The Rule XVI was added at the 1877 Antwerp Conference, and for that reason was at one time called the Antwerp Rule. It stated simply: The value to be allowed for goods sacrificed shall be that value which the owner would have received if such goods had not been sacrificed. Between 1890 and 1974 the concept of market value at destination, or at the termination of the adventure, continued to govern both the calculation of the amount made good to cargo and its contributory value. The Rule was again amended at Hamburg in 1974 in consequence of the decision taken at that time to substitute invoice values for market values as the basis both for the amounts to be made good to cargo and its contributory value. No change to the Rule was made in 1994 and the only change made in 2004 was to apply paragraph numbering.
