NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1 – Summary of Significant Accounting Policies 

The accounting and financial reporting policies of Umpqua Holdings Corporation conform to accounting principles generally accepted in the United States of America. The accompanying interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries.  All inter-company balances and transactions have been eliminated. The condensed consolidated financial statements have not been audited. A more detailed description of our accounting policies is included in the 2017 Annual Report filed on Form 10-K. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the 2017 Annual Report filed on Form 10-K. All references in this report to "Umpqua," "we," "our," "us," the "Company" or similar references mean Umpqua Holdings Corporation, and include our consolidated subsidiaries where the context so requires. References to "Bank" refer to our subsidiary Umpqua Bank, an Oregon state-chartered commercial bank, and references to "Umpqua Investments" refer to our subsidiary Umpqua Investments, Inc., a registered broker-dealer and investment adviser. The Bank also has a wholly-owned subsidiary, Financial Pacific Leasing Inc., a commercial equipment leasing company. Pivotus Ventures, Inc., a wholly-owned subsidiary of Umpqua Holdings Corporation, focuses on advancing bank innovation by developing new bank platforms that could have a significant impact on the experience and economics of banking.

In preparing these condensed consolidated financial statements, the Company has evaluated events and transactions subsequent to June 30, 2018 for potential recognition or disclosure. In management's opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments include normal and recurring accruals considered necessary for a fair and accurate presentation. The results for interim periods are not necessarily indicative of results for the full year or any other interim period.  

Out of Period Correction

Subsequent to the issuance of the Company's March 31, 2018 condensed consolidated financial statements, the Company's management determined that a prospective interest method versus retrospective interest method was incorrectly used to recognize income on the portfolio of residential mortgage-backed securities and collateralized mortgage obligations which has a fair value of $2.5 billion as of June 30, 2018. These securities are considered structured note securities as defined by ASC 320-10-35. Income on these securities should be recognized using the retrospective interest method. The Company has historically used the prospective method of income recognition for these securities. For other types of securities, there are other methods of income recognition allowed by the guidance. We concluded that the difference between these two methodologies is immaterial. The Company has changed to the retrospective interest method as of June 30, 2018. To reflect this change, the cumulative difference between these two methods of $7.2 million has been recognized as an out of period adjustment in the current period, resulting in a decrease in interest income on taxable investment securities and a corresponding decrease in the unrealized loss on taxable investment securities. We have concluded that this error has an immaterial impact to the results for 2018, as well as prior periods. The Company has recorded the adjustment in the quarter ended June 30, 2018, no other periods have been updated to reflect this adjustment.

Correction of Prior Period Balances

Subsequent to the issuance of the Company's March 31, 2018 condensed consolidated financial statements, the Company's management determined that the calculation and corresponding recognition of the accretion of the purchase accounting discount on the loans acquired from Sterling Financial Corporation (ASC 310-20 loans) that were not impaired was calculated in a manner that was considered to be inconsistent with accounting principals generally accepted in the United States of America as indicated in ASC 310-20. As a result, the financial statements have been restated to reflect the correction of the difference in accretion/amortization related to the loans acquired. Management believes that the effect of this restatement is not material to our previously issued consolidated financial statements.

10

As the error began in 2014, a prior period adjustment has been recorded to reflect the difference in loans and leases, as well as retained earnings in the opening period that is first reported in this 10-Q. As a result, the condensed consolidated statements of income have been revised to reflect these changes to the applicable line items as follows.

The condensed consolidated statement of comprehensive income has been updated to reflect the change in net income for the three and six months ended June 30, 2017. Comprehensive income increased by $407,000 for the three months ended June 30, 2017 to $66.0 million and by $440,000 for the six months ended June 30, 2017 to $114.5 million. The condensed consolidated statement of cash flows has also been updated to reflect these changes, resulting in an increase in cash flows from operating activities for June 30, 2017 of $717,000 to reflect the increase in net income and the change in other liabilities (deferred tax liability) and a corresponding decrease in the cash flows from investing activities of $717,000 for June 30, 2017 as part of the net change in loans and leases.

Periods not presented herein will be revised, as applicable, as they are included in future filings.

Application of new accounting guidance

As of January 1, 2018, Umpqua adopted the Financial Accounting Standard Board's ("FASB") Accounting Standard Update ("ASU") No. 2014-09, Revenue from Contracts with Customers and all subsequent amendments to the ASU (collectively "ASC 606"), which (i) creates a single framework for recognizing revenue from contracts with customers that are within its scope and (ii) revises when it is appropriate to recognize a gain or loss from the transfer of nonfinancial assets such as other real estate owned. The majority of Umpqua's revenues come from interest income and other sources, including loans, leases, securities, and derivatives, that are outside the scope of ASC 606. Umpqua's revenues that are within the scope of ASC 606 are presented within Non-Interest Income and are recognized as revenue as the Company satisfies its obligation to the customer. Revenues within the scope of ASC 606 include service charges on deposits, brokerage revenue, interchange income, and the sale of other real estate owned. Refer to Note 15 - Revenue from Contracts with Customers for further discussion of Umpqua's accounting policies for revenue sources within the scope of ASC 606.

Umpqua adopted ASC 606 using the modified retrospective method applied on all contracts not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606 while prior period amounts continue to be reported in accordance with legacy generally accepted accounting principles ("GAAP"). The adoption of ASC 606 did not result in a material change to the accounting for any of the in-scope revenue streams; as such, no cumulative effect adjustment was recorded.

As of January 1, 2018, Umpqua applied FASB ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The new guidance relates to the recognition and measurement of financial instruments. This ASU requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Upon adoption, certain equity securities were reclassified from available for sale to the equity securities classification on the balance sheet. The ASU was applied prospectively. The amendment also requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. This ASU also eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. The disclosures in the fair value footnote have been updated accordingly.

The amendment also requires a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument specific credit risk (also referred to as "own credit") when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. The Company's junior subordinated debentures are variable-rate instruments based on LIBOR, with the majority resetting quarterly. Applying the updated guidance, the FASB noted that the entire risk in excess of the risk free or benchmark rate could be considered instrument-specific credit risk. The Company has determined that all changes in fair value of the junior subordinated debentures are due to changes in value other than in the benchmark rate, and accordingly are instrument-specific credit risk. As such, the Company calculated the change in the discounted cash flows based on updated market credit spreads since the election of the fair value option for each junior subordinated debenture measured at fair value to be a net gain of $13.0 million. The gain was recorded, net of the tax effect, as a cumulative effect adjustment between retained earnings and accumulated other comprehensive income (loss), resulting in an adjustment of $9.7 million upon adoption.

For 2018, the change in fair value is attributable to the change in the instrument specific credit risk of the junior subordinated debentures, as determined by the application of ASU 2016-01. Accordingly, the loss on fair value of junior subordinated debentures for the three and six months ended June 30, 2018 of $1.5 million and $3.2 million, respectively, is recorded in other comprehensive income (loss), net of tax, as an other comprehensive loss of $1.1 million and $2.4 million, respectively.

Recent accounting pronouncements 

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) as well as additional ASUs for enhancement, clarification or transition of the new lease standard (collectively "ASC 842"). ASC 842 will require lessees, among other things, to recognize lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous authoritative guidance. This update also introduces new disclosure requirements for leasing arrangements. ASC 842 is effective for financial statements issued for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The Company has established a project team for the implementation of this new standard. The team has completed implementation of new lease software that will support the current leasing process, as well as aid in the transition to the new leasing guidance. Although an estimate of the impact of the new leasing standard has not yet been determined, the Company expects a significant new lease asset and related lease liability on the balance sheet due to the number of leased properties the Bank currently has that are accounted for under current operating lease guidance.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments —Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires the measurement of all expected credit losses for certain financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates, but will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. The ASU requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization's portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application will be permitted for specified periods. The Company has an established cross-functional team and project management governance process in place to manage implementation of this new guidance. The team has been working on the process by vetting the data elements and implementing modeling options that are expected to be critical to the new process. An estimate of the impact of this standard has not yet been determined, however, the impact is expected to be significant.

For periods presented after December 31, 2017, equity securities are no longer classified as available for sale securities, and are instead separately disclosed on the balance sheet. As of December 31, 2017, the equity securities were reported in investments in mutual funds and other securities within available for sale investment securities. 

Investment securities that were in an unrealized loss position as of June 30, 2018 and December 31, 2017 are presented in the following tables, based on the length of time individual securities have been in an unrealized loss position.

