The Trusts are reflected as junior subordinated debentures in the Condensed Consolidated Balance Sheets. The common stock issued by the Trusts is recorded in other assets in the Condensed Consolidated Balance Sheets, and totaled $6.9 million at March 31, 2012 and December 31, 2011.

On January 1, 2007, the Company selected the fair value measurement option for certain pre-existing junior subordinated debentures (the Umpqua Statutory Trusts). The remaining junior subordinated debentures as of the adoption date were acquired through business combinations and were measured at fair value at the time of acquisition. In 2007, the Company issued two series of trust preferred securities and elected to measure each instrument at fair value. Accounting for the junior subordinated debentures originally issued by the Company at fair value enables us to more closely align our financial performance with the economic value of those liabilities. Additionally, we believe it improves our ability to manage the market and interest rate risks associated with the junior subordinated debentures. The junior subordinated debentures measured at fair value and amortized cost are presented as separate line items on the balance sheet. The ending carrying (fair) value of the junior subordinated debentures measured at fair value represents the estimated amount that would be paid to transfer these liabilities in an orderly transaction amongst market participants under current market conditions as of the measurement date.

The significant inputs utilized in the estimation of fair value of these instruments are the credit risk adjusted spread and three month LIBOR. The credit risk adjusted spread represents the nonperformance risk of the liability, contemplating the inherent risk of the obligation. Generally, an increase in the credit risk adjusted spread and/or a decrease in the three month LIBOR will result in positive fair value adjustments. Conversely, a decrease in the credit risk adjusted spread and/or an increase in the three month LIBOR will result in negative fair value adjustments.

Through the first quarter of 2010 we obtained valuations from a third-party pricing service to assist with the estimation and determination of fair value of these liabilities. In these valuations, the credit risk adjusted interest spread for potential new issuances through the primary market and implied spreads of these instruments when traded as assets on the secondary market, were estimated to be significantly higher than the contractual spread of our junior subordinated debentures measured at fair value. The difference between these spreads has resulted in the cumulative gain in fair value, reducing the carrying value of these instruments as reported on our Consolidated Balance Sheets. In July 2010, the Dodd-Frank Act was signed into law which, among other things, limits the ability of certain bank holding companies to treat trust preferred security debt issuances as Tier 1 capital. This law may require many banks to raise new Tier 1 capital and is expected to effectively close the trust-preferred securities markets from offering new issuances in the future. As a result of this legislation, our third-party pricing service noted that they were no longer to able to provide reliable fair value estimates related to these liabilities given the absence of observable or comparable transactions in the market place in recent history or as anticipated into the future.

Due to inactivity in the junior subordinated debenture market and the inability to obtain observable quotes of our, or similar, junior subordinated debenture liabilities or the related trust preferred securities when traded as assets, we utilize an income approach valuation technique to determine the fair value of these liabilities using our estimation of market discount rate assumptions. The Company monitors activity in the trust preferred and related markets, to the extent available, changes related to the current and anticipated future interest rate environment, and considers our entity-specific creditworthiness, to validate the reasonableness of the credit risk adjusted spread and effective yield utilized in our discounted cash flow model. Regarding the activity in and condition of the junior subordinated debt market, we noted no observable changes in the current period as it relates to companies comparable to our size and condition, in either the primary or secondary markets. Relating to the interest rate environment, we considered the change in slope and shape of the forward LIBOR swap curve in the current period, the affects of which did not result in a significant change in the fair value of these liabilities.

The Company's specific credit risk is implicit in the credit risk adjusted spread used to determine the fair value of our junior subordinated debentures. As our Company is not specifically rated by any credit agency, it is difficult to specifically attribute changes in our estimate of the applicable credit risk adjusted spread to specific changes in our own creditworthiness versus changes in the market's required return from similar companies. As a result, these considerations must be largely based off of qualitative considerations as we do not have a credit rating and we do not regularly issue senior or subordinated debt that would provide us an independent measure of the changes in how the market quantifies our perceived default risk.

