(b) The Commission will review the calculation of the assumed Federal income tax submitted pursuant to § 3060.40, the supporting documentation submitted pursuant to § 3060.41, and any comments. The Commission then will issue an order either approving the calculation of the assumed Federal income tax for that tax year or take such other action as the Commission deems appropriate, including, but not limited to, directing the Postal Service to file additional supporting materials.

Upon receipt of the Postal Service's responsive pleading, the Commission may order such action as it deems appropriate.
