All First Federal Reserve District top-tier holding companies must file the FR Y-6 report annually as of the date of their fiscal year-end. The FR Y-6 requires the submission of an organizational chart and an annual verification of domestic branches within the organization, and includes information on the identity, percentage ownership, and business interests of principal shareholders, directors, and executive officers. The reports are due to this Reserve Bank within 90 days of a holding company's fiscal year-end and are posted here when the Reserve Bank has completed its review of the data.

Pursuant to the Freedom of Information Act and the regulations promulgated by the Board of Governors of the Federal Reserve System, selected information may be redacted from the reports based on the granting of a holding company's request for confidential treatment by the Federal Reserve Bank of Boston.
