# Backlog / Remaining Performance Obligations

`GET /api/footnotes/backlog`

![Pro](https://img.shields.io/badge/Pro-8b5cf6)

Returns remaining performance obligations (RPO), the contracted revenue not yet recognized, the closest thing GAAP has to a bookings number, plus the share the filer expects to recognize within its disclosed window. Comparing RPO growth to revenue growth is the classic bookings-momentum signal for subscription and long-contract businesses.

Monetary values default to **US dollars** (`currency` parameter as on the statements endpoints, `fx` audit block, `currency=original` for as-filed). `expectedShareInWindow` is a fraction of 1 and never converted.

**What this data can tell you:**
- RPO growth vs revenue growth as a forward demand signal.
- Contracted revenue coverage: RPO relative to annual revenue.
- Changes in the share expected to convert near-term.

**Data honesty notes:**
- Coverage is roughly 15% of active filers, driven by ASC 606 adoption; companies without long-term contracts rarely tag it.
- The expected-timing breakdown by future year is tagged with date-typed contexts that are not reliably numeric; this version serves the total and the disclosed-window share, and says so.
- Mis-tagged whole-percent shares are re-scaled and flagged `normalized: true`.

## Query parameters

- `symbol` string
- `cik` integer
- `cusip` string
- `composite_figi` string
- `share_class_figi` string
- `currency` string
- `period` 'annual' | 'quarter' — Base reporting period: `annual` or `quarter` (the periods companies actually report, without the derived `ttm` rollup).
- `limit` integer

## Response `200`

RPO per period

- object[]
  - `period` string, date — The fiscal period end date (YYYY-MM-DD)
  - `fiscalYear` integer
  - `fiscalPeriod` 'FY' | 'Q1' | 'Q2' | 'Q3' | 'Q4' — Fiscal period of a reported value: `FY` (annual) or `Q1`-`Q4` (quarterly).
  - `currency` string, nullable — Currency of the RPO after conversion; null when unconverted (see `fx.unconverted`)
  - `normalized` boolean — Only present (as `true`) when the share was re-scaled from a mis-tagged whole percent.
  - `remainingPerformanceObligation` number — Total contracted revenue not yet recognized, at period end
  - `expectedShareInWindow` number — Share of the RPO the filer expects to recognize within its disclosed window (fraction of 1). The window length itself is prose, not XBRL.
  - `dateFiled` string, date, nullable — SEC filing acceptance date of the newest filing contributing to this period. Use this to gate point-in-time data and avoid lookahead bias.
  - `fx` FxConversion — Foreign-currency conversion audit for this period. Every monetary value in `facts` is in the requested `currency` (default **US dollars**). This block is absent when the period was already wholly in the target currency (e.g. a US filer with the default USD, nothing to convert). It is present when one or more line items were originally filed in a different currency and converted on the fly, and it records the exact rate(s) applied so the conversion can be reproduced. Rates come from the Frankfurter API (api.frankfurter.dev). Instant balance-sheet items use the spot rate at period end; flow income/cash-flow items use the day-weighted average rate over the period.
    - `targetCurrency` string, required — The currency (ISO 4217) every `facts` value was converted INTO, the value of the request `currency` parameter (default USD). The literal `original` here means no conversion was requested: each fact stays in its as-reported currency (see `unconverted` for the per-fact mapping).
    - `originalCurrencies` string[], required — Every source currency (ISO 4217) that appeared in this period, the union of converted, unconverted, and already-in-target. The target currency itself is listed when some facts were natively in it (e.g. a foreign filer reporting some lines in USD alongside its converted local currency), so a mixed period reflects its true composition rather than appearing wholly converted.
    - `rates` object[], required — One entry per (source currency, method) actually applied. `rate` is the multiplier: `target = original * rate`.
      - `from` string, required — ISO 4217 source currency that was converted.
      - `method` 'spot' | 'average', required — `spot` for instant balance-sheet items (rate at period end); `average` for flow income/cash-flow items (day-weighted mean over the period).
      - `rate` number, required — Multiply the original-currency amount by this to get the `targetCurrency` amount.
      - `effectiveDate` string, date — Spot only: the date (YYYY-MM-DD) the applied rate was published (≤ period end).
      - `start` string, date — Average only: period start (YYYY-MM-DD).
      - `end` string, date — Average only: period end (YYYY-MM-DD).
    - `unconverted` object — Facts that could NOT be converted (no published rate within tolerance, or an unsupported code/date), grouped by the currency they remain in: each key is a source ISO 4217 code, each value lists the curated fact names in `facts` still in that currency (NOT `targetCurrency`). Absent when everything converted. Use it to know exactly which figures to treat as native currency.
