  • Type of publication: Guideline
  • Date: September 2023
  • Effective date: November 1, 2023

Subsection 485(1.1) of the Bank Act requires domestic systemically important banks (D-SIBs) to maintain a minimum capacity to absorb losses. The purpose of the Parental Stand-Alone (Solo) Total Loss Absorbing Capacity (TLAC) framework is to ensure a non-viable D-SIB has sufficient loss absorbing capacity on a stand-alone, or solo, legal entity basis to support its resolution. This would, in turn, facilitate an orderly resolution of the D-SIB while minimizing adverse impacts on the stability of the financial sector, ensuring the continuity of critical functions, and minimizing taxpayers’ exposure to loss.

This guideline is not made pursuant to subsection 485(2) of the Bank Act. However, the standards set out in this guideline together with the requirements set out in the Total Loss Absorbing Capacity (TLAC) Guideline, the Capital Adequacy Requirements (CAR) Guideline and the Leverage Requirements Guideline provide the framework within which the Superintendent will assess whether a D-SIB maintains its minimum capacity to absorb losses pursuant to the Bank Act.

For this purpose, the Superintendent has established the risk-based Solo TLAC ratio, which builds on the risk-based TLAC ratio set out in the TLAC Guideline and the risk-based capital ratios described in the CAR Guideline.

The risk-based Solo TLAC ratio will be the primary basis used by OSFI to assess the sufficiency of TLAC that is readily available to the domestic parent D-SIB and to assess the parent’s ability to act as a source of strength for its subsidiaries and/or other affiliates.

D-SIBs are required to apply this guideline beginning on November 1, 2023.

I. Overview

  1. The objective of this framework is to measure the sufficiency of loss absorbing capacity that is readily available to a domestic parent bank on a standalone, or solo, legal entity basis and to assess the parent’s ability to act as a source of strength for its subsidiaries and/or other affiliates. An appropriate amount of loss absorbing capacity should be readily available to the parent bank in times of stress. Under such circumstances, banking groups are better positioned to recover from stress and to be resolved in a manner that protects depositors, policyholders, and senior creditors while contributing to financial stability.

II. Scope of application

  1. The Solo TLAC guideline applies to all banks designated by the Superintendent as domestically systemically important banks (D-SIBs) pursuant to subsection 484.1(1) of the Bank Act. The domestic parent bank is the Canadian legal entity incorporated or continued under the Bank Act that is both an operating entity and the ultimate parent of the consolidated banking group.

III. Calculation of Solo TLAC

  1. The Solo TLAC ratio is calculated by dividing Solo TLAC Available by the Parental Risk-Weighted Assets (RWA) with this ratio expressed as a percentage:

    Solo TLAC ratio = Solo TLAC Available Parental Risk-Weighted Assets

IV. Minimum Solo TLAC ratio

  1. D-SIBs must maintain a minimum Solo TLAC ratio of 21.5%Footnote 1. D-SIBs are expected to meet the minimum TLAC requirements on a continuous basis.

V. Solo TLAC available (numerator)

  1. The numerator of the Solo TLAC ratio is the TLAC Measure of the institution as calculated by the D-SIB on a group consolidated basis under OSFI’s TLAC Guideline, subject to the following adjustments.

A. Common sharesFootnote 2 issued by consolidated subsidiaries to third party investors (i.e. minority interest/non-controlling interests)
  1. D-SIBs should fully deduct any common shares issued by consolidated subsidiaries to third parties that qualify as capital pursuant to section of the CAR Guideline.

B. Foreign regulatedFootnote 3 subsidiaries that are outside the scope of consolidation for regulatory capital purposesFootnote 4
  1. Deductions from capital of investments in foreign regulated subsidiaries that are outside the scope of consolidation and thatare regulated by an authority other than OSFI, including insurance subsidiaries, made pursuant to section 2.3 of the CAR Guideline should be reversed and subject to the treatment described in paragraph 12 of this Guideline.

C. Vested assets in foreign branchesFootnote 5
  1. For each foreign branch, D-SIBs should deduct vested assets in excess of the branch’s third-party liabilities. Vested assets are assets that cannot be accessed without regulatory approval (e.g. deposits in trust, capital equivalency deposits, asset maintenance requirements, etc.). Third-party liabilities of a branch are those liabilities of the branch that arise from obligations to third parties (i.e., liabilities that are not eliminated upon consolidation).

D. Non-regulated subsidiaries
  1. Institutions should deduct any amount of capital, TLAC, or equivalent in an non-regulated subsidiary that is required to be maintained for non-regulatory purposes (e.g. capital needed to meet a thin capitalization requirement under tax laws or to fulfil a third party net worth covenant).

VI. Parental Risk-Weighted Assets (RWAs) (denominator)

  1. The denominator of the Solo TLAC ratio uses total RWAs of the consolidated group as calculated by the D-SIB under OSFI’s CAR Guideline, subject to the following adjustments:

A. Subsidiaries and branches regulated by a foreign authority that are consolidated for regulatory purposes
  1. For each foreign-regulated subsidiaryFootnote 6 and foreign branch, D-SIBs should first deduct the RWAs attributable to the subsidiary or branch from the group consolidated RWAs as calculated under the CAR Guideline. RWAs attributable to foreign-regulated subsidiaries and foreign branches are calculated by applying the CAR Guideline on a stand-alone basis to each subsidiary or branch and excluding any capital requirements associated with exposures that are eliminated upon the subsidiary’s and branch’s consolidation for accounting purposes. For clarity, the same measurement basisFootnote 7 (e.g. the Standardized approach or the Internal Ratings Based approach), as well as the factors or inputs (e.g., probabilities of default (PD), loss-given default (LGD), exposure-at-default (EAD)) used to calculate consolidated capital requirements under the CAR Guideline should also be used to calculate the RWAs associated with any foreign-regulated subsidiaries and branches for Solo TLAC purposes.

