About these numbers

Remaining performance obligations (RPO) are revenue a company has contracted but not yet recognised, as reported in its SEC filings (XBRL tag RevenueRemainingPerformanceObligation). Coverage = backlog ÷ trailing twelve-month revenue. Book-to-bill = (change in backlog + revenue) ÷ revenue. Conversion = revenue recognised ÷ the backlog at the start of each quarter, summed over four quarters. Counterparty values come from company filings and releases.
