also contributes to the TBL reporting, and social and environmental accounting literature,
because it provides insights into the TBL reporting, and social environmental disclosure
practices of listed companies with respect to their operations within developing countries
where there have to date been a limited number of published studies (M. A. Islam & C.
Deegan, 2010).
There are some limitations associated with the method adopted in the study. First, the sample
consisted of only the Top 50 Thai companies; intuitively if disclosures are to be made, these
are the most likely companies to make them. However, the results may have been different if
the composition of the sample was different and sampled both large and smaller companies.
Second, there may be scope for explaining the extent of TBL reporting by using other
variables. Further research is needed to compare the TBL disclosure practices of Thai listed
companies in other media such as websites and/or stand-alone reports; to ascertain why
voluntary disclosures are made, and whether disclosures are related to firm performance.
