligate Mellon for a stated period to disburse funds to a third-party beneficiary if our customer fails to perform under the terms of an agreement with the beneficiary.
We must recognize, at the inception of standby letters of credit and foreign and other guarantees, a liability for the fair value of the obligation undertaken in issuing the guarantee. At March 31, 2005, we had a liability of $7 million related to
letters of credit issued or modified since Dec. 31, 2002.



A securities lending
transaction is a fully collateralized transaction in which the owner of a security agrees to lend the security through an agent (Mellon) to a borrower, usually a broker/dealer or bank, on an open, overnight or term basis, under the terms of a
prearranged contract, which generally matures in less than 90 days. Securities are lent with and without indemnification against broker default. Custodian securities lent with indemnification against broker default of return of securities totaled
$97 billion at March 31, 2005 and were primarily collateralized by cash and U.S. government securities.



For additional information on standby letters of credit and foreign and other guarantees, and custodian securities lent with indemnification against broker default of return of securities, see pages 47, 48, 102 and
103 of Mellons 2004 Financial Annual Report.



Mellon Bank, N.A. and ABN
AMRO Bank N.V. entered into a joint venture to provide global securities services, with operations commencing in January 2003. Each of the two partners signed a statutory declaration under Dutch law as of Dec. 31, 2002 to be jointly and severally
liable with the joint venture to parties that have a provable contractual debt or damage claim. The benefit of this declaration is potentially available to all creditors and customers of the joint venture with valid legal claims if the joint venture
defaults. The guarantee totaled approximately $38 billion at March 31, 2005, primarily relating to securities lending activity. Agency securities lending represents approximately $36 billion of this guarantee, primarily related to the
indemnification of the owner of the securities against broker default. These securities lending transactions are collateralized by approximately $36 billion, comprised of cash, OECD government securities and equities. This potential exposure also
assumes that there are no capital or assets of the joint venture to satisfy such claims, and that there is no level of contribution by ABN AMRO Bank N.V.



Mellon has also provided standard representations for underwriting agreements, acquisition and divestiture agreements, sales of loans and commitments, and other similar
types of arrangements and customary indemnification for claims and legal proceedings related to its provision of financial services. We have purchased insurance to mitigate certain of these risks. Mellon is a minority equity investor in, and member
of, several industry clearing or settlement exchanges through which foreign exchange, securities or other transactions settle. Certain of these industry clearing or settlement exchanges require their members to guarantee their obligations and
liabilities or to provide financial support in the event other partners do not honor their obligations. It is not possible to estimate a maximum potential amount of payments that could be required with such agreements.



Mellons primary banking subsidiary, Mellon Bank, N.A. (the Bank) has a referral
relationship with Three Rivers Funding Corp. (TRFC), a special purpose entity that issues commercial paper. TRFC is owned by an independent third party and is not a

subsidiary of either the Bank or Mellon. Its financial results are not
included in the financial statements of the Bank or Mellon. TRFC was formed in 1990 and can issue up to $5 billion of commercial paper to make loans secured by, and to purchase, pools of receivables. The Bank operates as a referral agent and refers
transactions to TRFC as well as providing all administrative services. Loans or other assets are not transferred from the Bank to TRFC. TRFC sold subordinated notes to an unrelated third party in 2003 and as a result of that sale, Mellon is not the
primary beneficiary of TRFC, as defined by FIN 46 Revised.



Fee
revenue of less than $1 million was received from this entity in each of the first quarter of 2005, fourth quarter of 2004, and first quarter of 2004, for the services and the liquidity and credit support facilities. At March 31, 2005, TRFCs
receivables totaled $421 million and commercial paper outstanding totaled $444 million compared with $623 million for each at Dec. 31, 2004. A letter of credit provided by the Bank in support of TRFCs commercial paper totaled $50 million at
both March 31, 2005 and Dec. 31, 2004. Mellons maximum loss exposure related to TRFC, which is required to be disclosed under FIN 46, is the full amount of the liquidity facility, or $444 million, at March 31, 2005. However, the probability of
this loss scenario is remote as it would mean that all of TRFCs receivables were wholly uncollectible. The facilities that provide liquidity and credit support to TRFC are included in the Off-balance-sheet financial instruments with contract
amounts that represent credit risk table on page 37. The estimated liability for losses related to these arrangements, if any, is included in the reserve for unfunded commitments. For a further discussion of our relationship with TRFC, see Note 7 of
Mellons 2004 Financial Annual Report.

is presented in the Nonperforming assets discussion and in Note 1 in our 2004 Financial Annual Report.



