Tables are calculated by averaging the ratings for each individual category.
In the lead categories, each voters top bank was awarded four points, the second-placed three points, and third-placed two points. Each voters score was then weighted depending on the annual gross sales of the part of the business for which the voter was responsible, as follows:
Greater than $100 billion a factor of 10 was applied;
$25 billion to $99.99 billion a factor of 9 was applied;
$10 billion to $24.99 billion a factor of 8 was applied;
$5 billion to $9.99 billion a factor of 7 was applied;
$2.5 billion to $4.99 billion a factor of 6 was applied;
$1 billion to $2.49 billion a factor of 5 was applied;
$500 million to $999.9million a factor of 4 was applied;
$100 million to $499.9 million a factor of 3 was applied;
$50 million to $99.9 million a factor of 2 was applied;
Less than $50 million a factor of unity was applied.
Treasurers votes were aggregated to include subsidiaries and regions where appropriate.
Estimated aggregate gross sales for the survey, based on the midpoint of each band, is $14.4 trillion
Respondents can tick one (and only one) of the following sections when completing the poll:
1 global and 1 region;
1 region and 1 domestic; and
This year we received 18,848 replies to the survey in total. Of these, 5,504 were deleted during the verification process, leaving 13,344 valid responses, up from 6,238 in 2008 (an increase of more than 100%). The main reasons for deletion were insufficient contact details, multiple responses from the same firm and irregularities in the data given.
Geographical breakdown of all votes received (figures for 2008 in brackets) was:
Asia 49.55% (63.24%), Europe 26.2% (16.63%), Middle East & Africa 18.29% (13.02%), Latin America 3.54% (2.37%), North America 2.43% (4.74%)
