Commodity categories decline in value
Political unrest compounded the challenges of the high-risk oil and gas category, which explored for natural resource reserves in some of the earth's most difficult and fragile environments.
The Oil & Gas category declined 4 percent in brand value, the largest decline across all categories.
The steep brand value decline of Brazil's Petrobras offset the generally positive brand value improvement of both the private international oil companies (IOCs) and the state-controlled national oil companies (NOCs).
A Colombian NOC, Ecopetrol, appeared in the BrandZ™ oil and gas category brand ranking for the first time.
Russia's Lukoil also debuted in the BrandZ oil and gas category brand ranking.
