Abstract
Mandatory use of XBRL in financial statement filings offers a new opportunity of reading electronic filing data in the same format it was submitted to U.S. SEC. The attempt was made to read this data and to access its suitability for the financial research. In this research we read 2260 filings and attempted to use them in the complex financial calculations requiring 16 variables from Income Statement and Balance Sheet. With the requirement of having non-zero values for at least 14 out 16 variables we could only keep 25% of the statement data as suitable for research. Tree pattern used in retrieval fails because the filers use the tags outside of the designated tree and because of the use of custom tags. The amount of discarded data can be reduced by using containment pattern for describing relationship between custom tags and taxonomy tags.
