Differences between Group and Bank
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 Swiss Universal Bank, International Wealth Management, Asia Pacific, Global Markets, Investment Banking & Capital Markets and the Strategic Resolution Unit segments. These segment results are included in Core Results, except for the Strategic Resolution Unit, which is part of the Credit Suisse results. Core Results also includes certain Corporate Center activities of the Group that are not applicable to the Bank. Certain other assets, liabilities and results of operations are managed as part of the activities of the six 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 (i) financing vehicles of the Group, which include special purpose vehicles for various funding activities of the Group, including for the purpose of raising capital; and (ii) hedging activities relating to share-based compensation awards.
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.
