Concentrations / Portfolio Management

A concentration of credit consists of direct, indirect, or contingent obligations exceeding 25 percent of a bank's capital structure. In general concentrations may involve one borrower, an affiliated group of borrowers, or borrowers engaged in or dependent on one industry.

A bank's loan portfolio is typically its largest asset and predominate source of revenue. Consequently, it is also one of the greatest sources of risk, making effective portfolio management a key factor in bank safety and soundness.
