WASHINGTON, April 14 (Reuters) - The Federal Reserve's Board of Governors on Friday said it has approved UBS Group AG's acquisition of the U.S. subsidiaries of Credit Suisse, clearing another major hurdle for the completion of the Swiss-brokered rescue deal. UBS has committed to give the U.S. central bank an implementation plan for combining its U.S. business and operations with those of Credit Suisse within three months of consummating the deal, the Fed's Board said in a statement. UBS agreed to buy Credit Suisse for 3 billion Swiss francs ($3.3 billion), a fraction of its earlier market value. UBS has said it expects the deal to create a business with more than $5 trillion in total invested assets. Under the takeover deal, holders of Credit Suisse AT1 bonds will get nothing, while shareholders, who usually rank below bondholders in compensation terms, will receive $3.23 billion.
