XBRL mandated in the US – we finally got there
XBRL – promoted by the SEC under the name interactive data - lets standardised accounting data be tagged and retrieved more easily. They can be read by software, screened for specific data, and reorganised. In theory, buy and sell side will be able to create and update their models automatically when they've been tagged using XBRL.
And potentially XBRL could be translated into terms used by different countries' accounting systems, enabling a true like for like comparison between international companies.
Back in the 1980’s – showing my age again – I worked with others on the “Extel card”. This was a printed format that captured the (pre IFRS) financials from mainly UK and European companies. However, the data always suffered from the lack of comparability. Analysts who wanted to compare peer companies across borders had to construct their own models and restate the financials of each company to be compared.
When the Extel card became computer readable, the search was on for ways of doing this global comparison automatically. Names like Global Vantage and Worldscope reflect that era. None however worked effectively, still requiring manual intervention.
This weeks announcement, taken together with the completed IFRS and US GAAP taxonomies (dictionaries) and the growing mandatory use of XBRL in Europe – notably EXCLUDING so far the UK - moves the automated ‘global comparison’ vision a stage nearer.
The changing fortunes and business model of investment banks have led to a reduction in numbers of companies followed. At the same time, to judge by the attendance on the IR courses and seminars that I run, growing numbers of emerging markets companies seeking international capital, and hence needing analyst coverage. XBRL efficiencies should provide that coverage.
This might just be the start of a new era.
