Legal Definition
Reinsurance is a contract where an original insurance company (the ceding company) transfers a portion of its risk to another insurance company (the reinsurer). This mechanism allows the original insurer to manage its exposure by transferring some of its liabilities, thereby reducing its net capital requirement or risk exposure.
Plain-English Translation
Imagine you have a big insurance company that needs to protect itself from big losses. Reinsurance is like selling some of those protection duties to another insurance company. The original company agrees to pass some of its potential losses to the other company, which helps the original company stay financially stable and less risky.
