Export fields and identifiers
Use supporting fields to interpret, join, filter, normalize, and audit exported metrics.
Primary document identifier
Use earningscallID as the public document identifier in user-facing documentation.
Do not use nla_id as the primary public identifier.
Documented supporting fields
| Field | Definition |
|---|---|
earningscallID | Unique identifier for each earnings-call document in the main exported CSV files. |
nr_of_sentences | Total number of sentences in the earnings-call transcript. |
date | Date of the earnings call, based on UTC time. |
start_time | ISO 8601 timestamp for when the earnings call started, in UTC. |
date_q | First day of the calendar quarter during which the earnings call was held. |
company_name | English company name for the earnings-call company. |
headquarterscountry | Registered country of the earnings-call company. |
tickersymbol | Ticker symbol for the company holding the earnings call. |
isin | International Securities Identification Number. |
cik | SEC Central Index Key, relevant for U.S. entities where available. |
trbc | Thomson Reuters Business Classification code. |
economic_sector | English-readable label for the first two digits of trbc. |
business_sector | English-readable label for the third and fourth digits of trbc. |
event_name | Name of the earnings-call event. |
Use start_time when precise timing matters. date_q is a calendar quarter field, not a fiscal quarter field.
Identifier caveats
Identifier availability can vary by firm, market, source, or export. Availability rules for RIC, GVKey, and crosswalk-only fields still need confirmation before they can be documented as always present.
When joining to downstream datasets, check the actual export fields and document the join key used.
GVKey crosswalk
The GVKey crosswalk is offered as a convenience for users joining NL Analytics output to Compustat.
Treat the crosswalk as an input to verify, not as a guaranteed match. Check the match quality before relying on joined results. The crosswalk may use identifiers such as CIK, ISIN, ticker, and exact or fuzzy company-name matching.
Schema caveat
This page lists approved supporting fields, not an authoritative file schema. Do not infer CSV filenames, exact column ordering, optional sentence-download fields, or availability guarantees from this page.
