PNC 2006 DILUTED EPS OF $8.73 SETS ALL-TIME RECORD Adjusted diluted EPS of $5.06 excludes net effects of BlackRock transaction and balance sheet repositioning Total assets exceed $100 billion for first time

     PITTSBURGH, Jan. 23, 2007 – The PNC Financial Services Group, Inc. (NYSE: PNC) today reported record 2006 net income of $2.6 billion, or $8.73 per diluted share, compared with 2005 net income of $1.3 billion, or $4.55 per diluted share.

     PNC earned adjusted net income of $1.5 billion, or $5.06 per diluted share, for the year. Adjusted net income for 2006 excluded, after-tax, a $1.3 billion gain on the BlackRock/Merrill Lynch Investment Managers (MLIM) transaction, a $127 million loss on the repositioning of PNC’s securities portfolio, $47 million in BlackRock/MLIM transaction integration costs and a $31 million loss on the repositioning of PNC’s mortgage loan portfolio, as noted in the adjustments on page 13 of this release.

     Net income for the fourth quarter of 2006 was $376 million, or $1.27 per diluted share. Excluding BlackRock/MLIM transaction integration costs of $8 million after-tax, adjusted net income for the fourth quarter of 2006 was $384 million, or $1.30 per diluted share. Net income was $355 million, or $1.20 per diluted share, in the fourth quarter of 2005.

     “PNC delivered extraordinary value to its shareholders in 2006,” said PNC Chairman and Chief Executive Officer James E. Rohr. “Total return was among the best in the industry. We grew customers, revenue, and average loans and deposits compared with 2005. At the same time, we accomplished key strategic initiatives. The completion of the BlackRock/MLIM transaction, the announcement of our planned Mercantile acquisition and our continuing success in risk management position us well for the years ahead.”

HIGHLIGHTS

• Total PNC assets exceeded $100 billion for the first time. We believe this further confirms PNC’s position among an elite group of U.S. banks with the scale to compete in a consolidating industry.
• Average loans of $49.0 billion for the fourth quarter of 2006 increased $210 million compared with the fourth quarter 2005. Average loans increased $2.1 billion, or 4 percent, compared with the prior year fourth quarter excluding the effect of a $1.9 billion decrease in residential mortgage loans related to PNC’s third quarter balance sheet repositioning. The increase was largely due to growth in commercial and commercial real estate loans.
• Average deposits for the fourth quarter increased $4.2 billion, or 7 percent, compared with the same quarter in the prior year, primarily as a result of an increase in interest-bearing deposits as customers continued to shift deposits to higher-return accounts. Average noninterest-bearing deposits increased $770 million, or 5 percent, compared with the fourth quarter of 2005.
• Asset quality remained very strong. Nonperforming loans decreased $20 million, or 12 percent, compared with September 30, 2006, to .29 percent of total loans.
• PNC’s integration of Mercantile Bankshares Corporation is progressing on track and has achieved several important objectives, including identifying leadership personnel for key positions within the Mercantile service

                 territory. PNC’s priority for the integration is the retention of customers and customer-facing staff. The transaction is expected to close
                 in March of 2007.

     Return on average common shareholders’ equity for the year was 27.97 percent, or 16.24 percent, as adjusted. Return on average common shareholders’ equity for 2005 was 16.58 percent. For the fourth quarter of 2006, return on average common shareholders’ equity was 13.82 percent, or 14.10 percent, as adjusted. The return on average common shareholders’ equity was 16.91 percent for the fourth quarter of 2005. The decline of the return from the fourth quarter of 2005 to the fourth quarter of 2006 was due to the significant increase in equity resulting from the BlackRock/MLIM transaction.

     As described on page 9 of this news release, the Consolidated Financial Highlights accompanying this news release include several new and reformatted schedules to reconcile the reported and adjusted results, including adjusted results referred to in this news release, and to provide information illustrating the impact of the equity method of accounting for BlackRock.

