      "description": "Ratios computed from a company's latest snapshot by formulas with stable ids (bank.roe, corp.roic). Every value gives its unit, period and the snapshot figures it was computed from, each with its value and source document ids. Banks use the bank template (quarterly values annualised); US companies use the corporate template (annual, quarterly and trailing four quarters, ttm), which includes credit metrics, liquidity, earnings quality and forensic scores; scores, credit reconciliations and the liquidity cover also give their parts, named with their coefficients in the catalogue. A value computed with an estimated input, such as the lease cost of the latest fiscal year for quarters that do not report it, names it in estimates; a ratio that a rule leaves out for the company gives the reason in excluded. Call without ratios to list the catalogue of one frequency.",
