**What is Operational Risk?**

Operational risk is defined as the risk of loss resulting from inadequate or failed internal processes, people and systems or from external events. It includes events such as fraud, employee errors, criminal activity, and security breaches. However, this definition **excludes** **reputational risk** as well as **strategic risk**.

Following the announcement of Basel III reforms, operational risk should be measured using the **standardized approach** in internationally active banks, and supervisors still have the discretion to apply the standardized approach among non-internationally active lenders.

**Components of the Standardized Approach for Measurement of Operational Risk**

The minimum operational risk capital for a bank is given by:

**ORC = BIC × ILM**

**Business Indicator Component (BIC)**

The Business Indicator Component (BIC) is a product of the Business Indicator (BI) and a set of regulatory marginal coefficients \( { a }_{ i } \).

$$ \left( BIC \right) =\sum { \left( { a }_{ i }\times { BI }_{ i } \right) } $$

The BI consists of select items from a bank’s financial statements that are representative of the bank’s operational risk exposure. In particular, the BI has 3 components:

- The interest, leases and dividends component (ILDC)
- The services component (SC), and
- The financial component, FC

**Important**: all the three components must be calculated as averages over **3** years.

The BIs of large international banks are typically large figures running into billions of Euros – the chosen denomination for operational risk capital calculations. A bank’s BI tells a lot about its operational risk exposure. For this reason, the standardized approach divides banks into 3 buckets according to the size of their BI. Each bucket is associated with a regulatory determined coefficient \( { a }_{ i } \).** **As the BI increases, so do the coefficients. A summary is set out in the table below:

BI Bucket |
1 | 2 | 3 |

BI range |
≤ €1bn | €1bn < BI ≤ €30bn | ≥€30bn |

Marginal BI coefficient, \( { a }_{ i } \) |
0.12 | 0.15 | 0.18 |

** **

**Example 1: Calculating the BIC of a bank with a BI of €40bn**

BI Bucket | 1 | 2 | 3 |

BI range | ≤ €1bn | €1bn < BI ≤ €30bn | ≥€30bn |

Marginal BI coefficient, \( { a }_{ i } \) | 0.12 | 0.15 | 0.18 |

BI of €40bn
BIC = sum of buckets 1-3 = €4.65bn. |
€1bn × 12% = €0.12bn |
€(30 – 1) × 15% = €4.35bn |
€(40 – 30) × 18% = €0.18bn |

** **

**Example 2: Calculating the BIC of a bank with a BI of €25bn**

BI Bucket | 1 | 2 | 3 |

BI range | ≤ €1bn | €1bn < BI ≤ €30bn | ≥€30bn |

Marginal BI coefficient, \( { a }_{ i } \) | 0.12 | 0.15 | 0.18 |

BI of €25bn
BIC = sum of buckets 1-3 = €3.72bn. |
€1bn × 12% = €0.12bn |
€(25 – 1) × 15% = €3.6bn |

Internal Loss Multiplier

Internal Loss Multiplier

The internal Loss Multiplier is defined as:

$$ ILM=\ln { \left[ exp\left( 1 \right) -1+{ \left( \frac { LC }{ BIC } \right) }^{ 0.8 } \right] } $$

As can be seen from the equation above, the ILM (the Internal Loss Multiplier) is a function of the BIC and the Loss Component (LC), where the latter is equal to **15 **times a bank’s average historical losses over the preceding 10 years. Firms with then less than 10 years of data must use a minimum of 5 years data while computing the average historical loss.

**Important**:

- When LC = BIC, the ILM factor is equal to 1 and in effect, it becomes the default ILM level in certain circumstances.
- When the LC is greater than the BIC, the ILM is greater than one.
- When the LC is less than the BIC, the ILM is less than one.
- For firms with BI levels less than €1bn, the ILM is set to 1, and therefore internal loss data does not affect the capital calculation.
- Under transitional arrangements, banks without 5-year historical data must set the ILM to 1, although the supervisor in charge maintains the discretion to set higher levels.

**How is the Standardized Measurement Approach (SMA) Different from the Advanced Measurement Approach (AMA)?**

The AMA, introduced in Basel II, allows for the estimation of regulatory capital to be based on a diverse range of internal modelling practices conditional on supervisory approval. The method has had a significant degree of flexibility, meaning that banks have been at liberty to use slightly different models while calculating capital required. It is this flexibility that has resulted in the AMA being replaced since it has resulted in widely incomparable internal modeling practices that have exacerbated variability in risk-weighted asset calculations and eroded confidence in risk-weighted capital ratios. The SMA has limited flexibility and requires banks to follow precise guidelines in the entire capital calculation process.

**General Criteria Recommended by the Basel Committee for the Identification, Collection, and Treatment of Operational Loss Data**

To use the Loss Component (LC), banks have to observe certain guidelines:

- A bank must have quality loss data spanning a 10-year period. Under transitional arrangements, banks are allowed to use a minimum of 5 years of loss data.
- A bank must have documented procedures and processes for the identification, collection and treatment of internal loss data.
- The bank must be ready to map internal loss data onto the relevant Level 1 supervisory categories as defined in Annex 9 of the Basel II Framework, on request (by the supervisor).
- The data must capture all material events and exposures from all geographical locations and subsystems. Any loss event of €20,000 or more is considered material.
- The bank must keep records of specific dates when operational risk events occurred or commenced.
- Operational loss events related to credit risk and that are accounted for in credit risk RWAs should not be included in the loss data set.
- For the purpose of calculating minimum regulatory capital under the SMA framework, operational risk losses related to market risk are treated as operational risks.
- The bank must have an independent mechanism to validate and ensure accuracy of the data.

**Specific Criteria on Loss Data Identification, Collection, and Treatment**

- The bank must put in place policies that address various aspects of internal loss data, including collection dates, gross loss definition, and grouping of losses.
- Gross loss is a loss before recoveries of any type. Net loss is defined as the loss after taking into account the impact of recoveries.
- Banks must be able to identify gross operational losses and recoveries for all operational risk events.
- Items included in gross loss calculations:
- Direct charges, including impairments and settlements
- External expenses linked to an operational risk event, e.g., legal expenses
- Provisions or reserves accounted for in the P&L against the potential operational loss impact
- Material “timing losses” resulting from operational risk events impacting the cash flows or financial statements of previous financial accounting periods.
- Temporary losses booked in suspense accounts but not recorded in P&L
- Items excluded from gross calculations:
- General maintenance costs
- Internal or external business enhancement costs incurred following a risk event
- Insurance premiums
