This chapter sets out rules and guidance for large exposures and the concentration risk capital component (the CNCOM), implementing the large exposures requirements of articles 66(3) (in part) and 106 to 117 and paragraph 7 of Annex V of the Banking Consolidation Directive and articles 28 to 32 and Annex VI of the Capital Adequacy Directive.
A large exposure may be in the form of a loan to a single borrower, or it may arise across many transactions involving different types of financial instruments with several counterparties within the same group of companies. Where a firm's exposure to its counterparty is large, it risks a large loss should the counterparty default. Such a loss may be sufficient on its own to threaten the solvency of the firm.
