[1] (Loss) income from continuing operations, net of tax during 2016 was impacted by a charge for valuation allowances for deferred tax assets outside of the U.S of $8.6, which was recorded in the fourth quarter, the release of a valuation allowance associated with Russia of $7.1 which was recorded in the second quarter, and an income tax benefit of $29.3 recognized as the result of the implementation of foreign tax planning strategies which was recorded in the first quarter.

[2] (Loss) income from continuing operations, before taxes during 2016 was impacted by:•the deconsolidation of our Venezuelan operations. As a result of the change to the cost method of accounting, in the first quarter of 2016 we recorded a loss of $120.5 in other expense, net. The loss was comprised of $39.2 in net assets of the Venezuelan business and $81.3 in accumulated foreign currency translation adjustments within AOCI associated with foreign currency movements before Venezuela was accounted for as a highly inflationary economy;•a gain on extinguishment of debt of $3.9 before and after tax in the third quarter caused by the deferred gain associated with interest-rate swap agreement terminations, partially offset by the early tender premium paid, the deferred loss associated with treasury lock agreements, deal costs and the write-off of debt issuance costs and discounts associated with the cash tender offers in August 2016;•a loss on extinguishment of debt of $1.0 before and after tax in the fourth quarter caused by the premium paid for the repurchases, the write-off of debt issuance costs and discounts and the deferred loss associated with treasury lock agreements, partially offset by the deferred gain associated with interest-rate swap agreement terminations associated with the debt repurchases in October 2016;•a loss on extinguishment of debt of $2.9 before and after tax in the fourth quarter caused by the make-whole premium, the deferred loss associated with treasury lock agreements and the write-off of debt issuance costs and discounts and partially offset by the deferred gain associated with interest-rate swap agreement terminations associated with the prepayment of the remaining principal amount of the 4.20% Notes (as defined in Note 7, Debt and Other Financing) and 5.75% Notes (as defined in Note 7, Debt and Other Financing); and•a gain on extinguishment of debt of $1.1 before and after tax in the fourth quarter consisting of the discount received for the repurchases, partially offset by the write-off of debt issuance costs and discounts associated with the debt repurchases in December 2016.

[3] The sum of per share amounts for the quarters does not necessarily equal that for the year because the computations were made independently.
