The amendments included in this ASU change guidance on the amortization period of premiums on certain purchased callable debt securities. Specifically, the amendments shorten the premium amortization period to the earliest call date. The amendments in ASU 2017-08 are effective for fiscal years and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The Company early adopted the amendments of ASU 2017-08 during the current quarter. The impact of the adoption of ASU 2017-08 to current period net income and opening retained earnings was not material.</font></div><div style="line-height:120%;padding-top:12px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In January 2017, the FASB issued ASU 2017-04, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Simplifying the Test for Goodwill Impairment</font><font style="font-family:inherit;font-size:10pt;">. The amendments in this are intended to reduce the cost and complexity of the goodwill impairment test by eliminating the second step of the goodwill impairment test. An entity will apply a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The new guidance does not amend the optional qualitative assessment of goodwill impairment. The amendments in ASU 2017-04 are effective for annual or interim periods beginning after December 15, 2019. Early adoption is permitted. The Company does not expect the impact to its Consolidated Financial Statements to be material.</font></div><div style="line-height:120%;padding-top:12px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In June 2016, the FASB issued ASU 2016-13, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Measurement of Credit Losses on Financial Instruments</font><font style="font-family:inherit;font-size:10pt;">. The amendments included in this ASU require an entity to reflect its current estimate of all expected credit losses for assets held at an amortized cost basis. For available for sale debt securities, credit losses will be measured in a manner similar to current GAAP, however, this ASU will require that credit losses be presented as an allowance rather than as a write-down. The amendments in ASU 2016-13 are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and are required to be adopted through a modified retrospective approach, with a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is effective.</font></div><div style="line-height:120%;padding-top:12px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Currently, the Company cannot reasonably estimate the impact that adoption of ASU 2016-13 will have on its Consolidated Financial Statements; however, the impact may be significant. That assessment is based upon the fact that, unlike the incurred loss models in existing GAAP, the current expected credit loss (“CECL”) model in ASU 2016-13 does not specify a threshold for the recognition of an impairment allowance. Rather, the Company will recognize an impairment allowance equal to its estimate of lifetime expected credit losses, adjusted for prepayments, for in-scope financial instruments as of the end of the reporting period. Accordingly, the impairment allowance measured under the CECL model could increase significantly from the impairment allowance measured under the Company’s existing incurred loss model. Significant CECL implementation matters to be addressed by the Company include selecting loss estimation methodologies, identifying, sourcing and storing data, addressing data gaps, defining a reasonable and supportable forecast period, selecting historical loss information which will be reverted to, documenting the CECL estimation process, assessing the impact to internal controls over financial reporting, capital planning and seeking process approval from audit and regulatory stakeholders.</font></div><div style="line-height:120%;padding-top:12px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In March 2016, the FASB issued ASU 2016-09, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Improvements to Employee Share-Based Payment Accounting</font><font style="font-family:inherit;font-size:10pt;">. The amendments included in this ASU simplify several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company adopted the amendments of ASU 2016-09 in the current quarter. Adoption of amended forfeiture guidance resulted in an opening period adjustment decreasing retained earnings </font><font style="font-family:inherit;font-size:10pt;">$117 thousand</font><font style="font-family:inherit;font-size:10pt;"> and increasing common stock </font><font style="font-family:inherit;font-size:10pt;">$184 thousand</font><font style="font-family:inherit;font-size:10pt;">. Adoption of the amended excess tax benefit guidance resulted in a current period income tax benefit of </font><font style="font-family:inherit;font-size:10pt;">$1.2 million</font><font style="font-family:inherit;font-size:10pt;"> or </font><font style="font-family:inherit;font-size:10pt;">$0.02</font><font style="font-family:inherit;font-size:10pt;"> per diluted common share.</font></div><div style="line-height:120%;padding-top:12px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In February 2016, the FASB issued ASU 2016-02, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Leases</font><font style="font-family:inherit;font-size:10pt;">. The amendments included in this ASU create a new accounting model for both lessees and lessors. The new guidance requires lessees to recognize lease liabilities, initially measured as the present value of future lease payments, and corresponding right-of-use assets for all leases with lease terms greater than 12 months. This model differs from the current lease accounting model, which does not require such lease liabilities and corresponding right-of-use assets to be recorded for operating leases. The amendments in ASU 2016-02 must be adopted using the modified retrospective approach and will be effective for the first interim or annual period beginning after December 15, 2018. Early adoption is permitted. During 2016, the Company implemented a new lease administration application that allows the Company to readily measure future lease payment streams, which is an important component of the new lease accounting model. Significant implementation matters to be addressed by the Company include selecting either a third-party lease accounting application or internally-developing such an application, assessing the impact to its Consolidated Financial Statements and internal controls over financial reporting and documenting the new lease accounting process. See Note 17, “Commitments and Contingent Liabilities” to our 2016 Form 10-K, for more information regarding the minimum future payments related to our operating leases.</font></div></div>