At March 31, 2005 loans that were 30-59 days, 60-89 days and 90 days or more past due as to principal or interest totaled $11 million, $1 million and $5 million. Loans 90
days or more past due, that are not classified as nonaccrual loans, were either well secured and in the process of collection or were personal loans that are automatically charged off upon reaching various stages of delinquency.

Provision and reserve for credit exposure



Mellons accounting policy regarding the reserve for credit exposure is regarded as a
critical accounting policy in that it involves significant management valuation judgements. For a further discussion of our accounting policy relating to the reserve for credit exposure see pages 45 and 46 of this report.



The allocation of the reserve for credit exposure is presented below. This allocation is
judgmental, and the entire reserve is available to absorb credit losses regardless of the type of loss.

The increase in the total base reserve
and the decrease in the unallocated loan loss reserve at March 31, 2005 compared with Dec. 31, 2004 was primarily driven by higher commercial and financial, and lease asset reserves due to refinement of the methodology used to determine the level of
reserves, that was implemented during the first quarter of 2005. New quantitative factors have replaced the historical loss factors and take into account the credit rating, maturity, exposure size and industry. The decrease in the
impairment/judgmental reserve is due to a lower level of impaired credits with no change to the judgmental reserve on a nonperforming leasing credit, which has been reviewed for potential loss content. The increase in the reserves for unfunded
commitments at March 31, 2005 from Dec. 31, 2004 is primarily related to the refinement of methodology used to determine the level of reserves.



Mellons management concluded that, at March 31, 2005, the overall reserve level was appropriate to recognize inherent losses in the loan portfolio.



The net provision for credit losses totaled negative $1 million in the first quarter of 2005,
compared with negative $7 million in the first quarter of 2004 and negative $4 million in the fourth quarter of 2004. There were no net credit-related losses in the first quarter of 2005 and the first quarter of 2004. Net credit recoveries totaled
$1 million in the fourth quarter of 2004, as detailed in the table below.

The increase in average
interest-earning assets in the first quarter of 2005 compared with both the first and fourth quarters of 2004 primarily resulted from higher levels of securities and money market investments, partially offset by lower levels of loans. The increase
in average securities was due to purchases of floating rate and other short duration mortgage-backed securities. The lower level of

loans was due in part to an insurance premium finance loan securitization partially offset by the maturation of securitizations. The increase in the proportion of average
core funds to average total funds supporting total assets in the first quarter of 2005 compared with the first quarter of 2004, was primarily due to higher levels of custody, cash management and private wealth deposits. See pages 42 and 43 of
Mellons 2004 Financial Annual Report for a definition of core and purchased funds.



Liquidity and dividends

---



We manage our liquidity position with the objective of maintaining the ability to fund commitments and to repay liabilities in accordance with their terms, even during
periods of market or financial stress. Through active liquidity management, we seek to ensure that changes in funding requirements can be accommodated without materially impacting net income. Core demand and time deposits, gathered from our private
wealth management, asset servicing and PS&IS businesses, are used in conjunction with long-term debt to provide stable sources of funding. Purchased funds, acquired from a variety of sources and customers in worldwide financial markets, are used
to supplement the core sources of funding. Liquid assets, in the form of money market investments and portfolio securities held available for sale, are also utilized to meet short-term requirements for cash. Liquidity is managed on both a
consolidated basis and at the Mellon Financial Corporation (Parent Corporation) level.