The unrealized losses on the available for sale securities portfolio were caused by changes in market interest rates or the widening of market spreads subsequent to the initial purchase of these securities and are not due to the underlying credit of the issuers. Management monitors the securities within the portfolio, including the published credit ratings of the obligations of state and political subdivisions securities for material rating or outlook changes. As of June 30, 2018, 97% of the obligations of states and political subdivisions securities were rated A3/A- or higher by rating agencies. Substantially all of the Company's obligations of states and political subdivisions are general obligation issuances. All of the available for sale residential mortgage-backed securities and collateralized mortgage obligations portfolio in an unrealized loss position at June 30, 2018 are issued or guaranteed by government sponsored enterprises. It is expected that the mortgage-backed securities and collateralized mortgage obligations securities will be settled at a price at least equal to the amortized cost of each investment.

Because the decline in fair value of the available for sale securities portfolio is attributable to changes in interest rates or widening market spreads and not credit quality, and because the Bank does not intend to sell the securities and it is not more likely than not that the Bank will be required to sell these securities before recovery of their amortized cost basis, which may include holding each security until maturity, these investments are not considered other-than-temporarily impaired. 

The following table presents the contractual maturities of investment securities at June 30, 2018:

Note 4– Allowance for Loan and Lease Loss and Credit Quality 

The Bank's methodology for assessing the appropriateness of the Allowance for Loan and Lease Loss ("ALLL") consists of three key elements: 1) the formula allowance; 2) the specific allowance; and 3) the unallocated allowance. By incorporating these factors into a single allowance requirement analysis, we believe all risk-based activities within the loan and lease portfolios are simultaneously considered. 

Formula Allowance 

When loans and leases are originated or acquired, they are assigned a risk rating that is reassessed periodically during the term of the loan or lease through the credit review process.  The Bank's risk rating methodology assigns risk ratings ranging from 1 to 10, where a higher rating represents higher risk. The 10 risk rating categories are a primary factor in determining an appropriate amount for the formula allowance. 

The formula allowance is calculated by applying risk factors to various segments of pools of outstanding loans and leases. Risk factors are assigned to each portfolio segment based on management's evaluation of the losses inherent within each segment. Segments with greater risk of loss will therefore be assigned a higher risk factor. 

Base risk – The portfolio is segmented into loan categories, and these categories are assigned a Base risk factor based on an evaluation of the loss inherent within each segment. 

Extra risk – Additional risk factors provide for an additional allocation of ALLL based on the loan and lease risk rating system and loan delinquency, and reflect the increased level of inherent losses associated with more adversely classified loans and leases. 

Risk factors may be changed periodically based on management's evaluation of the following factors: loss experience; changes in the level of non-performing loans and leases; regulatory exam results; changes in the level of adversely classified loans and leases; improvement or deterioration in economic conditions; and any other factors deemed relevant. Additionally, Financial Pacific Leasing Inc. considers additional quantitative and qualitative factors:  migration analysis; a static pool analysis of historic recoveries; and forecasting uncertainties. A migration analysis is a technique used to estimate the likelihood that an account will progress through the various delinquency states and ultimately be charged off.

17

Specific Allowance 

Regular credit reviews of the portfolio identify loans that are considered potentially impaired. Potentially impaired loans are referred to the ALLL Committee which reviews and approves designated loans as impaired. A loan is considered impaired when, based on current information and events, we determine that we will probably not be able to collect all amounts due according to the loan contract, including scheduled interest payments. When we identify a loan as impaired, we measure the impairment using discounted cash flows or estimated note sale price, except when the sole remaining source of the repayment for the loan is the liquidation of the collateral. In these cases, we use the current fair value of the collateral, less selling costs, instead of discounted cash flows. If we determine that the value of the impaired loan is less than the recorded investment in the loan, we either recognize an impairment reserve as a specific allowance to be provided for in the allowance for loan and lease losses or charge-off the impaired balance on collateral-dependent loans if it is determined that such amount represents a confirmed loss.  Loans determined to be impaired are excluded from the formula allowance so as not to double-count the loss exposure.

The combination of the formula allowance component and the specific allowance component represents the allocated allowance for loan and lease losses. There was no unallocated allowance as of June 30, 2018 and December 31, 2017.

Management believes that the ALLL was adequate as of June 30, 2018. There is, however, no assurance that future loan and lease losses will not exceed the levels provided for in the ALLL and could possibly result in additional charges to the provision for loan and lease losses.

The reserve for unfunded commitments ("RUC") is established to absorb inherent losses associated with our commitment to lend funds, such as with a letter or line of credit. The adequacy of the ALLL and RUC are monitored on a regular basis and are based on management's evaluation of numerous factors. These factors include the quality of the current loan portfolio; the trend in the loan portfolio's risk ratings; current economic conditions; loan concentrations; loan growth rates; past-due and non-performing trends; evaluation of specific loss estimates for all significant problem loans; historical charge-off and recovery experience; and other pertinent information.

There have been no significant changes to the Bank's ALLL methodology or policies in the periods presented.

Asset Quality and Non-Performing Loans and Leases

We manage asset quality and control credit risk through diversification of the loan and lease portfolio and the application of policies designed to promote sound underwriting and loan and lease monitoring practices. The Bank's Credit Quality Administration is charged with monitoring asset quality, establishing credit policies and procedures and enforcing the consistent application of these policies and procedures across the Bank.  Reviews of non-performing, past due loans and leases and larger credits, designed to identify potential charges to the allowance for loan and lease losses, and to determine the adequacy of the allowance, are conducted on an ongoing basis. These reviews consider such factors as the financial strength of borrowers, the value of the applicable collateral, loan and lease loss experience, estimated loan and lease losses, growth in the loan and lease portfolio, prevailing economic conditions and other factors.

Impaired Loans 

Loans with no related allowance reported generally represent non-accrual loans, which are also considered impaired loans. The Bank recognizes the charge-off on impaired loans in the period it arises for collateral-dependent loans.  Therefore, the non-accrual loans as of June 30, 2018 have already been written down to their estimated net realizable value and are expected to be resolved with no additional material loss, absent further decline in net realizable value.  The valuation allowance on impaired loans primarily represents the impairment reserves on performing restructured loans, and is measured by comparing the present value of expected future cash flows on the restructured loans discounted at the interest rate of the original loan agreement to the loan's carrying value.

Credit Quality Indicators 

As previously noted, the Bank's risk rating methodology assigns risk ratings ranging from 1 to 10, where a higher rating represents higher risk.  The Bank differentiates its lending portfolios into homogeneous loans and leases and non-homogeneous loans and leases. Homogeneous loans and leases are not risk rated until they are greater than 30 days past due, and risk rating is based on the past due status of the loan or lease. The 10 risk rating categories can be generally described by the following groupings for loans and leases:

Minimal Risk—A minimal risk loan or lease, risk rated 1, is to a borrower of the highest quality. The borrower has an unquestioned ability to produce consistent profits and service all obligations and can absorb severe market disturbances with little or no difficulty. 

24

Low Risk—A low risk loan or lease, risk rated 2, is similar in characteristics to a minimal risk loan.  Margins may be smaller or protective elements may be subject to greater fluctuation. The borrower will have a strong demonstrated ability to produce profits, provide ample debt service coverage and to absorb market disturbances. 

Modest Risk—A modest risk loan or lease, risk rated 3, is a desirable loan or lease with excellent sources of repayment and no currently identifiable risk associated with collection. The borrower exhibits a very strong capacity to repay the credit in accordance with the repayment agreement. The borrower may be susceptible to economic cycles, but will have reserves to weather these cycles. 

Average Risk—An average risk loan or lease, risk rated 4, is an attractive loan or lease with sound sources of repayment and no material collection or repayment weakness evident. The borrower has an acceptable capacity to pay in accordance with the agreement. The borrower is susceptible to economic cycles and more efficient competition, but should have modest reserves sufficient to survive all but the most severe downturns or major setbacks.

Acceptable Risk—An acceptable risk loan or lease, risk rated 5, is a loan or lease with lower than average, but still acceptable credit risk. These borrowers may have higher leverage, less certain but viable repayment sources, have limited financial reserves and may possess weaknesses that can be adequately mitigated through collateral, structural or credit enhancement. The borrower is susceptible to economic cycles and is less resilient to negative market forces or financial events. Reserves may be insufficient to survive a modest downturn. 

