Introduction

This report filed on Form 6-K contains certain information about Credit Suisse AG to be incorporated by reference in the Registration Statement on Form F-3 (file no. 333-180300). Credit Suisse Group AG’s financial release for the first quarter of 2012 (Credit Suisse Financial Release 1Q12) is attached as an exhibit to this Form 6-K and was filed with the US Securities and Exchange Commission (SEC) on April 25, 2012. The Bank is incorporating by reference the Credit Suisse Financial Release 1Q12 (except for the sections entitled “Dear shareholders”, “Investor information” and “Financial calendar and contacts”). On or about May 8, 2012, Credit Suisse will publish and file with the SEC the Financial Report 1Q12, which will include additional disclosures on (i) fair value of financial instruments, (ii) loans, allowance for loan losses and credit quality, (iii) derivatives and hedging activities, (iv) investment securities, (v) guarantees and commitments, (vi) assets pledged or assigned, and (vii) transfers of financial assets and variable interest entities.

Unless the context otherwise requires, reference herein to “Credit Suisse Group”, “Credit Suisse”, “the Group”, “we”, “us” and “our” mean Credit Suisse Group AG and its consolidated subsidiaries and the term “the Bank” means Credit Suisse AG, the Swiss bank subsidiary of the Group, and its consolidated subsidiaries.

The Bank, a Swiss bank and joint stock corporation established under Swiss law, is a wholly-owned subsidiary of the Group. The Bank’s registered head office is in Zurich, and it has additional executive offices and principal branches in London, New York, Hong Kong, Singapore and Tokyo.

References herein to “CHF” are to Swiss francs.

The Credit Suisse Financial Release 1Q12 contains information for the three months ended March 31, 2012. The Group's independent registered public accounting firm has not completed its review of the condensed consolidated financial statements (unaudited) for the three months ended March 31, 2012 and the Group has not finalized its Financial Report for the period. Accordingly, such financial information is subject to completion of quarter-end procedures which may result in changes to that information.

Forward-Looking Statements

This Form 6-K and the information incorporated by reference in this Form 6-K include statements that constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. In addition, in the future the Group, the Bank and others on their behalf may make statements that constitute forward-looking statements.

When evaluating forward-looking statements, you should carefully consider the cautionary statement regarding forward-looking information, the risk factors and other information set forth in the Group’s and the Bank’s annual report on Form 20-F for the year ended December 31, 2011 (the Credit Suisse 2011 20-F), and subsequent annual reports on Form 20-F filed by the Group and the Bank with the SEC and the Group’s and the Bank’s reports on Form 6-K furnished to or filed with the SEC, and other uncertainties and events.

Operating and financial review and prospects

Except where noted, the business of the Bank is substantially the same as the business of the Group, and substantially all of the Bank’s operations are conducted through the Private Banking, Investment Banking and Asset Management segments. These segment results are included in Core Results. Certain other assets, liabilities and results of operations are managed as part of the activities of the three segments, however, since they are legally owned by the Group, they are not included in the Bank’s consolidated financial statements. These relate principally to the activities of Clariden Leu, Neue Aargauer Bank and BANK-now, which are managed as part of Private Banking. Core Results also includes certain Group corporate center activities that are not applicable to the Bank.

These operations and activities vary from period to period and give rise to differences between the Bank’s consolidated assets, liabilities, revenues and expenses, including pensions and taxes, and those of the Group.

Differences between the Group and the Bank businesses
Entity	Principal business activity
Clariden Leu 1	Banking and securities
Neue Aargauer Bank	Banking (in the Swiss canton of Aargau)
BANK-now	Private credit and car leasing (in Switzerland)
Financing vehicles of the Group	Special purpose vehicles for various funding activities of the Group, including for purposes of raising consolidated capital
1    Credit Suisse AG merged with Clariden Leu AG on April 2, 2012, assuming all of its rights and obligations. The process of integrating all the business activities of Clariden Leu is expected to be completed by the end of 2012.
