As issued, ASU 2014-09 was effective for annual periods beginning after December 15, 2016, including interim periods within that reporting period with early adoption not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. In August 2015, Accounting Standards Update No. 2015-14, “Deferral of the Effective Date” (“ASU 2015-14”) was issued and delayed the effective date of ASU 2014-09 to annual and interim periods in fiscal years beginning after December 15, 2017. In 2016, Accounting Standards Update No. 2016-08, “Principal versus Agent Considerations” (“ASU 2016-08”), Accounting Standards Update No. 2016-10, “Identifying Performance Obligations and Licensing” (“ASU 2016-10”) and Accounting Standards Update No. 2016-12, “Narrow-Scope Improvements and Practical Expedients” (“ASU 2016-12”) were issued. These ASUs did not change the core principle for revenue recognition in Topic 606; instead, the amendments provided more detailed guidance in a few areas and additional implementation guidance and examples to reduce the degree of judgment necessary to comply with Topic 606. The effective date and transition requirements for ASU 2016-08, ASU 2016-10 and ASU 2016-12 were the same as those provided by ASU 2015-14.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Management assembled a project team to address the changes pursuant to Topic 606. The project team completed a scope assessment and contract review for in-scope revenue streams. The Corporation's largest source of revenue is net interest income on financial assets and liabilities, which was explicitly excluded from the scope of this ASU. Revenue streams that were within the scope of Topic 606 include wealth management revenues, service charges on deposit accounts and card interchange fees.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Corporation adopted Topic 606 “Revenue from Contracts with Customers” effective January 1, 2018 and has applied the guidance to all contracts within the scope of Topic 606 as of that date. As a result, the Corporation has modified its accounting policy for revenue recognition as disclosed in </font><font style="font-family:inherit;font-size:10pt;">Note 1</font><font style="font-family:inherit;font-size:10pt;">. The Corporation adopted the provisions of Topic 606 using the modified retrospective method, therefore, the prior period comparative information has not been adjusted and continues to be reported under Topic 605. Additionally, Topic 606 provided certain practical expedients. The Corporation applied the practical expedient pertaining to contracts with original expected duration of one year or less and therefore, does not disclose information about remaining performance obligations on such contracts. The Corporation also applied the practical expedient pertaining to contracts for which, at contract inception, the period between when the entity transfers the services and when the customer pays for those services was one year or less, and therefore, does not adjust the consideration from customers for the effects of a significant financing component. As the result of the adoption of Topic 606 on January 1, 2018, there was no cumulative effect adjustment required and there was no material impact on the Corporation’s consolidated financial statements.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Financial Instruments - Overall - Topic 825</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Accounting Standards Update No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”), was issued in January 2016 and provides revised guidance related to the accounting for and reporting of financial instruments. Some of the main provisions include: requiring most equity securities to be reported at fair value with unrealized gains and losses reported in the income statement; requiring separate presentation of financial assets and liabilities by measurement category and form (i.e. securities or loans); clarifying that entities must assess valuation allowances on a deferred tax asset related to available for sale debt securities in combination with their other deferred tax assets; and eliminating the requirement to disclose the method and significant assumptions used to estimate fair value for financial instruments measured at amortized cost on the balance sheet. Certain provisions under ASU 2016-01 require prospective application, while other provisions require a modified retrospective application to all periods presented in the consolidated financial statements upon adoption. ASU 2016-01 was effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Management adopted the provisions of ASU 2016-01 effective January 1, 2018. The adoption did not have a material impact on the Corporation’s consolidated financial statements.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Accounting Standards Update No. 2018-03, “Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2018-03”), was issued in February 2018 to clarify certain aspects of the guidance issued in ASU 2016-01. Companies, such as Washington Trust, were not required to adopt the provisions of ASU 2018-03 until the interim period beginning after June 15, 2018. However, early adoption was permitted, as long as ASU 2016-01 provisions were adopted. Management early adopted the provisions of ASU 2018-03 effective January 1, 2018. The adoption did not have an impact on the Corporation’s consolidated financial statements.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Statement of Cash Flows - Topic 230</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Accounting Standards Update No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”), was issued in August 2016. ASU 2016-15 provides classification guidance on certain cash receipts and cash payments, including, but not limited to, debt prepayment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of bank-owned life insurance policies and distributions received from equity method investees. The adoption of ASU 2016-15 requires a retrospective transition method applied to each period presented. This ASU was effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Management adopted the provisions of ASU 2016-15 effective January 1, 2018.

ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash. Restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The adoption of ASU 2016-18 requires a retrospective transition method applied to each period presented. This ASU was effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Management adopted the provisions of ASU 2016-18 effective January 1, 2018.

ASU 2017-07 requires that employers include the service cost component of net periodic benefit cost in the same line item as other employee compensation costs and all other components of net periodic benefit cost in a separate line item(s) in the statement of income. In addition, the line item in which the components of net periodic benefit cost other than the service cost are included shall be identified as such on the statement of income or in the notes to the financial statements. ASU 2017-07 was effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017 requiring retrospective application for all periods presented. Management adopted the provisions of ASU 2017-07 effective January 1, 2018, utilizing the practical expedient that permitted employers to use the amounts previously disclosed in notes to financial statements as an estimation basis for applying the retrospective application requirements. The adoption of ASU 2017-07 resulted in an increase in salaries and employee benefits, a decrease</font><font style="font-family:inherit;font-size:10pt;font-weight:bold;"> </font><font style="font-family:inherit;font-size:10pt;">in other expenses and no change to net income.

ASU 2017-09 was effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017, with provisions applied on a prospective basis.  Management adopted the provisions of ASU 2017-09 effective January 1, 2018.

ASU 2016-02 requires lessees to recognize most leases on the balance sheet. The recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee will depend on its classification as a finance or operating lease. ASU 2016-02 requires a modified retrospective transition, with a number of practical expedients that entities may elect to apply. In January 2018, Accounting Standards Update No. 2018-01, “Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842” was issued to address concerns about the costs and complexity of complying with the transition provisions of ASU 2016-02. In July 2018, Accounting Standards Update No. 2018-10, “Codification Improvements to Topic 842, Leases” was issued to provide more detailed guidance and additional clarification for implementing ASU 2016-02. Also in July 2018, Accounting Standards Update No. 2018-11, “Targeted Improvements” was issued and allows for an optional transition method in which the provisions of Topic 842 would be applied upon the adoption date and would not have to be retroactively applied to the earliest reporting period presented in the consolidated financial statements. The Corporation intends to use this optional transition method for the adoption of Topic 842. In December 2018, Accounting Standards Update No. 2018-20, “Leases (Topic 842) Narrow-Scope Improvement for Lessors” was issued to address lessors’ concerns about sales taxes and other similar taxes collected from lessees, certain lessor costs, and recognition of variable payments for contracts with lease and non-lease components. These ASUs are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Management assembled a project team to address the changes pursuant to Topic 842. The project team identified and reviewed all lease agreements in scope of Topic 842. The Corporation rents premises used in business operations under non-cancelable operating leases, which as of December 31, 2018 are not reflected in its Consolidated Balance Sheets. Upon adoption of ASU 2016-02 on January 1, 2019, the Corporation expects to recognize </font><font style="font-family:inherit;font-size:10pt;">$28.9 million</font><font style="font-family:inherit;font-size:10pt;"> in operating lease right-of-use-assets, </font><font style="font-family:inherit;font-size:10pt;">$30.9 million</font><font style="font-family:inherit;font-size:10pt;"> in operating lease liabilities, a reduction in rent-related liabilities of </font><font style="font-family:inherit;font-size:10pt;">$2.9 million</font><font style="font-family:inherit;font-size:10pt;">, a reduction of net deferred tax assets of </font><font style="font-family:inherit;font-size:10pt;">$222 thousand</font><font style="font-family:inherit;font-size:10pt;"> and a cumulative effect adjustment (net of taxes) that will increase beginning retained earnings by approximately </font><font style="font-family:inherit;font-size:10pt;">$722 thousand</font><font style="font-family:inherit;font-size:10pt;"> in the Consolidated Balance Sheet. The Corporation does not expect a material change to the timing in recognition of expense associated with our leases in the Consolidated Statements of Income.