BUSINESS SEGMENT RESULTS

Retail Banking

Retail Banking earned $184 million for the quarter, compared with $195 million for the year-ago quarter and $206 million for the third quarter of 2006. The decreases when compared with the prior year fourth quarter and the prior quarter were largely the result of an increase in the provision for credit losses due to small business commercial loan growth. Revenue growth, primarily driven by fee income, was substantially offset by higher expenses associated with increased fee income and business growth initiatives. These initiatives included continued expansion of the Private Client Group and branch network, the launch of a refined set of checking products, a new PNC branded credit card, and an increase to majority ownership of the merchant services business. 
     Full year 2006 earnings increased $83 million, to $765 million, a 12 percent increase in earnings. Compared with the full year 2005, revenue increased 9 percent, while noninterest expense increased 6 percent, creating positive operating leverage.

Retail Banking highlights:

• Checking relationships grew by a net 20,000 compared with a year ago and declined slightly since September 30, 2006, as PNC focused on consolidating low-activity, low-balance accounts and sought higher quality relationships.
• Small business lending continues to be an area of growth; loan balances grew 13 percent over the prior year quarter and 2 percent over the linked quarter.
• Average deposit balances increased $1.7 billion, or 4 percent, compared with the prior year fourth quarter and $596 million, or 1 percent, from the prior quarter. In the current rate environment, certificates of deposit have been the major growth product over the periods of comparison.
• Assets under management were $54 billion at December 31, 2006, an increase of $5 billion, or 10 percent, compared with December 31, 2005 and an increase of $2 billion, or 4 percent, compared with September 30, 2006. Customer assets in brokerage accounts totaled $46 billion at December 31, 2006 compared with $42 billion at December 31, 2005 and $44 billion at September 30, 2006.
• Noninterest income for the fourth quarter of 2006 increased $42 million, or 12 percent, compared with the prior year quarter and $16 million, or 4 percent, compared with the third quarter of 2006. The growth in fee income from the prior year fourth quarter was driven by higher gains from asset sales, higher revenue from our brokerage and asset management businesses given the favorable equity markets, and new business initiatives.
• Noninterest expense for the fourth quarter of 2006 increased $37 million, or 9 percent, compared with the prior year fourth quarter and $15 million, or 3 percent, compared with the third quarter of 2006. The growth in expenses for both comparisons was primarily a result of expenses directly associated with fee income related businesses and a number of growth initiatives in the business.
• Asset quality in the Retail Banking segment continues to be very strong.

Corporate & Institutional Banking

Corporate & Institutional Banking earned $463 million in 2006, compared with $480 million in 2005. The 2005 results included the after-tax benefit of a large loan recovery of $34 million recognized in the second quarter. Earnings grew 7 percent year over year excluding the provision for credit losses of $27 million after tax in 2006 and net recovery of credit losses of $20 million after tax in 2005.

     Corporate & Institutional Banking earned $129 million in the fourth quarter, compared with $108 million in the fourth quarter of the prior year and $113 million in the third quarter of 2006. The increase when compared with the fourth quarter of 2005 was largely the result of a decrease in provision for credit losses and increases in corporate service fees and net interest income, partly offset by an increase in noninterest expense. The earnings increase compared with the prior quarter was primarily attributable to growth in fee and trading revenue, partly offset by an increase in noninterest expense.

Corporate & Institutional Banking highlights:

• Noninterest income increased 17 percent compared with the prior year quarter and the third quarter of 2006. The growth compared with the prior year quarter was the result of higher revenue from capital markets, including the impact of Harris Williams, and higher treasury management revenue. The increase compared with the prior quarter largely was due to growth in capital markets revenues, affordable housing partnership distribution income and net gains on commercial mortgage loan sales.
• Noninterest expense increased $22 million, or 12 percent, compared with the fourth quarter of 2005, largely due to an increase in expenses associated with higher corporate services fee revenue. Fourth quarter 2006 expenses increased $17 million, or 9 percent, compared with the prior quarter, due to the growth in commercial real estate activities.
• Average loan balances increased $1.2 billion from the prior year fourth quarter. Average loans in the prior year included $430 million in average loans from Market Street, which was deconsolidated in October 2005.
  Excluding the impact of the Market Street loans, average loan balances increased approximately $1.7 billion, or 9percent, driven by demand for corporate, commercial real estate and asset-based lending loans.
• Average deposit balances for the quarter increased $1.6 billion, or 16 percent, compared with the fourth quarter of 2005. On a linked quarter basis, average deposits increased $1.3 billion or 12 percent, driving a 4 percent growth in net interest income. The increases compared with the prior year quarter and prior quarter were due to growth in the commercial mortgage servicing portfolio of Midland and treasury management services.
• The commercial mortgage servicing portfolio was $200 billion at December 31, 2006, an increase of 47 percent from December 31, 2005.
• Asset quality continued to be strong with nonperforming assets declining compared with the linked quarter.