On a quarterly basis we assess entity-specific qualitative considerations that if not mitigated or represents a material change from the prior reporting period may result in a change to the perceived creditworthiness and ultimately the estimated credit risk adjusted spread utilized to value these liabilities. Entity-specific considerations that positively impact our creditworthiness include: our strong capital position resulting from our successful public stock offerings in 2009 and 2010 that offers us flexibility to pursue business opportunities such as mergers and acquisitions, or expand our footprint and product offerings; having significant levels of on and off-balance sheet liquidity; being profitable (after excluding the one-time goodwill impairment charge recognized in 2009); and, having an experienced management team. However, these positive considerations are mitigated by significant risks and uncertainties that impact our creditworthiness and ability to maintain capital adequacy in the future. Specific risks and concerns include: given our concentration of loans secured by real estate in our loan portfolio, a continued and sustained deterioration of the real estate market may result in declines in the value of the underlying collateral and increased delinquencies that could result in an increased of charge-offs; despite recent improvement, our credit quality metrics remain negatively elevated since 2007 relative to historical standards; the continuation of current economic downturn that has been particularly severe in our primary markets could adversely affect our business; recent increased regulation facing our industry, such as the Emergency Economic Stabilization Act of 2008, the American Recovery and Reinvestment Act of 2009 and the Dodd-Frank Act, will increase the cost of compliance and restrict our ability to conduct business consistent with historical practices, and could negatively impact profitability; we have a significant amount of goodwill and other intangible assets that dilute our available tangible common equity; and the carrying value of certain material, recently recorded assets on our balance sheet, such as the FDIC loss-sharing indemnification asset, are highly reliant on management estimates, such as the timing or amount of losses that are estimated to be covered, and the assumed continued compliance with the provisions of the applicable loss-share agreement. To the extent assumptions ultimately prove incorrect or should we consciously forego or unknowingly violate the guidelines of the agreement, an impairment of the asset may result which would reduce capital.

Additionally, the Company periodically utilizes an external valuation firm to determine or validate the reasonableness of the assessments of inputs and factors that ultimately determines the estimated fair value of these liabilities. The extent we involve or engage these external third parties correlates to management's assessment of the current subordinated debt market, how the current environment and market compares to the preceding quarter, and perceived changes in the Company's own creditworthiness during the quarter. In periods of potential significant valuation changes and at year-end reporting periods we typically engage third parties to perform a full independent valuation of these liabilities. For periods where management has assessed the market and other factors impacting the underlying valuation assumptions of these liabilities, and has determined significant changes to the valuation of these liabilities in the current period are remote, the scope of the valuation specialist's review is limited to a review the reasonableness of Management's assessment of inputs. Based on the procedures and methodology as described above, the Company has determined that the underlying inputs and assumptions have not materially changed since that last full-scope third-party valuation as of December 31, 2011.

Absent changes to the significant inputs utilized in the discounted cash flow model used to measure the fair value of these instruments at each reporting period, the cumulative discount for each junior subordinated debenture will reverse over time, ultimately returning the carrying values of these instruments to their notional values at their expected redemption dates, in a manner similar to the effective yield method as if these instruments were accounted for under the amortized cost method. This will result in recognizing losses on junior subordinated debentures carried at fair value on a quarterly basis within non-interest income. For the three months ended March 31, 2012, we recorded a loss of $548,000 and, for the three months ended March 31, 2011, we recorded a loss of $542,000 resulting from the change in fair value of the junior subordinated debentures recorded at fair value. Observable activity in the junior subordinated debenture and related markets in future periods may change the effective rate used to discount these liabilities, and could result in additional fair value adjustments (gains or losses on junior subordinated debentures measured at fair value) outside the expected periodic change in fair value had the fair value assumptions remained unchanged.

As noted above, the Dodd-Frank Act limits the ability of certain bank holding companies to treat trust preferred security debt issuances as Tier 1 capital. As the Company had less than $15 billion in assets at December 31, 2009, under the Dodd-Frank Act, the Company will be able to continue to include its existing trust preferred securities, less the common stock of the Trusts, in Tier 1 capital. At March 31, 2012, the Company's restricted core capital elements were 18.2% of total core capital, net of goodwill and any associated deferred tax liability.
