(a) Supporting technical documentation shall include the items specified in paragraphs (b) through (k) of this section, as applicable to the specific rate adjustment filing. This information must be supported by workpapers in which all calculations are shown and all relevant values ( e.g., rates, CPI-U values, billing determinants) are identified with citations to original sources. The information must be submitted in machine-readable, electronic format. Spreadsheet cells must be linked to underlying data sources or calculations (not hard-coded), as appropriate. (b) The maximum rate adjustment authority, by class, as summarized by § 3030.127 and calculated separately for each of subparts C through H of this part, as appropriate. (c) A schedule showing the banked rate adjustment authority available, by class, and the available amount for each of the preceding 5 years calculated as required by subpart H of this part. (d) The calculation of the percentage change in rates, by class, calculated as required by § 3030.128. (e) The planned usage of rate adjustment authority, by class, and calculated separately for each of subparts C through H of this part, as appropriate. (f) The amount of new unused rate adjustment authority, by class, if any, that will be generated by the rate adjustment calculated as required by subpart H of this part, as applicable. (g) A schedule of the workshare discounts included with the planned rate adjustments, and a companion schedule listing the avoided costs that underlie each such discount. (h) Whenever the Postal Service establishes a new workshare discount rate, it must include with its filing: (1) A statement explaining its reasons for establishing the workshare discount; (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.
