This chapter contains supporting information on the definition of indirect and synthetic holdings, the calculation of minority interests and the application of transitional arrangements.
A banking group consists of two legal entities that are both banks. Bank P is the parent and Bank S is the subsidiary and their unconsolidated balance sheets are set out below.

The balance sheet of Bank P shows that in addition to its loans to customers, it owns 70% of the common shares of Bank S, 80% of the Additional Tier 1 of Bank S and 25% of the Tier 2 capital of Bank S. The ownership of the capital of Bank S is therefore as follows:

For illustrative purposes Bank S is assumed to have risk-weighted assets of 100. In this example, the minimum capital requirements of Bank S and the subsidiary’s contribution to the consolidated requirements are the same since Bank S does not have any loans to Bank P. This means that it is subject to the following minimum plus capital conservation buffer requirements and has the following surplus capital:
| Minimum and surplus capital of Bank S | ||
|
| Minimum plus capital conservation buffer | Surplus |
| Common Equity Tier 1 | 7.0 (= 7.0% of 100) | 3.0 (=10 – 7.0) |
| Tier 1 | 8.5 (= 8.5% of 100) | 6.5 (=10 + 5 – 8.5) |
| Total capital | 10.5 (= 10.5% of 100) | 12.5 (=10 + 5 + 8 – 10.5) |
The following table illustrates how to calculate the amount of capital issued by Bank S to include in consolidated capital, following the calculation procedure set out in CAP10.20 to CAP10.26:
| Bank S: amount of capital issued to third parties included in consolidated capital | |||||
|
| Total amount issued (a) | Amount issued to third parties (b) | Surplus (c) | Surplus attributable to third parties (ie amount excluded from consolidated capital) (d) =(c) * (b)/(a) | Amount included in consolidated capital (e) = (b) – (d) |
| Common Equity Tier 1 | 10 | 3 | 3.0 | 0.90 | 2.10 |
| Tier 1 | 15 | 4 | 6.5 | 1.73 | 2.27 |
| Total capital | 23 | 10 | 12.5 | 5.43 | 4.57 |
The following table summarises the components of capital for the consolidated group based on the amounts calculated in the table above. Additional Tier 1 is calculated as the difference between Common Equity Tier 1 and Tier 1 and Tier 2 is the difference between Total Capital and Tier 1.
|
| Total amount issued by parent (all of which is to be included in consolidated capital) | Amount issued by subsidiaries to third parties to be included in consolidated capital | Total amount issued by parent and subsidiary to be included in consolidated capital |
| Common Equity Tier 1 | 26 | 2.10 | 28.10 |
| Additional Tier 1 | 7 | 0.17 | 7.17 |
| Tier 1 | 33 | 2.27 | 35.27 |
| Tier 2 | 10 | 2.30 | 12.30 |
| Total capital | 43 | 4.57 | 47.57 |
CAP30.18 to CAP30.31 describes the regulatory adjustments applied to a bank’s investments in its own capital or other total loss-absorbing capacity (TLAC) instruments or those of other financial entities, even if they do not have direct holdings. More specifically, these paragraphs require banks to capture the loss that a bank would suffer if the capital or TLAC instrument is permanently written off, and subject this potential loss to the same treatment as a direct exposure. This section defines indirect and synthetic holdings and provides examples.
An indirect holding arises when a bank invests in an unconsolidated intermediate entity that has an exposure to the capital of an unconsolidated bank, financial or insurance entity and thus gains an exposure to the capital of that financial institution.
A synthetic holding arises when a bank invests in an instrument where the value of the instrument is directly linked to the value of the capital of an unconsolidated bank, financial or insurance entity.
Set out below are some examples of indirect and synthetic holdings to help illustrate this treatment:
| FAQ1 | What would be the prudential treatment applicable to a financial instrument where a bank commits itself to buy newly issued shares of an insurance company for a given amount should certain events occur? For example, consider the following case. Bank A enters into a contract with Firm B (an insurance company). The contract stipulates that, if any of the three events defined below occurs within the next three years, Bank A must buy for €10 million new shares of Firm B (leading to a capital increase for Firm B). The new shares are generally issued with a discount (eg 5%) on the average market price recorded on the trading days following the event. In such a case, Bank A has to provide the cash to Firm B within a predefined timeline (eg 10 days). Event 1: Firm B incurs a technical loss above a threshold (eg €1m) for a specific event (eg natural catastrophe). Event 2: The loss ratio of a given line of business is higher than 120% for two consecutive semesters. Event 3: The share price of Firm B falls below a given value. Bank A is not allowed to sell the financial instrument resulting from this contract to other entities. CAP30.18 to CAP30.31 provide that investments in the capital of banking, financial and insurance entities include direct, indirect and synthetic holdings of capital instruments. These instruments must be deducted following a corresponding deduction approach (potentially with the application of a threshold). CAP99.8 to CAP99.12 defines indirect and synthetic holdings and provides examples. The transaction described above has to be regarded as a derivative instrument (in this case, a put option) that has a capital instrument (a share) of a financial sector entity as its underlying. Hence, it should be regarded as a synthetic holding to be deducted from Common Equity Tier 1 as per the applicable deduction rules. |
In all cases, the loss that the bank would suffer on the exposures if the capital of the financial institution is permanently written-off is to be treated as a direct exposure (ie subject to a deduction treatment).
The flowchart below illustrates the application of transitional arrangements in CAP90.4, which also sets out the "three conditions" and "phase-out" arrangements.

This standard describes the scope of application of the Basel Framework.
This standard describes the criteria that bank capital instruments must meet to be eligible to satisfy the Basel capital requirements, as well as necessary regulatory adjustments and transitional arrangements.
This standard describes the framework for risk-based capital requirements.
This standard describes how to calculate capital requirements for credit risk.
This standard describes how to calculate capital requirements for market risk and credit valuation adjustment risk.
This standard describes how to calculate capital requirements for operational risk.
This standard describes the simple, transparent, non-risk-based leverage ratio. This measure intends to restrict the build-up of leverage in the banking sector and reinforce the risk-based requirements with a simple, non-risk-based "backstop" measure.
This standard describes the Liquidity Coverage Ratio, a measure which promotes the short-term resilience of a bank's liquidity risk profile.
The net stable funding ratio requires banks to maintain a stable funding profile in relation to the composition of their assets and off-balance-sheet activities.
Large exposures regulation limits the maximum loss that a bank could face in the event of a sudden counterparty failure to a level that does not endanger the bank's solvency. This standard requires banks to measure their exposures to a single counterparty or a group of connected counterparties and limit the size of large exposures in relation to their capital.
This standard establishes minimum standards for margin requirements for non-centrally cleared derivatives. Such requirements reduce systemic risk with respect to non-standardised derivatives by reducing contagion and spillover risks and promoting central clearing.
The Pillar 2 supervisory review process ensures that banks have adequate capital and liquidity to support all the risks in their business, especially with respect to risks not fully captured by the Pillar 1 process, and encourages good risk management.
This standard sets out disclosure requirements, which aim to encourage market discipline.
The Basel Core Principles provide a comprehensive standard for establishing a sound foundation for the regulation, supervision, governance and risk management of the banking sector.
