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.
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 (FISN CIK 0001918102),
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.
