A worried accounting executive at Lehman Brothers, who raised the alarm about what he saw as dubious number-crunching at the doomed Wall Street bank, lost his job barely a month after alerting the auditor Ernst & Young, his lawyer [has] claimed. Matthew Lee, a senior vice-president in Lehman's finance division, outlined six allegations of unethical accounting in a memo sent on 16 May 2008 to Lehman's senior managers, who asked Ernst & Young to investigate. In discussions with partners at Ernst & Young, he highlighted controversial repo 105" transactions that artificially boosted Lehman's balance sheet by $50bn. Lee's lawyer, Erwin Shustak, said his client lost his job in late June 2008, officially as part of a broader downsizing. Shustak told the Wall Street Journal: "It was just easier to shut him up and let him go." Lee, 56, has emerged as a crucial figure in Lehman's downfall and in controversy over the conduct of Ernst & Young. The six allegations made by Lee included claims that Lehman's monthly balance sheet listed $5bn of assets above reality, that the bank failed to value its inventory of financial products in a "fully realistic or reasonable" way, that audit-level personnel were inadequately qualified, that systems were ineffective and that there were "tens of billions of dollars" of possibly toxic liabilities.
