In a strategic redesign, the Swiss lender will return the First Boston name and break up the investment bank.

The Swiss bank is looking to raise SFr4 billion ($4.05 billion) in the capital, including SFr1.5 billion from the Saudi National Bank, which would make it the group’s largest shareholder with a 9.9 percent position based on existing holdings.

Credit Suisse has also agreed to sell a portion of the operation of its securitized products to US investment firms Pimco and Apollo and spin off its capital markets and consulting company over the next three years under the rebranded CS First Boston.

Credit Suisse wants to cut risk-weighted assets in its investment bank by 40% over the next three years and focus the company on providing institutional and wealth management customers with stocks, foreign currency, and rates, according to the strategic plan.
