As we describe in our CDO investigation published last week with our partners at Planet Money, the inner workings of Wall Street’s world of structured finance are complicated.

While we hope to have shed light on the subject, we’re under no illusion that our 5,000-word investigation (and its accompanying charts, song, comic, and crib sheet) has answered all your questions about a rather dim corner of the financial world.

If you’ve got questions, send them to us. And just as we did with our Magnetar investigation, we’ll take the most frequently asked questions and supply the answers as best we can.
