Description of operating lease rights  
Operating rights of 20 vessels for a period of 25 years pursuant to a license agreement to Pingtan Fishing. Subsequent to the licensing of the operating rights, Pingtan Fishing is entitled to 100% operation and operating results from vessels from September 1, 2013 onwards. Hong Long was not able to transfer ownership of these 20 vessels to the Company since Hong Long received subsidies from China’s central government budget in 2012 for the construction of these 20 vessels and Hong Long received notification from the Government prohibiting the sale or transfer of ownership of these vessels for a period of 10 years for fishing vessels that have received such subsidies.
