A total of 59 CEOs and CFOs responded in the 2008 survey (59/500: 11.8 %).
In the 2010 survey, 42 questionnaires were returned (42/500: 8.4 %). Of these
respondents, 30 executives returned both questionnaires (50.8 %/71.4 %). Table 2
outlines the characteristics of the population.
For both surveys, representativeness in terms of size and industry was proved
using the Chi squared test of homogeneity based on five-point Likert scales and
constant sum questions. The findings that follow were generated using univariate
descriptive statistics. Frequencies were analyzed in terms of the arithmetic mean
and standard deviation.
