Measuring Accounting Reporting Complexity with XBRL

摘要: Using eXtensible Business Reporting Language (XBRL) filings, we propose two measures of accounting complexity. The first is based on the number US GAAP XBRL Taxonomy tags reported in annual financial filings. second customized (extended) created by companies when taxonomy does not include suitable to represent company-specific concepts. Based existing theory, conjecture that high volume and more unique information complicate preparation reports. We validate these examining their association with several proxies for reporting quality. find proposed complexity are strongly associated increased likelihood issuing statement restatements, disclosing material weaknesses internal controls higher level abnormal accruals. Greater also positively audit fees.
