Tax Reporting Practices Except as provided in the following Section 3.6, with respect to any Tax Return for any taxable period that begins on or before the second anniversary of the Distribution Date with respect to which Versum is the Preparing Party, such Tax Return shall be prepared in a manner (i) consistent with past practices, accounting methods, elections and conventions (“Past Practices”) used by Air Products in preparing similar Tax Returns (unless there is no Reasonable Basis for the use of such Past Practices), and to the extent any items are not covered by Past Practices (or in the event that there is no Reasonable Basis for the use of such Past Practices), in accordance with reasonable Tax accounting practices selected by Versum; and (ii) that, to the extent consistent with the foregoing clause (i), minimizes the overall amount of Taxes due and payable on such Tax Return for all of the Parties by cooperating in making such elections or applications for group or other relief or allowances available in the taxing jurisdiction in which such Tax Return is filed. Versum shall not take any action inconsistent with the assumptions (including items of income, gain, deduction, loss and credit) made in determining all estimated or advance payments of Taxes on or prior to the Distribution Date. In addition, Versum shall not be permitted, and shall not permit any member of the Versum Group, to make a change in any of its methods of accounting for tax purposes until all applicable statutes of limitations for all Pre-Distribution Periods and Straddle Periods have expired.
