This is what a multinational company looks like..
My friend Skye Bender the Moll has developed a software (SONIA) to dynamically visualize network movie and a database (CorpWatch) of subsidiary relationship information from Exhibit 21 of companies' 10-K filings.
Click here for a movie of the changes in corporate structure at Lehman Brothers from 2003-2008. Each dot is a subsidiary corporation and each line is a declared ownership relation.
Goldman Sachs movie The “ring” of nodes around the main network are companies with names that include “Goldman Sachs” but are not reported in the main filings. Since these must be associated in some way with Goldman Sachs, but we don’t have any ties for them, it kind of gives an idea of how many relationships we are “missing”– the Exhibit 21 filings are just the tip of the glacier, lots of other little icebergs floating around out there.
Lehman movie does not have 2009 data (will they ever? ;-). When the 2009 data is complete, I wonder if we will be able to locate their sold-off divisions now belonging to other companies?
Coca Cola movie. Started from a query looking for names like “Coca Cola”, so it includes the “Coca Cola Bottling” and “Coca cola Enterprises” divisions that are legally separate corporations even though they are controlled by the parent.
