The bank directed PricewaterhouseCoopers to remove key warnings to regulators on illicit transactions in an independent report, masking the reality of its business with the sanctioned countries, the New York State Department of Financial Services said.
PwC discovered near the end of a year-long review of transactions that the bank had issued special instructions employees to strip wire messages of information that would have triggered sanctions compliance alerts.
PwC initially drafted language warning regulators that its review had been compromised as a result of the instructions. But under pressure from the bank, part of Mitsubishi UFJ Financial Group, PwC agreed to cut that language and to replace it with a statement saying the review had been comprehensive and appropriate.
"BTMU employees pressured PwC into watering down a supposedly objective report on the bank's dealings with Iran and other sanctioned countries, thereby misleading regulators," said Benjamin Lawsky, Superintendent of Financial Services in New York.
Lawsky mandated the PwC review after fining BTMU $250 million in June 2013 over doing business with sanctioned countries.
In August, Lawsky fined PwC $25 million for its work on BTMU and banned it from accepting consulting engagements at financial institutions regulated in New York for 24 months.