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Financial Instruments - Credit Losses - Topic 326</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Accounting Standards Update No. 2016-13, “Financial Instruments - Credit Losses” (“ASU 2016-13”), was issued in June 2016. ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 provides for a modified retrospective transition, resulting in a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is effective, except for debt securities for which an other-than-temporary impairment has previously been recognized. For these debt securities, a prospective transition approach will be adopted in order to maintain the same amortized cost prior to and subsequent to the effective date of ASU 2016-13. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2019, with early adoption permitted in 2019. The Corporation will adopt ASU 2016-03 on January 1, 2020 and is currently evaluating the effect that this ASU will have on the consolidated financial statements and disclosures.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Management has assembled a project team that meets regularly to evaluate the provisions of this ASU, to address the additional data requirements necessary, to determine the approach for implementation and to identify new internal controls over enhanced processes that will be put into place for estimating the allowance under ASU 2016-13. This has included assessing the adequacy of existing loan and loss data, as well as developing models for default and loss estimates. The Corporation expects to continue the validation of models and the development of accounting policies and internal controls throughout 2019. Additionally, the Corporation expects to execute “trial” or “parallel” runs of its ASU 2016-13 compliant methodology in 2019.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Derivatives and Hedging - Topic 815</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Accounting Standards Update No. 2017-12, “Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”), was issued in August 2017 to better align financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, with early adoption, including adoption in an interim period, permitted. Upon adoption, the provisions of ASU 2017-12 will be applied using a modified retrospective transition method with the cumulative effect of the change in the opening balance of retained earnings. In addition, ASU 2017-12 also permits the reclassification of eligible securities from the held-to-maturity classification to the available-for-sale classification. The Corporation will adopt the provisions of ASU 2017-12 on January 1, 2019. As permitted by ASU 2017-12, debt securities classified as held-to-maturity with an amortized cost of </font><font style="font-family:inherit;font-size:10pt;">$10.4 million</font><font style="font-family:inherit;font-size:10pt;"> and a fair value of </font><font style="font-family:inherit;font-size:10pt;">$10.3 million</font><font style="font-family:inherit;font-size:10pt;"> will be reclassified to available-for-sale upon the adoption date. An unrealized loss of </font><font style="font-family:inherit;font-size:10pt;">$99 thousand</font><font style="font-family:inherit;font-size:10pt;"> associated with these debt securities will be recognized in the accumulated other comprehensive income component of shareholders’ equity at the date of adoption.

ASU 2018-16 is effective for fiscal years beginning after December 15, 2018, and interim periods with those fiscal years. The provisions require prospective application for qualifying new or re-designated hedging relationships entered into on or after the date of adoption. The adoption of ASU 2018-16 is not expected to have a material impact on the Corporation’s consolidated financial statements.</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Fair Value Measurement - Topic 820</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Accounting Standards Update No. 2018-13, “Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”), was issued in August 2018 to modify the disclosure requirements related to fair value. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted, including adoption in an interim period. Certain provisions under ASU 2018-13 require prospective application, while other provisions require retrospective application to all periods presented in the consolidated financial statements upon adoption.

Implementation costs would either be capitalized or expensed as incurred depending on the project stage. All costs in the preliminary and post-implementation project stages are expensed as incurred, while certain costs within the application development stage are capitalized. The provisions under ASU 2018-15 can either be applied retrospectively or prospectively. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted, including adoption in an interim period.
