Which characteristic does NOT describe the surplus lines market?

The surplus lines market is characterized by its ability to provide coverage for risks that are not typically offered by standard insurance companies. This market is known for its flexibility and responsiveness to unique or high-risk situations.

The term "standardized" does not fit the description of the surplus lines market because it generally caters to non-conventional risks that standard carriers might decline. Unlike standard insurance products that follow predefined guidelines and offer similar coverage options, surplus lines policies are often custom-tailored to meet the specific needs of the insured, which makes them less standardized.

In contrast, characteristics such as "unusual," "large," and "difficult to place" accurately describe the surplus lines market, as it is designed to handle unique, high-value, or complex risks that are typically hard to find coverage for through standard markets.
