New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Accounting Standards Adopted in 2019 Leases - Topic 842 Accounting Standards Update No. 2016-02, “Leases” (“ASU 2016-02”), was issued in February 2016 and provides revised guidance related to the accounting and reporting of leases. 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. 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. 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 $28.9 million in operating lease right-of-use-assets, $30.9 million in operating lease liabilities, a reduction in rent-related liabilities of $2.9 million, a reduction of net deferred tax assets of $222 thousand and a cumulative effect adjustment (net of taxes) that increased beginning retained earnings by $722 thousand 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. 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. Derivatives and Hedging - Topic 815 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 $10.4 million and a fair value of $10.3 million were reclassified to available for sale upon the adoption date. An unrealized loss of $75 thousand (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. 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. Accounting Standards Pending Adoption Financial Instruments - Credit Losses - Topic 326 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 held at the reporting date 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, with early adoption permitted in 2019. The Corporation will adopt ASU 2016-03 on January 1, 2020 and is currently evaluating the effect that this ASU will have on the consolidated financial statements and disclosures. Management has assembled a 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 processes that will be put into place for estimating the allowance under ASU 2016-13. This has included assessing the adequacy of existing loan and loss data, as well as developing models for default and loss estimates. The Corporation expects to continue the validation of models, the development of accounting policies and internal controls and the execution of “trial” or “parallel” runs of its ASU 2016-13 compliant methodology throughout 2019. Fair Value Measurement - Topic 820 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. The adoption of ASU 2018-13 is not expected to have a material impact on the Corporation’s consolidated financial statements. Compensation - Retirement Benefits - Topic 715 Accounting Standards Update No. 2018-14, “Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans” (“ASU 2018-14”), was issued in August 2018 to modify the disclosure requirements associated with defined benefit pension plans and other postretirement plans. 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. The adoption of ASU 2018-14 is not expected to have a material impact on the Corporation’s consolidated financial statements. Intangibles - Goodwill and Other - Internal-Use Software - Topic 350 Accounting Standards Update No. 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract” (“ASU 2018-15”), was issued in August 2018 to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with those requirements that currently exist in GAAP for capitalizing implementation costs incurred to develop or obtain internal-use software. Implementation costs would either be capitalized or expensed as incurred depending on the project stage. All costs in the preliminary and post-implementation project stages are expensed as incurred, while certain costs within the application development stage are capitalized. The provisions under ASU 2018-15 can either be applied retrospectively or prospectively. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted, including adoption in an interim period. The adoption of ASU 2018-15 is not expected to have a material impact on the Corporation’s consolidated financial statements.
