Audit opinion is not necessarily absolute due to constraints inherent in any audit work, including sampling, different convincing degrees of audit evidence, accounting system and internal control characteristics, as well as inherent constraints of accounting measurement. The information contained in audit reports is used to forecast corporate bankruptcy; therefore, the auditor's opinion influences the views of users of financial statements. Financial status of a business can be assessed using financial ratios. The circumstances considered by an auditor in commenting on financial distress including financials (in particular, short-term liquidity, ability to repay and debt tolerability), and operations (profitability and ability to generate cash from operations). This study uses an integrated ANN-PSO to forecast audit opinion. The results show that ANN-PSO is more useful, because PSO algorithm can optimise hidden layers and neurons in ANN simultaneously. Finally, ANN-PSO outperforms ANN.
One of the effective factors on economical growth and development is efficient investment and one of the effective factors on efficient investment is conservatism; therefore, the target for this study is to investigate the relation between conditional and unconditional conservatism & investment opportunities which is surveyed by screening 122 samples between 2009-2013 in accepted companies by stock exchange in Tehran.This study is a practical research which is based on inductive-apriority reasoning. The nature and content of research method is related to correlation and for finding this correlation between variables, we shall use ego-event style. with refer to the analyze done on results, this study shows that there is a direct and significant relation between conditional conservatism and investment opportunities, but no significant relation can be found between unconditional conservatism and investment opportunities.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
