Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The Company and its Bermuda domiciled subsidiaries are not subject to Bermuda income tax under current Bermuda law. In the event there is a change in the current law such that taxes are imposed, the Company and its Bermuda domiciled subsidiaries would be exempt from such tax until March 31, 2035, pursuant to the Bermuda Exempted Undertakings Tax Protection Act of 1966. The Company has subsidiaries and branches that operate in various other jurisdictions around the world that are subject to tax in the jurisdictions in which they operate. The jurisdictions in which the Company’s subsidiaries and branches are subject to tax are Australia, Belgium, Canada, Germany, Gibraltar, Luxembourg, the Netherlands, Singapore, Sweden, Switzerland, the United Kingdom and the United States. The total income tax benefit (expense) for the years ended December 31, 2012, 2011 and 2010 consisted of the following:

In 2012, new tax legislation was enacted in Sweden, which was effective January 1, 2013, that reduces the corporate tax rate from 26.3% to 22.0%. This resulted in a reduction of $65.4 million in Sirius Group’s deferred tax liabilities in Sweden. The non-U.S. component of pre-tax income was $250.0 million, $65.4 million and $74.4 million for the years ended December 31, 2012, 2011 and 2010. Tax Payments and Receipts Net income tax payments to (receipts from) national governments (primarily the United States) totaled $17.5 million, $12.5 million, and $(47.0) million for the years ended December 31, 2012, 2011 and 2010. Deferred Tax Inventory Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts for tax purposes. An outline of the significant components of White Mountains’ deferred tax assets and liabilities follows:

White Mountains’ deferred tax assets are net of U.S. federal, state, and non-U.S. valuation allowances and, to the extent they relate to non-U.S. jurisdictions, they are shown at year-end exchange rates. Valuation Allowance White Mountains records a valuation allowance against deferred tax assets if it becomes more likely than not that all or a portion of a deferred tax asset will not be realized. Changes in valuation allowances from period to period are included in income tax expense in the period of change. In determining whether or not a valuation allowance, or change therein, is warranted, White Mountains considers factors such as prior earnings history, expected future earnings, carryback and carryforward periods and strategies that if executed would result in the realization of a deferred tax asset. It is possible that certain planning strategies or projected earnings in certain subsidiaries may not be feasible to utilize the entire deferred tax asset, which could result in material changes to White Mountains' deferred tax assets and tax expense. Of the $254.0 million valuation allowance at December 31, 2012, $192.0 million relates to deferred tax assets on net operating losses in Luxembourg subsidiaries (discussed below under “Net Operating Loss and Capital Loss Carryforwards”) and $62.0 million relates to deferred tax assets on U.S. losses and other federal deferred tax benefits. Of the $232.6 million valuation allowance at December 31, 2011, $225.5 million relates to deferred tax assets on net operating losses in Luxembourg subsidiaries (discussed below under “Net Operating Loss and Capital Loss Carryforwards”) and $6.9 million relates to deferred tax assets on U.S. losses and other federal deferred tax benefits. Luxembourg During the fourth quarters of 2012 and 2011, White Mountains recorded net tax benefits of $41.3 million and $129.5 million from the net release of valuation allowances against deferred tax assets in Luxembourg-domiciled subsidiaries. These companies had built up substantial deferred tax assets due to net operating loss carryforwards (“NOLs”). The loss carryforwards primarily relate to tax deductible write downs in 2007 and 2008 of investments in U.S. subsidiaries. There were partial valuation allowances on these deferred tax assets in periods prior to the fourth quarter of 2012 and 2011 because the companies did not expect sufficient future taxable income to utilize them. During the fourth quarter of 2012 and 2011, Sirius Group undertook a series of reorganizations to optimize operational and capital efficiency. As part of the reorganizations, investments and outstanding internal debt instruments were contributed to Luxembourg-domiciled subsidiaries with net operating loss carryforwards. One of the companies, S.I. Holdings (Luxembourg) S.à r.l., (“SI Holdings”) (formerly OneBeacon Holdings (Luxembourg) S.à r.l.), was acquired from OneBeacon on January 24, 2012. As the plan for the Sirius Group to acquire SI Holdings and contribute the notes was in place on December 31, 2011, and this was a transaction between entities under common control, White Mountains accounted for the tax effects of the transaction as if it had occurred in 2011. An investment portfolio was contributed to SI Holdings in January 2013, pursuant to a plan in place on December 31, 2012, that will generate income utilizing the deferred tax asset over an extended period of time. The deferred tax assets for the remaining NOLs at the companies are offset by a valuation allowance as no additional taxable income is expected. United States During the fourth quarter 2012, White Mountains recorded tax expense of $37.8 million to establish a valuation allowance against deferred tax assets of Guilford Holdings, Inc. and subsidiaries (“Guilford”), as White Mountains management determined that the strategies supporting the deferred tax assets were no longer feasible to utilize the assets. Guilford consists of service companies that are included in the Other Operations segment. During the fourth quarter 2012, White Mountains recorded tax expense of $3.9 million to establish a valuation allowance against deferred tax assets related to foreign tax credit carryforwards at Sirius Re Holdings, Inc. and subsidiaries (“SRHI”) that expire in 2016 and 2017. SRHI is no longer expected to generate sufficient taxable income to utilize these credits. SRHI has an additional $4.6 million of foreign tax credits that expire in 2018-2022 that are still expected to be utilized. During 2012, White Mountains recorded tax expense of $13.7 million to establish valuation allowances against deferred tax assets of BAM and Houston General Insurance Exchange (“Houston General Insurance”) as it is uncertain if these companies will have sufficient taxable income to utilize their deferred tax assets. However, since BAM and Houston General Insurance are mutual insurance companies that are owned by their members, their results do not affect White Mountains’ common shareholders’ equity as they are attributable to non-controlling interests. Net Operating Loss and Capital Loss Carryforwards Net operating loss and capital loss carryforwards as of December 31, 2012, the expiration dates and the deferred tax assets thereon are as follows:

White Mountains expects to utilize net operating loss carryforwards in Luxembourg of $1,308.5 million but does not expect to utilize the remainder as they belong to companies that are not expected to have sufficient income in the future. These losses primarily relate to tax deductible write-downs in 2007 and 2008 of investments in U.S. subsidiaries held by Luxembourg subsidiaries. Included in the U.S. net operating loss carryforwards are losses of $29.0 million subject to an annual limitation on utilization under Internal Revenue Code Section 382. At December 31, 2012, there were U.S. foreign tax credit carryforwards available of $10.6 million, which begin to expire in 2016. As discussed above, a deferred tax valuation allowance of $3.9 million has been established for these credits. At December 31, 2012, there were U.S. low-income housing tax credit carryforwards available of $4.8 million, which begin to expire in 2031. At December 31, 2012, there were U.S. investment tax credit carryforwards available of $0.2 million, which begin to expire in 2031. Also, at December 31, 2012, there were U.S. alternative minimum tax credit carryforwards of $1.5 million which do not expire. During 2010, White Mountains International S.à r.l. (“WMI”) received a tax ruling in Luxembourg which allowed it to change its tax functional currency in Luxembourg to the Swedish krona from the euro. Pursuant to the ruling, WMI revalued its NOL carryforwards in Luxembourg using the December 31, 2008 euro/krona exchange rate. This resulted in WMI recording an $11.9 million deferred tax benefit in 2010 for the increase in its NOLs in Luxembourg. Uncertain Tax Positions Under ASC 740-10, recognition of the benefit of a given tax position is based upon whether a company determines that it is more likely than not that a tax position will be sustained upon examination based upon the technical merits of the position. In evaluating the more-likely-than-not recognition threshold, White Mountains must presume that the tax position will be subject to examination by a taxing authority with full knowledge of all relevant information. If the recognition threshold is met, then the tax position is measured at the largest amount of benefit that is more than 50% likely of being realized upon ultimate settlement. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
Millions |  | Permanent Differences (1) |  | Temporary Differences (2) |  | Interest and Penalties (3) |  | Total

(1) | Represents the amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate.
(2) | Represents the amount of unrecognized tax benefits that, if recognized would create a temporary difference between the reported amount
of an item in the Company’s Consolidated Balance Sheet and its tax basis.
(3) | Net of tax benefit.
If White Mountains determines in the future that its reserves for unrecognized tax benefits on permanent differences and interest and penalties are not needed, the reversal of $17.7 million of such reserves at December 31, 2012 would be recorded as an income tax benefit and would impact the effective tax rate. If White Mountains determines in the future that its reserves for unrecognized tax benefits on temporary differences are not needed, the reversal of $28.9 million of such reserves at December 31, 2012 would not impact the effective tax rate due to deferred tax accounting but would accelerate the payment of cash to the taxing authority. The vast majority of White Mountains’ reserves for unrecognized tax benefits on temporary differences relate to deductions for loss reserves that the timing of the deductions is uncertain. White Mountains classifies all interest and penalties on unrecognized tax benefits as part of income tax expense. During the years ended December 31, 2012, 2011 and 2010 White Mountains recognized $1.2 million, $0.6 million, $1.9 million in interest (benefit) expense, net of any tax benefit. The balance of accrued interest at December 31, 2012 and 2011 is $8.0 million and $6.8 million, net of any tax benefit. Tax Examinations With few exceptions, White Mountains is no longer subject to U.S. federal, state or non-U.S. income tax examinations by tax authorities for years before 2005. The IRS is conducting an examination of income tax returns for 2005 and 2006 for certain U.S. subsidiaries of OneBeacon. On January 5, 2011, White Mountains received Form 4549-A (Income Tax Discrepancy Adjustments) from the IRS relating to the examination of tax years 2005 and 2006. The estimated total assessment, including interest and utilization of alternative minimum and foreign tax credit carryovers, is $20.8 million. White Mountains disagrees with the adjustments proposed by the IRS and is defending its position. Although the timing of the resolution of these issues is uncertain, it is reasonably possible that the resolution could occur within the next 12 months. An estimate of the range of potential outcomes cannot be made at this time. When ultimately settled, White Mountains does not expect the resolution of this examination to result in a material change to its financial position. On July 28, 2011, the IRS commenced an examination of the income tax returns for 2007, 2008 and 2009 for certain U.S. subsidiaries of OneBeacon. White Mountains has received proposed adjustments but does not expect the resolution of this examination to result in a material change to its financial position. On December 15, 2011, the IRS commenced an examination of the income tax returns for 2010 for certain U.S. subsidiaries of AFI. Pursuant to a Stock Purchase Agreement dated as of May 17, 2011 between White Mountains and Allstate, White Mountains is required to indemnify Allstate for any changes in pre-closing taxes. White Mountains does not expect the resolution of this examination to result in a material change to its financial position. The IRS conducted an examination of income tax returns for 2006 and 2007 for certain U.S. subsidiaries of Sirius Group. On October 26, 2011, the Sirius Group received and signed the IRS Revenue Agent’s Report, which contained no proposed adjustments. The IRS also examined the U.S. income tax return filed by WM Belvaux S.à r.l., a Luxembourg subsidiary, for tax year 2007. On May 3, 2011, the exam was completed with no proposed adjustments.