Watch—A watch loan or lease, risk rated 6, is still pass-rated, but represents the lowest level of acceptable risk due to an emerging risk element or declining performance trend. Watch ratings are expected to be temporary, with issues resolved or manifested to the extent that a higher or lower rating would be appropriate. The borrower should have a plausible plan, with reasonable certainty of success, to correct the problems in a short period of time.

Special Mention—A special mention loan or lease, risk rated 7, has potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or the institution's credit position at some future date. They contain unfavorable characteristics and are generally undesirable. Loans and leases in this category are currently protected but are potentially weak and constitute an undue and unwarranted credit risk, but not to the point of a substandard classification. A special mention loan or lease has potential weaknesses, which if not checked or corrected, weaken the asset or inadequately protect the Bank's position at some future date. For commercial and commercial real estate homogeneous loans and leases to be classified as special mention, risk rated 7, the loan or lease is greater than 30 to 59 days past due from the required payment date at month-end. Residential and consumer and other homogeneous loans are risk rated 7, when the loan is greater than 30 to 89 days past due from the required payment date at month-end. 

Substandard—A substandard asset, risk rated 8, is inadequately protected by the current worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified substandard. Loans and leases are classified as substandard when they have unsatisfactory characteristics causing unacceptable levels of risk. A substandard loan or lease normally has one or more well-defined weaknesses that could jeopardize repayment of the debt. The likely need to liquidate assets to correct the problem, rather than repayment from successful operations is the key distinction between special mention and substandard. Commercial and commercial real estate homogeneous loans and leases are classified as a substandard loan or lease, risk rated 8, when the loan or lease is 60 to 89 days past due from the required payment date at month-end. Residential and consumer and other homogeneous loans are classified as a substandard loan, risk rated 8, when an open-end loan is 90 to 180 days past due from the required payment date at month-end or when a closed-end loan 90 to 120 days is past due from the required payment date at month-end.

25

Doubtful—Loans or leases classified as doubtful, risk rated 9, have all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors, which may work towards strengthening of the asset, classification as a loss (and immediate charge-off) is deferred until more exact status may be determined. Pending factors include proposed merger, acquisition, liquidation procedures, capital injection, and perfection of liens on additional collateral and refinancing plans. In certain circumstances, a doubtful rating will be temporary, while the Bank is awaiting an updated collateral valuation. In these cases, once the collateral is valued and appropriate margin applied, the remaining un-collateralized portion will be charged-off. The remaining balance, properly margined, may then be upgraded to substandard, however must remain on non-accrual.  Commercial and commercial real estate homogeneous doubtful loans or leases, risk rated 9, are 90 to 179 days past due from the required payment date at month-end. 

Loss—Loans or leases classified as loss, risk rated 10, are considered un-collectible and of such little value that the continuance as an active Bank asset is not warranted. This rating does not mean that the loan or lease has no recovery or salvage value, but rather that the loan or lease should be charged-off now, even though partial or full recovery may be possible in the future. For a commercial or commercial real estate homogeneous loss loan or lease to be risk rated 10, the loan or lease is 180 days and more past due from the required payment date. These loans are generally charged-off in the month in which the 180 day time period elapses. Residential, consumer and other homogeneous loans are risk rated 10, when a loan becomes past due 120 cumulative days from the contractual due date.  Residential and consumer loans secured by real estate are generally charged down to net realizable value in the month in which the loan becomes 180 days past due. All other residential, consumer, and other homogeneous loans are generally charged-off in the month in which the 120 day period elapses. 

Impaired—Loans are classified as impairedwhen, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal and interest when due, in accordance with the terms of the original loan agreement, without unreasonable delay. This generally includes all loans classified as non-accrual and troubled debt restructurings. Impaired loans are risk rated for internal and regulatory rating purposes, but presented separately for clarification.

(1) The percentage of impaired loans classified as pass/watch and substandard was 1.7%, and 98.3%, respectively, as of December 31, 2017.

(2) Includes government guaranteed GNMA mortgage loans that Umpqua has the right but not the obligation to repurchase that are past due 90 days or more, totaling $12.4 million at December 31, 2017, which is included in the substandard category.

Troubled Debt Restructurings 

At June 30, 2018 and December 31, 2017, impaired loans of $27.2 million and $32.2 million, respectively, were classified as accruing restructured loans. The restructurings were granted in response to borrower financial difficulty, and generally provide for a temporary modification of loan repayment terms. In order for a newly restructured loan to be considered for accrual status, the loan's collateral coverage generally will be greater than or equal to 100% of the loan balance, the loan is current on payments, and the borrower must either prefund an interest reserve or demonstrate the ability to make payments from a verified source of cash flow. Impaired restructured loans carry a specific allowance and the allowance on impaired restructured loans is calculated consistently across the portfolios. 

There were $537,000 in available commitments for troubled debt restructurings outstanding as of June 30, 2018 and $917,000 as of December 31, 2017. 

The following tables present troubled debt restructurings by accrual versus non-accrual status and by loan class as of June 30, 2018 and December 31, 2017:

Residential, net	6,687		—		6,687
Total, net of deferred fees and costs	$	32,168	$	22,066	$	54,234

The Bank's policy is that loans placed on non-accrual will typically remain on non-accrual status until all principal and interest payments are brought current and the prospect for future payment in accordance with the loan agreement appears relatively certain.  The Bank's policy generally refers to six months of payment performance as sufficient to warrant a return to accrual status.

There were no new restructured loans during the three months ended June 30, 2018. The following tables present newly restructured loans that occurred during the six months ended June 30, 2018 and the three and six months ended June 30, 2017:

For the periods presented in the tables above, the outstanding recorded investment was the same pre and post modification. There were $10.2 million in financing receivables modified as troubled debt restructurings within the previous 12 months for which there was a payment default during the six months ended June 30, 2018. There were $118,000 in financing receivables modified as troubled debt restructurings within the previous 12 months for which there was a payment default during the six months endedJune 30, 2017. There were none in the three months ended June 30, 2018 and 2017.

Note 5–Goodwill and Other Intangible Assets

Goodwill totaled $1.8 billion at both June 30, 2018 and December 31, 2017, and represents the excess of the total acquisition price paid over the fair value of the assets acquired, net of the fair values of liabilities assumed. Goodwill is not amortized but is evaluated for impairment on an annual basis at December 31 of each year or whenever events or changes in circumstances indicate the carrying value may not be recoverable. No events or circumstances since the December 31, 2017 annual impairment test were noted that would indicate it was more likely than not a goodwill impairment exists.

The following table summarizes the changes in the Company's other intangible assets for the year ended December 31, 2017, and the six months ended June 30, 2018.

(in thousands)	Other Intangible Assets
	Gross		Accumulated Amortization			Net
Balance, December 31, 2016	$	113,471	$	(76,585	)	$	36,886

Core deposit intangible asset values were determined by an analysis of the cost differential between the core deposits inclusive of estimated servicing costs and alternative funding sources for core deposits acquired through acquisitions. The core deposit intangible assets recorded are amortized on an accelerated basis over a period of approximately 10 years. No impairment losses separate from the scheduled amortization have been recognized in the periods presented.

(1) Principally reflects changes in discount rates and prepayment speed assumptions, which are primarily affected by changes in interest rates. 

(2) Represents changes due to collection/realization of expected cash flows over time.

Information related to our serviced loan portfolio as of June 30, 2018 and December 31, 2017 is as follows: 

(dollars in thousands)	June 30, 2018			December 31, 2017
Balance of loans serviced for others	$	15,508,182		$	15,336,597
MSR as a percentage of serviced loans	1.07		%	1.00		%

The amount of contractually specified servicing fees, late fees and ancillary fees earned, recorded in residential mortgage banking revenue, was $10.4 million and $20.9 million for the three and six months ended June 30, 2018, respectively, as compared to $9.8 million and $19.7 million for the three and six month ended June 30, 2017, respectively. 

