GBL (Government Bill of Lading)
An ancient principle of equity, recognized by maritime nations, pre-dating the concept of insurance and still valid today, in which all parties involved in a sea adventure (vessel, cargo, and freight) proportionately share losses resulting from a voluntary and successful effort to save the entire venture from an imminent peril. There are two types of General Average acts:
1. Voluntary Sacrifice of a part of the vessel or a part of the cargo, e.g. jettison of property to stabilize the vessel during heavy weather.
2. Extraordinary Expense necessarily incurred for the joint benefit of vessel and cargo, e.g. towing charges incurred to assist a disabled vessel to a port of refuge.
General Average Adjuster - See "Average Adjuster."
A guarantee by the owner of the cargo (usually the consignee) to pay that proportion of the general average contribution, salvage, or special charges owed by the shipment, and to give information about its value so an Average Adjustment can be prepared. The vessel owner will not release cargo for delivery to the consignee until the cargo owner signs this average agreement or bond, which is prepared by the general average adjuster.
General Average Bond - See "General Average Agreement."
General Average Deposit
A cash deposit (usually based on the estimated percentage of General Average) which the General Average Adjuster demands from the owner of the cargo to secure the payment of its proportion of the General Average. This cash deposit is usually demanded as additional security to the General Average Bond. The deposit may be replaced by a General Average Guarantee.
General Average Expenditures - See "General Average."
General Average Guarantee
An insurance company's written guarantee to the General Average Adjuster guaranteeing to pay the legally due proportion of General Average finally assessed against the Assured’s insured cargo. This guarantee is usually accepted by the Adjuster in lieu of a cash deposit and is additional security to the bond signed by the owner of the goods.
General Average Sacrifice - See "General Average."
Documents presented by cargo owners to a General Average Adjuster to replace the vessel owner's maritime lien on cargo for its share of General Average and to obtain release of cargo from the steamship company.
