Accounting Policies [Abstract]
Basis of presentation	The accompanying interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany transactions and balances have been eliminated upon consolidation. All foreign currency amounts in the condensed consolidated statement of operations and comprehensive loss have been translated using an average rate for the reporting period. All foreign currency balances in the balance sheet have been translated using the spot rate at the end of the reporting period. All figures expressed, except share amounts, are in U.S. dollars in millions.
Use of estimates	The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. On an ongoing basis, the Company’s management evaluates estimates, including those related to contingent assets and liabilities as of the date of the consolidated financial statements as well as the reported amounts of revenue and expense during the reporting period. Such estimates are based on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities at the dates of the condensed consolidated financial statements, and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Significant estimates reflected in the Company’s condensed consolidated financial statements include, but are not limited to, reserves for loss and loss adjustment expense, reinsurance recoverable on unpaid losses, intangible assets, and valuation allowance on deferred tax assets
Cash, cash equivalents and restricted cash	Cash and cash equivalents consist primarily of bank deposits and money market accounts with maturities of three months or less at the date of acquisition and are stated at cost, which approximates fair value. The Company’s restricted cash primarily relates to security deposits for certain office leases. The Company also collects insurance policy premiums that it holds in a segregated cash account for transmittal to the underwriting carrier, or settlement of insurance related claims. The carrying value of restricted cash approximates fair value.
New Accounting Pronouncements	There are no new accounting standards not yet implemented that are expected to have a material effect on the Company's consolidated financial statements.
