Tense negotiations over a potential takeover of Switzerland's troubled Credit Suisse by the country's largest banking group, UBS, are nearing a critical juncture, with trading in the financial markets set to reopen on Monday.

Media reported that it is still on the table whether the acquisition will cover all of Credit Suisse's businesses, or only some of them.

And UBS is reportedly asking the Swiss authorities to cover losses stemming from the acquisition and future litigation costs.

Earlier on Thursday, Credit Suisse announced it was ready to take a credit line from the country's central bank to raise 54 billion dollars in emergency funds.

Market analysts say the central bank is requesting the parties involved in the acquisition to take appropriate measures with the aim of stabilizing the monetary system.