The Parent Corporation has access to the following principal sources of liquidity: dividend and interest payments from its subsidiaries, the commercial paper market, a revolving credit agreement with Mellon Bank, N.A., and access to the
capital markets. The ability of national bank subsidiaries to pay dividends to the Parent Corporation is subject to certain regulatory limitations, as discussed in Note 24 of Mellons 2004 Financial Annual Report. Under the more restrictive
limitation, Mellons national bank subsidiaries can, without prior regulatory approval, declare dividends subsequent to March 31, 2005 of up to approximately $365 million, less any dividends declared and plus or minus net profits or losses, as
defined, earned between April 1, 2005 and the date of any such dividend declaration. To comply with regulatory guidelines, Mellon and its subsidiary banks continually evaluate the level of cash dividends in relation to their respective operating
income, capital needs, asset quality and overall financial condition.



At March
31, 2005, the Parent Corporation had $568 million of unencumbered liquid assets. The Parent Corporation has a $200 million revolving credit agreement with Mellon Bank, N.A., Mellons primary bank subsidiary, with a June 2005 expiration date.
The agreement was executed at market terms. Under this agreement any borrowings are to be collateralized with eligible assets of our non-bank subsidiaries. There were no borrowings under this facility during the first quarter of 2005 or at March 31,
2005. The Parent Corporation also has the ability to access the capital markets with $1.45 billion of unused capacity to issue debt, equity and junior subordinated debentures under a shelf registration statement. Access to the capital markets is
partially dependent on Mellons and Mellon Bank, N.A.s credit ratings which are shown in the following table.

Contractual maturities of
Mellons long-term debt totaled approximately $100 million in the first quarter of 2005. Contractual maturities will total approximately $550 million for the remainder of 2005.



In March 2005, we repurchased and retired approximately $118 million of previously issued subordinated notes of Mellon Bank, N.A., due 2007,
with a coupon rate of 7.625%. We recorded a pre-tax charge of $10 million on this transaction in the first quarter of 2005.



We paid $76 million in common stock dividends in the first quarter of 2005 compared with $68 million

in the first quarter of 2004. The common dividend payout ratio, on a net income basis, was 30% in the first quarter of 2005 on a dividend of $.18 per share compared with 28% in the first quarter of 2004 on a dividend of $.16 per share. On
April 19, 2005, we announced a $.02, or 11%, increase in our quarterly common stock dividend rate to $.20 per share. Based upon shares outstanding at March 31, 2005 and the current quarterly common stock dividend rate of $.20 per share, the annual
common stock dividend is expected to be approximately $340 million.



As shown
in the consolidated statement of cash flows, cash and due from banks increased by $28 million during the first three months of 2005 to $2.803 billion. The increase resulted from $336 million of net cash provided by financing activities and $90
million of net cash provided by operating activities, partially offset by $350 million of net cash used in investing activities. Net cash provided by financing activities primarily resulted from higher levels of deposits, federal funds purchased and
other funds borrowed, partially offset by repayments of longer-term debt. Net cash used in investing activities primarily resulted from a higher level of securities available for sale and loan advances, partially offset by a lower level of federal
funds sold.



Interest rate sensitivity analysis

---



Interest rate risk is measured using net interest
revenue simulation and portfolio equity simulation analyses. The following table illustrates the simulation analysis of the impact of a 50, 100 and 200 basis point shift upward or 50 and 100 basis point shift downward in short-term interest rates on
net interest revenue, earnings per share and return on equity. Given the relatively low interest rate environment that existed at March 31, 2005, the impact of a 200 basis point downward shift is not shown in the table. This analysis was prepared
using the levels of all interest-earning assets, supporting funds and derivative instruments used for interest rate risk management at March 31, 2005. The impact of the rate movements was developed by simulating the effect of rates changing in a
gradual fashion over a six-month period from the March 31, 2005 levels and remaining at those levels thereafter. Financial market conditions and managements response to events may cause actual results to differ from simulated results.
Additional information regarding Mellons interest rate risk management is presented in the Interest rate sensitivity analysis discussion on pages 44 through 46 in Mellons 2004 Financial Annual Report.

The anticipated impact on net interest
revenue under the various scenarios did not exceed our guidelines for assuming interest rate risk at both March 31, 2005 and March 31, 2004.



