39 CFR 3015.7 - Standards for compliance.
For purposes of determining competitive products' compliance with 39 U.S.C. 3633, the Commission will apply the following standards:
(a) Incremental costs will be used to test for cross-subsidies by market dominant products of competitive products. To the extent that incremental cost data are unavailable, the Commission will use competitive products' attributable costs supplemented to include causally related, group-specific costs to test for cross-subsidies.
(b) Each competitive product must recover its attributable costs as defined in 39 U.S.C. 3631(b).
(c) Annually, on a fiscal year basis, the appropriate share of institutional costs to be recovered from competitive products collectively is, at a minimum, 5.5 percent of the Postal Service's total institutional costs.
