(1) Schedule rate adjustments at specific regular intervals of time;

(2) Provide estimated filing and implementation dates (month and year) for future rate adjustments for each class of mail expected over a minimum of the next 3 years; and

(3) Provide an explanation that will allow mailers to predict with reasonable accuracy, by class, the amounts of future scheduled rate adjustments.

(b) The Postal Service shall file a current Schedule for Regular and Predictable Rate Adjustments annually with the Commission at the time of filing the Postal Service's section 3652 report (see § 3050.1(g) of this chapter). The Commission shall post the current schedule on the Commission's website at www.prc.gov.

(c) Whenever the Postal Service deems it appropriate to change the Schedule for Regular and Predictable Rate Adjustments, it shall file a revised schedule.

(d) The Postal Service may vary the magnitude of rate adjustments from those estimated by the Schedule for Regular and Predictable Rate Adjustments. In such case, the Postal Service shall provide an explanation for such variation with its rate adjustment filing.
