It stands for name give-up; a practice where the identities of market participants (traders) are disclosed during post-trade processing (after a trade has been matched)- the time during which such parties intend to remain anonymous. This is meant to discourage buy-side participation and transactions that are all-to-all anonymous. The names/ identifies of the counterparties are revealed to each other after execution of a a trade (for example, a credit default swap (CDS) trade). In swap markets, this involves the disclosure (the disclosure caused to be made) of the identity of each swap counterparty to the other after a swap trade has been matched anonymously on an exchange or venue and forwarded for clearing (at a derivatives clearing organization).

Name give-up (NGU) is designed to enhance transparency and responsible trading practices in the market.

It is also known as a post-trade name give-up or a post-trade name disclosure.
