Energy supply contracts (Gas, electricity, etc.)

The Group's subsidiaries in Egypt had entered into agreements for the purchases of certain minimum quantities of gas in the subsequent years. As of 2014, the state company of natural gas in Egypt does not supply gas, due to lack of reserves. In the last two years, the Group's subsidiaries had no obligation to pay and they did not pay the agreed minimum quantities. There is no indication that the gas supplier will have the capacity to supply gas in the foreseeable future.

Also, the Group's US subsidiaries have entered a contract to purchase raw materials and manufacturing supplies as part of their on-going operations in Florida. This includes a contract to buy construction aggregates through a multi-year agreement at prevailing market prices.
