New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	3. Recent Accounting Pronouncements *Accounting Standards* Adopted in 2019 In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842),” which requires lessees to recognize leases on their balance sheets and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, “Land Easement Practical Expedient for Transition to Topic 842”; ASU No. 2018-10, “Codification Improvements to Topic 842, Leases”; and ASU No. 2018-11, “Targeted Improvements.” The new standard establishes a right-of-use model (“ROU”) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Company has adopted this guidance using the modified-retrospective transition method, which allows the adoption of the accounting standard prospectively without adjusting comparative prior period financial information using the effective date as our date of initial application. Consequently, the Company will not update financial information nor provide the disclosures required under the new standard for dates and periods before January 1, 2019. The new standard provides a number of optional practical expedients in transition. We have elected the ‘package of practical expedients’, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We also elected all of the new standard’s available transition practical expedients. Upon adoption, we recognized an operating lease liability of $41.2 million, and a corresponding ROU asset of $40.6 million based on the present value of the remaining minimum lease payments under current leasing standards for existing operating leases. We elected the short-term lease recognition exemption for all leases that qualify. Consequently, we will not recognize ROU assets or lease liabilities, for those leases that qualify, including existing short-term leases of those assets in transition. We also elected the practical expedient to not separate lease and non-lease components for all of our leases. See Note 10. In March 2017, the FASB issued ASU 2017-08, “Receivables- Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” This update amends the amortization period for certain purchased callable debt securities held at a premium. The amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. This update affects all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company does not expect the adoption of this guidance to have an impact on the Company’s Consolidated Financial Statements since the accounting on the Company’s purchased callable debt securities have been consistent with the requirements of ASU 2017-8. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815),” which targeted improvements to accounting for hedging activities. The amendments in this update are intended 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. To meet that objective, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. ASU 2017-12, which became effective for us on January 1, 2019, did not have a material impact on our financial statements. In October 2018, the FASB issued ASU 2018-16, “Derivatives and Hedging (Topic 815) - Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes.” The amendments in this update permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the interest rates on direct U.S. Treasury obligations, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate and the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate. ASU 2018-16, which became effective for us on January 1, 2019, did not have a material impact on our financial statements. In March 2019, the FASB amended ASU 2016-02, “Leases (Topic 842),” to align the guidance for fair value of the underlying asset by lessors that are not manufacturers or dealers in Topic 842 with that of existing guidance. As a result, the fair value of the underlying asset at lease commencement is its cost, reflecting any volume or trade discounts that may apply. However, if there has been a significant lapse of time between when the underlying asset is acquired and when the lease commences, the definition of fair value (in Topic 820, Fair Value Measurement) should be applied. (Issue 1). The ASU also requires lessors within the scope of Topic 942, Financial Services—Depository and Lending, to present all “principal payments received under leases” within investing activities. (Issue 2). Finally, the ASU exempts both lessees and lessors from having to provide certain interim disclosures in the fiscal year in which a company adopts the new leases standard. (Issue 3). The transition and effective date provisions apply to Issue 1 and Issue 2. They do not apply to Issue 3 because the amendments for that Issue are to the original transition requirements in Topic 842. The effective date of those amendments is for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company has adopted the amendments of this guidance as part of the adoption of Topic 842 on January 1, 2019, using the transition methodology set forth in paragraph 842-10-65-1(c). *Other Accounting Standards* In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This update requires an entity to use a broader range of reasonable and supportable (“R&S”) forecasts, in addition to historical experience and current conditions, to develop an expected credit loss estimate, referred to as the Current Expected Credit Loss (“CECL”) model, for financial assets and net investments that are not accounted for at fair value through net income. