The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The amendments also require the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, including reasonably certain renewal periods. </font><font style="font-family:inherit;font-size:10pt;"> </font><font style="font-family:inherit;font-size:10pt;">The amendments in ASU 2018-15 are effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The Company is assessing the impact that this guidance will have on its Consolidated Financial Statements.</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 August 2016, the FASB issued ASU 2016-15, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Classification of Certain Cash Receipts and Cash Payments</font><font style="font-family:inherit;font-size:10pt;">. The amendments in this ASU provide specific guidance on several statement of cash flow classification issues to reduce diversity in practice. The amendments in ASU 2016-15 are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The Company has reclassified items in the Statement of Cash Flows for the </font><font style="font-family:inherit;font-size:10pt;">nine</font><font style="font-family:inherit;font-size:10pt;"> months ended </font><font style="font-family:inherit;font-size:10pt;">September 30, 2017</font><font style="font-family:inherit;font-size:10pt;"> to conform with its current presentation based on its adoption of ASU 2016-15.</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. The Company has engaged a third-party vendor to assist in the CECL calculation and has developed an internal governance framework to oversee the CECL implementation. Other significant CECL implementation matters being 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 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. The FASB subsequently issued ASU 2018-11, which allows for an additional (optional) transition method. Early adoption is permitted. During 2017, the Company selected a third-party lease accounting application to assist in the implementation of this new guidance. Significant implementation matters to be addressed by the Company include assessing the impact to our internal controls over financial reporting and documenting the new lease accounting process. At September 30, 2018 the Company’s estimate of right-of-use assets and lease liabilities that would be recorded on its January 1, 2019 Consolidated Balance Sheet upon adoption of ASU 2016-02 was between </font><font style="font-family:inherit;font-size:10pt;">$40.0 million</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">$50.0 million</font><font style="font-family:inherit;font-size:10pt;">. This estimate may change depending on the Company’s lease activity. Additionally, the Company expects to recognize a cumulative effect adjustment upon adoption to increase the beginning balance of retained earnings as of January 1, 2019 for any remaining deferred gains on sale-leaseback transactions which occurred prior to the date of adoption. The Company had </font><font style="font-family:inherit;font-size:10pt;">$1.0 million</font><font style="font-family:inherit;font-size:10pt;"> of deferred gains on sale-leaseback transactions as of September 30, 2018. We do not expect a material impact to our Consolidated Statement of Income as a result of this ASU. </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 2016, the FASB issued ASU 2016-01, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Recognition and Measurement of Financial Assets and Financial Liabilities</font><font style="font-family:inherit;font-size:10pt;">. The amendments in ASU 2016-01 require all equity investments to be measured at fair value with changes in the fair value recognized through net income. The amendments in ASU 2016-01 also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this update eliminate the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. The amendments in ASU 2016-01 are effective for the first interim or annual period beginning after December 15, 2017. The Company adopted the amendments of ASU 2016-01 effective January 1, 2018 and recorded a cumulative effect adjustment of </font><font style="font-family:inherit;font-size:10pt;">$157 thousand</font><font style="font-family:inherit;font-size:10pt;"> to retained earnings related to the unrealized holding losses on equity securities with readily determinable fair value included in accumulated other comprehensive loss. The Company also added a separate line item on the Consolidated Balance Sheet for equity securities at fair value and reclassified amounts previously included in securities available for sale at fair value to conform to current period presentation. In addition, as required by the ASU, the fair value disclosure for loans is computed using an exit price notion and deposits with no stated maturity are no longer included in the fair value disclosures in </font><a style="font-family:inherit;font-size:10pt;" href="#sAB1B3D2C9437580BA597FFAF26D1D379"><font style="font-family:inherit;font-size:10pt;">Note 15, “Fair Value Accounting and Measurement.”</font></a></div><div style="line-height:120%;padding-top:12px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In May 2014, the FASB issued ASU 2014-09, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Revenue from Contracts with Customers</font><font style="font-family:inherit;font-size:10pt;">, which provides revenue recognition guidance that is intended to create greater consistency with respect to how and when revenue from contracts with customers is shown in the income statement. The guidance requires that revenue from contracts with customers be recognized when transfer of control over goods or services is passed to customers in the amount of consideration expected to be received. Subsequent Accounting Standard Updates have been issued clarifying the original pronouncement (ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20). The majority of the Company’s revenue is comprised of interest income from financial assets, which is specifically outside the scope of ASU 2014-09.</font></div><div style="line-height:120%;padding-top:12px;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">On January 1, 2018, we adopted the accounting guidance in ASU 2014-09 and all the related amendments (“Topic 606”) using the modified retrospective method for all contracts that have not been completed (i.e. open contracts). Therefore, the comparative information has not been adjusted and continues to be reported under Topic 605. There was no cumulative effect adjustment as of January 1, 2018, and there were no material changes to the timing or amount of revenue recognized for the nine months ended September 30, 2018; however, additional disclosures were incorporated in the footnotes upon adoption. See </font><a style="font-family:inherit;font-size:10pt;" href="#sF784076ECBA657FAB2600BE08037C65C"><font style="font-family:inherit;font-size:10pt;">Note 17, “Revenue from Contracts with Customers,”</font></a><font style="font-family:inherit;font-size:10pt;"> for more information.</font></div></div>
