United States government assistance is the mainstay of the economy. Under terms of the Amended Compact of Free Association, the U.S. is committed to provide US$57.7 million per year in assistance to the Marshall Islands (RMI) through 2013, and then US$62.7 million through 2023, at which time a trust fund, made up of U.S. and RMI contributions, will begin perpetual annual payouts.
