Included in the results for 2013 is an out-of-period adjustment of $3.1 million made to correct an error related to the estimate of the tax benefit for certain equity compensation grants exercised during 2012. The Company determined that the impact of the error was not significant to the current or prior period, and accordingly a restatement of the prior period tax expense was not deemed to be necessary. The low effective rate for 2013 of 15.7% is primarily due to the net tax benefit from the release of foreign valuation allowances of $11.6 million  and due to earnings from foreign jurisdictions which are taxed at a lower rate.We continually review the need for establishing or releasing valuation allowances on our deferred tax attributes. Following the Merger in the second quarter of 2012, the Company analyzed its need for maintaining valuation reserves against the expected U.S. future tax benefits. Based on that analysis the Company determined that as of June 30, 2012 there existed sufficient evidence in the form of future taxable income from the combined operations to release $126.1 million of the valuation allowance that had been previously recorded against the U.S. deferred income tax assets. Also in 2012, valuation allowances in the amount of $19.0 million were released in certain foreign jurisdictions. In 2013, the company had a net tax benefit from the release and generation of valuation allowances in certain foreign jurisdictions in the amount of $11.6 million  due to there being sufficient evidence in the form of future taxable income in those jurisdictions. The resulting deferred tax assets are comprised principally of net operating loss carryforwards that are expected to be fully realized within the expiration period and other temporary differences.For 2012, we recorded an income tax benefit from continuing operations of $121.4 million on a loss before taxes of $4.4 million. The tax benefit for 2012 was primarily due to the $145.1 million release of certain valuation allowances. For the year ended December 31, 2011, income tax expense from continuing operations was $24.3 million on income before taxes of $42.9 million. The high effective rate for 2011 of 56.6% was due to net increases in the valuation allowance of $5.4 million. No tax benefit was being provided on losses incurred in the U.S. and certain foreign jurisdictions where valuation allowances were recorded against certain tax benefits.The effective tax rates for discontinued operations were 35.0%, 25.6% and 13.4% in 2013, 2012 and 2011, respectively. The lower rate in 2011 reflects the benefit of the goodwill tax basis and prior year capital loss carryforwards that reduced the taxable gain on the sale of GBC Fordigraph in Australia.The U.S. federal statute of limitations remains open for the year 2010 and forward. Foreign and U.S. state jurisdictions have statutes of limitations generally ranging from 3 to 5 years. Years still open to examination by foreign tax authorities in major jurisdictions include Australia (2009 forward), Brazil (2008 forward), Canada (2005 forward) and the U.K. (2011 forward). We are currently under examination in various foreign jurisdictions.The components of the income tax expense from continuing operations were as follows:(in millions of dollars)2013 2012 2011Current expense      Federal and other$0.8 $6.0 $0.3Foreign25.3 27.1 19.8Total current income tax expense26.1 33.1 20.1Deferred (benefit) expense      Federal and other(2.8) (129.5) 4.9Foreign(8.9) (25.0) (0.7)Total deferred income tax (benefit) expense (11.7) (154.5) 4.2Total income tax expense (benefit)$14.4 $(121.4) $24.3The components of deferred tax assets (liabilities) were as follows:(in millions of dollars)2013 2012Deferred tax assets    Compensation and benefits$17.6 $15.6 Pension19.0 38.5 Inventory7.2 5.8 Other reserves20.9 18.0 Accounts receivable6.8 6.0 Foreign tax credit carryforwards20.5 20.5 Net operating loss carryforwards113.5 135.2 Other8.8 6.3Gross deferred income tax assets214.3 245.9 Valuation allowance(33.0) (55.4)Net deferred tax assets181.3 190.5Deferred tax liabilities    Depreciation(19.6) (27.3) Identifiable intangibles(260.0) (257.4) Unrealized foreign currency gain on intercompany debt— (3.3)Gross deferred tax liabilities(279.6) (288.0)Net deferred tax liabilities$(98.3) $(97.5)Deferred income taxes are not provided on certain undistributed earnings of foreign subsidiaries that are expected to be permanently