Global holds the overseas interests - all of them in Latin America - to controversial, George Bush-linked US oil group Harken Energy (which still holds 94% of Global shares). Interim results showed a reduction in pre-tax profits from $3m (£1.9m) to $494,000 in the six months to June. Expenditure was cut and turnover decreased from $4.6m to $4m. Global has production interests in Colombia, plus exploration interests in other Latin American countries. It expresses optimism about the future, given higher oil prices, so profits could be forthcoming. Despite this, there seems little reason to buy in.