Managing interest rate risk with derivative instruments



Derivatives are used as part of the Mellons overall asset/liability management process to augment the management of interest rate exposure. The total notional
amount of interest rate swaps used to manage interest rate risk was $3.082 billion at March 31, 2005, compared with $3.084 billion at Dec. 31, 2004 and $2.476 billion at March 31, 2004. The increase compared with March 31, 2004, primarily resulted
from entering into instruments in conjunction with long-term debt issuances in 2004. The notional value at March 31, 2005 was primarily comprised of receive fixed instruments associated with long-term debt and junior subordinated debentures with a
weighted average maturity of approximately 9 years and weighted average interest rates received and paid of 5.57% and 3.02%, respectively. The net interest differential between interest revenue and interest expense resulted in interest revenue of
$29 million in the first quarter of 2005, compared with interest revenue of $37 million in the first quarter of 2004. Additional information

regarding these contracts is presented in Note 27 in Mellons 2004 Financial Annual Report.



We enter into interest rate swaps designated as fair value hedges, to convert portions of our fixed rate junior subordinated debentures to
floating rate securities, our fixed rate long-term debt to floating rate debt and, to a small degree, certain fixed rate loans to variable rate loans. The fixed rate liability instruments are changed to variable rate instruments by entering into
receive fixed/pay variable swaps, and the fixed rate asset instruments are changed to variable rate instruments by entering into pay fixed/receive variable swaps. No ineffectiveness was recorded for the three months ended March 31, 2005 and March
31, 2004. At March 31, 2005, there were no outstanding cash flow hedges.



Derivative instruments used for trading purposes

---



Mellon enters into various foreign exchange and interest rate derivative contracts for trading purposes. Trading activities primarily involve providing various derivative
products to customers to assist them in managing foreign currency exchange risk, interest rate risk and equity price risk and for managing our risks in certain trading portfolios and as part of our proprietary trading activities. All of these
instruments are carried at market value with realized and unrealized gains and losses included in foreign exchange trading revenue and other revenue. Additional information regarding these contracts is presented in Mellons 2004 Financial
Annual Report on pages 46 and 47 and in Note 27.

We use a value-at-risk methodology to
estimate the potential gain or loss in a portfolio of trading positions that is associated with a price movement of given probability over a specified time frame. Using our methodology, which considers such factors as changes in currency exchange
rates, interest rates, spreads and related volatility, the aggregate average value-at-risk for trading activities and credit default swaps was approximately $5 million for the 60 business-day period ending March 31, 2005, compared with $5 million
for the 60 business-day period ending Dec. 31, 2004 and approximately $4 million for the 60 business-day period ending March 31, 2004.

Critical accounting policies



Our significant accounting
policies are discussed in Note 1 in Mellons 2004 Financial Annual Report. Our critical accounting policies are those related to valuing venture capital investments, provision and reserve for credit exposure, and accounting for pensions. For a
discussion of the policies on valuing venture capital investments and accounting for pensions, see pages 55 through 57 and pages 93 and 94 of Mellons 2004 Financial Annual Report. In the first quarter of 2005, we refined our methodology used
to determine the provision and level of reserve for credit exposure, as discussed below.



Provision and reserve for credit exposure



Mellons banking subsidiaries maintain a reserve for loan losses that is intended to adjust the value of their loans for inherent credit losses. The banking subsidiaries also maintain a reserve for unfunded commitments, namely loan
commitments, letters of credit and bankers acceptances, that is reported as a liability on Mellons consolidated balance sheet. Provision to expense is recorded for each reserve. Transfers between the reserves can occur in conjunction with
funding a loan and thereby decreasing unfunded commitments or conversely repaying a loan and thereby increasing unfunded commitments. The level of the reserve for unfunded commitments is determined following a methodology similar to that used for
the reserve for loan losses. Mellon refers to the combined balance of the reserve for loan losses and the reserve for unfunded commitments as the reserve for credit exposure.



