New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Authoritative Accounting Guidance	NEW AUTHORITATIVE ACCOUNTING GUIDANCE Financial Accounting Standards Board (the “FASB”) Accounting Standards Update (the “ASU”) 2018-15 “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” In August 2018, the FASB issued ASU 2018-15, which amends ASC 350-402 to address a customer’s accounting for implementation costs incurred in a cloud computing arrangement (CCA) that is a service contract. ASU 2018-15 aligns the accounting for costs incurred to implement a CCA that is a service arrangement with the guidance on capitalizing costs associated with developing or obtaining internal-use software. Specifically, the ASU amends ASC 350 to include in its scope implementation costs of a CCA that is a service contract and clarifies that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized in a CCA that is considered a service contract. The amendments are effective for public business entities for annual periods beginning after December 15, 2019, including interim periods within those annual periods, with early adoption being permitted. The Company is currently evaluating the new guidance and has not yet determined the impact this standard may have on its consolidated financial statements. FASB ASU 2018-13 “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement.” In August 2018, the FASB issued ASU 2018-13, which changes the fair value measurement disclosure requirements of ASC 820. The amendments in this ASU are the result of a broader disclosure project called FASB Concepts Statement, Conceptual Framework for Financial Reporting — Chapter 8: Notes to Financial Statements, which the Board finalized on August 28, 2018. The Board used the guidance in the Concepts Statement, including consideration of costs and benefits, to improve the effectiveness of ASC 820’s disclosure requirements. The amendments in this update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this update. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this update and delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the new guidance and has not yet determined the impact this standard may have on its consolidated financial statements. FASB ASU 2017-08 “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities.” In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20)” which shortens the amortization period of certain callable debt securities held at a premium to the earliest call date. The amendments are effective for public business entities for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption being permitted. The Company has evaluated the new guidance and does not expect it to have a material impact on the Company's consolidated financial statements. At December 31, 2018, the book value of callable bonds purchased at a premium totaled $22.0 million, and the amount of unamortized premium remaining on these securities was $0.7 million. FASB ASU 2016-13 “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” In June 2016, the FASB issued ASU 2016-13, “Financial Instruments (Topic 326)” which changes the methodology for evaluating impairment of most financial instruments. The ASU replaces the currently used incurred loss model with a forward-looking expected loss model, which will generally result in a more timely recognition of losses. The guidance becomes effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company has formed an implementation team that includes members of accounting, credit, and loan operations to review the requirements of ASU 2016-13, and has contracted with a software provider to aid in implementation. The Company has not yet determined the impact this standard may have on its financial statements. FASB ASU 2016-02 “Leases (Topic 842).” In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” which requires organizations that lease assets (“lessees”) to recognize the assets and liabilities for the rights and obligations created by leases with terms of more than 12 months. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee remains dependent on its classification as a finance or operating lease. The criteria for determining whether a lease is a finance or operating lease has not been significantly changed by this ASU. The ASU also requires additional disclosure of the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. The guidance becomes effective for periods beginning after December 15, 2018, including interim periods therein. Early adoption will be permitted. In July 2018, the FASB issued ASU 2018-11 “Leases (Topic 842): Targeted Improvements” to provide entities with relief from the costs of implementing certain aspects of the new leasing standard. Specifically, under the amendments in ASU 2018-11 (1) entities may elect not to recast the comparative periods presented when transitioning to ASC 842 (2) lessors may elect not to separate lease and nonlease components when certain conditions are met. The Company has formed a lease implementation team that includes members of accounting, facilities and operations to review lease contracts and the requirements of ASU 2016-02 and ASU 2018-11. The Company intends to utilize the optional transition method at the adoption date of January 1, 2019. In 2019, the Company will record approximately $15 million on the balance sheet for right-to-use assets and lease liabilities related to operating leases.
