Exhibit 99.6

UNAUDITED PRO FORMA COMBINED CONSOLIDATED FINANCIAL INFORMATION

BANK OF NEW YORK AND MELLON FINANCIAL

The following Unaudited Pro Forma Combined Consolidated Balance Sheet combines the respective historical Consolidated Balance Sheets of The Bank of New York Company, Inc. (“Bank of New York”) and Mellon Financial Corporation (“Mellon Financial”) giving effect to the transaction as if it had been completed on March 31, 2007. The pro forma balance sheet assumes that the proposed transaction is accounted for as a purchase of Mellon Financial by Bank of New York and, accordingly, includes adjustments to record assets and liabilities of Mellon Financial at their estimated fair values, which are subject to further adjustment as additional information becomes available and additional analyses are performed. The related pro forma adjustments are described in the accompanying Notes to the Unaudited Pro Forma Combined Consolidated Financial Information.

The following Unaudited Pro Forma Combined Consolidated Statements of Income for the three months ended March 31, 2007 and year ended December 31, 2006 combine the respective historical Consolidated Statements of Income of Bank of New York and Mellon Financial giving effect to the proposed transaction as if it had become effective at January 1, 2006 as an acquisition by Bank of New York of Mellon Financial using the purchase method of accounting and giving effect to the related pro forma adjustments described in the accompanying notes to the Unaudited Pro Forma Combined Consolidated Financial Information.

We anticipate that the proposed transaction will provide The Bank of New York Mellon Corporation (“Newco”) with financial benefits that include reduced operating expenses. The pro forma information does not reflect the benefits of expected cost savings, opportunities to earn additional revenue, the impact of restructuring and transaction-related costs and, accordingly, does not attempt to predict or suggest future results. It also does not necessarily reflect what the historical results of Newco would have been had the proposed transaction been completed during these periods.

The unaudited pro forma combined consolidated financial information and notes are presented for illustrative purposes only. They include various estimates, which are subject to material change, and may not necessarily be indicative of the financial position or results of operations that would have occurred if the proposed transaction had been consummated as of the applicable date or which may be attained in the future. This pro forma financial information and notes should be read in conjunction with, and are qualified in their entirety by, the historical financial statements, including the notes thereto, of Bank of New York and Mellon Financial.

NOTES TO BANK OF NEW YORK AND MELLON FINANCIAL UNAUDITED PRO FORMA

COMBINED CONSOLIDATED FINANCIAL INFORMATION

Three Months Ended March 31, 2007 and Year Ended December 31, 2006

(Unaudited)

NOTE 1: PURCHASE BUSINESS COMBINATION

The transaction will be accounted for as an acquisition of Mellon Financial by Bank of New York using the purchase method of accounting and, accordingly, the assets and liabilities of Mellon Financial will be recorded at their respective fair values on the date the transaction is completed. The transaction will be effected by the issuance of Newco common stock, $0.01 par value, to Bank of New York shareholders and Mellon Financial shareholders. Each share of Bank of New York common stock will be exchanged for 0.9434 shares of Newco common stock, and each share of Mellon Financial common stock will be exchanged for one share of Newco common stock. The shares of Newco common stock issued to effect the transaction will be recorded at $39.86 per share. This amount was determined by averaging the closing price of Bank of New York common stock for the two trading days before the December 4, 2006 announcement of the transaction and the two trading days after the announcement of the transaction (which includes the day of the announcement), and dividing by the Bank of New York exchange ratio.

If a Bank of New York shareholder would otherwise be entitled to a fractional share of Newco common stock, cash will be issued instead of such fractional share of Newco common stock; the pro forma financial statements do not present an estimate of such cash, which is not expected to be material and will be funded by cash on hand.

The pro forma financial information includes estimated adjustments to record certain assets and liabilities of Mellon Financial at their respective fair values. Bank of New York and Mellon Financial are in the process of reviewing their accounting and reporting policies and, as a result of this review, it may be necessary to further reclassify the company’s financial statements to conform to those classifications that are determined by the combined company to be most appropriate (see Notes 8 and 9). While some reclassifications of prior periods have been included in the unaudited pro forma combined consolidated financial information, further reclassifications may be necessary upon the completion of this review. Material intercompany transactions have been eliminated from the unaudited pro forma combined consolidated financial information. The pro forma adjustments are subject to updates as additional information becomes available and as additional analyses are performed.

