What does underwrite mean?
Underwrite means to take responsibility for a financial risk or to provide financial backing for an arrangement. An insurer may underwrite a policy by agreeing to pay specified losses, while a bank or group of investors may underwrite a loan or share issue by supplying the promised funds. The word therefore carries a sense of standing behind something with money and accepting the consequences if it fails. It is especially associated with insurance but is also used in banking, corporate finance, publishing, and government policy. Underwriting is typically a formal, deliberate act rather than casual or emotional support. Although the term can sound technical, its central idea is simple: one party assumes defined financial risk so that another party can proceed with greater confidence. The word is also useful outside finance in expressions such as "underwrite a project," where support may be financial, institutional, or organizational.
verbTo assume financial responsibility for an asset, transaction, or risk, especially by agreeing to pay covered losses or provide financial backing.
- To insure or guarantee a risk, transaction, or asset by agreeing to provide financial backing or pay covered losses.
- Historically, to write beneath another text or signature, or to place one's name beneath a document.
