Which type of revenue growth occurs when new coverage is added to an existing account or new lines of coverage are introduced?

The type of revenue growth described occurs when additional coverage is added to an existing account or when new lines of coverage are introduced. This process enhances the overall revenue from existing clients by expanding the range of services provided.

In this context, account rounding revenue growth is the correct choice because it specifically refers to maximizing the value of an existing customer relationship by offering additional coverages. This approach not only solidifies the client relationship but also increases the average premium per client, contributing to overall revenue growth from existing accounts. The aim is to 'round out' the client's coverage to ensure comprehensive protection across various risks, which can also lead to client retention and satisfaction.

New coverage and lines of coverage are strategic moves within existing accounts, making it distinct from other forms of growth, such as organic revenue growth, which typically involves expanding client options without necessarily deepening existing relationships.