BlackRock

PNC’s BlackRock segment earned $50 million in the fourth quarter of 2006, compared with $48 million in the fourth quarter of 2005 and $42 million in the prior quarter. These amounts include the impact of PNC’s taxes associated with our share of BlackRock’s income, previously recorded in the Other segment. 

     For PNC business segment reporting presentation, PNC reflects its portion of integration costs incurred by BlackRock for the MLIM transaction in “Other” rather than in earnings from its BlackRock investment.

     Prior to the September 29, 2006 closing of the MLIM transaction, PNC owned approximately 69 percent of BlackRock. For the periods prior to the BlackRock/MLIM transaction closing, PNC’s earnings from its investment in BlackRock as presented above have been reduced by minority interest in the income of BlackRock. 

     Upon closing of the MLIM acquisition, PNC owned approximately 34 percent of BlackRock. In accordance with generally accepted accounting principles, PNC deconsolidated BlackRock and, beginning with the fourth quarter of 2006, accounted for BlackRock’s earnings contribution using the equity method, with BlackRock’s contribution to PNC’s earnings reported in the asset management line item of PNC’s consolidated income statement.

PFPC

PFPC earned $124 million in 2006, compared with $104 million in 2005. The increase resulted from the benefit of a deferred tax reversal of $14 million in the third quarter, increased servicing revenue and disciplined expense control. 

     The business earned $31 million for the quarter, compared with $29 million in the year-earlier period and $40 million in the linked quarter. The earnings decrease from the third quarter of 2006 reflected the tax benefit in the earlier period. 

     PFPC provided accounting/administration services for $837 billion of net fund assets and provided custody services for $427 billion of fund assets as of December 31, 2006, compared with $835 billion and $476 billion, respectively, on December 31, 2005 and $774 billion and $399 billion, respectively, at September 30, 2006. Total fund assets serviced by PFPC were $2.2 trillion at December 31, 2006, which represented an increase over the asset servicing levels of $1.9 trillion at December 31, 2005 and $2.0 trillion at September 30, 2006.

Other

The “Other” category includes the gains (losses) related to BlackRock, BlackRock/MLIM transaction integration costs, One PNC implementation costs, asset and liability management activities, related net securities gains or losses, certain trading activities, equity management activities, differences between business segment performance reporting and financial statement (GAAP) reporting, corporate overhead, and intercompany eliminations. 

     PNC recorded a net loss of $18 million in Other for the quarter, including $8 million after-tax in BlackRock/MLIM transaction integration costs, compared with a net loss of $25 million in the fourth quarter of 2005 and a net gain of $1.1 billion in the third quarter of 2006. The third quarter of 2006 included a $1.3 billion after-tax gain on the BlackRock/MLIM transaction, partly offset by the $127 million after-tax securities portfolio rebalancing loss, $31 million after-tax BlackRock/MLIM transaction integration costs and a $31 million after-tax loss on the mortgage loan portfolio repositioning.

CONSOLIDATED REVENUE REVIEW

Taxable-equivalent net interest income totaled $571 million for the quarter, an increase of $3 million compared with the year-earlier period and a decrease of $3 million compared with the third quarter of 2006. The net interest margin in the fourth quarter of 2006 was 2.88 percent, compared with 2.96 percent in the year-earlier period and 2.89 percent in the third quarter of 2006. The increase in net interest income over the prior year quarter was largely the result of increased interest income from loans and securities, partly offset by the higher cost of deposits and borrowings. The decrease compared with the prior quarter was due to the deconsolidation of BlackRock. The Consolidated Financial Highlights accompanying this news release include a reconciliation of taxable-equivalent net interest income to net interest income as reported under GAAP. 