Key assumptions used in measuring the fair value of MSR as of June 30, 2018 and December 31, 2017 were as follows: 

	June 30, 2018		December 31, 2017
Constant prepayment rate	11.75	%	12.27	%
Discount rate	9.69	%	9.70	%
Weighted average life (years)	6.6		6.3

A sensitivity analysis of the current fair value to changes in discount and prepayment speed assumptions as of June 30, 2018 and December 31, 2017 is as follows:

(in thousands)	June 30, 2018			December 31, 2017
Constant prepayment rate
Effect on fair value of a 10% adverse change	$	(6,675	)	$	(6,290	)
Effect on fair value of a 20% adverse change	$	(12,853	)	$	(12,093	)
Discount rate
Effect on fair value of a 100 basis point adverse change	$	(6,745	)	$	(5,840	)
Effect on fair value of a 200 basis point adverse change	$	(12,974	)	$	(11,249	)

The sensitivity analysis presents the hypothetical effect on fair value of the MSR. The effect of such hypothetical change in assumptions generally cannot be extrapolated because the relationship of the change in an assumption to the change in fair value is not linear. Additionally, in the analysis, the impact of an adverse change in one assumption is calculated independent of any impact on other assumptions. In reality, changes in one assumption may change another assumption.

(1) Includes acquisition accounting adjustments, net of accumulated amortization, for junior subordinated debentures assumed in connection with previous mergers as well as fair value adjustments related to trusts recorded at fair value. 

(2) Contractual interest rate of junior subordinated debentures. 

(3) Effective interest rate based upon the carrying value as of June 30, 2018. 

31

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 $14.0 million at June 30, 2018 and $14.3 million at December 31, 2017. As of June 30, 2018, all of the junior subordinated debentures were redeemable at par, at their applicable quarterly or semiannual interest payment dates.

In the first quarter of 2018, the Company paid $10.6 million to redeem the debt securities of the Humboldt Bancorp Statutory Trust I and HB Capital Trust I.

The Company has elected the fair value measurement option for junior subordinated debentures originally issued by the Company (the Umpqua Statutory Trusts) and for junior subordinated debentures acquired from Sterling.

The fair value of the junior subordinated debentures increased for the three and six months ended June 30, 2018, however, based on the application of ASU 2016-01, no loss was recorded in earnings. Instead the loss of $1.5 million and $3.2 million for the three and six months ended, respectively, was recorded in other comprehensive income (loss), net of tax. The loss recorded in earnings resulting from the change in the fair value of these instruments was $1.6 million and $3.1 million for the three and six months ended June 30, 2017, respectively.

Note 8 – Commitments and Contingencies 

Lease Commitments — As of June 30, 2018, the Bank leased 221 sites under non-cancelable operating leases. The leases contain various provisions for increases in rental rates, based either on changes in the published Consumer Price Index or a predetermined escalation schedule. Substantially all of the leases provide the Company with the option to extend the lease term one or more times following expiration of the initial term. 

Rent expense for the three and six months ended June 30, 2018 was $9.4 million and $19.0 million, respectively, and for the three and six months ended June 30, 2017 was $9.5 million and $19.2 million, respectively. Rent expense was partially offset by rent income of $648,000 and $1.3 million for the three and six months ended June 30, 2018, respectively, and $494,000 and $1.0 million for the three and six months ended June 30, 2017, respectively.

Financial Instruments with Off-Balance-Sheet Risk — The Company's financial statements do not reflect various commitments and contingent liabilities that arise in the normal course of the Bank's business and involve elements of credit, liquidity, and interest rate risk. 

The following table presents a summary of the Bank's commitments and contingent liabilities:  

(in thousands)	As of June 30, 2018
Commitments to extend credit	$	5,008,398
Forward sales commitments	$	639,160
Commitments to originate residential mortgage loans held for sale	$	338,695
Standby letters of credit	$	69,181

The Bank is a party to financial instruments with off-balance-sheet credit risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and financial guarantees. Those instruments involve elements of credit and interest-rate risk similar to the risk involved in on-balance sheet items recognized in the Condensed Consolidated Balance Sheets. The contract or notional amounts of those instruments reflect the extent of the Bank's involvement in particular classes of financial instruments. 

The Bank's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit, and financial guarantees written, is represented by the contractual notional amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. 

32

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any covenant or condition established in the applicable contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. While most standby letters of credit are not utilized, a significant portion of such utilization is on an immediate payment basis. The Bank evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if it is deemed necessary by the Bank upon extension of credit, is based on management's credit evaluation of the counterparty. Collateral varies but may include cash, accounts receivable, inventory, premises and equipment and income-producing commercial properties. 

Standby letters of credit and written financial guarantees are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. These guarantees are primarily issued to support public and private borrowing arrangements, including international trade finance, commercial paper, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank holds cash, marketable securities, or real estate as collateral supporting those commitments for which collateral is deemed necessary. There were no financial guarantees in connection with standby letters of credit that the Bank was required to perform on during the three and six months ended June 30, 2018 and June 30, 2017. At June 30, 2018, approximately $43.0 million of standby letters of credit expire within one year, and $26.2 million expire thereafter. The Bank recorded approximately $227,000 and $339,000 in fees associated with standby letters of credit during the three and six months ended June 30, 2018, respectively, compared to $310,000 and $464,000 for the three and six months ended June 30, 2017, respectively.  

Residential mortgage loans sold into the secondary market are sold with limited recourse against the Company, meaning that the Company may be obligated to repurchase or otherwise reimburse the investor for incurred losses on any loans that suffer an early payment default, are not underwritten in accordance with investor guidelines or are determined to have pre-closing borrower misrepresentations. As of June 30, 2018, the Company had a residential mortgage loan repurchase reserve liability of $1.3 million. For loans sold to GNMA, the Bank has a unilateral right, but not the obligation, to repurchase loans that are past due 90 days or more. As of June 30, 2018, the Bank has recorded a liability for the loans subject to this repurchase right of $9.2 million, and has recorded these loans as part of the loan portfolio as if we had repurchased these loans.

Legal Proceedings—Umpqua is involved in legal proceedings occurring in the ordinary course of business. Based on information currently available, advice of counsel and available insurance coverage, we believe that the eventual outcome of actions against the Company or its subsidiaries will not, individually or in the aggregate, have a material adverse effect on our consolidated financial condition. However, it is possible that the ultimate resolution of a matter, if unfavorable, may be material to our results of operations for any particular period.

Concentrations of Credit Risk— The Bank grants real estate mortgage, real estate construction, commercial, agricultural and installment loans and leases to customers throughout Oregon, Washington, California, Idaho, and Nevada. In management's judgment, a concentration exists in real estate-related loans, which represented approximately 75% of the Bank's loan and lease portfolio at June 30, 2018 and December 31, 2017.  Commercial real estate concentrations are managed to assure wide geographic and business diversity. Although management believes such concentrations have no more than the normal risk of collectability, a substantial decline in the economy in general, material increases in interest rates, changes in tax policies, tightening credit or refinancing markets, or a decline in real estate values in the Bank's primary market areas in particular, could have an adverse impact on the repayment of these loans.  Personal and business incomes, proceeds from the sale of real property, or proceeds from refinancing, represent the primary sources of repayment for a majority of these loans. 

The Bank recognizes the credit risks inherent in dealing with other depository institutions. Accordingly, to prevent excessive exposure to any single correspondent, the Bank has established general standards for selecting correspondent banks as well as internal limits for allowable exposure to any single correspondent. In addition, the Bank has an investment policy that sets forth limitations that apply to all investments with respect to credit rating and concentrations with an issuer.

Note 9– Derivatives 

The Bank may use derivatives to hedge the risk of changes in the fair values of interest rate lock commitments and residential mortgage loans held for sale. None of the Company's derivatives are designated as hedging instruments.  Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in income. The Company primarily utilizes forward interest rate contracts in its derivative risk management strategy. 

33

The Bank enters into forward delivery contracts to sell residential mortgage loans or mortgage-backed securities to broker/dealers at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential mortgage loan commitments.  Credit risk associated with forward contracts is limited to the replacement cost of those forward contracts in a gain position.  There were no counterparty default losses on forward contracts in the three and six months ended June 30, 2018 and 2017.  Market risk with respect to forward contracts arises principally from changes in the value of contractual positions due to changes in interest rates. The Bank limits its exposure to market risk by monitoring differences between commitments to customers and forward contracts with broker/dealers. In the event the Company has forward delivery contract commitments in excess of available mortgage loans, the Company completes the transaction by either paying or receiving a fee to or from the broker/dealer equal to the increase or decrease in the market value of the forward contract. At June 30, 2018, the Bank had commitments to originate mortgage loans held for sale totaling $338.7 million and forward sales commitments of $639.2 million, which are used to hedge both on-balance sheet and off-balance sheet exposures. 

