All banks must report immediately to the CBB any material losses as soon as the bank becomes aware of them. This notification requirement is separate from notifications for loan write-offs (see BR-5.2.3) or frauds (see above), but refers to losses caused by external events (e.g. falls in stock markets) or internal control failures. In this context 'material' would mean: a loss which exceeds 5% of net earnings in a given quarter; or a loss which reduces the bank's capital adequacy by more than 1%; or a loss which reduces total assets by more than 1%.
