ASU 2016-02 requires lessees to recognize most leases on the balance sheet. The recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee depends on its classification as a finance or operating lease. ASU 2016-02 requires a modified retrospective transition, with a package of practical expedients that entities may elect to apply. In January 2018, Accounting Standards Update No. 2018-01, “Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842” was issued to address concerns about the costs and complexity of complying with the transition provisions of ASU 2016-02. In July 2018, Accounting Standards Update No. 2018-10, “Codification Improvements to Topic 842, Leases” was issued to provide more detailed guidance and additional clarification for implementing ASU 2016-02. Also in July 2018, Accounting Standards Update No. 2018-11, “Targeted Improvements” (“ASU 2018-11”) was issued and allows for an optional transition method in which the provisions of Topic 842 would be applied upon the adoption date and would not have to be retroactively applied to the earliest reporting period presented in the consolidated financial statements. The Corporation used this optional transition method for the adoption of Topic 842. In December 2018, Accounting Standards Update No. 2018-20, “Leases (Topic 842) Narrow-Scope Improvement for Lessors” was issued to address lessors’ concerns about sales taxes and other similar taxes collected from lessees, certain lessor costs, and recognition of variable payments for contracts with lease and non-lease components. These ASUs were effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Management assembled a project team to address the changes pursuant to Topic 842. The project team identified and reviewed all lease agreements in scope of Topic 842. The Corporation rents premises used in business operations under non-cancelable operating leases, which as of December 31, 2018 were not reflected in its Consolidated Balance Sheets. The Corporation has no finance leases.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Corporation adopted Topic 842 “Leases” effective January 1, 2019 and has applied the guidance to all operating leases within the scope of Topic 842 at that date. The Corporation elected to adopt the package of practical expedients, which among other things, does not require reassessment of lease classification. The Corporation recognized </span><span style="font-family:inherit;font-size:10pt;"><span>$28.9 million</span></span><span style="font-family:inherit;font-size:10pt;"> in operating lease right-of-use-assets, </span><span style="font-family:inherit;font-size:10pt;"><span>$30.9 million</span></span><span style="font-family:inherit;font-size:10pt;"> in operating lease liabilities, a reduction in rent-related liabilities of </span><span style="font-family:inherit;font-size:10pt;"><span>$2.9 million</span></span><span style="font-family:inherit;font-size:10pt;">, a reduction of net deferred tax assets of </span><span style="font-family:inherit;font-size:10pt;"><span>$222 thousand</span></span><span style="font-family:inherit;font-size:10pt;"> and a cumulative effect adjustment (net of taxes) that increased beginning retained earnings by </span><span style="font-family:inherit;font-size:10pt;"><span>$722 thousand</span></span><span style="font-family:inherit;font-size:10pt;"> in the Consolidated Balance Sheets. The cumulative effect adjustment represented the recognition of unamortized deferred gains associated with two leases. There was no change to the timing in recognition of operating lease rent expense on the Corporation’s consolidated financial statements associated with our leases.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In March 2019, Accounting Standards Update No. 2019-01, “Leases (Topic 842) Codification Improvements” (“ASU 2019-01”) was issued to address lessors’ concerns about determining fair value of underlying leased assets and presentation issues in the statement of cash flows for sales-type and direct financing leases. ASU 2019-01 also clarified for both lessees and lessors that transition disclosures related to Topic 250 were not required for annual periods are also not required for interim periods. ASU 2019-01 was effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2019, with early adoption permitted. The Corporation early adopted this ASU 2019-01 effective January 1, 2019 and it did not have a material impact on the Corporation’s consolidated financial statements.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;text-decoration:underline;">Derivatives and Hedging - Topic 815</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Accounting Standards Update No. 2017-12, “Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”), was issued in August 2017 to better align financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 was effective for fiscal years beginning after December 15, 2018, with early adoption, including adoption in an interim period, permitted. In addition, ASU 2017-12 also permitted the reclassification of eligible securities from the held to maturity classification to the available for sale classification. The Corporation adopted the provisions of ASU 2017-12 on January 1, 2019 using a modified retrospective transition method. As permitted by ASU 2017-12, qualifying debt securities classified as held to maturity with an amortized cost of </span><span style="font-family:inherit;font-size:10pt;"><span>$10.4 million</span></span><span style="font-family:inherit;font-size:10pt;"> and a fair value of </span><span style="font-family:inherit;font-size:10pt;"><span>$10.3 million</span></span><span style="font-family:inherit;font-size:10pt;"> were reclassified to available for sale upon the adoption date. An unrealized loss of </span><span style="font-family:inherit;font-size:10pt;"><span>$75 thousand</span></span><span style="font-family:inherit;font-size:10pt;"> (net of taxes) was recognized in the accumulated other comprehensive income component of shareholders’ equity at the date of adoption. The adoption of ASU 2017-12 did not have a material impact on the Corporation’s consolidated financial statements.