From the report:
1044. Because anticipated exportation "alone is not proof that the granting of the subsidy is tied tothe anticipation of exportation"2342, the legal standard for de facto export contingency under Article 3.1(a) and footnote 4 of the SCM Agreement further requires that there exists a relationship of conditionality between the granting of the subsidy and anticipated exportation. Where a subsidy is alleged to be "in fact tied to … anticipated exportation", the relationship of conditionality is, unlike in the case of de jure export contingency, not expressly or by necessary implication provided in the terms of the relevant legal instrument granting the subsidy. Under such circumstances, we consider that the factual equivalent of such conditionality can be established by recourse to the following test: is the granting of the subsidy geared to induce the promotion of future export performance by the recipient?
...
1046. The existence of de facto export contingency, as set out above, "must be inferred from the total configuration of the facts constituting and surrounding the granting of the subsidy"2343, which may include the following factors: (i) the design and structure of the measure granting the subsidy; (ii) the modalities of operation set out in such a measure; and (iii) the relevant factual circumstances surrounding the granting of the subsidy that provide the context for understanding the measure's design, structure, and modalities of operation.
1047. Moreover, where relevant evidence exists, the assessment could be based on a comparison between, on the one hand, the ratio of anticipated export and domestic sales of the subsidized product that would come about in consequence of the granting of the subsidy, and, on the other hand, the situation in the absence of the subsidy. The situation in the absence of the subsidy may be understood on the basis of historical sales of the same product by the recipient in the domestic and export markets before the subsidy was granted. In the event that there are no historical data untainted by the subsidy, or the subsidized product is a new product for which no historical data exists, the comparison could be made with the performance that a profit-maximizing firm would hypothetically be expected to achieve in the export and domestic markets in the absence of the subsidy. Where the evidence shows, all other things being equal, that the granting of the subsidy provides an incentive to skew anticipated sales towards exports, in comparison with the historical performance of the recipient or the hypothetical performance of a profit-maximizing firm in the absence of the subsidy, this would be an indication that the granting of the subsidy is in fact tied to anticipated exportation within the meaning of Article 3.1(a) and footnote 4 of the SCM Agreement.
1048. The following numerical examples illustrate when the granting of a subsidy may, or may not, be geared to induce promotion of future export performance by a recipient. Assume that a subsidy is designed to allow a recipient to increase its future production by five units. Assume further that the existing ratio of the recipient's export sales to domestic sales, at the time the subsidy is granted, is 2:3. The granting of the subsidy will not be tied to anticipated exportation if, all other things being equal, the anticipated ratio of export sales to domestic sales is not greater than the existing ratio. In other words, if, under the measure granting the subsidy, the recipient would not be expected to export more than two of the additional five units to be produced, then this is indicative of the absence of a tie. By contrast, the granting of the subsidy would be tied to anticipated exportation if, all other things equal, the recipient is expected to export at least three of the five additional units to be produced. In other words, the subsidy is designed in such a way that it is expected to skew the recipient's future sales in favour of export sales, even though the recipient may also be expected to increase its domestic sales.
So the key to determining whether there is de facto export contingency is: whether "the granting of the subsidy provides an incentive to skew anticipated sales towards exports, in comparison with the historical performance of the recipient or the hypothetical performance of a profit-maximizing firm in the absence of the subsidy, ..."
I talked about an "incentive to export" standard here. Let me just say that after a first reading, I'm impressed by the clarity of the Appellate Body's reasoning, but perhaps in part that is because I agree with it!
