The main business activity of ST Engineering relates to management and execution of projects for defence and commercial customers. Risks relating to project management are therefore inherent in the business. These may include issues relating to project costs and schedules, as well as contractual and quality matters. The Group has a project review and quality assurance system in place to mitigate such risks. All contracts of material value require review by legal counsel, and significant deviations from pre-approved standard contract terms and conditions are to be highlighted and presented to higher levels of management for review and approval.
