Explanation

The correct answer is B. The Bankers' Trust case did NOT lead to the lesson that customers should have access to independent price quotes.

Lessons actually learned from the Bankers' Trust case:

• A: Complex transactions do make comparison shopping difficult and increase client dependency on advisors
• C: The case revealed damaging internal communications (tapes and emails) that became public evidence
• D: Some derivatives are so complex that their costs and risks outweigh their benefits

Why B is the exception:

• Bankers' Trust did NOT advocate for or implement independent price verification for clients
• The case actually highlighted the opposite problem: clients had no independent means to verify the fairness of complex derivative pricing
• Bankers' Trust maintained control over pricing and valuation of the complex instruments

Additional lessons from the case:

• Importance of full disclosure of risks in complex financial products
• Need for better understanding of derivatives by corporate treasurers
• Legal distinction between fiduciary duty and arm's-length counterparty relationships
• The reputational damage that can result from questionable sales practices

This case contributed to increased regulatory scrutiny of derivatives sales practices and better risk management standards in the industry.