The Bank executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies.  Those interest rate swaps are simultaneously hedged by offsetting the interest rate swaps that the Bank executes with a third party, such that the Bank minimizes its net risk exposure. As of June 30, 2018, the Bank had 707 interest rate swaps with an aggregate notional amount of $3.5 billion related to this program.  As of December 31, 2017, the Bank had 653 interest rate swaps with an aggregate notional amount of $3.0 billion related to this program.

At both June 30, 2018 and December 31, 2017, the termination value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $29.4 million and $7.2 million, respectively.  The Bank has collateral posting requirements for initial margins with its clearing members and clearing houses and has posted collateral against its obligations under these agreements of $34.8 million and $28.2 million as of June 30, 2018 and December 31, 2017, respectively. 

Umpqua's interest rate swap derivatives are cleared through the Chicago Mercantile Exchange and London Clearing House. These clearing houses characterize the variation margin payments, for derivative contracts that are referred to as settled-to-market, as settlements of the derivative's mark-to-market exposure and not collateral. Umpqua accounts for the variation margin as an adjustment to our cash collateral, as well as a corresponding adjustment to our derivative asset and liability. As ofJune 30, 2018, the variation margin adjustment was a positive adjustment of $16.6 million as compared to a negative adjustment of $20.5 million at December 31, 2017.

The Bank incorporates credit valuation adjustments ("CVA") to appropriately reflect nonperformance risk in the fair value measurement of its derivatives. As of June 30, 2018 and December 31, 2017, the net CVA decreased the settlement values of the Bank's net derivative assets by $213,000 and $1.7 million, respectively. Various factors impact changes in the CVA over time, including changes in the credit spreads of the parties to the contracts, as well as changes in market rates and volatilities, which affect the total expected exposure of the derivative instruments.

The Bank also executes foreign currency hedges as a service for customers. These foreign currency hedges are then offset with hedges with other third-party banks to limit the Bank's risk exposure.

As of June 30, 2018, there was no unrecognized compensation cost related to nonvested stock options or nonvested restricted stock units.  As of June 30, 2018, there was $13.0 million of total unrecognized compensation cost related to nonvested restricted stock awards which is expected to be recognized over a weighted-average period of 1.82 years, assuming expected performance and market conditions are met for certain awards.

For the three and six months ended June 30, 2018, the Company received income tax benefits of $384,000 and $3.0 million, respectively, as compared to the three and six months ended June 30, 2017 of $554,000 and $2.4 million, respectively, related to the exercise of non-qualified employee stock options, disqualifying dispositions on the exercise of incentive stock options, the vesting of restricted shares and the vesting of restricted stock units. The tax deficiency or benefit is recorded as income tax expense or benefit in the period the shares are vested.

Note 11– Income Taxes 

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, as well as in the majority of states and in Canada. As of June 30, 2018, the Company has a net deferred tax liability of $27.3 million, which includes $2.5 million of state net operating loss ("NOL") carry-forwards and $2.0 million of state tax credit carry-forwards. The state NOL carry-forwards expire in tax years 2029-2031 and the state tax credit carry-forwards expire in tax years 2023-2025. The Company believes that it is more likely than not that the benefit from only certain state NOL carry-forwards will not be realized and therefore has provided a valuation allowance of $1.1 million against the deferred tax assets relating to these NOL carry-forwards. 

The Company had gross unrecognized tax benefits of $3.1 million as of June 30, 2018.  If recognized, the unrecognized tax benefit would reduce the 2018 annual effective tax rate by 0.5%. During the three and six months ended June 30, 2018, the Company accrued $5,000 and $30,000 of interest relating to its liability for unrecognized tax benefits.  Interest on unrecognized tax benefits is reported by the Company as a component of tax expense.  As of June 30, 2018, the accrued interest related to unrecognized tax benefits was $383,000.

The Company's consolidated effective tax rate as a percentage of pre-tax income for the three and six months ended June 30, 2018 was 24.7% and 24.3%, respectively, as compared to 35.8% and 36.2% for the three and six months ended June 30, 2017, respectively. The decrease is due to the reduction in the federal income tax rate due to the passage of the Tax Cuts and Jobs Act of 2017.

Note 12– Earnings Per Common Share

Nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are participating securities and are included in the computation of earnings per share pursuant to the two-class method.  The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Certain of the Company's nonvested restricted stock awards qualify as participating securities. 

Net earnings is allocated between the common stock and participating securities pursuant to the two-class method.  Basic earnings per common share is computed by dividing net earnings available to common shareholders by the weighted average number of common shares outstanding during the period, excluding participating nonvested restricted shares. 

Diluted earnings per common share is computed in a similar manner, except that first the denominator is increased to include the number of additional common shares that would have been outstanding if potentially dilutive common shares, excluding the participating securities, were issued using the treasury stock method. For all periods presented, stock options, restricted stock awards and restricted stock units are the only potentially dilutive non-participating instruments issued by the Company.  Next, we determine and include in diluted earnings per common share calculation the more dilutive effect of the participating securities using the treasury stock method or the two-class method. Undistributed losses are not allocated to the nonvested share-based payment awards (the participating securities) under the two-class method as the holders are not contractually obligated to share in the losses of the Company.

Note 13– Segment Information 

The Company reports four primary segments: Commercial Bank, Wealth Management, Retail Bank, and Home Lending with the remainder as Corporate and other.

The Commercial Bank segment includes lending, treasury and cash management services and customer risk management products to small businesses, middle market and larger commercial customers and includes the operations of Financial Pacific Leasing Inc., a commercial leasing company. The Wealth Management segment consists of the operations of Umpqua Investments, which offers a full range of retail brokerage and investment advisory services and products to its clients who consist primarily of individual investors, and Umpqua Private Bank, which serves high net worth individuals with liquid investable assets and provides customized financial solutions and offerings. The Retail Bank segment includes retail lending and deposit services for customers served through the Bank's store network. The Home Lending segment originates, sells and services residential mortgage loans. The Corporate and other segment includes activities that are not directly attributable to one of the four principal lines of business and includes the operations of Pivotus Ventures, Inc. and the parent company, eliminations and the economic impact of certain assets, capital and support functions not specifically identifiable within the other lines of business.

Management monitors the Company's results using an internal performance measurement accounting system, which provides line of business results and key performance measures. The application and development of these management reporting methodologies is a dynamic process and is subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable segment may be periodically revised retrospectively, if material.

The provision for income taxes is allocated to business segments using a 25% effective tax rate for 2018 and 37% for 2017. The residual income tax expense or benefit arising from tax planning strategies or other tax attributes to arrive at the consolidated effective tax rate is retained in Corporate and Other.

The following methods were used to estimate the fair value of each class of financial instrument that are carried at fair value in the tables above: 

Securities— Fair values for investment securities are based on quoted market prices when available or through the use of alternative approaches, such as matrix or model pricing, or broker indicative bids, when market quotes are not readily accessible or available. Management periodically reviews the pricing information received from the third-party pricing service and compares it to a secondary pricing service, evaluating significant price variances between services to determine an appropriate estimate of fair value to report.

Loans Held for Sale— Fair value for residential mortgage loans originated as held for sale is determined based on quoted secondary market prices for similar loans, including the implicit fair value of embedded servicing rights.

Residential Mortgage Servicing Rights— The fair value of MSR is estimated using a discounted cash flow model. Assumptions used include market discount rates, anticipated prepayment speeds, delinquency and foreclosure rates, and ancillary fee income net of servicing costs. This model is periodically validated by an independent model validation group. The model assumptions and the MSR fair value estimates are also compared to observable trades of similar portfolios as well as to MSR broker valuations and industry surveys, as available. Management believes the significant inputs utilized are indicative of those that would be used by market participants. 

43

Junior Subordinated Debentures— The fair value of junior subordinated debentures is estimated using an income approach valuation technique.  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. The Company periodically utilizes a valuation firm to determine or validate the reasonableness of inputs and factors that are used to determine the fair value. 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.  Due to credit concerns in the capital markets and inactivity in the trust preferred markets that have limited the observability of market spreads, we have classified this as a Level 3 fair value measure.  

