Analyst Notes
This projection model for South employers uses composite rate data derived from CMS Medical Loss Ratio (MLR) filings and MEPS-IC survey results. The fully insured baseline reflects South-specific community rating adjustments where applicable, while self-funded projections incorporate stop-loss premium estimates from the Self-Insurance Institute of America (SIIA) benchmarking data. PEO rates are modeled using aggregated large-group purchasing power discounts typically ranging from 8-22% depending on industry classification and claims history.
Rate trend assumptions for South are based on a blended index of KFF Employer Health Benefits Survey data, Milliman Medical Index growth rates, and state-specific regulatory filings. The captive insurance projections assume a minimum of 50 participants in a group captive structure with appropriate reinsurance attachment points. Employers with favorable loss ratios (under 65%) may see additional savings not fully captured in these directional estimates.
For a detailed actuarial review specific to your company's demographics, claims experience, and risk tolerance, contact our analysis team. Plan design changes (deductible levels, copay structures, network breadth) can shift these projections by 15-30% in either direction.