We expect to realize increased revenue and reduced operating expenses following the transaction which are not reflected in this pro forma financial information. No assurance can be given with respect to any level of such increased revenue and reduced operating expenses.

The final allocation of the purchase price will be determined after the transaction is completed and after thorough analyses to determine the fair values of Mellon Financial’s tangible and identifiable intangible assets and liabilities as of the date the transaction is completed. Any change in the fair value of the net assets of Mellon Financial will change the amount of the purchase price allocable to goodwill. Additionally, changes to Mellon Financial’s equity, including dividends and net income from April 1, 2007 through the date the transaction is completed, will also change the amount of goodwill recorded. The final adjustments may be materially different from the unaudited pro forma adjustments presented herein.

The goodwill recorded in connection with the transaction is not subject to amortization and none is deductible for tax purposes. The customer relationships, customer contract-based and core deposit intangibles will be amortized over their estimated economic lives based on the pattern of usage or consumption, if determinable. Any additional intangibles that are identified in connection with the transaction will be amortized in accordance with the provisions of SFAS No. 142, such that any with an indefinite life will not be subject to amortization, and any with a finite economic life will be amortized over the estimated useful life.

NOTES TO BANK OF NEW YORK AND MELLON FINANCIAL UNAUDITED PRO FORMA

COMBINED CONSOLIDATED FINANCIAL INFORMATION—(Continued)

Bank of New York and Mellon Financial are in the process of determining the appropriate methodology to allocate the goodwill, customer relationships, deposit base and other indefinite-lived intangibles to reportable segments and expect to finalize the analysis after the completion of the transaction.

NOTE 2: PRO FORMA FINANCIAL INFORMATION

The pro forma financial information for the transaction is included as of March 31, 2007 and for the three months ended March 31, 2007 and the year ended December 31, 2006. The pro forma adjustments in the pro forma financial statements reflect the right of each Mellon Financial shareholder to receive one share of Newco common stock for each share of Mellon Financial common stock held by such holder of record, based on the number of shares of Mellon Financial common stock that were outstanding on March 31, 2007. The unaudited pro forma financial information presented in the pro forma financial statements is not necessarily indicative of the results of operations in future periods or the future financial position of Newco.

The pro forma balance sheet adjustments reflect the issuance of 1.132 billion shares of Newco common stock with an aggregate par value of $11 million; an increase in paid-in capital of $15.2 billion as shown in Note 4; goodwill of $11.5 billion as shown in Note 3; and customer relationships and customer contract-based, core deposit and other indefinite-lived intangibles of $2.2 billion, $0.2 billion and $2.2 billion, respectively. Also included in the pro forma balance sheet adjustments is an increase in other liabilities, which includes estimated exit costs of $200 million, transaction costs of $45 million, other purchase accounting accruals and an increase of $1.7 billion in deferred income taxes.

When the transaction is completed, Bank of New York options will be exchanged for stock options in Newco and the option price per share will be adjusted for the 0.9434 exchange ratio.

Mellon Financial options will be exchanged for stock options in Newco and the option price per share will not be adjusted as the exchange ratio is one Mellon Financial share for one Newco share. All unvested Mellon Financial options granted prior to December 4, 2006 will be accelerated upon approval of the transaction, except for those for which waivers to acceleration were elected. Vested stock options issued by Newco in exchange for options held by employees and directors of Mellon Financial are considered part of the purchase price. Accordingly, the purchase price includes an estimated fair value of stock options of $344 million.

The fair value of Newco options that will be issued in exchange for Mellon Financial options was estimated by using the Black-Scholes option pricing model with market assumptions. Option pricing models require the use of highly subjective market assumptions, including expected stock price volatility, which if changed can materially affect fair value estimates. The more significant assumptions used in estimating the fair value include volatility of 22 percent, a dividend yield of 2.36 percent, an expected life of 50-75 percent of the remaining contractual terms and a risk-free interest rate for U.S. government bonds having a remaining life equal to the respective options’ expected lives.

The estimated exit cost liabilities assumed in the transaction consist principally of personnel-related costs, which include involuntary termination benefits for Mellon Financial employees to be severed in connection with the transaction, relocation costs for continuing Mellon Financial employees and costs to cancel contracts of Mellon Financial that will provide no future benefit to Newco. The estimated $200 million of exit cost liabilities include only those costs associated with Mellon Financial. Bank of New York estimated transaction costs of $45 million are included in goodwill.

