New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	2. RECENT ACCOUNTING PRONOUNCEMENTS Accounting Standards Adopted in 2019 In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The ASU establishes a right-of-use ("ROU") model that requires a lessee to recognize a ROU lease asset and lease liability on the balance sheet for all leases with a term of longer than 12 months. The FASB has also made available several practical expedients to assist entities with the adoption of ASU 2016-02. Among other things, these practical expedients require no reassessment of whether existing contracts are or contain leases as well as no reassessment of lease classification for current leases. In July 2018, the FASB released ASU 2018-11, "Leases (Topic 842): Targeted Improvements," which adds an additional practical expedient that allows entities to elect not to recast comparative periods presented when transitioning to Topic 842. The Company elected to adopt the practical expedient allowed under ASU 2018-11. During the year ended December 31, 2018, the Company engaged a software vendor to assist in the implementation of ASU 2016-02. The Company adopted ASU 2016-02 effective January 1, 2019 using the modified retrospective approach and recorded a ROU lease asset and corresponding lease liability on the Company's consolidated balance sheet of $55.9 million for its operating leases where it is a lessee. There was no impact to the Company's financial statements for its leases where it is a lessor. As of September 30, 2019, the ROU lease asset and lease liability was $52.6 million and $52.8 million, respectively. See Note 12 - Leases for required disclosures on this new standard. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." ASU 2017-12 was issued to better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The FASB believes that such amendments will: 1) improve the transparency of information about an entity’s risk management activities and 2) simplify the application of hedge accounting. The ASU allows an entity that qualifies for the last-of-layer method a one-time opportunity to reclassify securities from the held-to-maturity category to the available-for-sale category. The Company adopted ASU 2017-12 effective January 1, 2019 and transferred its entire held-to-maturity investment securities portfolio with a fair value of $144.3 million at January 1, 2019 to the available-for-sale portfolio. On the date of adoption, the Company recorded a cumulative effect adjustment related to the unrealized loss on the investment securities transferred, which decreased available-for-sale investments by $4.2 million, increased deferred tax assets by $1.1 million, and decreased opening accumulated other comprehensive income (loss) ("AOCI") by $3.1 million. The ASU did not have a material impact on our current derivative activities. In August 2018, the FASB issued ASU 2018-15, "Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract," which requires an entity in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized implementation costs should be presented in the same line item on the balance sheet as amounts prepaid for the hosted service, if any (generally as an “other asset”). The capitalized costs will be amortized over the term of the hosting arrangement, with the amortization expense being presented in the same income statement line item as the fees paid for the hosted service. ASU 2018-15 is effective for the Company's reporting period beginning January 1, 2020 and early adoption is permitted. The Company early adopted ASU 2018-15 during the second quarter of 2019. The adoption of the ASU did not have a material impact on our consolidated financial statements. Impact of Other Recently Issued Accounting Pronouncements on Future Filings In June 2016, the FASB issued ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," and subsequent amendments to the guidance, ASU 2019-04 in April 2019 and ASU 2019-05 in May 2019. The standard significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren’t measured at fair value through net income. In issuing the standard, the FASB is responding to criticism that today’s “incurred loss” guidance delays the recognition of credit losses on loans, leases, held-to-maturity debt securities, loan commitments, and financial guarantees, and instead provides for a current expected credit loss (“CECL”) approach to determine the allowance for credit losses. CECL requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. In addition, this guidance modifies the accounting treatment for other-than-temporary impairment for available-for-sale debt securities. Organizations will continue to use judgment to determine which loss estimation methods are appropriate for their circumstances. This guidance requires entities to record a cumulative effect adjustment to the consolidated balance sheet as of the beginning of the first reporting period in which the guidance is effective. However, an organization may elect to phase in the regulatory capital impact over a three-year transition period if adoption of the new standard results in a reduction of retained earnings. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with earlier adoption permitted. As such, the Company will implement CECL for the reporting period beginning January 1, 2020. The new guidance will require significant operational changes, particularly in existing processes, data collection and analysis. The Company has formed a steering committee that is responsible for oversight of the Company’s implementation strategy for compliance with provisions of the new standard. The Company has also established a project management governance process to manage the implementation across affected disciplines. To date, the Company has established appropriate loan pools by segment and sub-segment, developed internal loss driver models, and has leveraged a third-party software solution to measure expected losses under CECL. As part of this process, the Company has also engaged an additional third party specializing in economic forecasting to enable it to incorporate reasonable and supportable forecasts in its process. Finally, the Company is developing and enhancing internal controls, having its CECL framework independently validated by a third-party expert, performing parallel runs, and addressing remaining gaps. While the Company is evaluating the full impact of adopting this new guidance, management expects that it will be significantly influenced by its own historical experience, the composition and quality of the Company’s loans, the underlying assumptions embedded in its methodology, as well as economic condition expectations as of the date of adoption. The Company also anticipates significant changes to its reserve calculation processes and procedures and continues to evaluate the potential impact on our consolidated financial statements through sensitivity analysis of underlying assumptions and economic scenarios. In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement." The ASU is part of the FASB's disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information required by generally accepted accounting principles. The ASU modifies disclosure requirements on fair value measurements in Topic 820 and is effective for the Company's reporting period beginning January 1, 2020. Early adoption is permitted. Based on preliminary evaluation, the ASU will not have a material impact on disclosures in our consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, "Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans." Like ASU 2018-13, this ASU is part of the FASB's disclosure framework project. This ASU modifies disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The ASU is effective for the Company's reporting period beginning January 1, 2021. Early adoption is permitted. Based on preliminary evaluation, the ASU will not have a material impact on disclosures in our consolidated financial statements.
