On 22 April 2010, the United States Coast Guard and the Minerals Management Service launched an investigation of the possible causes of the Deepwater Horizon explosion they obtained and analyzed the blowout preventer, a crucial piece of evidence as to the cause of the explosion and spill.

1 April 2010 Coast Guard and Mineral Management Services investigation.Yet, in terms of financial market returns, though the stock price dropped drastically in the first two months following the spill, no statistically significant decline in the stock market returns was found either in the mid-term (1-2 years) or the long term (2-7 years). The authors add: "In the aftermath of the Deepwater accident, BP's reputation showed a serious and persistent decline. The researchers suggest a number of potential explanations for these findings and note that stock markets may not necessarily create strong-enough incentives to promote industrial safety. These findings suggest that environmental accidents can result in long-lasting declines in a company's reputation, but do not necessarily affect long-term stock market performance, nor the reputations and stock prices of similar companies. The researchers also found no evidence that the Deepwater accident damaged either the reputations or the stock market returns of other oil and gas firms. This held true for both a mid-term period of 1 to 2 years post-accident and a long-term period of 2 to 7 years. However, while BP's stock price plummeted immediately after the accident, longer-term stock market returns did not decline significantly compared to the hypothetical returns of the synthetic brand. The researchers then compared BP's actual reputation and stock performance to the synthetic brand's performance.Ĭompared to the hypothetical reputation of the synthetic brand, BP's reputation dropped by 50 percent after the Deepwater Horizon accident, and remained impaired through 2017.

To help clarify, McGuire and colleagues used a method known as a "synthetic control analysis," in which data on companies similar to BP were mathematically compiled to create a "synthetic brand" representing how BP might have fared had the accident not happened. However, the precise extent of the impact of this incident on BP has been unclear. Industrial accidents like Deepwater can cause long-lasting damage to the reputations and finances of companies. On April 20, 2010, it exploded, killing 11 workers and resulting in the largest-ever marine oil spill in US history. BP had been leasing an offshore oil drilling rig called Deepwater Horizon in the Gulf of Mexico.
