Also: non-interest business. Transactions conducted by the bank which are not reported in the balance sheet. Under Swiss law these include contingent liabilities (e.g. guarantees), irrevocable commitments, liabilities for calls on shares, commitment facilities, open derivatives contracts and fiduciary transactions. These transactions must be reported separately below the line and underpinned by equity capital. Bank services such as investment counselling, asset management, securities trading and payments also fall under off-balance-sheet operations.
