Originally denoting a charge or customs duty payable by the owner of goods to be shipped, the term later denoted the financial liability from goods lost or damaged at sea, and specifically the equitable apportionment of this between the owners of the vessel and the cargo (late 16th cent.); this gave rise to the general sense of the equalizing out of gains and losses by calculating the mean (mid 18th cent.).
