Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Accounting Pronouncements Accounting Standards Recently Adopted None. Accounting Standards Not Yet Adopted In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides a five-step process to achieve that core principle. ASU 2014-09 requires disclosures enabling users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, using one of two retrospective application methods. Early application is not permitted. We have evaluated the effect the guidance will have on our consolidated financial statements. We do not expect that any portion of our revenue will be affected by the new standard, primarily as the new guidance does not apply to revenue from insurance contracts and our non-insurance subsidiaries do not receive revenues from customers. The FASB’s new lease accounting standard, ASU 2016-02, Leases (Topic 842), was issued on February 25, 2016. The ASU will require organizations that lease assets, referred to as “lessees”, to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The ASU also will require disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative requirements, providing additional information about the amounts recorded in the financial statements. The accounting by organizations that own the assets leased by the lessee, also known as lessor accounting, will remain largely unchanged from current GAAP. However, the ASU contains some targeted improvements that are intended to align, where necessary, lessor accounting with the lessee accounting model and with the updated revenue recognition guidance issued in 2014. The ASU on leases will take effect for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is assessing the impact of this new standard, but currently the Company does not lease assets, so the new standard is not expected to have any effect on the Company's financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), with the main objective to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments in this ASU require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. Credit losses on available-for-sale debt securities should be measured in a manner similar to current GAAP; however, the credit losses are recorded through an allowance for credit losses rather than as a write-down. This approach is an improvement to current GAAP because an entity will be able to record reversals of credit losses (in situations in which the estimate of credit losses declines) in current period net income, which in turn should align the income statement recognition of credit losses with the reporting period in which changes occur. Current GAAP prohibits reflecting those improvements in current-period earnings. For public business entities, the amendments in this ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is evaluating the impact this guidance will have on our consolidated financial statements, but it is not expected to have a significant impact on the Company's financial statements compared with the previous guidance, except for potential reversals of previous credit losses which were not allowed under prior guidance. In January 2017, the FASB issued Accounting Standards Update ("ASU") No. 2017-04, Simplifying the Test for Goodwill Impairment. An entity will no longer perform a hypothetical purchase price allocation to measure impairment, eliminating step 2 of the goodwill impairment test. Instead, impairment will be measured using the difference of the carrying amount to the fair value of the reporting unit. The ASU is effective prospectively for annual and interim periods in fiscal year beginning after December 15, 2019, but early adoption is permitted for goodwill impairment tests with measurement dates after January 1, 2017. The Company is not planning on early adoption of this ASU and has not yet quantified any potential impact of the ASU on the Company's financial statements. In March 2017, the FASB issued Accounting Standards Update ("ASU") No. 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20). The amendments in this ASU shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The Company has a large portfolio of callable debt securities purchased at a premium. As such, the Company had already been amortizing the premium to the earliest call date to reduce volatility in earnings by eliminating reporting large realized losses when debt securities are called. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018.
