Income Tax Disclosure [Abstract]
8. Income taxes	The 2017 Tax Reform Act (the “Tax Reform Act”) was enacted on December 22, 2017. The Tax Reform Act reduces the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. A 31.55% Federal Tax Rate will apply to earnings for the full 2018 fiscal year. Accordingly, first and second quarter income previously subject to tax at the 35% Federal Tax Rate will benefit from the 31.55% Federal Tax Rate. At December 31, 2017, we have not completed our accounting for the tax effects of enactment of the Tax Reform Act; however, we have made a reasonable estimate of the effects of all items affected by the Tax Reform Act. For these items, we recognized a provisional benefit amount of $339.2 million, which is included as a component of income tax expense from continuing operations. Provisional amounts: We re-measured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. However, we are still analyzing certain aspects of the Tax Reform Act and refining our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The provisional amount recorded related to the re-measurement of our deferred tax balance was $349.2 million. Foreign tax effects: The one-time transition tax is based on our total post-1986 earnings and profits (“E&P”) from our Canadian subsidiaries that we previously deferred from U.S. income taxes. We recorded a provisional amount for our one-time transition tax liability for our foreign subsidiaries, resulting in an increase in income tax expense of $10.0 million. We have not yet completed our calculation of the total post-1986 E&P for these foreign subsidiaries. Further, the transition tax is based in part on the amount of those earnings held in cash and other specified assets. This amount may change when we finalize the calculation of post-1986 foreign E&P previously deferred from U.S. federal taxation and finalize the amounts held in cash or other specified assets. No additional income taxes have been provided for any remaining undistributed foreign earnings not subject to the transition tax, or any additional outside basis difference inherent in these entities, as these amounts continue to be indefinitely reinvested in foreign operations. Determining the amount of unrecognized deferred tax liability related to any remaining undistributed foreign earnings not subject to the transition tax and additional outside basis difference in these entities (i.e., basis difference in excess of that subject to the one-time transition tax) is not practicable. Insurance Companies: Our insurance companies are included in this financial statement at a one quarter lag, meaning the nine month period ended September 30, 2017. As such, the effects of the Tax Reform Act on Repwest and Oxford are not recognized in these financial statements as presented. If the effects of the Tax Reform Act were applied to our Insurance Company balances as presented, the result would have been as follows: With regard to Oxford; we estimate a provisional tax benefit of $5.1 million, which would be a component of income tax expense from continuing operations. The Financial Accounting Standards Board (“FASB”) is still reviewing the treatment of certain deferred tax accounts which could change the ultimate presentation of where these amounts are recorded. We estimated the re-measured deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. The provisional amount resulting from the re-measurement of the deferred tax liability balance would be a reduction in tax expense of about $9.1 million. In addition, the Tax Reform Act repeals the special rules with regard to distribution to shareholders from pre-1984 policyholders surplus account. The one-time tax was based on the balance of our pre-1984 policyholder surplus account. We estimated a provisional amount for our one-time tax liability for Phase Three Tax, resulting in a increase in income tax expense of $4.0 million. With regard to Repwest; we estimate a provisional tax benefit of $5.4 million, which would be a component of income tax expense from continuing operations. This provisional amount would result from the re-measurement of the deferred tax liability balance. We estimated the re-measured deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%.

Provisional amounts:

We re-measured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. However, we are still analyzing certain aspects of the Tax Reform Act and refining our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The provisional amount recorded related to the re-measurement of our deferred tax balance was $349.2 million.

Foreign tax effects:

The one-time transition tax is based on our total post-1986 earnings and profits (“E&P”) from our Canadian subsidiaries that we previously deferred from U.S. income taxes. We recorded a provisional amount for our one-time transition tax liability for our foreign subsidiaries, resulting in an increase in income tax expense of $10.0 million. We have not yet completed our calculation of the total post-1986 E&P for these foreign subsidiaries. Further, the transition tax is based in part on the amount of those earnings held in cash and other specified assets. This amount may change when we finalize the calculation of post-1986 foreign E&P previously deferred from U.S. federal taxation and finalize the amounts held in cash or other specified assets. No additional income taxes have been provided for any remaining undistributed foreign earnings not subject to the transition tax, or any additional outside basis difference inherent in these entities, as these amounts continue to be indefinitely reinvested in foreign operations. Determining the amount of unrecognized deferred tax liability related to any remaining undistributed foreign earnings not subject to the transition tax and additional outside basis difference in these entities (i.e., basis difference in excess of that subject to the one-time transition tax) is not practicable.
