Calculation of reduction in value of cargo insured under valued policies following insured damage. The gross sound and damaged values are compared to find the percentage reduction in value to be applied to the agreed value to give the amount of the claim. Where percentages cannot be agreed the damaged goods are sold. The difference between the sound value and the sale price gives the relevant percentage. Total loss of part of the cargo is based on the proportion of the insurable value that the part lost bears to the insurable value as a whole.