     Noninterest income totaled $969 million, or $979 million as adjusted for BlackRock/MLIM transaction integration costs, for the fourth quarter of 2006 compared with $1.2 billion, or $837 million as adjusted, for the same quarter in the prior year, and $2.9 billion, or $832 million as adjusted, in the third quarter of 2006. Noninterest income as adjusted reflects the impact of certain significant 2006 items (the BlackRock/MLIM transaction and balance sheet repositionings) and BlackRock equity method of accounting as noted in the Consolidated Financial Highlights section of this release. 

     The increase in adjusted noninterest income compared with the fourth quarter of 2005 and third quarter 2006 adjusted results was due primarily to an increase in fund servicing, asset management, and corporate and consumer service revenues. Customer-driven fee revenue increased compared with the year earlier period, including a 24 percent increase in corporate services and a 16 percent increase in consumer services. 

     Asset management revenue as adjusted increased 24 percent compared with the fourth quarter of 2005, due to an increased contribution from BlackRock and higher assets under management in Retail Banking’s wealth management business. Fund servicing revenue increased largely as a result of growth in distribution/out-of-pocket revenues at PFPC due to the BlackRock/MLIM merger. These revenues and the related expenses are recorded on a gross basis with no operating margin.

CONSOLIDATED EXPENSE REVIEW

Noninterest expense for the three months ended December 31, 2006 was $969 million, compared with the prior year quarter noninterest expense of $1.1 billion, or $870 million as adjusted, and noninterest expense of $1.2 billion, or $872 million as adjusted, for the third quarter of 2006. Also excluding PFPC’s distribution/out-of-pocket expenses noted above, which were $64 million, $32 million and $35 million in the fourth quarter 2006, fourth quarter 2005 and third quarter 2006, respectively, the increases compared with both adjusted quarters would have been approximately $67 million, or 8 percent. The increase was equally driven by increased costs associated with higher staff incentive compensation, including a $16 million one-time payment to non-executive employees, and other expense growth, including the call of trust preferred securities. Noninterest expense as adjusted reflects adjustments related to the impact of certain significant 2006 items and BlackRock equity method of accounting, as listed in the Consolidated Financial Highlights section of this release.

CONSOLIDATED BALANCE SHEET REVIEW

Total assets were $101.8 billion at December 31, 2006, compared with $92.0 billion at December 31, 2005, and $98.4 billion at September 30, 2006. The increase compared with year-end 2005 reflected a $4.0 billion increase in equity investments primarily due to the impact of the BlackRock/MLIM transaction on PNC and growth in securities and loans. The increase compared with the third quarter of 2006 was largely due to an increase in loans and securities, reflecting the third quarter balance sheet repositioning. 

     Average loans of $49.0 billion for the quarter increased $210 million over the year-earlier period and decreased $1.3 billion, or 3 percent, compared with the linked period. Average loans increased $2.1 billion, or 4 percent, compared with the prior year fourth quarter excluding the $1.9 billion decrease in residential mortgage loans related to PNC’s balance sheet repositioning. The increase in average loans compared with the fourth quarter of 2005 was primarily a result of increased

commercial and commercial real estate loans. The decrease from the third quarter of 2006 was a result of the lower residential mortgages after the balance sheet repositioning, partly offset by growth in commercial real estate and consumer loans. 

     Average securities for the fourth quarter of 2006 were $21.2 billion, an increase of $413 million, or 2 percent, compared with the fourth quarter of 2005, and average securities decreased $469 million, or 2 percent, compared with the linked quarter. The increase in securities compared with the prior year quarter was primarily the result of an increase in mortgage- and asset-backed securities, offset by a decline in U.S. Treasury and government agency securities. This change in mix resulted in part from the third quarter 2006 balance sheet repositioning. The decrease in securities compared with the third quarter of 2006 was primarily the result of the balance sheet repositioning, somewhat offset by growth in mortgage- and asset-backed securities. 

