The calculation of total exposure for the leverage ratio must generally follow the accounting measures of exposures (i.e. as reported in the financial statements of the Bahraini Islamic bank licensees). All the on-balance sheet, non-derivative exposures must be included net of specific provisions and valuation adjustments (e.g. credit valuation adjustments). The impact of credit risk mitigation (including physical or financial collateral, guarantees, Urbun, Hamish Jiddiyah, etc.) must not be considered, and on-balance sheet exposures must not be adjusted for the purpose of calculating the total exposure (i.e. they must be unweighted). Netting of financing exposures against investment accounts/deposits is not allowed. Specific details on the treatment of on and off-balance sheet items in the calculation of total exposure are provided in this Section.
