Which of the following is NOT a component of the CAMEL ratings used by regulators?

The CAMEL rating system is a framework used by financial regulators to evaluate the overall condition of financial institutions, primarily banks. The components of the CAMEL ratings include Capital Adequacy, Asset Quality, Management Quality, Earnings, and Liquidity.

While "Management Efficiency" might seem relevant, the term used in the CAMEL model is "Management Quality." This assesses how effectively management operates and controls the institution. Therefore, "Management Efficiency" is not a recognized component of the CAMEL framework. In summary, the focus on qualitative and quantitative aspects of management performance under the umbrella of Management Quality distinguishes it from the option specified, which uses a different terminology.
