A bill to amend the Act of May 19, 1947, chapter 80, section 3, 61 Stat. 102, as amended (25 U.S.C. 613) to permit per capita payments from excess tribal trust funds of the Shoshone and Arapahoe Indian Tribes in Wyoming.

Amends the provision of law dealing with Shoshone and Arapahoe Indian tribal funds to require the Secretary of the Interior to make per capita payments of the yearly interest accruals to those tribes,. Directs the Secretary to add to the distribution fund of those trusts as much of that fund in excess of $1,000,000 as is needed (1) to prevent a decrease in per capita payments and (2) to increase, if necessary, those payments by a sum not to exceed 20 percent of the per capital for the preceding year.
