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;">The project team that was assembled to address the changes pursuant to Topic 842 identified and reviewed all in scope lease agreements. 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. Upon adoption, 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 in the Corporation’s consolidated financial statements associated with 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, </span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">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 expected lifetime 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 Corporation will adopt ASU 2016-13, including the subsequent ASUs issued to clarify Topic 326 (“Topic 326”), on January 1, 2020.</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” was issued to provide additional clarification on the scope and disclosure requirements of Topic 326. This ASU 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 November 2019, Accounting Standards Update No. 2019-11, “Codification Improvements to Topic 326, Financial Instruments-Credit Losses” was issued to further additional clarification on the adoption of Topic 326. The effective dates of these ASUs 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;">The Corporation assembled a cross-functional project team that met regularly to address the additional data requirements, to determine the approach for implementation and to identify new internal controls over enhanced accounting processes for estimating the ACL. This included assessing the adequacy of existing loan and loss data, as well as assessing models for default and loss estimates.</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 has completed the development of its ACL methodology. To estimate the ACL for loans and off-balance sheet credit exposures, such as unfunded loan commitments, the Corporation will utilize a discounted cash flow model that contains additional assumptions 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. The estimate is expected to include </span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">a one-year reasonable and supportable forecast period and thereafter a one-year reversion period to the historical mean of its macroeconomic assumption. The estimate will also include qualitative factors that may not be reflected in quantitatively derived results to ensure that the ACL reflects a reasonable estimate of current expected credit losses.</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;">Based on the credit quality of our existing available for sale debt securities portfolio, which primarily consists of obligations of U.S. government agency and U.S. government-sponsored enterprise securities, including mortgage-backed securities, the Corporation does not expect the adoption of ASU 2016-13, as it relates to debt securities, to be significant. 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.</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 completed limited “trial” runs and analytical reviews through the year ended December 31, 2019.