reinvested in those companies, which aggregate to approximately $606 million and $586 million as of December 31, 2013 and at 2012, respectively. If these amounts were distributed to the U.S., in the form of a dividend or otherwise, we would be subject to additional U.S. income taxes. Determination of the amount of unrecognized deferred income tax liabilities on these earnings is not practicable.At December 31, 2013, $334.6 million of net operating loss carryforwards are available to reduce future taxable income of domestic and international companies. These loss carryforwards expire in the years 2014 through 2032 or have an unlimited carryover period.Interest and penalties related to unrecognized tax benefits are recognized within "Income tax expense (benefit)" in the Consolidated Statements of Income. As of December 31, 2013, we have accrued a cumulative amount of $3.6 million for interest and penalties on unrecognized tax benefits.A reconciliation of the beginning and ending amount of unrecognized tax benefits were as follows:(in millions of dollars)2013 2012 2011Balance at beginning of year$56.3 $5.5 $5.7Additions for tax positions of prior years2.4 2.0 0.1Reductions for tax positions of prior years— (1.5) (0.2)Settlements(0.1) — (0.1)Mead C&OP acquisition— 50.3 —Foreign exchange changes(6.5) — —Balance at end of year$52.1 $56.3 $5.5As of December 31, 2013 the amount of unrecognized tax benefits decreased to $52.1 million, of which $47.4 million would affect our effective tax rate, if recognized. We expect the amount of unrecognized tax benefits to change within the next twelve months, but these changes are not expected to have a significant impact on our results of operations or financial position. None of the positions included in the unrecognized tax benefit relate to tax positions for which the ultimate deductibility is highly certain, but for which there is uncertainty about the timing of such deductibility.Income Tax AssessmentIn connection with our May 1, 2012 acquisition of Mead C&OP we assumed all of the tax liabilities for the acquired foreign operations. In December of 2012, the Federal Revenue Department of the Ministry of Finance of Brazil ("FRD") issued a tax assessment against our newly acquired indirect subsidiary, Tilibra Produtos de Papelaria Ltda. ("Tilibra"), which challenged the tax deduction of goodwill from Tilibra's taxable income for the year 2007. A second assessment challenging the deduction of goodwill from Tilibra's taxable income for the years 2008, 2009 and 2010 was issued by FRD in October 2013. The assessments seek payment of approximately R95.2 million ($40.4 million based on current exchange rates) of tax, penalties and interest.Tilibra is disputing both of the tax assessments through established administrative procedures. We believe we have meritorious defenses and intend to vigorously contest these matters; however, there can be no assurances that we will ultimately prevail. We are in the early stages of the process to challenge the FRD's tax assessments, and the ultimate outcome will not be determined until the Brazilian tax appeal process is complete, which is expected to take a number of years. In addition, Tilibra's 2011-2012 tax years remain open and subject to audit, and there can be no assurances that we will not receive additional tax assessments regarding the goodwill deducted for the Tilibra acquisition for one or more of those years. If the FRD's initial position is ultimately sustained, the amount assessed would adversely affect our cash flow in the year of settlement.Because there is no settled legal precedent on which to base a definitive opinion as to whether we will ultimately prevail, the Company considers the outcome of this dispute to be uncertain. Since it is not more likely than not that we will prevail, in the fourth quarter of 2012, we recorded a reserve in the amount of $44.5 million in consideration of this contingency , of which $43.3 million was recorded as an adjustment to the purchase price and included the 2008-2012 tax years plus interest and penalties through December 2012. In addition, the Company will continue to accrue interest related to this contingency until such time as the outcome is known or until evidence is presented that we are more likely than not to prevail. During 2013 and 2012, the Company accrued additional interest as a charge to current tax expense of $1.8 million and $1.2 million, respectively. |
