Since 2008, Somali pirates centered in the Gulf of Aden made about $120 million annually, reportedly costing the shipping industry between $900 million and $3.3 billion per year. By September 2012, the heyday of piracy in the Indian Ocean was reportedly over. Backers were now reportedly reluctant to finance pirate expeditions due to the low rate of success, and pirates were no longer able to reimburse their creditors. According to the International Maritime Bureau, pirate attacks had by October 2012 dropped to a six-year low. Only five ships were captured by the end of the year, representing a decrease from 25 in 2011 and 27 in 2010, with only one ship attacked in the third quarter compared to 36 during the same period in 2011. However, pirate incidents off on the West African seaboard increased to 34 from 30 the previous year, and attacks off the coast of Indonesia rose from 2011's total of 46 to 51.
