Multiline Insurance

What Does Multiline Insurance Mean?
An insurance instrument used to bundle the risk exposures of multiple insurance obligations into one insurance contract. The risk exposures put together often are related, such as property and casualty risks.

Investopedia explains Multiline Insurance
Many different varieties of multiline contracts exist, and they cover a wide range of risk exposures. The basis behind multiline contracts is that a firm often is exposed to a portfolio of risk, and instead of creating a portfolio of insurance policies to manage that risk, they should use a single multiline contract to manage the portfolio of risks. One insurance contract is then more efficient and less costly than many contracts.