The reserve for credit exposure is maintained at a level that, in managements judgment, is sufficient to absorb losses inherent in
both the loan portfolio and in unfunded commitments as of the balance sheet date. The reserve is not specifically associated with individual loans or portfolio segments and is therefore available to absorb credit losses arising from any portfolio
segment. We review the appropriateness of each reserve at least quarterly and have developed a methodology designed to provide a procedural discipline in assessing the appropriateness of the reserves. Our estimate of each reserve component is based
on certain observable data that we believe are the most reflective of the underlying credit losses being estimated.



A key element of the methodology for determining the level of the reserve for credit exposure is Mellons credit risk evaluation process, which assigns a numerical
risk rating to substantially all extensions of credit in our commercial, real estate, and international portfolios. The Customer Risk Rating evaluates a borrowers expected ability to meet its obligations, through analysis of its financial
statements and projections, cash flow, management, and other customer risk factors. The Facility Risk Rating defines the risk of a specific credit facility by overlaying the Customer Risk Rating with an analysis of factors such as loan structure and
collateral.



In accordance with SFAS No. 5, Accounting for
Contingencies, we provide a base reserve for commercial facilities which are not impaired. We have analyzed historical portfolio data on our primary credit exposure portfolios as well as various benchmarks to compute the probability of
default, loss given default and exposure at default. Based on the risk rating, maturity, exposure size and industry of our current portfolio and the above calculated parameters, base rates are determined and applied to all non-impaired
commercial loan balances. On at least an annual basis, all credit parameters will be validated and updated.



In accordance with SFAS No. 114, Accounting by Creditors for Impairment of a Loan, any required impairment reserves are included in the reserve for loan losses. Using Mellons credit risk
classification criteria, loan impairment on specific loans, for which principal and interest is not expected to be collected when contractually due, is measured based on observable market prices, the present value of expected future cash flows
discounted at the loans effective interest rate, or the fair value of the collateral if the loan is collateral dependent with consideration being given to Mellons collection strategy. There are no base reserves carried on loans
classified as impaired. Leasing credits, which are not subject to SFAS

No. 114, follow the same criteria as impaired loans but the reserves are classified as
judgmental.



The methodology for determining the reserve for unfunded
commitments parallels the reserve for loan losses. We incorporate an estimate of probability of drawdown, which is applied to the commitment amount and then the base rates used for outstanding loans of the same credit risk rating are applied.



In addition to the components identified, management judgment can be applied
to the reserve calculation, which is based upon a quarterly assessment conducted to identify the current stage of the business cycle. As such, Mellons reserve for credit exposure is solely an estimate based on our judgment. Due to the
significance of our judgment used to calculate Mellons reserves, actual losses incurred could be higher or lower than the estimated reserves. When losses on specific loans or commitments are identified, we charge off the portion deemed
uncollectible.

Item 4. Controls and Procedures



---



The Corporations management, with the participation of its principal executive officer and principal financial officer, has evaluated
the effectiveness, as of March 31, 2005, of the Corporations disclosure controls and procedures, as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act). Based
upon their evaluation, the principal executive officer and principal financial officer concluded that the Corporations disclosure controls and procedures, as of March 31, 2005, were effective to provide reasonable assurance that information
required to be disclosed by the Corporation in the reports filed or submitted by it under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commissions rules and
forms, and to provide reasonable assurance that information required to be disclosed by the Corporation in such reports is accumulated and communicated to the Corporations management, including its principal executive officer and principal
financial officer, as appropriate to allow timely decisions regarding required disclosure.



There was no change in the Corporations internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended March 31,
2005, that has materially affected, or is reasonably likely to materially affect, the Corporations internal control over financial reporting.

