(2) All data, economic analyses, and other information relied on to justify the workshare discount; and

(3) A certification based on comprehensive, competent analyses that the discount will not adversely affect either the rates or the service levels of users of postal services who do not take advantage of the workshare discount.

(i) Whenever the Postal Service establishes a new discount or surcharge rate it does not view as creating a workshare discount, it must include with its filing:

(1) An explanation of the basis for its view that the discount or surcharge rate is not a workshare discount; and

(2) A certification that the Postal Service applied accepted analytical principles to the discount or surcharge rate.

(j) Whenever the Postal Service includes a rate incentive with its planned rate adjustment, it must include with its filing:

(1) Whether the rate incentive is being treated under § 3030.128(f)(2) or under § 3030.128(f)(1) and (g);

(2) If the Postal Service seeks to include the rate incentive in the calculation of the percentage change in rates under § 3030.128(f)(2), whether the rate incentive is available to all mailers equally on the same terms and conditions; and

(3) If the Postal Service seeks to include the rate incentive in the calculation of the percentage change in rates under § 3030.128(f)(2), sufficient information to demonstrate that the rate incentive is a rate of general applicability, which at a minimum includes: The terms and conditions of the rate incentive; the factors that determine eligibility for the rate incentive; a statement that affirms that the rate incentive will not benefit a single mailer; and a statement that affirms that the rate incentive is not only available upon the written agreement of both the Postal Service and a mailer, or group of mailers, or a foreign postal operator.

(k) For each class or product where the attributable cost for that class or product exceeded the revenue from that class or product as determined by the Commission, a demonstration that the planned rate adjustments comply with the requirements in subpart G of this part.