Derivative Instruments— The fair value of the interest rate lock commitments and forward sales commitments are estimated using quoted or published market prices for similar instruments, adjusted for factors such as pull-through rate assumptions based on historical information, where appropriate.  The pull-through rate assumptions are considered Level 3 valuation inputs and are significant to the interest rate lock commitment valuation; as such, the interest rate lock commitment derivatives are classified as Level 3. The fair value of the interest rate swaps is determined using a discounted cash flow technique incorporating credit valuation adjustments to reflect nonperformance risk in the measurement of fair value. Although the Bank has determined that the majority of the inputs used to value its interest rate swap derivatives fall within Level 2 of the fair value hierarchy, the CVA associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of June 30, 2018, the Bank has assessed the significance of the impact of the CVA on the overall valuation of its interest rate swap positions and has determined that the CVA are not significant to the overall valuation of its interest rate swap derivatives. As a result, the Bank has classified its interest rate swap derivative valuations in Level 2 of the fair value hierarchy.   

Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs (Level 3) 

The following table provides a description of the valuation technique, significant unobservable inputs, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring basis at June 30, 2018: 

Financial Instrument	Valuation Technique	Unobservable Input	Weighted Average
Residential mortgage servicing rights	Discounted cash flow
		Constant Prepayment Rate	11.75%
		Discount Rate	9.69%
Interest rate lock commitment	Internal Pricing Model
		Pull-through rate	88.92%
Junior subordinated debentures	Discounted cash flow
		Credit Spread	4.97%

Generally, any significant increases in the constant prepayment rate and discount rate utilized in the fair value measurement of the residential mortgage servicing rights will result in negative fair value adjustments (and a decrease in the fair value measurement). Conversely, a decrease in the constant prepayment rate and discount rate will result in a positive fair value adjustment (and increase in the fair value measurement).

An increase in the pull-through rate utilized in the fair value measurement of the interest rate lock commitment derivative will result in positive fair value adjustments (and an increase in the fair value measurement). Conversely, a decrease in the pull-through rate will result in a negative fair value adjustment (and a decrease in the fair value measurement).

Management believes that the credit risk adjusted spread utilized in the fair value measurement of the junior subordinated debentures carried at fair value is indicative of the nonperformance risk premium a willing market participant would require under current market conditions, that is, the inactive market. Management attributes the change in fair value of the junior subordinated debentures during the period to market changes in the nonperformance expectations and pricing of this type of debt. The widening of the credit risk adjusted spread above the Company's contractual spreads has primarily contributed to the positive fair value adjustments.  Future contractions in the instrument-specific credit risk adjusted spread relative to the spread currently utilized to measure the Company's junior subordinated debentures at fair value as of June 30, 2018, or the passage of time, will result in negative fair value adjustments.  Generally, an increase in the credit risk adjusted spread and/or the forward swap interest rate curve will result in positive fair value adjustments (and decrease the fair value measurement). Conversely, a decrease in the credit risk adjusted spread and/or the forward swap interest rate curve will result in negative fair value adjustments (and increase the fair value measurement).

Changes in residential mortgage servicing rights carried at fair value are recorded in residential mortgage banking revenue within non-interest income. Gains (losses) on interest rate lock commitments carried at fair value are recorded in residential mortgage banking revenue within non-interest income. The contractual interest expense on the junior subordinated debentures is recorded on an accrual basis as interest on junior subordinated debentures within interest expense. Settlements related to the junior subordinated debentures represent the payment of accrued interest that is embedded in the fair value of these liabilities. 

45

For 2017, the Company recorded gains (losses) on junior subordinated debentures carried at fair value in non-interest income. As discussed in Note 1, Summary of Significant Accounting Policies, the Company applied new guidance to the accounting for the gain/loss on fair value of the junior subordinated debentures. For the three and six months ended June 30, 2018, the change in fair value is attributable to the change in the instrument specific credit risk of the junior subordinated debentures, accordingly, the losses on fair value of junior subordinated debentures for the three and six months ended June 30, 2018 of $1.5 million and $3.2 million, respectively, are recorded net of tax as an other comprehensive loss of $1.1 million and $2.4 million, respectively.

From time to time, certain assets are measured at fair value on a nonrecurring basis.  These adjustments to fair value generally result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairment, typically on collateral dependent loans. 

Fair Value of Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

The following tables present information about the Company's assets and liabilities measured at fair value on a nonrecurring basis for which a nonrecurring change in fair value has been recorded during the reporting period.  The amounts disclosed below represent the fair values at the time the nonrecurring fair value measurements were made, and not necessarily the fair value as of the dates reported upon.

The following table presents the losses resulting from nonrecurring fair value adjustments for the three and six months ended June 30, 2018 and 2017:  

(in thousands)	Three Months Ended				Six Months Ended

The following provides a description of the valuation technique and inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a nonrecurring basis. Unobservable inputs and qualitative information about the unobservable inputs are not presented as the fair value is determined by third-party information. The loans and leases amounts above represent impaired, collateral dependent loans that have been adjusted to fair value.  When we identify a collateral dependent loan as impaired, we measure the impairment using the current fair value of the collateral, less selling costs. Depending on the characteristics of a loan, the fair value of collateral is generally estimated by obtaining external appraisals, but in some cases, the value of the collateral may be estimated as having little to no value. If we determine that the value of the impaired loan is less than the recorded investment in the loan, we recognize this impairment and adjust the carrying value of the loan to fair value through the allowance for loan and lease losses.  The loss represents charge-offs or impairments on collateral dependent loans for fair value adjustments based on the fair value of collateral.

46

The other real estate owned amount above represents impaired real estate that has been adjusted to fair value.  Other real estate owned represents real estate which the Bank has taken control of in partial or full satisfaction of loans. At the time of foreclosure, other real estate owned is recorded at the lower of the carrying amount of the loan or fair value less costs to sell, which becomes the property's new basis. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for loan and lease losses. After foreclosure, management periodically performs valuations such that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Fair value adjustments on other real estate owned are recognized within net loss on real estate owned. The loss represents impairments on other real estate owned for fair value adjustments based on the fair value of the real estate. 

Fair Value Option

The following table presents the difference between the aggregate fair value and the aggregate unpaid principal balance of loans held for sale accounted for under the fair value option as of June 30, 2018 and December 31, 2017:

(in thousands)	June 30, 2018						December 31, 2017
	Fair Value		Aggregate Unpaid Principal Balance		Fair Value Less Aggregate Unpaid Principal Balance		Fair Value		Aggregate Unpaid Principal Balance		Fair Value Less Aggregate Unpaid Principal Balance
Loans held for sale	$	432,642	$	418,442	$	14,200	$	259,518	$	250,721	$	8,797

Residential mortgage loans held for sale accounted for under the fair value option are measured initially at fair value with subsequent changes in fair value recognized in earnings. Gains and losses from such changes in fair value are reported as a component of residential mortgage banking revenue, net in the Condensed Consolidated Statements of Income. For the three and six months ended June 30, 2018, the Company recorded a net increase in fair value of $5.7 million and $5.4 million, respectively. For the three and six months ended June 30, 2017, the Company recorded a net increase in fair value of $2.2 million and $7.1 million, respectively.

The Company selected the fair value measurement option for existing junior subordinated debentures (the Umpqua Statutory Trusts) and for junior subordinated debentures acquired from Sterling. The remaining junior subordinated debentures were acquired through previous business combinations and were measured at fair value at the time of acquisition and subsequently measured at amortized cost.

Accounting for the selected junior subordinated debentures 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.

Due to inactivity in the junior subordinated debenture market and the lack of 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, evaluates 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. We also consider changes in the interest rate environment in our valuation, specifically the absolute level and the shape of the slope of the forward swap curve.

(a) Not within scope of ASC 606

Deposit service charges

Umpqua earns fees from its deposit customers for account maintenance, transaction-based and overdraft services. Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis. The performance obligation is satisfied and the fees are recognized on a monthly basis as the service period is completed. Transaction-based fees on deposits accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds fees, overdraft fees, and wire fees. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer.

Debit and ATM interchange fee income and expenses

Debit and ATM interchange income represent fees earned when a debit card issued by Umpqua is used. Umpqua earns interchange fees from debit cardholder transactions through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders’ debit card. Certain expenses directly associated with the credit and debit card are recorded on a net basis with the interchange income.

48

Brokerage revenue

As of the three and six months ended June 30, 2018, Umpqua had revenues of $4.2 million and $8.4 million, respectively, for the performance of brokerage services for its clients through Umpqua Investments. Brokerage fees consist of transaction fees earned from asset management, trade execution and administrative fees from investments. Asset management fees are variable, since they are based on the underlying portfolio value, which is subject to market conditions and amounts invested by clients. Asset management fees are recognized over the period that services are provided, and when the portfolio values are known or can be estimated at the end of each quarter. Brokerage transaction fees are fixed and determinable, based on security type and trade volume, and are recognized upon trade execution. In addition, revenues are earned from selling insurance and annuity policies. The amount of revenue earned is determined by the value and type of each instrument sold and is recognized when the policy is in force.

