(banking) Payment of a bill of exchange, which is the responsibility of the drawee, can be either completely or partially guaranteed via an aval (joint and several guarantee), where the guarantor places his/her signature on the draft either alone or with corresponding explanation "per aval" or "as guarantor." If other information is lacking, the guarantor commits him/herself on behalf of the issuer. See bill of exchange.
average

(a) A particular average is an insurance loss that affects specific interests only.
(b) A general average is an insurance loss that affects all cargo interests on board the vessel as well as the ship herself.
See also particular average; general average; with average; free of particular average; deductible average.
