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 & Wealth Management and Investment Banking 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 two 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 Neue Aargauer Bank and BANK-now, which are managed as part of Private Banking & Wealth Management. 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
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
Credit Suisse AG merged with Clariden Leu on April 2, 2012, assuming all of its rights and obligations. The process of integrating all the business activities of Clariden Leu was completed in 3Q12.