During the three months ended March 31, 2007 and year ended December 31, 2006, Bank of New York and Mellon Financial acquired businesses or portions of businesses which are included herein only from the date of completion. Additional information, including selected pro forma information, related to acquisitions of Bank of New York may be found in Note 3, Acquisitions and Dispositions, to its consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2006.

The adjustment will be recognized over the respective remaining terms of the securities, which have a weighted average life of 3.7 years. The impact of the adjustment to pro forma interest income would have been less than $1 million for the year ended December 31, 2006 and the three months ended March 31, 2007.

(C) Adjustment to fair value Mellon Financial’s loan and lease portfolios. The adjustment to loans will be recognized over the respective remaining terms of the loans, which have a weighted average life of 1 year. The adjustment to lease finance assets in accordance with FASB Interpretation No. 21 ( Accounting for Leases in a Business Combination ) adjusts the lease finance assets carrying value to the present value of after-tax cash flows using current yields, as well as reverses the deferred tax liability that had previously been recorded on these lease finance assets by Mellon Financial. The adjustment to lease finance assets will be recognized over the respective remaining terms of the leases, which have a weighted average remaining life of 8 years. The estimated impact of the adjustment of loans and leases, assuming the transaction had been completed on January 1, 2006, would be an increase in interest income of $12 million, $13 million, $13 million, $14 million and $14 million for the years 2006 through 2010, respectively, and an increase of $3 million for the three months ended March 31, 2007. Based on current information regarding Mellon Financial’s loan portfolio, there are no material estimated differences between the contractual cash flows and the cash flows expected to be collected attributable to credit quality; accordingly, no such adjustment was applied. The pro forma adjustment reduces the reserve for losses on lease finance assets by $10 million to reflect the base credit reserve that would be recorded on the adjusted carrying value of the lease finance assets.

(D) Adjustment to fair value Mellon Financial premises and equipment. The impact of the adjustment to pro forma net occupancy expense and furniture and equipment expense would have been less than $1 million for the year ended December 31, 2006 and three months ended March 31, 2007.

(E) Adjustment to record goodwill and identifiable intangible assets resulting from the transaction based on estimated fair values as summarized in Note 3. The adjustments reflected in this prospectus supplement are based on current assumptions, valuations and estimated lives, which are subject to change. Material changes to these estimates are possible when the analysis is completed. For purposes of the pro forma adjustments shown here, management has estimated $4.6 billion of identifiable intangibles. The pro forma amortization expense of the estimated customer relationship, customer contract-based and core deposit intangible assets with estimable lives are estimated based on a pattern consistent with the assets’ identifiable cash flows, and the amortization expense of non-compete agreements is estimated using a straight-line method. The initial estimates of the fair values, amortization expense and lives are as follows:

			Pro Forma Amortization Expense
(in millions) Amortizing intangibles:	Estimated Fair Value		Year ended December 31, 2006		Three months ended March 31, 2007		Estimated Useful Lives or Contract Terms
Asset management customer relationships	$	1,670	$	220	$	55	10 years

COMBINED CONSOLIDATED FINANCIAL INFORMATION—(Continued)

(F) Adjustment of $663 million to fair value Mellon Financial’s investments in four strategic joint ventures, recorded in Other assets.

(G) Adjustment of $116 million to record in Other assets the favorable impact of operating leases compared to current market rates for the remainder of the lease terms. The estimated impact of the adjustment to current market rates, assuming the transaction had been completed on January 1, 2006, would be an increase in net occupancy expense of approximately $17 million in 2006, $18 million for each of the years from 2007-2010 and $5 million for the three months ended March 31, 2007.

(H) Adjustment to fair value Mellon Financial’s term deposit liabilities based on current interest rates for similar instruments. The adjustment will be recognized over the weighted average estimated remaining term of the related deposit liabilities of 0.3 years. This adjustment increases pro forma interest expense by $1 million for the year ended December 31, 2006 and less than $1 million for the three months ended March 31, 2007.

(I) Adjustment to fair value Mellon Financial’s notes, debentures and junior subordinated debentures, all of which are included as Long-term debt in the Combined Consolidated Balance Sheet. The adjustment will be recognized over the respective remaining lives of the instruments, which have a weighted average life of 9.8 years. The estimated impact of the $95 million pro forma adjustment of long-term debt, assuming the transaction had been completed on January 1, 2006, would be decreases in interest expense of $18 million, $13 million, $12 million, $7 million and $5 million for the years 2006 through 2010, respectively, and a decrease of $3 million for the three months ended March 31, 2007. These were estimated using a straight-line basis over the respective remaining maturities of the long-term debt instruments. These pro forma adjustments do not reflect any impact from the effect of the debt to be issued under this prospectus supplement or the use of the proceeds thereof.

