New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	In April 2014, the Financial Accounting Standards Board (“FASB”) issued an update to the accounting standard for reporting discontinued operations and disclosures of disposals of components of an entity. This update changes the requirements for reporting discontinued operations. A disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents (or would represent) a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when any of the following occurs: (a) the component of an entity or group of components of an entity meets the criteria to be classified as held for sale; (b) the component of an entity or group of components of an entity is disposed of by sale; or (c) the component of an entity or group of components of an entity is disposed of other than by sale (for example, by abandonment or in a distribution to owners in a spin-off). The amendments in this update require expanded disclosures about discontinued operations. The provisions of this update are effective for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	In May 2014, the FASB issued an update to the accounting standard regarding revenue recognition. This update is intended to provide a consistent approach in recognizing revenue. In accordance with the new standard, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the new standard requires that reporting companies disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. While this update is not expected to change revenue recognition principles related to our insurance products, this update may be applicable to revenues from our Services segment, which has been included in our condensed consolidated statements of operations beginning with the third quarter of 2014. The provisions of this update are effective for interim and annual periods beginning after December 15, 2016.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	In April 2015, the FASB issued an update to the accounting standard for the presentation of debt issuance costs in financial statements. The new standard requires an entity to present debt issuance costs related to a recognized debt liability as a direct reduction from the carrying amount of the related debt liability, consistent with debt discounts, rather than as a separate asset as currently required. The recognition and measurement guidance for debt issuance costs are not affected by the update. The provisions of this update are effective for interim and annual periods beginning after December 15, 2015 and must be applied on a retrospective basis for all periods presented. Early adoption is permitted for financial statements that have not been previously issued. Upon adoption, the standard requires an entity to disclose: (a) the nature of and reason for the change in accounting principle; (b) the transition method; (c) a description of the prior period information that has been retrospectively adjusted; and (d) the effect of the change on the financial statement line items.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	In April 2015, the FASB issued an update to the accounting standard for the accounting of internal-use software. The amendments in this update provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The provisions of this update are effective for interim and annual periods beginning after December 15, 2015, and early adoption is permitted.
