Credit Suisse announced it will be borrowing up to 50 billion Swiss francs ($53.68 billion) from the Swiss National Bank under a covered loan facility and a short-term liquidity facility.

The decision comes shortly after shares of the lender fell sharply Wednesday, hitting an all-time low for a second consecutive day after its top investor Saudi National Bank said it won't be able to provide further assistance.

The latest steps will "support Credit Suisse's core businesses and clients as Credit Suisse takes the necessary steps to create a simpler and more focused bank built around client needs," the company said in an announcement.

In addition, the bank is making a cash tender offer in relation to ten U.S. dollar denominated senior debt securities for an aggregate consideration of up to $2.5 billion – as well as a separate offer to four Euro denominated senior debt securities for up to an aggregate 500 million euros, the company said.
