The largest U.S. bank holding companies, including Bank of America, J.P. Morgan Chase and Citigroup, and two foreign banks Deutsche Bank and Barclays PLC must submit initial plans for "living wills" by July 1, 2012. The Dodd-Frank legislation requires financial firms to develop plans that lay out how they could be liquidated if they went under in a crisis. This legislation gives the FDIC and other regulators the power to seize and dismantle a failing financial firm, to help mitigate the problems of "too-big-to-fail" firms. The FDIC and U.S. regulators lacked such powers at the time of the collapse of Lehman Brothers in 2008. The FDIC and the U.S. Fed co-wrote the living will rule for "comprehensive and coordinated resolution planning." In all, 124 banks, including 100 foreign banks with U.S. affiliates, which have over $50 billion in assets worldwide, must submit plans and update on a regular basis. Smaller banks will have the deadline extended to December 2013.
