Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Risks and Uncertainties Basis of Presentation In the opinion of the Company, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the consolidated financial position of the Company as of March 31, 2020, the consolidated results of operations for the three months ended March 31, 2020 and 2019, and the consolidated cash flows for the three months ended March 31, 2020 and 2019. All such adjustments were of a normal, recurring nature. Reference is made to the 2019 Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) for a discussion of accounting policies and other relevant information with respect to the financial statements. The results of operations for the periods ended March 31, 2020 and 2019 are not necessarily indicative of the results to be expected for the full year. The Company has evaluated all subsequent events through the date the financial statements were issued.
Accounting Standards Adopted and Pending Adoption	Accounting Standards Pending Adoption In June 2016, the FASB issued guidance to change the accounting for credit losses. The guidance requires an entity to utilize a new impairment model known as the current expected credit loss ("CECL") model to estimate its lifetime "expected credit losses" and record an allowance that, when deducted from the amortized cost basis of the financial assets, presents the net amount expected to be collected on the financial assets. In May 2019, the FASB issued additional guidance to provide entities with an option to irrevocably elect the fair value option, applied on an instrument-by-instrument basis for eligible instruments, upon the adoption of the CECL model. The Company does not expect to elect this option. The CECL framework is expected to result in earlier recognition of credit losses and is expected to be significantly influenced by the composition, characteristics and quality of the Company's loan portfolio, as well as the prevailing economic conditions and forecasts. Except as discussed below, the Company would have applied the new guidance through a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption, which, for the Company, is January 1, 2020, with future adjustments to credit loss expectations recorded through the income statement as charges or credits to earnings. In the first quarter of 2020, in response to the COVID-19 pandemic, the CARES Act was enacted by the United States Congress and signed by the President. This CARES Act included an election to defer the implementation of CECL until the earlier of the cessation of the national emergency, or December 31, 2020. The Company is prepared for CECL implementation but elected to defer its effective date, as permitted by the CARES Act, because of the challenges associated with developing a reliable forecast of losses that may result from the unprecedented COVID-19 pandemic. Upon the adoption of CECL, the Company expects its allowance for credit losses related to all financial assets will increase to approximately $40-$44 million as of January 1, 2020 compared to its allowance for loan losses at December 31, 2019 of approximately $21 million. As noted above, this initial impact will be reflected as a cumulative-effect adjustment to retained earnings. In August 2018, the FASB amended the Compensation - Retirement Benefits – Defined Benefit Plans Topic of the Accounting Standards Codification to improve disclosure requirements for employers that sponsor defined benefit pension and other postretirement plans. The guidance removes disclosures that are no longer considered cost-beneficial, clarifies the specific requirements of disclosures, and adds disclosure requirements identified as relevant. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. In March 2020, the FASB issued guidance to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The amendments are effective as of March 12, 2020 through December 31, 2022. The Company does not expect these amendments to have a material effect on its financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on the Company’s financial position, results of operations or cash flows.
Reclassifications	Reclassifications Certain amounts reported in the periods ended March 31, 2019 and December 31, 2019 may have been reclassified to conform to the presentation for March 31, 2020. These reclassifications had no effect on net income or shareholders’ equity for the periods presented, nor did they materially impact trends in financial information.
