Securities in a Continuous Unrealized Loss Position

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.

The following tables summarize temporarily impaired securities, segregated by length of time the securities have been in a continuous unrealized loss position:

(Dollars in thousands)	Less than 12 Months					12 Months or Longer						Total

Further deterioration in credit quality of the underlying issuers of the securities, further deterioration in the condition of the financial services industry, a continuation or worsening of the current economic downturn, or additional declines in real estate values, among other things, may further affect the fair value of these securities and increase the potential that certain unrealized losses be designated as other-than-temporary in future periods, and the Corporation may incur additional write-downs.

Pooled Trust Preferred Securities Unrealized Losses Details

Trust Preferred Debt Securities of Individual Name Issuers

Included in debt securities in an unrealized loss position at March 31, 2013 and December 31, 2012 were 11 trust preferred security holdings issued by seven individual companies in the financial services industry, specifically, the banking sector.  Management believes the decline in fair value of these trust preferred securities primarily reflects investor concerns about global economic growth and how it will affect the recent and potential future losses in the financial services industry.  These concerns resulted in increased risk premiums for securities in this sector. Based on the information available through the filing date of this report, all individual name trust preferred debt securities held in our portfolio continue to accrue and make payments as expected with no payment deferrals or defaults on the part of the issuers.  As of March 31, 2013, trust preferred debt securities with an amortized cost of $11.9 million and unrealized losses of $2.2 million were rated below investment grade by Standard & Poors, Inc. (“S&P”).  Management reviewed the collectibility of these securities taking into consideration such factors as the financial condition of the issuers, reported regulatory capital ratios of the issuers, credit ratings including ratings in effect as of the reporting period date as well as credit rating changes between the reporting period date and the filing date of this report and other information.  We noted no additional downgrades to below investment grade between the reporting period date and the filing date of this report.  Based on these analyses, management concluded that it expects to recover the entire amortized cost basis of these securities. Furthermore, Washington Trust does not intend to sell these securities and its is not more likely than not that Washington Trust will be required to sell these securities before recovery of their cost basis, which may be at maturity. Therefore, management does not consider these investments to be other-than-temporarily impaired at March 31, 2013.

Trust Preferred Debt Securities in the Form of Collateralized Debt Obligations (“CDO”)

Washington Trust has pooled trust preferred holdings in the form of collateralized debt obligations. These pooled trust preferred holdings consist of trust preferred obligations of banking industry companies and, to a lesser extent, insurance industry companies.

(Dollars in thousands)	March 31, 2013							December 31, 2012
	Amortized Cost (1)		Fair Value		Unrealized Losses			Amortized Cost (1)		Fair Value		Unrealized Losses

Totals		$1,264		$404		($860	)		$4,036		$843		($3,193	)

(1) Net of other-than-temporary impairment losses recognized in earnings.

(2) In the first quarter of 2013, Washington Trust recognized an other-than-temporary impairment charge of $2.8 million on the Tropic CDO 1, tranche A4L (“Tropic”). On March 22, 2013, the trustee for the Tropic security issued a notice that a liquidation of the CDO entity, Tropic CDO I, Ltd., will take place at the direction of holders of the CDO tranches that are senior to certain subordinate tranches, of which Washington Trust is a note holder.  The estimated proceeds from the liquidation event are expected to be insufficient to satisfy the amount owed to the note holders of the CDO's subordinate tranches.  The Corporation had recognized other-than-temporary losses amounting to $2.1 million on this security in years prior to 2013; however, prior to the March 2013 announcement of the liquidation event, the expected future cash flows through the maturity of the CDO in the year 2033 were considered to be sufficient to recover the Corporation's remaining $2.8 million amortized cost.  The first quarter impairment loss reduces the Corporation's carrying value in the holding to zero.  The security had been classified in nonaccruing status with no interest recognition since 2009.

(3) Washington Trust’s investment is subordinate to two senior tranche levels. Valuations of the pooled trust preferred holdings is dependent in part on cash flows from underlying issuers.  Unexpected cash flow disruptions could have an adverse impact on the fair value and performance of this pooled trust preferred security.  Management believes the unrealized losses on this pooled trust preferred security primarily reflects investor concerns about global economic growth and how it will affect the recent and potential future losses in the financial services industry and the possibility of further incremental deferrals of or defaults on interest payments on trust preferred debentures by financial institutions participating in these pools.  These concerns have resulted in a substantial decrease in market liquidity and increased risk premiums for securities in this sector.  Credit spreads for issuers in this sector have remained wide during recent months, causing prices for this security holding to remain at low levels.

This security was placed on nonaccrual status in December 2008. The tranche instrument held by Washington Trust has been deferring interest payments since December 2008. The March 31, 2013 amortized cost was net of $1.2 million of credit-related impairment losses previously recognized in earnings reflective of payment deferrals and credit deterioration of the underlying collateral.  As of March 31, 2013, this security had unrealized losses of $860 thousand and a below investment grade rating of “C” by Moody’s.  Through the filing date of this report, there have been no additional rating changes on this security.  This credit rating status has been considered by management in its assessment of the impairment status of this security. Based on information available through the filing date of this report, there have been no additional adverse changes in deferral or default status of the underlying issuer institutions. Based on cash flow forecasts for this security, management expects to recover the remaining amortized cost of this security. Furthermore, Washington Trust does not intend to sell this security and its is not more likely than not that Washington Trust will be required to sell this security before recovery of its cost basis, which may be at maturity. Therefore, management does not consider the unrealized losses on this security to be other-than-temporary at March 31, 2013.

Rollforward of OTTI Recognized in Earnings

The following table presents a roll forward of the balance of cumulative credit-related impairment losses recognized on debt securities for the periods indicated:

(Dollars in thousands)
Three months ended March 31,	2013		2012
Balance at beginning of period		$3,325		$3,104
Credit-related impairment loss on debt securities for which an other-than-temporary impairment was not previously recognized	—		—
Additional increases to the amount of credit-related impairment loss on debt securities for which an other-than-temporary impairment was previously recognized	2,772		209
Balance at end of period		$6,097		$3,313

The anticipated cash flows expected to be collected from pooled trust preferred debt securities were discounted at the rate equal to the yield used to accrete the current and prospective beneficial interest for each security.  Significant inputs included estimated cash flows and prospective defaults and recoveries.  Estimated cash flows were generated based on the underlying seniority status and subordination structure of the pooled trust preferred debt tranche at the time of measurement.  Prospective default and recovery estimates affecting projected cash flows were based on analysis of the underlying financial condition of individual issuers, and took into account capital adequacy, credit quality, lending concentrations, and other factors.

All cash flow estimates were based on the underlying security’s tranche structure and contractual rate and maturity terms.  The present value of the expected cash flows was compared to the current outstanding balance of the tranche to determine the ratio of the estimated present value of expected cash flows to the total current balance for the tranche.  This ratio was then multiplied by the principal balance of Washington Trust’s holding to determine the credit-related impairment loss.  The estimates used in the determination of the present value of the expected cash flows are susceptible to changes in future periods, which could result in additional credit-related impairment losses.
