Interactive: CDOs’ Interlocking Ownership

Correction, Sept. 22, 2010: This post previously reported that there were 85 instances during 2006 and 2007 in which two complex securities known as collateralized debt obligations bought pieces of each others' "unsold" inventory.

A CDO called Tourmaline III made a sidebet in 2007 that mirrored the performance of a piece of a CDO called Zais Investment Grade 8; that same year Zais 8 bought a piece of Tourmaline III. Both CDOs were underwritten by Deutsche Bank.
