Raw XBRL tagging for a single filing

Every us-gaap and custom concept the filer tagged for one fiscal period, grouped by statement. Start here when a number in the trend table above surprises you and you want to see the exact tag behind it. Derived and valuation rows are omitted here because they already appear in the trend table.

Most recent filing shown by default.

Compare filings side-by-side

Diff any two filings with deltas and added / removed tags.

Immaterial rows are USD line items under 1% of the period's revenue — the noise floor below which a single tag rarely moves the investment thesis. Revenue is read from the filer's top-line concept (Revenues / RevenueFromContractWithCustomerExcludingAssessedTax, with a fallback chain). Non-USD rows, rows without a numeric value, and every row on a filing with no identifiable revenue anchor stay visible. Flip the switch off to see every tag the filer reported for the period.

Methodology

All facts on this page come straight from SEC EDGAR XBRL company-facts filings (RMBS CIK 0000917273), grouped by financial statement using FASB's base us-gaap presentation taxonomy. Filers may re-parent concepts onto different statements in their own extension taxonomy, so a handful of rows can show up under a different statement than on the actual 10-K / 10-Q; custom concepts and any we couldn't map fall into Other. Hover a cell to see the fully-qualified concept name and the filer's description.

For the full methodology — statement grouping, the Other bucket, derived metrics, and fact tooltips — see the methodology reference for the statement grouping, the "Other" bucket, derived metrics, and fact tooltips.