(J) Adjustment to reverse $89 million of accrued liabilities related to Mellon Financial’s operating leases with either free rent periods or “step-up” annual lease payments that were recorded under SFAS No. 13 (Accounting for Leases). Under SFAS No. 13, the expense related to operating leases with lease payments increasing subsequent to the date of the completion of the transaction will be recorded on a straight-line basis over the respective leases’ remaining terms. The accrual increased $20 million from January 1, 2006 to March 31, 2007; accordingly, no pro forma adjustment to reduce rental expense is presumed to have occurred for the three months ended March 31, 2007 or the year ended December 31, 2006.

(K) Adjustment to increase the fair value of Mellon Financial’s pension liability by $9 million for the effect of a pre-existing change of control provision for certain employees in Mellon Financial’s pension plan. The $56 million decrease to pro forma staff expense for the year ended December 31, 2006 includes (1) a decrease of $58 million for the amortization of prior service cost and recognized net actuarial loss on pensions and amortization of transition obligation on postretirement benefits other than pensions recognized by Mellon Financial in 2006 and (2) a pro forma increase of $2 million for the service and interest components of expense that would have been recorded in 2006 for the effect of the pre-existing change of control provision for certain employees. The pro forma adjustments for the three months ended March 31, 2007 was estimated at approximately one fourth of the annual estimate. Additional analyses and actuarial valuations will be performed by the combined company’s actuaries after the transaction, and these estimates may be subject to material change. The adjustments reflected herein do not reflect any effects from restructuring the combined company workforce.

(L) Adjustment to record the tax effects of the pro forma adjustments in the Balance Sheet, except the adjustment to lease finance assets (as described in Note C above), using a combined federal, state and foreign tax rate of 38 percent.

(M) Adjustment to record as liabilities the estimated exit costs related to Mellon Financial and transaction costs incurred by Bank of New York, both of which are included in the estimated $1.3 billion of merger and

NOTES TO BANK OF NEW YORK AND MELLON FINANCIAL UNAUDITED PRO FORMA

COMBINED CONSOLIDATED FINANCIAL INFORMATION—(Continued)

integration costs, discussed further in Note 6. The estimated exit costs will include severance (including the effect of change in control provisions in Mellon Financial’s displacement program) and relocation costs of continuing Mellon Financial employees, costs to cancel contracts of Mellon Financial that will provide no future benefit to Newco, and other costs. Also included in the pro forma adjustment is $45 million for Bank of New York’s investment banking, attorney and independent accountant fees, and other transaction-related costs.

(N) Adjustment to record the fair value of Mellon Financial’s employees’ stock options and directors’ stock options and deferred share units. The fair value of Mellon Financial’s options to be exchanged for Newco options was estimated using a Black-Scholes pricing model. Option pricing models require the use of highly subjective assumptions including expected stock price and volatility that, when changed, can materially affect fair value estimates. The more significant assumptions used in estimating the fair value include volatility of 22 percent, a dividend yield of 2.36 percent, an expected life of 50 to 75 percent of the remaining contractual terms and a risk-free interest rate for U.S. government bonds having a remaining life equal to the respective options’ expected lives.

(O) Adjustment to increase staff expense resulting from the revaluation of Mellon Financial’s unvested awards, primarily for those individuals who elected to waive acceleration of vesting. The original valuations of these awards were determined by Mellon Financial at the original grant dates. Upon completion of the transaction, these awards will be revalued using current market assumptions. The unrecognized compensation expense for these stock-based awards and those issued in the three months ended March 31, 2007 was $114 million at March 31, 2007. Annual compensation expense related to these awards is expected to be greater than historic compensation expense due to the increase in the value of the awards upon remeasurement. For unvested stock options, the average remaining vesting period is 4.5 years and the average remaining contractual life is 9.7 years. For unvested restricted stock awards, the average remaining vesting period is 2.4 years. Pursuant to FAS 123(R), unvested awards are not considered a component of purchase price and are solely recognized in compensation expense in future periods.

