Actual selection tier: Same NTEE sector (B90) + MA + size band 0.67–1.5× revenue. Displayed D + F figures from supported filing years are indexed to 2025 comparison dollars with BLS CPI-U; a nationwide tier also uses 2024 BEA RPP as a consumer price-level proxy when both the subject and peer have supported state codes. Unsupported state codes receive no interstate adjustment. Comparison values can differ from the raw filing. Column F may include related-organization amounts.
