The remaining 2 checkoffs for which designations may be made and which shall be placed on the income tax form for the next 2 taxable years, in place of the 2 lowest ranking checkoffs, shall be checkoffs that have not received any designations during the previous 2-year period.3. The 2 remaining checkoffs, described under subd. 2., shall be the 2 oldest checkoffs, based on the date each checkoff was placed on a list of checkoffs, maintained by the department, that are eligible to be placed on the form. If 2 or more checkoffs have been placed on the list at the same time, the oldest checkoff shall then be calculated according to their effective dates.4.
