How this case file was put together

Every statement on this page carries a numbered note, and every note points to a court record, a regulatory filing or a named publication in the list of sources. Each statement was checked against the text of the sources it cites before it was published: a figure, a date or a name the cited source does not contain was cut rather than kept. Allegations are shown as allegations, with their status at the time of the source (filed, charged, convicted, pleaded, settled, dismissed or pending). Quoted lessons are the words of the person or publication named with them, copied from the cited source; nothing here is our own opinion of why the company failed.

If a fact on this page is wrong, use "Report an error" below and attach the record that shows the correct fact. Every report is reviewed by a person before anything changes, and a corrected page says when it was last corrected.
