Call Reports — Call.Report

The Call Report is the quarterly financial statement every insured U.S. depository institution files with the FFIEC. Three form variants differ only by institution size and foreign-office complexity; the content of the schedules inside is largely common.

Form variants

Form	Who files
031	Banks with foreign offices (any size).
041	Banks with only domestic offices, larger than $5B in total assets, or selected smaller banks.
051	Small banks (under ~$5B) with only domestic offices and routine activities. A reduced, simplified form.

The form a bank uses is recorded in the filing_type field returned by collect_filers_on_reporting_period().

Schedules

The return is organized into lettered schedules. These are the most commonly used:

Schedule	Contents
RI	Income statement.
RI-A	Changes in equity capital.
RI-B	Charge-offs and recoveries.
RC	Balance sheet.
RC-A	Cash and balances due from depository institutions.
RC-B	Securities.
RC-C	Loans and leases.
RC-D	Trading assets and liabilities.
RC-E	Deposit liabilities.
RC-F	Other assets.
RC-G	Other liabilities.
RC-K	Quarterly averages.
RC-L	Derivatives and off-balance-sheet items.
RC-M	Memoranda.
RC-N	Past-due and nonaccrual loans.
RC-O	Other data for deposit insurance assessments.
RC-R	Regulatory capital (Part I) and risk-weighted assets (Part II).

Each line item in a schedule has an MDRM code (a short identifier like RCON2170 for total assets). MDRM codes are what appear in the XBRL facsimile returned by the API.

Filing cadence

Call Reports cover calendar quarters (March, June, September, December). The filing deadline is 30 days after quarter end for most items, 35 days for certain complex items. In practice data keeps arriving for weeks past the deadline as institutions amend filings.

Quarter end	Standard deadline
March 31	April 30
June 30	July 31
September 30	October 30
December 31	January 30 (Q4 adds more complex items due February 5)

Accessing the data

The authoritative source is the FFIEC CDR. Three practical paths:

Programmatic, per-bank — collect_data(creds, rssd_id=..., series="call") returns one institution’s full facsimile (all schedules) as a list of MDRM rows.
Bulk — download the CDR bulk ZIP for a period. See Bulk files.
Web UI — the CDR public search at https://cdr.ffiec.gov/public/ returns individual-institution views. Good for sanity checks, not for pipelines.

Why submitted data changes

It is routine for an institution to refile a Call Report after the original submission. Causes include:

Internal accounting corrections.
Regulator inquiries.
Previously incomplete information now available.
Findings from examination.
Restated interpretation after regulatory guidance.

If you cache Call Report data, treat every extract as point-in-time for the extraction date, not a permanent record. Incremental updates covers how to detect refilings with collect_filers_submission_date_time().

Historical coverage

The modern XBRL facsimile goes back to 2001. Pre-2001 data exists in older formats (SAS XPORT from the Federal Reserve Bank of Chicago archives); converting it is out of scope for the FFIEC REST API and this library.