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses to the amount by which fair value is below amortized cost. ASU 2016-13 becomes effective for interim and annual periods beginning after December 15, 2019. The Company has established a multidisciplinary project team and implementation plan, reached accounting decisions on various matters, developed a conceptual framework, and engaged an outside firm to develop econometric regression models for net losses during the R&S forecast period. The Company continues to test and refine the CECL models and has completed one preliminary calculation with two more scheduled before adoption. The Company continues to perform testing and sensitivity analysis on its modeling assumptions and results. Our planned approach for estimating expected life-time credit losses is expected to include, among other things, the following key components for all loan portfolio segments: a. The use of a probability of default/loss given default methodology; b. A number of scenarios based on forecasts from an outside economic forecasting company to develop economic forecasts for the R&S period; c. An initial R&S forecast period of six quarters for all loan portfolio segments, which reflects management's expectation of losses based on forward-looking economic scenarios over that time; d. A post-R&S reversion period of six quarters using a linear transition to the historical loss rates for each loan pool; e. A historical loss period that includes the last recession; and f. Prepayments rates based on our historical experience. The ultimate impact is expected to be influenced by, among other things, the macroeconomic conditions and forecasts at adoption; and other management judgments. We plan to adopt this new standard on January 1, 2020. We are not yet able to disclose the quantitative effect on our consolidated financial position and results of operations as we are continuing to evaluate the impact of the adoption of this ASU. In January 2017, the FASB issued ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” This update simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Adoption of this update is on a prospective basis and the amendments in this update are to be applied to annual periods beginning after December 15, 2019. Adoption of ASU 2017-04 is not expected to have a material impact on the Company’s Consolidated Financial Statements. In July 2017, the FASB issued ASU 2017-11, “Earnings per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480) and Derivatives and Hedging (Topic 815).” There are two parts to this update. Part I of this update addresses the complexity of accounting for certain financial instruments with down round features. Down round features are features of certain equity-linked instruments that result in the strike price being reduced on the basis of the pricing of future equity offerings. Part II of this update addresses the difficulty in navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB Accounting Standards Codification. This pending content is the result of the indefinite deferral of accounting requirements about mandatorily redeemable financial instruments of certain nonpublic entities and certain mandatorily redeemable noncontrolling interests. The amendments in this update are effective for fiscal years beginning after December 15, 2020. Early adoption is permitted for all entities, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The amendments in part I of this update should be applied in either of the following ways: (i) Retrospectively to outstanding financial instruments with a down round feature by means of a cumulative-effect adjustment to the statement of financial position as of the beginning of the first fiscal year and interim periods in which the pending content that links to this paragraph is effective; or (ii) Retrospectively to outstanding financial instruments with a down round feature for each prior reporting period presented in accordance with the guidance on accounting changes in paragraphs 250-10-45-5 through 45-10. The amendments to Part II of this update do not require any transition guidance because those amendments do not have an accounting effect. The Company is currently evaluating the impact on its Consolidated Financial Statements. In August 2018, the FASB issued ASU No. 2018-13, “Disclosure Framework Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU eliminates, adds 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. ASU No. 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. As ASU No. 2018-13 only revises disclosure requirements, we do not expect it to have a material impact on the Company’s Consolidated Financial Statements. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, which clarifies and improves areas of guidance related to the recently issued standards on credit losses (ASU 2016-13), hedging (ASU 2017-12), and recognition 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 the Company’s 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 May 2019, the FASB issued ASU No. 2019-05, “Financial Instruments Credit Losses (Topic 326); Targeted Transition Relief.” This ASU allows entities to irrevocably elect, upon adoption of ASU 2016-13, the fair value option on financial instruments that (1) were previously recorded at amortized cost and (2) are within the scope of ASC 326-20 if the instruments are eligible for the fair value option under ASC 825-10. The fair value option election does not apply to held-to-maturity debt securities. Entities are required to make this election on an instrument by instrument basis. ASU 2019-05 has the same effective date as ASU 2016-13 (i.e., the first quarter of 2020). The Company does not have financial instruments that were previously recorded at amortized cost, and therefore, ASU 2019-05 is not expected to impact the Company’s Consolidated Financial Statements.

