Debt Disclosure [Abstract]

Schedule of Recent Accounting and Reporting Developments

Standard	Summary of guidance		Effects on financial statements and/or disclosures
Presentation of Debt Issuance Costs	•	Requires the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of as a deferred charge.	•	Adopted March 31, 2016 with retrospective application to prior periods.
	•	Does not impact the amortization method for these costs.	•	There was no material impact on the consolidated balance sheets, and no impact on our statements of operations.
			•	For further information, see Note 7. "Debt."
Accounting for Share-Based Compensation When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period	•	Requires that a performance target that affects vesting and that can be achieved after the requisite service period be treated as a performance condition.	•	Adopted March 31, 2016 with application to performance based awards granted in 2016.
	•	Compensation cost should be recognized in the period in which it become probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which service has been rendered.	•	There was no material impact on our consolidated financial statements.
	•	If the performance target becomes probable of being achieved before the end of the service period, the remaining unrecognized compensation cost for which requisite service has not yet been rendered is recognized prospectively over the remaining service period.	•	For further information, see Note 15. "Share-based Compensation Plans".
Disclosures about Short-Duration Contracts	•	Requires expanded disclosures designed to provide additional insight into an insurance entity's ability to underwrite and anticipate costs associated with claims.	•	This standard is not considered applicable to our business and therefore we have not adopted these disclosure requirements.
	•	Disclosures include information about incurred and paid claims development, on a net of reinsurance basis, for the number of years claims incurred typically remain outstanding not to exceed ten years.
	•	Expanded disclosures also include more transparent information about significant changes in methodologies and assumptions used to estimate claims, and the timing, frequency, and severity of claims.
Classification of Certain Cash Receipts and Cash Payments	•	Provides specific guidance on the presentation of certain cash flow items including, but not limited to, debt prepayment and debt issuance costs and proceeds from the settlement of insurance claims.	•	Adopted December 31, 2016 with application to prior periods.
			•	Cash flows related to debt prepayment and debt issuance transactions have been reclassified as financing activities from operating activities.
			•	For further information on the impact our transactions had on our cash and cash equivalents see our consolidated statements of cash flows.

Financial Accounting Standards Board ("FASB") Standards Issued but not yet Adopted
Standard	Summary of guidance		Effects on financial statements and/or disclosures
Recognition and Measurement of Financial Assets and Financial Liabilities Issued January 2016	•	Requires equity investments, except those accounted for under the equity method of accounting that have a readily determinable fair value to be measured at fair value with changes in fair value recognized in earnings.	•	Required effective date: January 1, 2018.
	•	Equity investments that do not have readily determinable fair values may be remeasured at fair value either upon the occurrence of an observable price change or upon identification of an impairment. A qualitative assessment for impairment is required for equity investments without readily determinable fair values.	•	The potential impact from the adoption of this guidance is not expected to have a material impact our consolidated balance sheets, consolidated statements of operations, or liquidity.
	•	Requires recognition of a cumulative effect adjustment to retained earnings as of the beginning of the reporting period of adoption.	•	For further information on our current equity investments see Note 5. "Investments."
Improvements to Employee Share-Based Compensation Accounting Issued March 2016	•	Requires that, prospectively, all tax effects related to share-based compensation be made through the statement of operations at the time of settlement, rather than recognizing excess tax benefits within paid-in capital.	•	Required effective date: January 1, 2017.
	•	Removes the requirement to delay recognition of a tax benefit until it reduces current taxes payable. This change is required to be applied on a modified retrospective basis.	•	We are currently evaluating the impacts the adoption of this guidance will have on our consolidated financial statements.
	•	Requires all tax related cash flows resulting from share-based compensation to be reported as operating activities, a change from the existing requirement to present tax benefits as an inflow from financing activities and an outflow from operating activities.
	•	Entities, for tax withholding purposes, will be allowed to withhold an amount of shares up to an employee's maximum individual tax rate (as opposed to the minimum statutory tax rate) in the relevant jurisdiction without resulting in liability classification of the award.
Measurement of Credit Losses on Financial Statements Issued June 2016	•	Requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial instruments. Entities are required to use a current expected credit loss ("CECL") methodology that incorporates their forecasts of future economic conditions, unless such forecast is not reasonable or supportable, in which case the entity will revert to historical loss experience.	•	Required effective date: January 1, 2020.
	•	Amends existing guidance for available-for-sale fixed income securities to incorporate an allowance, rather than a write-down of the asset, with the amount of the allowance limited to the amount by which the fair value is less than amortized cost. The guidance will allow for reversals of impairment losses in the event that the credit of an issuer improves. The length of time a security has been in an unrealized loss position will no longer impact the determination of whether a credit loss exists.	•	We are currently evaluating the impacts the adoption of this guidance will have on our consolidated financial statements, but do not expect it to have a material impact.
	•	Updated guidance is not prescriptive about certain aspects of estimating expected credit losses, including the specific methodology to use, and therefore will require significant judgment in application.
