UPDATE 1-Saudi bank NCB selling 2 bln riyal sukuk -sources

Saudi Arabia's National Commercial Bank (NCB) is selling a 2 billion riyal ($533.3 million) sukuk as part of its plans to raise capital. The offer, which enhances the bank's Tier 1 - or core - capital and is compliant with Basel III banking regulations, is the third such transaction by NCB since June, and is part of a plan to raise as much as 7 billion riyals of capital before the end of 2015. In the same way as the previous two issues, the latest sukuk is structured with a perpetual tenor but with a clause in the documentation which allows the bank to redeem the Islamic bond after a certain date. NCB Capital is acting as sole arranger. The transaction will be privately placed with one or more government-owned investment funds.