     Average deposits of $65.0 billion increased $4.2 billion, or 7 percent, compared with the same quarter in the prior year, and increased $393 million, or 1 percent, compared with the linked quarter. Average deposits grew from the prior year quarter primarily as a result of an increase in interest-bearing deposits as customers continued to shift deposits to higher-return accounts. Average deposits compared with the prior quarter increased as a result of growth in money market and retail certificates of deposit, partly offset by a decline in Eurodollar deposits. Average demand and other noninterest-bearing deposits increased $770 million, or 5 percent, compared with the prior year quarter and increased $278 million, or 2 percent, versus the linked quarter, largely as a result of deposits attributed to the commercial mortgage servicing portfolio at Midland. 

     PNC’s Tier 1 risk-based capital ratio was an estimated 10.4 percent at December 31, 2006, compared with 8.3 percent at December 31, 2005 and 10.4 percent at September 30, 2006. 

     The company repurchased 1.3 million common shares during the fourth quarter under its current common stock repurchase program. The board has authorized a repurchase of up to 20 million shares of common stock, of which approximately 14.5 million remained at the end of the fourth quarter. Following the vote of the Mercantile shareholders regarding the acquisition by PNC, management expects to resume its share repurchase program. 

     Under the terms of its definitive agreement to acquire Mercantile Bankshares Corporation, which is subject to customary closing conditions, including regulatory and Mercantile shareholder approvals, PNC plans to issue 52.5 million shares of common stock and pay Mercantile shareholders and option holders $2.13 billion in cash upon close of the transaction, expected in March of 2007.

ASSET QUALITY REVIEW

Overall asset quality remained very strong as the company continued to focus on lending that meets prudent risk-reward parameters. The provision for credit losses for the fourth quarter of 2006 was $42 million, compared with $24 million in the fourth quarter of 2005 and $16 million in the third quarter of 2006. The increase in the provision compared with the linked quarter was primarily due to growth in the loan portfolio. 

     Net charge-offs for the fourth quarter of 2006 were $45 million, or .36 percent of average loans, compared with net charge-offs of $41 million, or .33 percent, for the fourth quarter of 2005 and net charge-offs of $47 million, or .37 percent, for the linked quarter. 

     Nonperforming assets at December 31, 2006 declined 21 percent compared with the balances at December 31, 2005 and 10 percent compared with September 30, 2006.

CONSOLIDATED FINANCIAL HIGHLIGHTS

The Consolidated Financial Highlights accompanying this news release include: (1) adjusted results for 2006 and 2005, the four quarters of 2006 and the fourth quarter of 2005 illustrating the impact of certain 2006 items, including the gain on the BlackRock/MLIM transaction net of expense, securities portfolio and mortgage loan portfolio rebalancing losses and BlackRock/MLIM transaction integration costs, due to the magnitude of the aggregate of those items for those periods and the impact of the deconsolidation and application of the equity method of accounting for BlackRock, and (2) a reconciliation of these adjusted amounts to net income, certain components of net income, diluted earnings per share and selected ratios as reported under generally accepted accounting principles (GAAP), and to GAAP condensed, consolidated income statements. We have provided these adjusted amounts and reconciliations so that investors, analysts, regulators and others will be better able to evaluate the impact of certain significant items on our GAAP results for these periods. The absence of other adjusted amounts for periods discussed in this news release is not intended to imply that there could not have been other similar types of adjustments for these periods, but any such adjustments would not have been similar in magnitude to the amount of the adjustments shown.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

We make statements in this news release and in the conference call regarding this news release, and we may from time to time make other statements, regarding our outlook or expectations for earnings, revenues, expenses and/or other matters regarding or affecting PNC that are forward-looking statements within the meaning of the Private Securities Litigation Reform Act. Forward-looking statements are typically identified by words such as “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project” and other similar words and expressions.

Forward-looking statements are subject to numerous assumptions, risks and uncertainties, which change over time. Forward-looking statements speak only as of the date they are made. We do not assume any duty and do not undertake to update our forward-looking statements. Because forward-looking statements are subject to assumptions and uncertainties, actual results or future events could differ, possibly materially, from those that we anticipated in our forward-looking statements, and future results could differ materially from our historical performance.

