Profitability margins and balance-sheet ratios for every period: every margin and rate the record itself stores (gross margin %, operating margin %, effective tax rate, segment margins, efficiency ratio and the like), plus gross, operating, net and free-cash-flow margin, working capital and current ratio calculated here from the period's own figures, each labeled as calculated with its formula and the exact fields used, so it can be checked. A ratio is calculated only when both figures are in the same period of the same record; nothing is estimated. Every period in the latest record by default, or the periods named by period.
