By sinking and dispersing the oil, BP can amortize the cost of the cleanup over the next 15 years or so, as tar balls continue to roll up on the beaches, rather than dealing with the issue now by removing the oil from the water with the proper equipment,” McCallister testified earlier this week before the U.S. Senate Committee on Commerce, Science and Transportation. “As a financial adviser, I understand financial engineering and BP’s desire to stretch out its costs of remediating the oil spill in the Gulf. By managing the cleanup over a period of many years, BP is able to minimize the financial damage as opposed to a huge expenditure in a period of a few years.”
