The survey was conducted between January and March 2011 and was completed by five different types of respondents — corporates, financial investors, debt providers, government bodies and service providers. The respondents included senior executives such as chairpersons, CEOs or divisional heads. Surveyed respondents were spread across Europe (30%), North America (30 percent) and Asia-Pacific (30%), with the Middle East, Africa, and South America accounting for the remainder.
