The 2008 Bribe Payers Survey is a survey of senior business executives that includes a wide range of questions about the nature, scope and impact of bribery and corruption. The 2008 Bribe Payers Survey interviewed 2,742 respondents in 26 countries. It was designed and commissioned by Transparency International and implemented on behalf of Transparency International by Gallup International Association.

• Foreign-owned: 20 percent or more of a firm’s capital is owned by a foreign company.
