The Office of the Superintendent of Financial Institutions (OSFI) is proposing changes to the leverage ratio disclosure requirements, which aim to reflect forthcoming amendments to the leverage requirements and the capital adequacy requirements, and to capture the treatment of certain securitized assets.

Under the requirements, domestic systemically-important banks (D-SIBs) are required to publicly disclose a reconciliation of their balance sheet assets with their leverage ratio; to provide a breakdown of the main leverage ratio components; and to explain the key drivers of material changes in their Basel III leverage ratio.

The new requirements will come into effect for reporting in the first quarter of 2019, alongside the updated leverage and capital rules. Comments on the proposed changes are due Sept. 21.