Our forward-looking statements are subject to the following principal risks and uncertainties. We provide greater detail regarding some of these factors in our Form 10-K for the year ended December 31, 2005 and in our 2006 Form 10-Qs, including in the Risk Factors and Risk Management sections of those reports. Our forward-looking statements may also be subject to other risks and uncertainties, including those that we may discuss elsewhere in this news release or in our filings with the SEC, accessible on the SEC’s website at www.sec.gov and on or through our corporate website at www.pnc.com under “About PNC – Investor Relations – Financial Information.”

• Our business and operating results are affected by business and economic conditions generally or specifically in the principal markets in which we do business. We are affected by changes in our customers’ financial performance, as well as changes in customer preferences and behavior, including as a result of changing economic conditions.
• The value of our assets and liabilities as well as our overall financial performance are affected by changes in interest rates or in valuations in the debt and equity markets. Actions by the Federal Reserve and other government agencies, including those that impact money supply and market interest rates, can affect our activities and financial results.
• Competition can have an impact on customer acquisition, growth and retention, as well as on our credit spreads and product pricing, which can affect market share, deposits and revenues.
• Our ability to implement our One PNC initiative, as well as other business initiatives and strategies we may pursue, could affect our financial performance over the next several years.
• Our ability to grow successfully through acquisitions is impacted by a number of risks and uncertainties related both to the acquisition transactions themselves and to the integration of the acquired businesses into PNC after closing. These uncertainties are present in transactions such as our pending acquisition of Mercantile Bankshares Corporation.
• Legal and regulatory developments could have an impact on our ability to operate our businesses or our financial condition or results of operations or our competitive position or reputation. Reputational impacts, in turn, could affect matters such as business generation and retention, our ability to attract and retain management, liquidity and funding. These legal and regulatory developments could include: (a) the unfavorable resolution of legal proceedings or regulatory and other governmental inquiries; (b) increased litigation risk from recent regulatory

and other governmental developments; (c) the results of the regulatory examination process, our failure to satisfythe requirements of agreements with governmental agencies, and regulators’ future use of supervisory andenforcement tools; (d) legislative and regulatory reforms, including changes to laws and regulations involvingtax, pension, and the protection of confidential customer information; and (e) changes in accounting policies andprinciples.
• Our business and operating results are affected by our ability to identify and effectively manage risks inherent in our businesses, including, where appropriate, through the effective use of third-party insurance and capital management techniques.
• Our ability to anticipate and respond to technological changes can have an impact on our ability to respond to customer needs and to meet competitive demands.
• The adequacy of our intellectual property protection, and the extent of any costs associated with obtaining rights in intellectual property claimed by others, can impact our business and operating results.
• Our business and operating results can be affected by widespread natural disasters, terrorist activities or international hostilities, either as a result of the impact on the economy and financial and capital markets generally or on us or on our customers, suppliers or other counterparties specifically.
• Also, risks and uncertainties that could affect the results anticipated in forward-looking statements or from historical performance relating to our interest in BlackRock, Inc. are discussed in more detail in BlackRock’s 2005 Form 10-K, including in the Risk Factors section, and in BlackRock’s other filings with the SEC, accessible on the SEC’s website and on or through BlackRock’s website at www.blackrock.com.

In addition, our pending acquisition of Mercantile Bankshares presents us with a number of risks and uncertainties related both to the acquisition transaction itself and to the integration of the acquired businesses into PNC after closing. These risks and uncertainties include the following:

• Completion of the transaction is dependent on, among other things, receipt of regulatory and Mercantile shareholder approvals, the timing of which cannot be predicted with precision at this point and which may not be received at all. The impact of the completion of the transaction on PNC’s financial statements will be affected by the timing of the transaction.
• The transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events.
• The integration of Mercantile’s business and operations with those of PNC, which will include conversion of Mercantile’s different systems and procedures, may take longer than anticipated, may be more costly than anticipated, and may have unanticipated adverse results relating to Mercantile’s or PNC’s existing businesses.
• The anticipated benefits, including anticipated strategic gains and anticipated cost savings and other synergies of the transaction, may be significantly harder or take longer to be realized than anticipated or may not be achieved in their entirety, including as a result of unexpected factors or events, and attrition in key client, partner and other relationships relating to the transaction may be greater than expected.
• The anticipated benefits to PNC are dependent in part on Mercantile’s business performance in the future, and there can be no assurance as to actual future results, which could be impacted by various factors, including the risks and uncertainties generally related to PNC’s and Mercantile’s performance (with respect to Mercantile, see Mercantile’s SEC reports, accessible on the SEC’s website) or due to factors related to the acquisition of Mercantile and the process of integrating it into PNC.

