Initial development of NICC was funded by the Annie E. Casey Foundation as part
of the Low Income Working Families Project. Funding for the update of the 2008
rules was provided, in part, by HHS/ASPE. Additional funding came from the John
D. and Catherine T. MacArthur Foundation. NICC’s calculations are performed by an
adapted version of the TRIM3 microsimulation model. The standard version of TRIM3
is funded and copyrighted by HHS/ASPE and developed and maintained by the Urban
Institute.
