Calculation record
Portfolio EBITDA margin = total EBITDA ÷ total revenue for the selected companies and quarter. It is not the average of company percentages. EBITDA is reported, without discretionary add-backs.
Operating working capital = receivables + inventory − payables at the selected quarter end. Cash and debt are excluded in this demonstration. Closing balances are never summed across quarters.
Revenue variance = actual revenue − budget revenue. Percentage variance divides by budget. An undefined denominator displays as unavailable; a positive variance means revenue exceeded budget.
A source older than 21 days at the fixed review date is flagged. Revenue tie-out Δ is modeled revenue minus submitted source revenue; differences greater than $1 are flagged. These thresholds are demo assumptions, not a production policy.
The source IDs and fictional controller owners are retained in the download. All records use USD, one calendar, and a constant six-company perimeter. This example does not model currency translation, acquisitions, intercompany eliminations, forecasts, or actual client results.