Merchant fee income

Merchant fee income represents fees earned by Umpqua for card payment services provided to its merchant customers. Umpqua outsources these services to a third party to provide card payment services to these merchants. The third party provider passes the payments made by the merchants through to Umpqua. Umpqua, in turn, pays the third party provider for the services it provides to the merchants. These payments to the third party provider are recorded as expenses as a net reduction against fee income. In addition, a portion of the payment received represents interchange fees which are passed through to the card issuing bank. Income is primarily earned based on the dollar volume and number of transactions processed. The performance obligation is satisfied and the related fee is earned when each payment is accepted by the processing network. For the three and six months ended June 30, 2018, Umpqua had merchant processing fee revenue of $1.2 million and $2.1 million, respectively, included in other income.

Credit card and interchange income and expenses

Credit card interchange income represent fees earned when a credit card issued by the Company is used. Similar to the debit card interchange, Umpqua earns an interchange fee for each transaction made with Umpqua's branded credit cards. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders’ credit card. Certain expenses and rebates directly related to the credit card interchange contract are recorded net to the interchange income. For the three and six months ended June 30, 2018, credit card and interchange income included in other income was $1.8 million and $3.5 million, respectively.

Gain/loss on other real estate owned, net

Umpqua records a gain or loss from the sale of other real estate owned when control of the property transfers to the buyer, which generally occurs at the time of an executed deed of trust. When Umpqua finances the sale of other real estate owned to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the other real estate owned asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on sale, Umpqua adjusts the transaction price and related gain or loss on sale if a significant financing component is present.

Executive Overview 

Significant items for the three and six months ended June 30, 2018 were as follows: 

Financial Performance

• Net earnings available to common shareholders per diluted common share were $0.30 and $0.66 for the three and six months ended June 30, 2018, respectively, compared to $0.26 and $0.47 for the three and six months ended June 30, 2017, respectively.  

• Net interest margin, on a tax equivalent basis, was 3.89% and 3.96% for the three and six months ended June 30, 2018, respectively, as compared to 3.94% and 3.91% for the three and six months ended June 30, 2017, respectively.  The decrease in net interest margin for the three months ended June 30, 2018, compared to the same period in the prior year, was due to an increase in the cost of interest-bearing liabilities and a lower yield on taxable securities, offset by higher average yields on the loan and lease portfolio. The increase in net interest margin for the six months ended June 30, 2018, was primarily driven by higher average yields on the loan and lease portfolio, offset by an increase in the cost of interest-bearing liabilities and a lower yield on taxable securities. The increase in the cost of interest-bearing liabilities was attributable to an increase in average rates paid on interest-bearing deposits, as well as a higher percentage mix of time deposits, relative to prior periods.

• Residential mortgage banking revenue was $33.2 million and $71.6 million for the three and six months ended June 30, 2018, respectively, as compared to $33.9 million and $60.7 million for the three and six months ended June 30, 2017, respectively.  The decrease for the three month period was primarily driven by a decline in mortgage originations, along with a lower gain on sale margin which decreased to 3.35% for the three months ended June 30, 2018, compared to 3.53% in the same period of the prior year. This decrease was partially offset by a lower loss on the fair value of the MSR asset, which decreased to $5.4 million for the three months ended June 30, 2018, as compared to a loss of $8.3 million, for the three months ended June 30, 2017. The increase in residential mortgage banking income for the six month period was primarily driven by a lower loss on the fair value of the MSR asset, which decreased to $324,000, compared to a loss of $16.0 million for the six months ended June 30, 2017. This was offset by a decrease in the gain on sale margin to 3.34% for the six months ended June 30, 2018, compared to 3.41% in the same period of the prior year.

• Total gross loans and leases were $19.6 billion as of June 30, 2018, an increase of $620.3 million, as compared to December 31, 2017.  The increase reflects balanced growth across the Company's commercial term, leasing, multifamily, and residential mortgage loan portfolios, partially offset by a decline in consumer loans attributable to the continued wind down of our indirect auto loan business.

• Total deposits were $20.7 billion as of June 30, 2018, an increase of $796.2 million, compared to December 31, 2017.  This increase was primarily attributable to growth in time and non-interest bearing demand deposits, partially offset by lower money market balances.

• Total consolidated assets were $26.5 billion as of June 30, 2018, compared to $25.7 billion at December 31, 2017.  

Credit Quality

• Non-performing assets decreased to $90.0 million, or 0.34% of total assets, as of June 30, 2018, as compared to $94.1 million, or 0.37% of total assets, as of December 31, 2017.  Non-performing loans were $77.9 million, or 0.40% of total loans, as of June 30, 2018, as compared to $82.3 million, or 0.43% of total loans, as of December 31, 2017.

• The provision for loan and lease losses was $13.3 million and $27.0 million for the three and six months ended June 30, 2018, as compared to the $10.7 million and $22.3 million recognized for the three and six months ended June 30, 2017. The increase for the three and six months ended June 30, 2018, compared to the same periods of the prior year, was primarily attributable to strong growth in the loan and lease portfolio, along with higher net charge-offs. For the three and six months ended June 30, 2018, net charge-offs were $10.7 million and $23.0 million, respectively, or 0.22% and 0.24%, respectively, of average loans and leases (annualized), as compared to $10.1 million and $19.4 million, respectively, or 0.23% and 0.22%, respectively of average loans and leases (annualized), for the three and six months ended June 30, 2017.

Capital and Growth Initiatives

• The Company's total risk based capital was 13.5% and its Tier 1 common to risk weighted assets ratio was 10.7% as of June 30, 2018. As of December 31, 2017, the Company's total risk based capital ratio was 14.1% and its Tier 1 common to risk weighted assets ratio was 11.1%.

• Cash dividends declared in the second quarter of 2018 were $0.20 per common share, an increase of 25% from the comparable period of the prior year's cash dividend of $0.16 per common share.

• For the three months ended June 30, 2018, the Company repurchased 327,000 shares of common stock for $8.0 million.

• In late 2017, the Company launched "Umpqua Next-Gen," an initiative designed to modernize and evolve the Bank focusing on operational excellence, balanced growth and human-digital programs in 2018. As part of this initiative, the Company evaluated every part of how we operate and evolve to deliver a highly differentiated and compelling banking experience. During the six months ended June 30, 2018, Umpqua consolidated 31 stores and completed an organizational simplification and design exercise to streamline and align functions and bring associates closer to our customers. As previously announced, a portion of the savings generated will be re-invested into technology, data and analytics, including new customer-focused technologies, associate training, a re-designed corporate website, digital marketing efforts, and new online account origination capabilities.

Summary of Critical Accounting Policies 

Our significant accounting policies are described in Note 1 to the Consolidated Financial Statementsfor the year ended December 31, 2017 included in the Form 10-K filed with the SEC on February 23, 2018. Not all of these significant accounting policies require management to make difficult, subjective or complex judgments or estimates. Management believes that the following policies would be considered critical under the SEC's definition. 

Allowance for Loan and Lease Losses and Reserve for Unfunded Commitments 

The Bank performs regular credit reviews of the loan and lease portfolio to determine the credit quality and adherence to underwriting standards. When loans and leases are originated, they are assigned a risk rating that is reassessed periodically during the term of the loan through the credit review process.  The Bank's risk rating methodology assigns risk ratings ranging from 1 to 10, where a higher rating represents higher risk. The 10 risk rating categories are a primary factor in determining an appropriate amount for the allowance for loan and lease losses. The Bank has a management Allowance for Loan and Lease Losses ("ALLL") Committee, which is responsible for, among other things, regularly reviewing the ALLL methodology, including loss factors, and ensuring that it is designed and applied in accordance with generally accepted accounting principles. The ALLL Committee reviews and approves loans and leases recommended for impaired status.  The ALLL Committee also approves removing loans and leases from impaired status.  The Bank's Audit and Compliance Committee provides board oversight of the ALLL process and reviews and approves the ALLL methodology on a quarterly basis. 

Each risk rating is assessed an inherent credit loss factor that determines the amount of the allowance for loan and lease losses provided for that group of loans and leases with similar risk rating. Credit loss factors may vary by region if management believes there may ultimately be different credit loss rates experienced in each region.  