Cautionary Statement



---



This Quarterly Report on Form 10-Q contains and incorporates by reference statements relating to future results of the Corporation that are
considered forward-looking statements. These statements, which may be expressed in a variety of ways, including the use of future or present tense language, relate to, among other things: expected cash contributions to funded defined
benefit pension plans; amounts of contingent and deferred consideration payable for acquisitions; the expected closing date of a transaction; additional costs or asset writedowns expected to be recorded in the second quarter of 2005 and thereafter;
the expected total after-tax loss on the sale of certain HR businesses to ACS; collectibility of securities; estimated amortization expense; long-term financial goals; quarters in which performance fees generally are highest; potential future
venture capital gains or losses, possible changes in the value of the portfolio and intentions as to future investments; expected second quarter 2005 net interest revenue; the effect of a new accounting standard related to share-based payments;
anticipated effective tax rate and the adequacy of tax accruals; the Corporations intention not to renew certain credit relationships; expected stock option expense in 2005 and 2006; liabilities for guarantees and indemnities; loss exposure
related to Three Rivers Funding Corporation (TRFC); credit exposure reserve appropriateness; the Corporations liquidity management and interest rate risk management objectives; contractual maturities of long-term debt; simulation of changes in
interest rates; the value-at-risk for trading activities and credit default swaps; and litigation results.



These forward-looking statements, and other forward-looking statements contained in other public disclosures of the Corporation which make reference to the cautionary factors contained in this report, are based on
assumptions that involve risks and uncertainties and that are subject to change based on various important factors (some of which are beyond the Corporations control). Actual results may differ materially from those expressed or implied as a
result of these risks and uncertainties, including, but not limited to: changes in political and economic conditions; equity and fixed-income and foreign exchange market fluctuations; changes in the mix of assets under management; the effects of the
adoption of new accounting standards; customers sensitivity to increases in oil prices and decreasing travel; corporate and personal customers bankruptcies; operational risk; inflation; levels of tax-free income; technological change;
success in the timely development of new products and services; competitive product and pricing pressures within Mellons markets; customer spending and savings habits; interest rate fluctuations; monetary fluctuations; currency rate
fluctuations; acquisitions and integrations of acquired businesses; changes in law; changes in fiscal, monetary, regulatory, trade and tax policies and laws; success in gaining regulatory approvals when required; the uncertainties inherent in the
litigation process; and the effects of recent and any further terrorist acts and the results of the war on terrorism; as well as other risks and uncertainties detailed elsewhere or incorporated by reference in this Quarterly Report on Form 10-Q and
in subsequent reports filed by the Corporation with the Securities and Exchange Commission pursuant to the Securities Exchange Act of 1934.



All statements speak only as of the date on which such statements are made, and the Corporation undertakes no obligation to update any statement to reflect events or
circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings.



Various
legal actions and proceedings are pending or are threatened against Mellon and our subsidiaries and certain former subsidiaries, some of which seek relief or damages in amounts that are substantial. These actions and proceedings arise in the
ordinary course of our businesses and operations and include suits relating to our servicing, investment, mutual fund, advisory, trust, custody, benefits consulting, shareholder services, cash management, lending, collections and other activities
and operations.



On March 22, 2005, the United States Attorney for the Western
District of Pennsylvania announced that six former employees of a subsidiary of Mellon had been indicted by a federal grand jury in Pittsburgh, Pennsylvania on a series of charges relating to the destruction in April 2001 of approximately 80,000
United States tax returns and payments. In related public comments, the United States Attorney indicated that the investigation is continuing. Mellon is cooperating fully in this investigation.



Because of the complex nature of some of these legal actions and proceedings, it may be a
number of years before such matters ultimately are resolved. After consultation with legal counsel, Mellons management believes that the aggregate liability, if any, resulting from such pending and threatened legal actions and proceedings will
not have a material adverse effect on our financial condition, results of operations and cash flows, although there could be a material effect on results of operations for a particular period.



Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.



|(a) | On Jan. 24, 2005, the Corporation issued 27,388 shares of common stock to Wachovia Bank, N.A., as Trustee of the Mellon Financial Corporation Deferred Share Award Trust No. 2. In
consideration for the issuance of the shares, Wachovia Bank, as Trustee, assumed the obligation of the Corporation under its Long-Term Profit Incentive Plan (2004) to deliver shares to individuals who received Deferred Share Awards under such Plan.
The issuance of shares was exempt from the registration requirements of the Securities Act of 1933 under section 4(2) as a transaction not involving any public offering.
