London-based European Islamic Investment Bank said on Tuesday it plans to close a proposed 20 million pound ($30.5 million) tender offer for its own shares in May as it transitions into an asset management business model. In February, the sharia-compliant firm said it had received regulatory approval to relinquish its banking licence and is now an investment firm regulated by the Financial Conduct Authority. EIIB plans to invest $1 billion in a mix of property transactions over the next 24 months. It held $1.1 billion in assets under management as of December. The firm posted a pre-tax operating profit of $2.3 million in 2014 compared with $2.23 million profit a year earlier.
