New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED	NEW ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED In May 2014, the Financial Accounting Standards Board (FASB) updated its guidance related to the Revenue from Contracts with Customers Topic 606 of the Accounting Standards Codification^TM (Codification or ASC). The objective of this update (and other related following updates) is to improve the reporting of revenue by providing a more robust framework for addressing revenue issues, and improved disclosure requirements. Current revenue recognition guidance in U.S. GAAP is comprised of broad revenue recognition concepts together with numerous revenue requirements for particular industries or transactions, which sometimes result in different accounting for economically similar transactions. This guidance is to be applied retrospectively to annual and interim reporting periods beginning after December 15, 2017, with early adoption permitted as of the original effective date (annual and interim reporting periods beginning after December 15, 2016). The Company will adopt this guidance during the first quarter of 2018. Since premium revenue from insurance contracts is excluded, the Company has only minimal revenue items that are covered by this guidance. The largest revenue item, outside of premium income, is commission income on excess and surplus lines business marketed by EMC Underwriters, LLC, which is included in "Other income" in the consolidated statements of income. Applying this new revenue recognition guidance to commission income produces no material difference compared to that recognized under current practices, as the commission income is typically recognized in full at the time the policy is issued, which is when substantially all of the performance obligation is performed. This guidance will have no impact on the consolidated financial condition or operating results of the Company. In January 2016, the FASB updated its guidance related to the Financial Instruments-Overall Subtopic 825-10 of the ASC. The objective of this update is to enhance the reporting model for financial instruments to provide financial statement users with more decision-useful information. The major change in reporting from this update that will impact the Company is a requirement that equity investments (excluding those accounted for under the equity method of accounting or those that are consolidated) be measured at fair value, with changes in fair value recognized in net income. While all of the Company's equity investments are already measured at fair value (with the exception of those that are consolidated and those that are accounted for under the equity method of accounting), the Company currently classifies all of its investments in equity securities as available-for-sale, and as such, the changes in fair value are currently recognized in other comprehensive income rather than net income. This guidance is to be applied to annual and interim reporting periods beginning after December 15, 2017, with recognition of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. Early adoption is not permitted. The Company will adopt this guidance during the first quarter of 2018. Adoption is not expected to impact consolidated stockholders' equity, but is expected to introduce a material amount of volatility to the Company's consolidated net income. In February 2016, the FASB issued updated guidance in Leases Topic 842 of the ASC, which supersedes the guidance in Leases Topic 840 of the ASC. The objective of this update is to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet, and disclosure of key information about leasing arrangements. This guidance is effective for interim and annual periods beginning after December 15, 2018, and is to be applied using a modified retrospective approach. Early adoption is permitted. The Company will adopt this guidance during the first quarter of 2019. Management continues to research this guidance, which thus far has lead management to a preliminary determination that lease costs allocated to the Company through the pooling and quota share agreements can not be attributed to a specified asset, and therefore do not meet the definition of a leased asset contained in the guidance. As a result, adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition or net income. In June 2016, the FASB issued updated guidance in Financial Instruments-Credit Losses Topic 326 of the ASC. The objective of this update is to provide information about expected credit losses on financial instruments and other commitments to extend credit. Specifically, this updated guidance replaces the current incurred loss impairment methodology which delays recognition of a loss until it is probable a loss has been incurred, with a methodology that reflects expected credit losses considering a broader range of reasonable and supportable information. This guidance covers financial assets that are not accounted for at fair value through net income, thus will not be applicable to the Company's equity investments upon implementation of the updated guidance described above for the Financial Instruments-Overall Subtopic 825-10. This guidance is effective for interim and annual periods beginning after December 15, 2019, and is to be applied with a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (modified-retrospective approach). Early adoption is permitted, but only to fiscal years beginning after December 15, 2018. The Company will adopt this guidance during the first quarter of 2020. The Company is currently evaluating the impact this guidance will have on the Company's consolidated financial condition and net income. In March 2017, the FASB issued updated guidance in Compensation-Retirement Benefits Topic 715 of the ASC. The objective of this update is to improve the presentation of net periodic pension and postretirement benefit costs by disaggregating the components of these expenses (disclosing the service cost component separately from the other components) for income statement reporting. Also included in this update is a prohibition against including components of the net periodic pension and postretirement benefit costs, other than the service cost component, in any capitalized assets. This guidance is effective for interim and annual periods beginning after December 15, 2017. The portion of the guidance related to the income statement display of net periodic pension and postretirement benefit costs is to be applied retrospectively, while the prohibition against including these costs, other than the service cost component, in capitalized assets is to be applied prospectively. Early adoption is permitted. The Company will adopt this guidance during the first quarter of 2018. Adoption will not impact consolidated stockholders' equity initially; however, the prohibition against including components of the net periodic pension and postretirement benefit costs, other than the service cost component, in capitalized assets is expected to result in a relatively small change in the deferred policy acquisition cost asset starting March 31, 2018, which is expected to have an immaterial impact, net of tax, on consolidated stockholders' equity and net income from that which would otherwise have been reported.