(P) Adjustment to eliminate intercompany assets and liabilities. These include: (i) $11 million of Mellon Financial junior subordinated debentures, included in long-term debt, which were included in securities available for sale by Bank of New York, (ii) $3 million of Mellon Financial trading liability recorded as a trading asset receivable by Bank of New York, (iii) $3 million of Mellon Financial cash and due from banks and held in deposits by Bank of New York, and (iv) $6 million of miscellaneous receivables/payables in other assets and other liabilities. The amount of interest earned on the junior subordinated debentures for the period held in 2006 and 2007 as an investment was less than $1 million, and the revenue and expense related to the other items described above was de minimis.

(Q) Weighted average shares of Newco were calculated using the historical weighted average shares outstanding for the year ended December 31, 2006 of Bank of New York shares adjusted using the exchange ratio of 0.9434 and Mellon Financial shares using the 1:1 exchange ratio. Earnings per share data have been computed based on the combined historical income from continuing operations of Bank of New York and Mellon Financial and the impact of pro forma purchase accounting adjustments.

(R) Adjustment to eliminate merger and integration expenses recorded by Mellon Financial and Bank of New York related to the transaction.

(S) Adjustment to reverse amortization expense of intangible assets recorded in Mellon Financial’s historical financial statements.

(T) Adjustment to eliminate intercompany revenue and expenses for Clearing services and Asset servicing paid by Mellon Financial to Bank of New York.

NOTES TO BANK OF NEW YORK AND MELLON FINANCIAL UNAUDITED PRO FORMA

COMBINED CONSOLIDATED FINANCIAL INFORMATION—(Continued)

(U) The adjustment included in the pro forma tax provision related to lease finance assets includes the taxes that would be recorded for these assets based on the new carrying value as described in Note C above, rather than the 38% statutory provision for combined federal, state and foreign taxes used for all other pro forma adjustments.

NOTE 6: MERGER AND INTEGRATION EXPENSE

In connection with the transaction, Bank of New York and Mellon Financial have begun to develop their preliminary plans for post-merger integration of their operations. Over the next several months, the specific details of these plans will be refined. Bank of New York and Mellon Financial are currently in the process of assessing the two companies’ personnel, benefit plans, premises, equipment, computer systems and service contracts to determine where they may take advantage of redundancies or where it will be beneficial or necessary to convert to one system.

Certain decisions arising from these assessments may involve involuntary termination of employees, vacating leased premises, canceling contracts with certain service providers and selling or otherwise disposing of certain premises or equipment. To the extent these decisions relate to Mellon Financial employees, assets or contracts, the costs associated with such decisions as permitted will be recorded as purchase accounting adjustments, which have the effect of increasing the amount of the purchase price allocable to goodwill. It is expected that all such costs will be identified and recorded within one year of completion of the transaction and all such actions required to effect these decisions would be taken within one year after finalization of these plans. The Unaudited Pro Forma Combined Consolidated Balance Sheet includes a preliminary estimate of such liabilities of $200 million. See Notes 2, 3 and 5 for additional disclosures.

To the extent these decisions relate to Bank of New York employees, assets or contracts, these exit and disposal costs would be recorded in accordance with FASB Statement Nos. 146 and 112 in the results of operations of Newco in the period incurred.

Newco also expects to incur transaction-related expenses in the process of combining the operations of the two companies. These transaction-related expenses may include system conversion costs, employee retention arrangements and costs of incremental communications to customers and others. It is expected that the exit and disposal costs along with the transaction-related costs will be incurred over a three-year period after completion of the transaction. These expenses are not included in the Unaudited Pro Forma Combined Consolidated Income Statement because these costs will be recorded in the combined results of operations as they are incurred after completion of the transaction and are not indicative of what the historical results of Newco would have been had Bank of New York and Mellon Financial actually been combined during the periods presented.

Preliminarily, we estimate that the total of Mellon Financial’s exit costs, Bank of New York’s transaction and restructuring costs and Newco’s integration costs will be approximately $1.3 billion.

NOTE 7: DIVIDENDS

Following the completion of the transaction, it is anticipated that Newco will initially pay a quarterly cash dividend of $0.235 per share. Prior to the completion of the transaction, Bank of New York intends to maintain its $0.22 per share regular quarterly dividend. Prior to the completion of the transaction, Mellon Financial intends to maintain regular quarterly dividends at a rate not to exceed $0.22 per share.