3. Recent Accounting Pronouncements

Accounting Standards Adopted in 2019

In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases (Topic 842),” which requires lessees to recognize leases on their balance sheets and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, “Land Easement Practical Expedient for Transition to Topic 842”; ASU No. 2018-10, “Codification Improvements to Topic 842, Leases”; and ASU No. 2018-11, “Targeted Improvements.” The new standard establishes a right-of-use model (“ROU”) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement.

The Company has adopted this guidance using the modified-retrospective transition method, which allows the adoption of the accounting standard prospectively without adjusting comparative prior period financial information using the effective date as our date of initial application. Consequently, the Company will not update financial information nor provide the disclosures required under the new standard for dates and periods before January 1, 2019.

The new standard provides a number of optional practical expedients in transition. We have elected the ‘package of practical expedients’, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We also elected all of the new standard’s available transition practical expedients.

Upon adoption, we recognized an operating lease liability of $41.2 million, and a corresponding ROU asset of $40.6 million based on the present value of the remaining minimum lease payments under current leasing standards for existing operating leases.

We elected the short-term lease recognition exemption for all leases that qualify. Consequently, we will not recognize ROU assets or lease liabilities, for those leases that qualify, including existing short-term leases of those assets in transition. We also elected the practical expedient to not separate lease and non-lease components for all of our leases. See Note 10.

In March 2017, the FASB issued ASU 2017-08, “Receivables- Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” This update amends the amortization period for certain purchased callable debt securities held at a premium. The amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. This update affects all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company does not expect the adoption of this guidance to have an impact on the Company’s Consolidated Financial Statements since the accounting on the Company’s purchased callable debt securities have been consistent with the requirements of ASU 2017-8.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815),” which targeted improvements to accounting for hedging activities. The amendments in this update are intended 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. To meet that objective, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. ASU 2017-12, which became effective for us on January 1, 2019, did not have a material impact on our financial statements.

In October 2018, the FASB issued ASU 2018-16, “Derivatives and Hedging (Topic 815) - Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes.” The amendments in this update permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the interest rates on direct U.S. Treasury obligations, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate and the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate. ASU 2018-16, which became effective for us on January 1, 2019, did not have a material impact on our financial statements.

In March 2019, the FASB amended ASU 2016-02, “Leases (Topic 842),” to align the guidance for fair value of the underlying asset by lessors that are not manufacturers or dealers in Topic 842 with that of existing guidance. As a result, the fair value of the underlying asset at lease commencement is its cost, reflecting any volume or trade discounts that may apply. However, if there has been a significant lapse of time between when the underlying asset is acquired and when the lease commences, the definition of fair value (in Topic 820, Fair Value Measurement) should be applied. (Issue 1). The ASU also requires lessors within the scope of Topic 942, Financial Services—Depository and Lending, to present all “principal payments received under leases” within investing activities. (Issue 2). Finally, the ASU exempts both lessees and lessors from having to provide certain interim disclosures in the fiscal year in which a company adopts the new leases standard. (Issue 3). The transition and effective date provisions apply to Issue 1 and Issue 2. They do not apply to Issue 3 because the amendments for that Issue are to the original transition requirements in Topic 842. The effective date of those amendments is for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company has adopted the amendments of this guidance as part of the adoption of Topic 842 on January 1, 2019, using the transition methodology set forth in paragraph 842-10-65-1(c).

Other Accounting Standards

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This update requires an entity to use a broader range of reasonable and supportable (“R&S”) forecasts, in addition to historical experience and current conditions, to develop an expected credit loss estimate, referred to as the Current Expected Credit Loss (“CECL”) model, for financial assets and net investments that are not accounted for at fair value through net income. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses to the amount by which fair value is below amortized cost. ASU 2016-13 becomes effective for interim and annual periods beginning after December 15, 2019.

