Occidental's local purchasing programs seek to enhance the competitiveness of contractors and suppliers and their ability to meet the company's quality, environment and safety performance requirements. We work closely with our local suppliers to ensure sustained quality of service and provide additional training to some suppliers. Maximizing our use of vendors based in the countries where we operate leads to increased job creation and economic opportunities for local residents. Occidental's purchasing activity represents tens of millions of dollars in revenue for local businesses annually.

With relatively few vendors based in the towns near Occidental's operations, Occidental Colombia has continued to expand its program, first initiated in 2009, to strengthen the business capabilities of local vendors in the communities near Occidental's operations. Occidental has trained dozens of qualified local companies on management, finance and administrative topics. Every participating company receives a tailored development plan following an assessment of its strengths and needs.
Occidental Colombia's Contractor Strengthening Program supports 20 local suppliers working in the La Cira-Infantas (LCI) field that are certified under the Uniform Registration of the Health, Environment and Safety Assessment System for Contractors, or RUC. To further enhance business opportunities for local vendors, Occidental Colombia also provides its contractors working in the LCI Field with a consolidated list of local suppliers and subcontractors. This promotes networking, the use of local products and services, and ultimately enhances economic opportunities for local businesses near Occidental's operations. As a result of these efforts and others, local purchasing among Occidental Colombia's contractors in the LCI Field has increased more than 300 percent since 2012.
