Asya Katilim Bankasi AS (ASYAB), the Turkish banks in talks to sell a stake to Qatar Islamic Bank, has hired Goldman Sachs Group Inc (GS:US) as exclusive financial adviser on the deal. The Istanbul-based lender said in March that it was in exclusive talks with QIB for a strategic partnership, while the Doha-based bank said it was interested to take a stake in the lender. Bank Asya, in today’s filing, didn’t give more details. Bank Asya fell 2.9 percent to 1.66 liras at 10:35 a.m. in Istanbul. It’s gained about 14 percent this year.
