seams What this is built from Where this stops short IRS Form 990 filings, 2015–2025, for World Class organizations, pulled corps by corps and year by year from ProPublica's Nonprofit Explorer. DCI Inc.'s own Form 990 filings (EIN 36-2754480). Cost analysis covers the eight corps-only filers: Bluecoats, Crown, Phantom, Blue Stars, Colts, Troopers, Cavaliers, Crossmen. Growth over time covers six of those — the Cavaliers changed fiscal year and the Colts' earliest filing is 2019, so neither has a 2016 baseline. DCI finals placements, matched to each organization's fiscal year, scored competitive performances only. DCI's published Policy Manual for payment rates, plus its bylaws and 2017 strategic plan for governance language. Inflation is CPI-U annual averages, about 31% from 2016 to 2024. 990 expense categories are each tax preparer's labels, not a standard. Cross-corps comparisons of any category are approximate at best. That is the finding, not a disclaimer. The form itemizes only the four largest other expenses and sweeps the rest into an unlabeled line no method can see into. Touring growth is therefore a range, roughly 67% to 93%. People costs are a floor, not a ceiling: instructor pay at some corps cannot be separated from other spending. Blue Devils, Boston, Vanguard, Madison and Blue Knights file under umbrellas carrying a second ensemble, an education arm or event production, so their corps cannot be separated out and they sit out the cost analysis. Three of the eight that remain run a side business inside the same return — bingo at Bluecoats, instrument sales at Carolina Crown, gaming at Troopers. Reported net, so the gross never shows, but the overhead is not separable from the corps. Gaming revenue is reported net, so gaming staffing appears nowhere in expense totals. No figure here implies wrongdoing by anyone. Every number is as the organizations reported it. Every line item behind these figures is available on request. The full write-up, including the correction that reshaped it, is published in the Follow the Money series.