  2. Institutions must then calculate revised RWAs for each foreign-regulated subsidiary by multiplying the parent D-SIB’s exposure to the subsidiary by 325%. The exposureFootnote 8 is the sum of the following items:

    1. The value of the parent’s investment in the subsidiary computed using the equity method of accounting as per International Financial Reporting Standards (IFRS);

    2. Subordinated debt and other capital elements issued by the subsidiary to the parent;

    3. Senior debt or claims recognized as internal TLAC, internal Minimum Requirements for Own Funds and Eligible Liabilities (MREL) or equivalent issued by the subsidiary to the parent; and

    4. The amount that the parent D-SIB could be required to pay out under capital guarantees provided to the subsidiary as described under paragraph 16.

  3. Institutions must calculate revised RWAs for foreign branches by multiplying the D-SIB’s exposure to its branches by 300%. The exposure is calculated as the difference between the following items:

    1. a. Total Assets, net of deductions already applied to the TLAC Measure pursuant to the CAR Guideline or the TLAC Guideline and all other assets arising from intra-group transactionsFootnote 9, across all foreign branches. Total Assets refers to the aggregate assets reported on the stand-alone balance sheet of the branch; and

    2. Total Third-party liabilities across all foreign branches. Third-party liabilities refer to those liabilities that are not eliminated upon accounting consolidation.

  4. Where the calculation under paragraph 13 results in a negative value, institutions should adjust the value of the exposure by adding amounts remitted to the Canadian branch net of amounts transferred by the Canadian branch to its foreign branches, across all of the D-SIB’s foreign branches. The resulting adjustment must not exceed the absolute value of the amount determined under paragraph 13.

    Institutions should apply the 300% risk-weight to the absolute value of the exposure resulting from the above adjustments.

B. Foreign regulated subsidiaries that are outside the scope of consolidation for regulatory purposes
  1. RWAs arising from investments in foreign regulated subsidiaries, including insurance subsidiaries, that are de-consolidated for regulatory capital purposes, which are risk weighted pursuant to section 2.3 of the CAR Guideline and included in group consolidated RWAs under the CAR Guideline should be reversed and are subject to the treatment described under paragraph 12 of this Guideline.

C. Parental guarantees
  1. Capital guaranteesFootnote 10 can either directly guarantee issuances of capital instruments (e.g., subordinated debt, preferred shares, or common shares) by subsidiaries to third-parties, or they can be structured in the form of a capital maintenance agreement (CMA), formalizing the actions or intentions the parent will take to maintain the subsidiary’s capital at or above a certain level. Capital guarantees provided by the parent D-SIB to its subsidiaries are treated as a direct capital investment under this guideline. The amount that should be used for the exposure in paragraph 12(d) for CMA is equal to the minimum amount of capital that is required to be invested under the CMA assuming the subsidiary is holding zero capital and, for a capital instrument guarantee, it is equal to the maximum amount that is payable under the guarantee.

  2. Non-capital guarantees consist of guarantees that provide any form of indemnification to third partiesFootnote 11 and that are not included in the definition of capital guarantees under paragraph 16. Exposures to non-capital guarantees should be converted into credit exposure equivalent amounts using a credit conversion factor (CCF) of 100%. The exposure is defined as the outstanding exposure of the parent bank under the guaranteeFootnote 12. In the case of lines of credit and letters of credit, the undrawn amount of the exposure would be multiplied by 100%. The drawn portion of a line of credit is not subject to any requirements.

  3. The credit exposure equivalent amounts calculated under paragraph 17 should be risk weighted using the long-term credit rating of the subsidiaryaccording to Table 1. The long-term credit ratings used in the determination of the applicable risk weight must be the stand-alone external credit rating of the subsidiary, excluding any uplift due to parental support. These ratings will be otherwise subject to the same requirements as specified in section 4.2 of the CAR Guideline.

  5. Institutions must apply a 100% risk weight to the credit exposure equivalent of a non-capital guarantee for any subsidiary for which it is not possible to infer a rating under section 4.1.4 of the CAR Guideline.

  6. Guarantees provided to OSFI-regulated subsidiaries and provincially regulated subsidiaries are excluded from the calculation of parental RWAs.

  7. Undrawn lines of credit whose cancellation is not subject to specific conditions or notice periods or that are unconditionally cancellable at any time (e.g. without a required notice period) may be excluded from the computation of parental RWAs.

  8. In the case of a non-capital guarantee where the exposure guaranteed is an obligation of a subsidiary arising from a collateralized securities lending (borrowing) agreement (or obligations arising from repo-style transactions) with a third party, institutions can recognize the collateral provided by the subsidiary to the third party to calculate the amount covered under the guarantee. In these cases, an institution can use the Comprehensive Approach defined in Chapter 4 of the CAR Guideline to determine its exposure amount.
