Exceptions for de minimis rate increases.

§ 3030.129 Exceptions for de minimis rate increases. (a) The Postal Service may request that the Commission review a de minimis rate increase without immediately calculating the maximum rate adjustment authority or banking unused rate adjustment authority. For the exception in this paragraph (a) to apply, requests to review de minimis rate adjustments must be filed separately from any other request to review a rate adjustment filing. (b) Rate adjustments resulting in rate increases are de minimis if: (1) For each affected class, the rate increases do not result in the percentage change in rates for the class equaling or exceeding 0.001 percent; and (2) For each affected class, the sum of all rate increases included in de minimis rate increases since the most recent rate adjustment resulting in a rate increase, or the most recent rate adjustment due to extraordinary and exceptional circumstances, that was not a de minimis rate increase does not result in the percentage change in rates for the class equaling or exceeding 0.001 percent. (c) If the rate adjustments are de minimis, no unused rate adjustment authority will be added to the schedule of banked rate adjustment authority maintained under subpart G of this part as a result of the de minimis rate increase. (d) If the rate adjustments are de minimis, no rate decreases may be taken into account when determining whether rate increases comply with paragraphs (b)(1) and (2) of this section. (e) In the next rate adjustment filing proposing to increase rates for a class that is not a de minimis rate increase: (1) The maximum rate adjustment authority shall be calculated as if the de minimis rate increase had not been filed; and (2) For purposes of calculating the percentage change in rates, the current rate shall be the current rate from the de minimis rate increase. (f) The Postal Service shall file supporting workpapers with each request to review a de minimis rate increase that demonstrate that the sum of all rate increases included in de minimis rate increases since the most recent rate adjustment resulting in a rate increase that was not de minimis, or the most recent rate adjustment due to extraordinary and exceptional circumstances, does not result in a percentage change in rates for the class equaling or exceeding 0.001 percent. (g) For any product where the attributable cost for that product exceeded the revenue from that product as determined by the Commission, rates may not be reduced.
