Income Tax Disclosure [Abstract] |
INCOME TAXES | Under current Bermuda law, our Bermuda domiciled companies are not required to pay any taxes in Bermuda on income or capital gains. We have received an assurance from the Minister of Finance in Bermuda that, in the event of any taxes being imposed, we will be exempt from taxation in Bermuda until March 2035. Our primary Bermuda subsidiary has an operating branch in Singapore, which is subject to the relevant taxes in that jurisdiction. The branch is not under examination in this tax jurisdiction, but remains subject to examination for tax years 2012 through 2015. Our U.S. subsidiaries are subject to federal, state and local corporate income taxes and other taxes applicable to U.S. corporations. The provision for federal income taxes has been determined under the principles of the consolidated tax provisions of the U.S. Internal Revenue Code and Regulations. Should the U.S. subsidiaries pay a dividend outside the U.S. group, withholding taxes will apply. Our U.S. subsidiaries are not under examination but remain subject to examination in the U.S. for tax years 2012 through 2015. In Canada, our U.S. reinsurance company operates through a branch and our U.S. service company has an unlimited liability company subsidiary based in Canada. These Canadian operations are subject to the relevant taxes in that jurisdiction and generally remain subject to examination for tax years 2011 through 2015. We also have subsidiaries in Ireland, the United Kingdom (U.K.), Australia and Brazil. These subsidiaries and their branches, are not under examination, but generally remain subject to examination in all applicable jurisdictions for tax years 2011 through 2015. The following table provides an analysis of our income tax expense and net tax assets:

The following table provides an analysis of the movement in our valuation allowance:
| At December 31, | 2015 |  | 2014 |
| Income tax expense: |  |  |  |
| Valuation allowance - beginning of year | $ | 34,865 |  |  | $ | 27,070 |  |
| Operating loss carryforwards | 6,809 |  |  | 3,044 |  |
| Capital loss carryforwards | — |  |  | 1,262 |  |
| Foreign tax credit | (1,573 | ) |  | 3,194 |  |
| Australian CTA and accruals and other foreign rate differentials | 1,001 |  |  | 1,052 |  |
| Change in investment-related items | (771 | ) |  | (757 | ) |
| Valuation allowance - end of year | 40,331 |  |  | 34,865 |  |
| Accumulated other comprehensive income: |  |  |  |
| Valuation allowance - beginning of year | (771 | ) |  | (1,528 | ) |
| Change in investment-related items | 771 |  |  | 757 |  |
| Valuation allowance - end of year | — |  |  | (771 | ) |
| Total valuation allowance - end of year | $ | 40,331 |  |  | $ | 34,094 |  |
At December 31, 2015 and 2014, we established a full valuation allowance on: (1) operating and capital loss carryforwards relating to operations in Australia and Singapore; (2) unutilized foreign tax credits available in Ireland and (3) certain other deferred tax assets related to branch operations. Although realization is not assured, management believes it is more likely than not that the tax benefit of the recorded net deferred tax assets will be realized. Other than the items discussed above, the remaining gross deferred tax assets relate substantially to our U.S. operations. In evaluating our ability to recover these tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including historical results, operating loss carryback potential and scheduled reversals of deferred tax liabilities. Our U.S. operations have produced significant taxable income in prior periods and have deferred tax liabilities that will reverse in future periods such that we believe sufficient ordinary taxable income is available to utilize all remaining ordinary deferred tax assets. In 2015 and 2014, there were sufficient net unrealized gains or capital loss carryback potential to offset remaining impairments, therefore a valuation allowance on such impairments in the U.S., was not considered necessary. There were no unrecognized tax benefits at December 31, 2015 and 2014. The following table presents the distribution of income before income taxes between domestic and foreign jurisdictions as well as a reconciliation of the actual income tax rate to the amount computed by applying the effective tax rate of 0% under Bermuda law to income before income taxes:
| Year ended December 31, | 2015 |  | 2014 |  | 2013 |
| Income before income taxes |  |  |  |  |  |
| Bermuda (domestic) | $ | 652,235 |  |  | $ | 690,517 |  |  | $ | 625,490 |  |
| Foreign | (7,576 | ) |  | 139,955 |  |  | 108,977 |  |
| Total income before income taxes | $ | 644,659 |  |  | $ | 830,472 |  |  | $ | 734,467 |  |
| Reconciliation of effective tax rate (% of income before income taxes) |  |  |  |  |  |
| Expected tax rate | 0.0 | % |  | 0.0 | % |  | 0.0 | % |
| Foreign taxes at local expected rates: |  |  |  |  |  |
