Lehman used transactions called "window dressing" as a way to show that it was burdened with less debt than a correct accounting would show. This was done through Repo 105 transactions where the bank used repurchase agreements or repos- a form of short term borrowing that lets banks take on more trading risks. Lehman lowered the repo debt at the end of each fiscal quarter. The bankruptcy examiner's report shows that Lehman moved about $50 billion in assets off its balance sheet. Lehman labeled these transactions as securities sales instead of loans, to show investors that it was actually in better shape financially than it was in reality. This was done on a quarterly basis in 2007 and 2008, according to the bankruptcy examiner's report. The New York State Attoney General's office is investigating this and the role of the auditor Ernst and Young in approving this practice, which goes back to 2001.
