"Article 77 adopts the same principle as Article 88 ULIS, but clarifies certain matters. First of all, it makes clear that the aggrieved party’s duty to mitigate loss includes not only loss of assets (damnum emergens) but also loss of profit (lucrum cessans). The phrase ‘loss resulting from the breach’ appears in the English versions of both the CISG and ULIS. However, a change in the wording of the French versions (‘la perte . . . resultant de la contravention) (CISG) instead of (‘la perte subie) (ULIS) is intended to indicate that the aggrieved party is obliged not only to take reasonable measures to mitigate loss which has already occurred, but also to counteract imminent loss. Article 77, second sentence, clearly lays down that damages cannot be claimed in respect of loss which could have been mitigated by the aggrieved party, while Article 88 ULIS leaves open the extent to which damages are to be reduced in the event of a failure to observe the requirement to mitigate loss. . . ."
