"S. 407 would increase the amounts paid to veterans for disability compensation and to their survivors for dependency and indemnity compensation by the same cost-of-living adjustment (COLA) payable to Social Security recipients. The increase would take effect on December 1, 2009, and the resulting adjustment would be rounded to the next lower dollar. […]S. 407 contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act and would not affect the budgets of state, local, or tribal governments."
