EXPLANATORY STATEMENT

Effective December 31, 2009, the National City Savings and Investment Plan merged into The PNC Financial Services Group, Inc. Incentive Savings Plan. Also, effective January 1, 2010, participants in The PNC Financial Services Group, Inc. Incentive Savings Plan were no longer permitted to invest their contributions in The PNC Financial Services Group, Inc. (“PNC”) common stock.

Therefore, PNC and The PNC Financial Services Group, Inc. Incentive Savings Plan, as successor to the National City Savings and Investment Plan, are filing this Post-Effective Amendment No. 1 to the Registration Statement to deregister Plan interests that were registered thereunder for the National City Savings and Investment Plan and to deregister remaining shares of PNC common stock issuable under this Registration Statement insofar as they are issuable in connection with the National City Savings and Investment Plan.

PNC is acting pursuant to the power conferred on PNC in accordance with the provisions of Rule 478 under the Securities Act of 1933, as amended, to reduce the amount of securities registered, pursuant to its undertaking contained Part II, Item 9 of the Registration Statement, as initially filed on January 22, 2009.

This Post-Effective Amendment No. 1 to the Registration Statement does not in any way amend the Registration Statement as it applies to the other two Plans for which securities have been registered thereunder, namely The PNC Financial Services Group, Inc. Supplemental Incentive Savings Plan (“SISP”) and The PNC Financial Services Group, Inc. and Affiliates Deferred Compensation Plan (“DCP”), and does not in any way reduce the amount of securities registered in connection with those two Plans and does not in any way reduce the Deferred Compensation Obligations issuable under the Registration Statement in connection with those two Plans.