The Company has established a multidisciplinary project team and implementation plan, reached accounting decisions on various matters, developed a conceptual framework, and engaged an outside firm to develop econometric regression models for net losses during the R&S forecast period. The Company continues to test and refine the CECL models and has completed one preliminary calculation with two more scheduled before adoption. The Company continues to perform testing and sensitivity analysis on its modeling assumptions and results. Our planned approach for estimating expected life-time credit losses is expected to include, among other things, the following key components for all loan portfolio segments: a. The use of a probability of default/loss given default methodology; b. A number of scenarios based on forecasts from an outside economic forecasting company to develop economic forecasts for the R&S period; c. An initial R&S forecast period of six quarters for all loan portfolio segments, which reflects management's expectation of losses based on forward-looking economic scenarios over that time; d. A post-R&S reversion period of six quarters using a linear transition to the historical loss rates for each loan pool; e. A historical loss period that includes the last recession; and f. Prepayments rates based on our historical experience. The ultimate impact is expected to be influenced by, among other things, the macroeconomic conditions and forecasts at adoption; and other management judgments. We plan to adopt this new standard on January 1, 2020. We are not yet able to disclose the quantitative effect on our consolidated financial position and results of operations as we are continuing to evaluate the impact of the adoption of this ASU.

In January 2017, the FASB issued ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” This update simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Adoption of this update is on a prospective basis and the amendments in this update are to be applied to annual periods beginning after December 15, 2019. Adoption of ASU 2017-04 is not expected to have a material impact on the Company’s Consolidated Financial Statements.

In July 2017, the FASB issued ASU 2017-11, “Earnings per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480) and Derivatives and Hedging (Topic 815).” There are two parts to this update. Part I of this update addresses the complexity of accounting for certain financial instruments with down round features. Down round features are features of certain equity-linked instruments that result in the strike price being reduced on the basis of the pricing of future equity offerings. Part II of this update addresses the difficulty in navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB Accounting Standards Codification. This pending content is the result of the indefinite deferral of accounting requirements about mandatorily redeemable financial instruments of certain nonpublic entities and certain mandatorily redeemable noncontrolling interests. The amendments in this update are effective for fiscal years beginning after December 15, 2020. Early adoption is permitted for all entities, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The amendments in part I of this update should be applied in either of the following ways: (i) Retrospectively to outstanding financial instruments with a down round feature by means of a cumulative-effect adjustment to the statement of financial position as of the beginning of the first fiscal year and interim periods in which the pending content that links to this paragraph is effective; or (ii) Retrospectively to outstanding financial instruments with a down round feature for each prior reporting period presented in accordance with the guidance on accounting changes in paragraphs 250-10-45-5 through 45-10. The amendments to Part II of this update do not require any transition guidance because those amendments do not have an accounting effect. The Company is currently evaluating the impact on its Consolidated Financial Statements.

In August 2018, the FASB issued ASU No. 2018-13, “Disclosure Framework Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU eliminates, adds 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. ASU No. 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. As ASU No. 2018-13 only revises disclosure requirements, we do not expect it to have a material impact on the Company’s Consolidated Financial Statements.

In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, which clarifies and improves areas of guidance related to the recently issued standards on credit losses (ASU 2016-13), hedging (ASU 2017-12), and recognition 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 the Company’s 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 May 2019, the FASB issued ASU No. 2019-05, “Financial Instruments Credit Losses (Topic 326); Targeted Transition Relief.” This ASU allows entities to irrevocably elect, upon adoption of ASU 2016-13, the fair value option on financial instruments that (1) were previously recorded at amortized cost and (2) are within the scope of ASC 326-20 if the instruments are eligible for the fair value option under ASC 825-10. The fair value option election does not apply to held-to-maturity debt securities. Entities are required to make this election on an instrument by instrument basis. ASU 2019-05 has the same effective date as ASU 2016-13 (i.e., the first quarter of 2020). The Company does not have financial instruments that were previously recorded at amortized cost, and therefore, ASU 2019-05 is not expected to impact the Company’s Consolidated Financial Statements.