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Accounting Standards Update No. 2018-16, “Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes” (“ASU 2018-16”), was issued in October 2018 to permit the use of the Overnight Index Swap rate based on the Secured Overnight Financing Rate as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to existing benchmark interest rates that are currently used for hedge accounting. ASU 2018-16 was effective for fiscal years beginning after December 15, 2018, and interim periods with those fiscal years. The provisions required prospective application for qualifying new or re-designated hedging relationships entered into on or after the date of adoption. The Corporation adopted the provisions of ASU 2018-16 on January 1, 2019 and it did not have a material impact on the Corporation’s consolidated financial statements.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-weight:bold;">Accounting Standards Pending Adoption</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;text-decoration:underline;">Financial Instruments - Credit Losses - Topic 326</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Accounting Standards Update No. 2016-13, “Financial Instruments - Credit Losses” (“ASU 2016-13”), was issued in June 2016. ASU 2016-13 requires the measurement of all expected credit losses for financial assets measured at amortized cost, as well as off-balance sheet credit exposures at the reporting date. The measurement is based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available for sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 provides for a modified retrospective transition, resulting in a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is effective, except for debt securities for which an other-than-temporary impairment has previously been recognized. For these debt securities, a prospective transition approach will be adopted in order to maintain the same amortized cost prior to and subsequent to the effective date of ASU 2016-13. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2019. The </span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Corporation will adopt ASU 2016-13 on January 1, 2020 and continues to evaluate the effect that this ASU will have on the consolidated financial statements and disclosures.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In April 2019, Accounting Standards Update No. 2019-04, “Codification Improvements to Topic 326 Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments” (“ASU 2019-04”) was issued to provide additional clarification on the scope and disclosure requirements of Topic 326. ASU 2019-04 includes provisions related to accounting policy elections that can be made by the entity related to accrued interest receivable and expected prepayments on financial assets, the inclusion of recoveries in estimating the allowance for credit losses (“ACL”) and consideration of contract extension and renewals when determining the contractual term. This ASU also provides clarification on the tabular vintage disclosures related to line-of-credit arrangements that convert term loans. In May 2019, Accounting Standards Update No. 2019-05, “Financial Instruments - Credit Losses (Topic 326); Targeted Transition Relief” (“ASU 2019-05”) was issued to allow an entity to make an irrevocable fair value option election on instruments within the scope of Topic 326 that are measured at amortized cost, except for held to maturity debt securities. This election can be applied on an instrument-by-instrument basis upon the adoption of Topic 326. The effective dates of ASU 2019-04 and ASU 2019-05 are the same as the effective date of ASU 2016-13.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">To prepare for the adoption of ASU 2016-13 and related updates, the Corporation assembled a cross-functional project team that meets regularly to address the additional data requirements necessary, to determine the approach for implementation and to identify new internal controls over enhanced accounting processes that will be put into place for estimating the ACL. This has included assessing the adequacy of existing loan and loss data, as well as validating models for default and loss estimates. The Corporation has substantially completed the development of its Topic 326 compliant methodology. The new methodology will include models that contain additional assumptions used to calculate credit losses over the estimated life of financial assets and off-balance sheet credit exposures and will include the impact of forecasted economic conditions. For available for sale debt securities with unrealized losses, credit losses will be recognized as an allowance rather than a reduction in the amortized cost of the securities. As a result, improvements to estimated credit losses will be recognized immediately in earnings rather than as interest income over time. Based on the credit quality of our existing available for sale debt securities portfolio, the Corporation does not expect the adoption of ASU 2016-13, as it relates to debt securities, to be significant.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The project team continues to review the output from “trial” runs and is in the process of assessing qualitative factors. The Corporation is also updating its accounting processes and policies and internal controls associated with the Topic 326 compliant methodology.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Corporation plans to finalize its Topic 326 compliant methodology, accounting policies and internal controls in the fourth quarter of 2019. Upon adoption, an increase to the ACL will be recorded with a corresponding one-time cumulative-effect adjustment to retained earnings. The FDIC approved a final rule that provides banking organizations the option to phase in over a three-year period the day-one adverse effects on regulatory capital that may result from the adoption of the new accounting standard. The Corporation is planning on adopting the capital transition relief over the permissible three-year period.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;text-decoration:underline;">Fair Value Measurement - Topic 820</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Accounting Standards Update No. 2018-13, “Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”), was issued in August 2018 to modify the disclosure requirements related to fair value. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted, including adoption in an interim period. Certain provisions under ASU 2018-13 require prospective application, while other provisions require retrospective application to all periods presented in the consolidated financial statements upon adoption.

ASU 2018-14 is effective for fiscal years ending after December 15, 2020, with early adoption permitted. The provisions under ASU 2018-14 are required to be applied retrospectively.
