Point three, investment income from the proceeds of the absorbent polymers' sale. That had a positive impact for the year of 20 cents per share net of tax, and six cents on the quarter. The fourth point is on the income tax expense. Income tax expense looks extremely strange, and that primarily results from the UK write downs and provisions. In the UK, we have net operating loss, and at this stage it's not assured that we would be able to use those against future profitability.
Fifth point is obviously the discontinued operations, which are the polymer sale.
And there, there is an adjustment that occurred in the fourth quarter, relative to the incumbent loss from operations of the absorbent polymers segment, which is a tax adjustment, and then the gain on the disposal of the absorbent polymer segment shows a gain in the fourth quarter. This is the cleanup of all of the accruals, taxes, and also resolution of the disputed items. And the last point is an older point, but the extraordinary loss on the early extinguishment of debt. This was our credit, actually our note with Principle Life Insurance Company, that we were required to pay back when we closed the super absorbent polymer sale. As it turns out, with interests rates declining, this will have a positive impact on us going forward.