In addition to the pending Mercantile Bankshares transaction, we grow our business from time to time by acquiring other financial services companies. Acquisitions in general present us with risks other than those presented by the nature of the business acquired. In particular, acquisitions may be substantially more expensive to complete (including as a result of costs incurred in connection with the integration of the acquired company) and the anticipated benefits (including anticipated cost savings and strategic gains) may be significantly harder or take longer to achieve than expected. In some cases, acquisitions involve our entry into new businesses or new geographic or other markets, and these situations also present risks resulting from our inexperience in these new areas. As a regulated financial institution, our pursuit of attractive acquisition opportunities could be negatively impacted due to regulatory delays or other regulatory issues. Regulatory and/or legal issues related to the pre-acquisition operations of an acquired business may cause reputational harm to PNC following the acquisition and integration of the acquired business into ours and may result in additional future costs and expenses arising as a result of those issues.

Certain prior period amounts included in these Consolidated Financial Highlights have been reclassified to conform with the current period presentation.

The tables above represent reconciliations of certain GAAP disclosures to adjusted amounts for the periods presented. We have provided these adjusted amounts and reconciliations so that shareholders, investor analysts, regulators and others will be better able to evaluate the impact of certain significant items on our GAAP results for these periods. This information supplements our results as reported in accordance with GAAP and should not be viewed in isolation from, or as a substitute for, our GAAP results. The absence of other adjustments is not intended to imply that there could not have been other similar types of adjustments, but any such adjustments would not have been similar in magnitude to the amount of the adjustments shown. Our third quarter 2006 Form 10-Q includes additional information regarding our BlackRock/MLIM transaction accounting, securities portfolio rebalancing, and mortgage loan portfolio repositioning.

RECONCILIATION OF NET INTEREST INCOME ON A GAAP BASIS TO TAXABLE-EQUIVALENT NET INTEREST INCOME
The interest income earned on certain assets is completely or partially exempt from federal income tax. As such, these tax-exempt instruments typically yield lower returns than a taxable investment. To provide more meaningful comparisons of yields and margins for all earning assets, we also provide revenue on a taxable-equivalent basis by increasing the interest income earned on tax-exempt assets to make it fully equivalent to interest income earned on other taxable investments. This adjustment is not permitted under GAAP in the Consolidated Income Statement.

The following is a reconciliation of net interest income as reported in the Consolidated Income Statement to net interest income on a taxable-equivalent basis (in millions):

We have reclassified certain prior period amounts included in this Financial Supplement to be consistent with the current period presentation. This information speaks only as of the particular date or dates included in the schedules. We do not undertake any obligation to, and disclaim any duty to, correct or update any of the information provided in this Financial Supplement.

BlackRock/MLIM Transaction

As further described in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2006, BlackRock, Inc. ("BlackRock"), then a majority-owned subsidiary of The PNC Financial Services Group, Inc., and Merrill Lynch entered into a definitive agreement pursuant to which Merrill Lynch agreed to contribute its investment management business ("MLIM") to BlackRock in exchange for 65 million shares of newly issued BlackRock common and preferred stock. This transaction closed on September 29, 2006.

For the full years 2005 and 2004 and the quarters ended September 30, 2006, June 30, 2006, March 31, 2006 and December 31, 2005 presented in this Financial Supplement, our Consolidated Income Statement reflects our former majority ownership interest in BlackRock. However, our Consolidated Income Statement for the quarter ended December 31, 2006 and our Consolidated Balance Sheet as of December 31, 2006 and September 30, 2006 reflects the deconsolidation of BlackRock's balance sheet amounts and recognizes our 34% ownership interest in BlackRock as of those dates and for that quarter as an investment accounted for under the equity method.
