People ride a boat on an artificial lake at the Dubai Mall area in Dubai March 15, 2014. Dubai's Emaar Properties said it would sell up to 25 percent of its shopping mall and retailing unit in a public offer expected to raise 8 to 9 billion dirhams ($2.18-$2.45 billion), making it one of the region's largest equity offers since 2008. Dubai-listed Emaar's flagship mall is the Dubai Mall, one of the largest in the world, which it says attracted more than 75 million visitors in 2013. The company also built the Burj Khalifa in Dubai, the world's tallest building. REUTERS/Saleh Salem (UNITED ARAB EMIRATES - Tags: CITYSCAPE BUSINESS REAL ESTATE)
