BERLIN, Rabi'I 28, 1437, Jan 8, 2016, SPA -- The Swiss National Bank said it expects a loss of 23 billion Swiss francs ($23 billion) for 2015, AP reported. A loss of about 20 billion francs resulted from the drop in the value of the bank's foreign currency holdings. The SNB said in a statement Friday that it booked a further 4 billion loss due to declining gold prices, but gained 1 billion francs from its Swiss currency holdings. --SPA 12:33 LOCAL TIME 09:33 GMT www.spa.gov.sa/w
