TABLE A-1.

Average Difference in Cost between Baseline Plan and Lowest-Cost 2007 Plan

	Dollars		Percentile Rank
	Potential	Actual	Potential	Actual
	(1)	(2)	(3)	(4)
Among Basic Plans	−386	−337	38	35
Among Enhanced Plans Without Gap Coverage	−429	−391	43	37
Among Enhanced Plans With Gap Coverage	−464	−392	50	49
Among All Plans	−527	−487	39	37

Notes. The baseline plan is the plan in which the individual was enrolled in 2006. The dollar difference is the cost in 2007 of lowest-cost plan minus that of the baseline plan. The percentile rank the rank of the cost of the lowest-cost plan minus the baseline plan (where zero provided the most savings and 100 provided the least savings). The sample for rows 1–3 is limited to plans of the same type as the baseline plan. The sample size for potential costs was 224, 73, 109, and 406 for rows 1–4 respectively in columns 1 and 3; for actual costs it was 155, 58, 85 and 298 for those rows in columns 2 and 4.
