ABSTRACT
This chapter addresses the evidence the company must obtain for each indicator and the means by which the evidence can be declared valid and complete, depending on the data type. In contrast, it is relatively easy to undertake bank reconciliation as it draws on strong evidenc, the company can use its bank statements and the auditor can also refer to engagement letters. There is already an excellent standard (ISA 500) for when there is evidence that can be replicated directly to provide corporate social responsibility (CSR) report data. There are degress of verifiability in financial reporting, correspondingly, there are also degrees of verifiability in CSR reporting, which allow for different types of evidence. These data types are termed 'documentable' and 'probable'. The vast majority of CSR data can be proved very strongly these are called 'documentable data'. The assumptions made to make such probable data plausible need to be recorded in writing in a memorandum.
