StandardisedApproach –

The standardised approach for calculating operational RWA.

FCCalculator

Calculator for the Financial Component (FC).

Methods:

compute –

Compute the Financial Component (FC).

compute `staticmethod`

compute(
    bank: Bank,
    date: date,
    scenario_manager: ScenarioManager,
) -> float

Compute the Financial Component (FC).

FC is the sum of the following two: 1. 3yr_avg(abs(net P&L trading book)) 1. 3yr_avg(abs(net P&L banking book))

ILDCCalculator

Calculator for the Interest, Leases, and Dividend Component (ILDC).

Methods:

compute –

Compute the Interest, Leases, and Dividend Component (ILDC).

compute `staticmethod`

compute(
    bank: Bank,
    date: date,
    scenario_manager: ScenarioManager,
) -> float

Compute the Interest, Leases, and Dividend Component (ILDC).

ILDC is the sum of the following two: 1. the minimum of - 3yr_avg(abs(interest income - interest expense)) - 3yr_avg(interest earning assets) * 2.25% 2. 3yr_avg(dividend income)

LCCalculator

Calculator for the Loss Component (LC).

Methods:

compute –

Compute the Loss Component (LC).

compute `staticmethod`

compute(
    bank: Bank,
    date: date,
    scenario_manager: ScenarioManager,
) -> float

Compute the Loss Component (LC).

LC is equal to 15 times average annual operational risk losses incurred over the previous 10 years

SCCalculator

Calculator for the Services Component (SC).

Methods:

compute –

Compute the Services Component (SC).

compute `staticmethod`

compute(
    bank: Bank,
    date: date,
    scenario_manager: ScenarioManager,
) -> float

Compute the Services Component (SC).

SC is the sum of the following two: 1. the maximum of - 3yr_avg(other operating income) - 3yr_avg(other operating expense) 2. the maximum of - 3yr_avg(fee income) - 3yr_avg(fee expense)
