PS: CNBC's "version" of the story doesn't even mention the portion above. Their story focuses on Madoff's amazement at not being caught and his perceptions of the various SEC investigations and investigators.

Madoff: All SEC Did Before 2006 a 'Waste of Time'
Newly released documents in the Bernard Madoff case paint a detailed picture of a feckless Securities and Exchange Commission, and an epic scam artist who was constantly amazed he did not get caught.
The documents, released Friday by the SEC following an August request by CNBC under the Freedom of Information Act, include thousands of pages of e-mails, transcripts and internal SEC documents compiled by Inspector General H. David Kotz in his investigation of the SEC's handling of the case. Kotz issued a scathing report in September citing multiple lapses by the SEC in investigations dating back to 1992.
While Madoff's Scam of the Century shocked the world, it appears Madoff was mainly shocked he got away with it so long, according to a jailhouse interview he gave to Kotz on June 17 as he awaited sentencing on 11 fraud counts. In the interview, Madoff says the fact that he did not get caught was "amazing to me." Madoff was not under oath in the interview.

Out of shear boredom, I read the SEC's BernieMadoff interview posted at CNBC.

While the entire read is entertaining (from someone who did not have money invested with this thief), there is what I consider to be a gem in the bottom of page 11 and on to page 12, which I've copied below:
Wow! So that's what is meant by off-book toxic assets!
