Summary

Within 18 months after the law takes effect, the Postal Regulatory Commission must write rules to stop market-dominant products from paying for competitive products, make each competitive product cover its own attributable costs, and require all competitive products together to pay an appropriate share of the Postal Service’s institutional costs. Starting 5 years after the law and every 5 years after that, the Commission must review whether that institutional-cost sharing rule should stay, be changed, or be removed, looking at market conditions and whether some costs are mainly tied to competitive products.

(a)In General.—
The Postal Regulatory Commission shall, within 18 months after the date of enactment of this section, promulgate (and may from time to time thereafter revise) regulations to—
(1)prohibit the subsidization of competitive products by market-dominant products;
(2)ensure that each competitive product covers its costs attributable; and
(3)ensure that all competitive products collectively cover what the Commission determines to be an appropriate share of the institutional costs of the Postal Service.
(b)Review of Minimum Contribution.—
Five years after the date of enactment of this section, and every 5 years thereafter, the Postal Regulatory Commission shall conduct a review to determine whether the institutional costs contribution requirement under subsection (a)(3) should be retained in its current form, modified, or eliminated. In making its determination, the Commission shall consider all relevant circumstances, including the prevailing competitive conditions in the market, and the degree to which any costs are uniquely or disproportionately associated with any competitive products.
