Specifically, this update shortens the amortization period of certain purchased callable debt securities to the earliest call date. ASU 2017-08 is effective for the Company beginning with the first quarter of 2019. Early adoption is permitted. The Company does not anticipate significant impact from this guidance. *Accounting Standards Update No.* *2017-05.* In February 2017, the FASB issued Accounting Standards Update No. 2017-05 (“ASU 2017-05”), Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20), which clarifies the scope of asset derecognition guidance and accounting for partial sales of nonfinancial assets. In addition, ASU 2017-15 eliminates the exception in the financial asset guidance for transfers of investments including equity method investments in real estate entities and supersedes the guidance in the Exchanges of a Nonfinancial Asset for a Noncontrolling Ownership Interest subsection (Topic 845). ASU 2017-05 is effective for the Company beginning with the first quarter of 2018. The Company does not anticipate significant impact from this guidance. *Accounting Standards Update No.* *2017-03.* In January 2017, the FASB issued Accounting Standards Update No. 2017-03 (“ASU 2017-03”), Accounting Changes and Error Corrections (Topic 250) and Investments—Equity Method and Joint Ventures (Topic 323), which adds and amends SEC paragraphs pursuant to SEC Staff Announcements at the September 22, 2016 and November 17, 2016 Emerging Issues Task Force meetings. The announcement made at the September 22, 2016 meeting provides the SEC staff view on the disclosure of the impact that recently issued accounting standards will have on a public entity’s financial statements when the standards are adopted in a future period. This announcement applies to ASU 2014-09, Revenue from Contracts with Customers (Topic 606); ASU 2016-02, Leases (Topic 842); ASU 2016-13, Financial Instruments—Credit Losses (Topic 326) and any subsequent amendments to guidance in the ASUs that are issued prior to the adoption of the aforementioned ASUs. *Accounting Standards Update No.* *2017-01.* In January 2017, the FASB issued Accounting Standards Update No. 2017-01 (“ASU 2017-01”), Business Combinations (Topic 805), which clarifies the definition of a business and provides a screen to determine when an integrated set of assets and activities is not a business. If the screen is not met, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output to be considered a business. ASU 2017-01 is effective for the Company beginning with the first quarter of 2018. Early adoption is permitted under certain circumstances. When adopted, this guidance will impact how the Company determines whether a transaction should be accounted for as an acquisition (or disposal) of an asset or a business. The Company elected to adopt this standard in the fourth quarter of 2017. Accounting Standards to be Adopted in Fiscal Year 2018 In February 2018, the FASB issued Accounting Standards Update No. 2018-02 (“ASU 2018-02”), Income Statement – Reporting Comprehensive Income (Topic 220), primarily allowing a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017. Early adoption is permitted. The Company elected to early adopt this standard in the first quarter of 2018, which has no impact to the Company’s financial position. In January 2016, the FASB issued Accounting Standards Update No. 2016-01 (“ASU 2016-01”), Financial Instruments – Overall (Subtopic 825-10), primarily requiring all equity investments other than those accounted for under the equity method of accounting or those that result in consolidation of the investee to be measured at fair value with changes in the fair value recognized through net income. The application of ASU 2016-01 could cause the Company to experience significant volatility in earnings. Under current accounting policy, the Company recognizes unrealized holding gains and losses on available-for-sale equity securities in stockholders’ equity as a component of accumulated other comprehensive income. In the year of adoption, the unrealized holding gains and losses of available-for-sale equity securities reported in accumulated other comprehensive income at December 31, 2017 will be reclassified to beginning retained income. Any subsequent changes in fair value will be recognized in the consolidated statement of income. In addition, the classification of the Company’s equity securities with readily determinable fair values as “available-for-sale” in the consolidated balance sheet and related disclosures will be eliminated. In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606). The core principle of the guidance 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. ASU 2014-09 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. ASU 2014-09 also amends the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are not in a contract with a customer to be consistent with the guidance in this ASU. ASU 2014-09 permits two methods of adoption: a full retrospective method or a modified retrospective method. The Company has identified and reviewed impacted revenue generating activities in accordance with the five-step revenue recognition model specified by this standard. The Company elects to use a modified retrospective method for transition to the new revenue recognition standard. Based on the Company’s assessment, the impact will be limited to the related disclosures of certain revenue generating activities as its primary source of revenue from insurance premiums is not within the scope of this new standard.
