Washington Trust Bancorp, Inc. (the “Bancorp”) is a publicly-owned registered bank holding company and financial holding company.  The Bancorp owns all of the outstanding common stock of The Washington Trust Company, of Westerly (the “Bank”), a Rhode Island chartered commercial bank founded in 1800.  Through its subsidiaries, the Bancorp offers a complete product line of financial services including commercial, residential and consumer lending, retail and commercial deposit products, and wealth management services through its offices in Rhode Island, eastern Massachusetts and Connecticut.

The consolidated financial statements include the accounts of the Bancorp and its subsidiaries (collectively, the “Corporation” or “Washington Trust”).  All significant intercompany transactions have been eliminated.

The accounting and reporting policies of the Corporation conform to accounting principles generally accepted in the United States of America (“GAAP”) and to general practices of the banking industry.  In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period.  Actual results could differ from those estimates.  Material estimates that are particularly susceptible to change are the determination of the allowance for loan losses, the review of goodwill for impairment and the assessment of investment securities for impairment.

The unaudited consolidated financial statements of the Corporation presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by GAAP. In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures considered necessary for the fair presentation of the accompanying consolidated financial statements have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2014 .

Receivables - Troubled Debt Restructurings by Creditors - Topic 310

Accounting Standards Update No. 2014-04, “Reclassifications of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure” (“ASU 2014-04”), was issued in January 2014 and clarifies when banks and similar institutions (creditors) should reclassify mortgage loans collateralized by residential real estate properties from the loan portfolio to other real estate owned (“OREO”). ASU 2014-04 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The Corporation elected the prospective transition method and the adoption of ASU 2014-04 did not have a material impact on the Corporation’s consolidated financial statements.

Revenue from Contracts with Customers - Topic 606

Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), was issued in May 2014 and provides a revenue recognition framework for any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts are within the scope of other accounting standards. ASU 2014-09 is 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. The Corporation is currently evaluating the impact that ASU 2014-09 will have on the its consolidated financial statements and related disclosures. The Corporation has not yet selected a transition method nor has it determined the effect of ASU 2014-09 on its ongoing financial reporting.

The Bank maintains certain average reserve balances to meet the requirements of the Board of Governors of the Federal Reserve System (“FRB”).  Some or all of these reserve requirements may be satisfied with vault cash. Reserve balances amounted to $10.1 million at March 31, 2015 and $8.0 million at December 31, 2014 and were included in cash and due from banks in the Consolidated Balance Sheets.

As of March 31, 2015 and December 31, 2014 , cash and due from banks included interest-bearing deposits in other banks of $47.0 million and $42.7 million , respectively.

At March 31, 2015 and December 31, 2014 , securities available for sale and held to maturity with a fair value of $347.6 million and $350.5 million , respectively, were pledged as collateral for Federal Home Loan Bank of Boston (“FHLBB”) borrowings and letters of credit, potential borrowings with the FRB, certain public deposits and for other purposes. See Note 8 for additional discussion of FHLBB borrowings.

Included in the above table are debt securities with an amortized cost balance of $98.1 million and a fair value of $95.0 million at March 31, 2015 that are callable at the discretion of the issuers.  Final maturities of the callable securities range from 6 months to 22 years, with call features ranging from 1 month to 2 years.

Other-Than-Temporary Impairment Assessment

The Corporation assesses whether the decline in fair value of investment securities is other-than-temporary on a regular basis. Unrealized losses on debt securities may occur from current market conditions, increases in interest rates since the time of purchase, a structural change in an investment, volatility of earnings of a specific issuer, or deterioration in credit quality of the issuer.  Management evaluates impairments in value both qualitatively and quantitatively to assess whether they are other‑than‑temporary.
