Globally, companies increasingly publish separate general purpose, nonfinancial (sustainability) reports. Some of these are independently assured and assurers may or may not be from the auditing profession. We seek to understand this emerging voluntary assurance market. Using a sample of 2,113 companies (from 31 countries) that produced sustainability reports between 2002–2004, we use sequential logit analysis to identify the factors associated with the decision to voluntarily purchase assurance and the choice of assurance provider. We hypothesize that a company's need to enhance credibility through assurance and choice of assurance provider will be a function of company-, industry-, and country-related factors. Our results support the argument that companies seeking to enhance the credibility of their reports and build their corporate reputation are more likely to have their sustainability reports assured, although it does not matter whether the assurance provider comes from the auditing profession. We also find that companies operating in stakeholder-orientated countries are more likely to choose the auditing profession as an assurer.

Rotation of audit partners is one of the main policy initiatives that has been implemented in many jurisdictions around the world to deal with concerns about audit quality. The basis of any requirement limiting the tenure of audit partners is that there is a reduction in audit quality associated with long periods of tenure. Using data from Australia, where the audit partner can be identified and for a period where partner rotation was not mandatory, we examine the association between audit quality and long audit partner tenure. The three measures of audit quality examined are the auditor's propensity to issue a going-concern audit opinion for distressed companies, the direction and amount of abnormal working capital accruals, and just beating (missing) earnings benchmarks. For long tenure observations we find a lower propensity to issue a going-concern opinion and some evidence of just beating (missing) earnings benchmarks, consistent with deterioration in audit quality associated with long audit partner tenure. There is no evidence of an association of long audit tenure with abnormal working capital accruals.

SUMMARY This paper describes the current environment for assurance services for corporate social responsibility (CSR) performance. It then discusses opportunities for research, and highlights areas that are evolving as significant research opportunities and areas of significance that have been under-researched in the past. Finally, the paper reviews the five papers in the forum and highlights how multiple methodologies may be appropriate to examine different aspects of assuring CSR reporting from both internal and external assurance perspectives.

SUMMARY This study reports the results of a behavioral experiment examining whether financial analysts from Australia, the United States, and the United Kingdom perceive a difference in the credibility of stand-alone corporate social responsibility (CSR) reports depending on whether they are assured, and the type of assurance provider (professional accountants versus sustainability consultants). We further examine whether the perceived credibility differs for financial analysts from the different countries and whether results hold for companies from different industries. The overall results show the credibility of a CSR report is greater when it is assured and when the assurer is a professional accountant. While assurance increases the credibility of the information in each of the three countries included, the relative impact is context-specific. Information is perceived to be more credible when a company is from an industry where assurance is more commonplace, and by financial analysts from the United States when the assurer is a professional accountant. Financial analysts from Australia and the United Kingdom perceive little difference in the enhanced credibility provided by the different assurance providers.

Integrated reporting () is an emerging international corporate reporting initiative to address limitations to extant corporate reporting approaches, which are commonly criticized for being both voluminous and disjointed. While is gaining in popularity, current momentum has been limited due to a lack of clear evidence of its benefits. Utilizing the most suitable setting currently available, being discretionary disclosures made by listed companies on the Johannesburg Stock Exchange, this study provides evidence that analyst forecast error reduces as a company's level of alignment with the framework increases. Further, the improved alignment is associated with a subsequent reduction in the cost of equity capital for certain reporting companies. The results are obtained after controlling for factors relating to financial transparency and the issuance of standalone non-financial reports, which suggests that is providing incrementally useful information to the capital market over and above existing reporting mechanisms.
