New Accounting Pronouncements, Policy	*Recently Adopted Accounting Standards* In October 2016, the Financial Accounting Standards Board (“FASB”) issued guidance that amends the consolidation analysis for a reporting entity that is the single decision maker of a variable interest entity. The amendments in this guidance require the decision maker’s evaluation of its interests held through related parties that are under common control on a proportionate basis rather than in their entirety when determining whether it is the primary beneficiary of that variable interest entity. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements. In November 2016, the FASB issued guidance requiring entities to show the changes in the total cash, cash equivalents, restricted cash and restricted cash equivalent in the statement of cash flows. The amendments in this guidance should be applied retrospectively and is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The adoption of this guidance is not expected to have a material effect on the Company’s consolidated financial statements. In October 2016, the FASB issued guidance requiring an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments in this guidance should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption and are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods. The adoption of this guidance is not expected to have a material effect on the Company’s consolidated financial statements. In August 2016, the FASB issued guidance that changes how certain cash receipts and cash payments are presented and classified in the cash flows statement. The amendments in this Update are effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material effect on the Company’s consolidated financial statements. In June 2016, the FASB issued guidance requiring financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. An allowance for credit losses will be deducted from the amortized cost basis to present the net carrying value at the amount expected to be collected with changes in the allowance recorded in earnings. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses rather than the currently applied U.S. GAAP method of taking a permanent impairment of the security, which would be limited to the amount by which fair value is below the amortized cost. Certain existing requirements used to evaluate credit losses have been removed. For public entities that are SEC filers, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those years. Early adoption is permitted for fiscal years beginning after December 15, 2018. The amendments in this guidance should be applied through a cumulative effect adjustment to retained earnings upon adoption as of the beginning of the first reporting period in which the guidance is effective. Management is evaluating the requirements and potential impact that the adoption of this guidance will have on the Company’s consolidated financial statements. In February 2016, the FASB issued guidance that requires lessees to recognize the assets and liabilities that arise from leases, including operating leases, on the statement of financial position. The amendments in this guidance are effective for fiscal years beginning after December 31, 2018, including interim periods within those fiscal years, using a modified retrospective approach. The adoption of this guidance is not expected to have a material effect on the Company’s consolidated financial statements. In January 2016, the FASB issued guidance that eliminates the requirement to classify equity securities with readily determinable fair values as trading or available-for-sale. The guidance requires equity securities, other than those that result in consolidation or are accounted for under the equity method, (including other ownership interests, such as partnerships, unincorporated joint ventures, and limited liability companies) to be measured at fair value with changes in the fair value recognized through net income, simplifies the impairment assessment of equity securities without readily determinable fair values and requires changes in disclosure requirements. For public entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted in certain circumstances. The amendments in this Update should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption of the guidance. The adoption of this guidance is not expected to have a material effect on the Company’s Consolidated Balance Sheet or IHC’s stockholders’ equity. In May 2014, the FASB issued revenue recognition guidance for entities that either enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards such as insurance contracts or lease contracts. The amendment provides specific steps that an entity should apply in order to achieve its main objective which is recognizing 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. In 2016, additional guidance and technical corrections were issued to clarify certain aspects of the implementation guidance and to clarify the identification of performance obligations. In August 2015, the effective date of this guidance has been deferred. For public entities, this guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and requires one of two specified retrospective methods of application. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company anticipates that any impact will only relate to contracts with customers outside the scope of Accounting Standards Codification Topic 944, Financial Services - Insurance. Our administrative and other service contracts that will be subject to the amendments in this Update are recorded in the Fee Income line item of the Condensed Consolidated Statement of Income and represents approximately 6% of our consolidated revenues for the six months ended March 31, 2017. Management is still in the process of evaluating the impact that the adoption of this guidance will have on the Company’s consolidated financial statements and the method of adoption that we will ultimately choose.
