New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS In April 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, that clarifies and improves areas of guidance related to the recently issued standards on credit losses (ASU 2016-13), hedging (ASU 2017-12), and recognition and measurement of financial instruments (ASU 2016-01). The amendments generally have the same effective dates as their related standards. If already adopted, the amendments of ASU 2016-01 and ASU 2016-13 are effective for fiscal years beginning after December 15, 2019 and the amendments of ASU 2017-12 are effective as of the beginning of the Company’s next annual reporting period; early adoption is permitted. The Company previously adopted both ASU 2017-12 and ASU 2016-01 and does not expect the amendments of ASU 2019-04 will have a material impact on its consolidated financial statements. The Company is continuing to evaluate the impact of ASU 2016-13 and will consider the amendments of ASU 2019-04 as part of that process. In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The amendments also require the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, including reasonably certain renewal periods. The amendments in the ASU are effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The Company is assessing the impact that this guidance will have on its consolidated financial statements. 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. This ASU adds, eliminates, and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The ASU is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. Entities are also allowed to elect early adoption of the eliminated or modified disclosure requirements and delay adoption of the added disclosure requirements until their effective date. As the ASU only revises disclosure requirements, this guidance will not have a material impact on the Company's consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses. The ASU, as amended, is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments that are not accounted for at fair value through net income, including loans held for investment, held-to-maturity debt securities, trade and other receivables, net investments in leases and other commitments to extend credit held by a reporting entity at each reporting date. The amendments require that financial assets measured at amortized cost be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The ASU eliminates the current framework of recognizing probable incurred losses and instead requires an entity to use its current estimate of all expected credit losses over the contractual life. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the financial assets. For purchased financial assets with a more-than-insignificant amount of credit deterioration since origination (“PCD assets”) that are measured at amortized cost, an allowance for expected credit losses is recorded as an adjustment to the cost basis of the asset. Subsequent changes in estimated cash flows would be recorded as an adjustment to the allowance and through the statement of income. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security's cost basis. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. For most debt securities, the transition approach requires a cumulative-effect adjustment to the statement of financial position as of the beginning of the first reporting period the guidance is effective. For other-than-temporarily impaired debt securities and PCD assets, the guidance will be applied prospectively. The Company is currently in the process of evaluating the impact of the amended guidance on its consolidated financial statements and the reserve for credit losses may increase upon adoption given that the allowance will be required to cover the full remaining expected life of the portfolio upon adoption, rather than the incurred loss model under current U.S. GAAP. The extent of this increase is still being evaluated and will depend on economic conditions and the composition of the Company’s loan, lease and held-to-maturity securities portfolios at the time of adoption. In February 2016, the FASB issued ASU 2016-02, Leases. The ASU, as amended, requires lessees to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, and a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. The guidance also simplifies the accounting for sale and leaseback transactions and introduces new disclosure requirements for leasing arrangements. Accounting by lessors is largely unchanged. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company has adopted the standard effective October 1, 2019 utilizing the transition method allowed under ASU 2018-11 and will not restate comparative periods. The Company leases a number of properties under non-cancelable operating leases which will be subject to this ASU. We have elected the package of practical expedients permitted under the transition guidance, which allows us to carryforward our historical lease classification and our assessment on whether a contract is or contains a lease. We have also elected to keep leases with an initial term of 12 months or less off the balance sheet. The adoption of the new standard has resulted in an increase in other assets and an increase in other liabilities on October 1, 2019 that is not material. The Company has recognized no cumulative effect adjustment to the beginning balance of retained earnings upon adoption and there will be no material impact to our Consolidated Statement of Income as a result of this ASU.
