NOTE: Benchmark plans are not shown for the territories because low-income beneficiaries residing in the territories are not eligible for the low-income subsidy. Estimates in some years/states include “de minimis” plans, which can retain Low-Income Subsidy beneficiaries despite exceeding the benchmark premium by a minimal amount (up to $2 in 2018).