Regular credit reviews of the portfolio also identify loans that are considered potentially impaired. Potentially impaired loans are referred to the ALLL Committee which reviews and approves the ultimate designation of loans as impaired. A loan is considered impaired when based on current information and events, we determine that we will probably not be able to collect all amounts due according to the loan contract, including scheduled interest payments. When we identify a loan as impaired, we measure the impairment using discounted cash flows, except when the sole remaining source of repayment for the loan is the liquidation of the collateral. In these cases, we use the current fair value of the collateral, less selling costs, instead of discounted cash flows. If we determine that the value of the impaired loan is less than the recorded investment in the loan, we either recognize an impairment reserve as a specific component to be provided for in the allowance for loan and lease losses or charge-off the impaired balance on collateral dependent loans if it is determined that such amount represents a confirmed loss.  The combination of the risk rating-based allowance component and the impairment reserve allowance component lead to an allocated allowance for loan and lease losses.  

The Bank may also maintain an unallocated allowance amount to provide for other credit losses inherent in a loan and lease portfolio that may not have been contemplated in the credit loss factors. This unallocated amount generally comprises less than 5% of the allowance, but may be maintained at higher levels during times of economic conditions characterized by falling real estate values. The unallocated amount is reviewed periodically based on trends in credit losses, the results of credit reviews and overall economic trends. As of June 30, 2018, there was no unallocated allowance amount.

The RUC is established to absorb inherent losses associated with our commitment to lend funds, such as with a letter or line of credit. The adequacy of the ALLL and RUC are monitored on a regular basis and are based on management's evaluation of numerous factors. These factors include the quality of the current loan portfolio; the trend in the loan portfolio's risk ratings; current economic conditions; loan concentrations; loan growth rates; past-due and non-performing trends; evaluation of specific loss estimates for all significant problem loans; historical charge-off and recovery experience; and other pertinent information.  

Management believes that the ALLL was adequate as of June 30, 2018. There is, however, no assurance that future loan losses will not exceed the levels provided for in the ALLL and could possibly result in additional charges to the provision for loan and lease losses. In addition, bank regulatory authorities, as part of their periodic examination of the Bank, may require additional charges to the provision for loan and lease losses in future periods if warranted as a result of their review. A substantial percentage of our loan portfolio is secured by real estate, as a result a significant decline in real estate market values may require an increase in the allowance for loan and lease losses.  

53

Acquired Loans

Acquired loans and leases are recorded at their fair value at the acquisition date. For purchased non-impaired loans, the difference between the fair value and unpaid principal balance of the loan at the acquisition date is amortized or accreted to interest income using the effective interest method over the remaining contractual period to maturity.

The acquired loans that are purchased impaired loans are aggregated into pools based on individually evaluated common risk characteristics and aggregate expected cash flows were estimated for each pool. A pool is accounted for as a single asset with a single interest rate, cumulative loss rate and cash flow expectation. The cash flows expected to be received over the life of the pool were estimated by management. These cash flows were input into an accounting loan system which calculates the carrying values of the pools and underlying loans, book yields, effective interest income and impairment, if any, based on actual and projected events. Default rates, loss severity, and prepayment speeds assumptions are periodically reassessed and updated within the accounting model to update our expectation of future cash flows. The excess of the cash flows expected to be collected over a pool's carrying value is considered to be the accretable yield and is recognized as interest income over the estimated life of the loan or pool using the effective yield method. The accretable yield may change due to changes in the timing and amounts of expected cash flows. Changes in the accretable yield are disclosed quarterly.

Residential Mortgage Servicing Rights ("MSR") 

The Company determines its classes of servicing assets based on the asset type being serviced along with the methods used to manage the risk inherent in the servicing assets, which includes the market inputs used to value the servicing assets. The Company measures its residential mortgage servicing assets at fair value and reports changes in fair value through earnings.  Fair value adjustments encompass market-driven valuation changes and the runoff in value that occurs from the passage of time, which are separately reported. Under the fair value method, the MSR is carried in the balance sheet at fair value and the changes in fair value are reported in earnings under the caption residential mortgage banking revenue in the period in which the change occurs. 

Retained mortgage servicing rights are measured at fair value as of the date of the related loan sale. We use quoted market prices when available. Subsequent fair value measurements are determined using a discounted cash flow model. In order to determine the fair value of the MSR, the present value of expected net future cash flows is estimated. Assumptions used include market discount rates, anticipated prepayment speeds, delinquency and foreclosure rates, and ancillary fee income net of servicing costs. This model is periodically validated by an independent model validation group. The model assumptions and the MSR fair value estimates are also compared to observable trades of similar portfolios as well as to MSR broker valuations and industry surveys, as available. 

Valuation of Goodwill and Intangible Assets 

Goodwill and other intangible assets with indefinite lives are not amortized but instead are periodically tested for impairment. Management performs an impairment analysis for the intangible assets with indefinite lives on an annual basis as of December 31.  Additionally, goodwill and other intangible assets with indefinite lives are evaluated on an interim basis when events or circumstances indicate impairment potentially exists.  The impairment analysis requires management to make subjective judgments. Events and factors that may significantly affect the estimates include, among others, competitive forces, customer behaviors and attrition, changes in revenue growth trends, cost structures, technology, changes in discount rates and specific industry and market conditions. There can be no assurance that changes in circumstances, estimates or assumptions may result in additional impairment of all, or some portion of, goodwill or other intangible assets. 

The Company performed its annual goodwill impairment analysis as of December 31, 2017. The Company assessed qualitative factors to determine whether the existence of events and circumstances indicated that it is more likely than not that the indefinite-lived intangible asset is impaired, and determined no factors indicated an impairment.

Stock-based Compensation 

We recognize expense in the income statement for the grant-date fair value of restricted shares and stock options as equity-based forms of compensation issued to employees over the employees' requisite service period (generally the vesting period). The requisite service period may be subject to performance conditions. The fair value of the restricted shares is based on the Company's share price on the grant date. Management assumptions utilized at the time of grant impact the fair value of the option calculated under the pricing model, and ultimately, the expense that will be recognized over the expected service period related to each option.

54

Fair Value 

A hierarchical disclosure framework associated with the level of pricing observability is utilized in measuring financial instruments at fair value. The degree of judgment utilized in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Financial instruments with readily available active quoted prices or for which fair value can be measured from actively quoted prices generally will have a higher degree of pricing observability and a lesser degree of judgment utilized in measuring fair value. Conversely, financial instruments rarely traded or not quoted will generally have little or no pricing observability and a higher degree of judgment utilized in measuring fair value. Pricing observability is impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established and the characteristics specific to the transaction.

Results of Operations

Overview

For the three and six months ended June 30, 2018, net earnings available to common shareholders were $66.0 million, or $0.30 per diluted common share and $145.0 million, or $0.66 per diluted common share, respectively, as compared to net earnings available to common shareholders of $57.2 million, or $0.26 per diluted common share, and $103.3 million, or $0.47 per diluted common share, for the three and six months ended June 30, 2017, respectively. The increase in net earnings for the three months ended June 30, 2018 compared to the same period of the prior year was attributable to an increase in net interest income and lower income tax expense, offset by an increase in non-interest expense. The increase in net interest income was driven primarily by higher average yields on interest-earning assets, specifically within the loan and lease portfolio, offset by a higher cost of funds. The decrease in the provision for income taxes was due to the Tax Cuts and Jobs Act passed in December 2017, resulting in an effective tax rate of 24.7% for the three months ended June 30, 2018, as compared to an effective tax rate of 35.8% for the three months ended June 30, 2017. The increase in non-interest expense was driven by severance and other charges related to the organization simplification and design and procurement phases of Umpqua Next-Gen.

The increase in net earnings for the six months ended June 30, 2018 compared to the same period of the prior year was attributable to an increase in net interest income, non-interest income and lower income tax expense, offset by an increase in non-interest expense. The increase in net interest income was driven primarily by higher average yields on interest-earning assets, specifically within the loan and lease portfolio, offset by a higher cost of funds. The increase in non-interest income was driven primarily by higher residential mortgage banking revenues, as well as an increase in swap revenues of $4.0 million as compared to the six months ended June 30, 2017. In addition, there were no losses related to junior subordinated debentures carried at fair value included in earnings as the fair value adjustment for the instrument-specific credit risk was included in other comprehensive loss in 2018. The decrease in the provision for income taxes was due to the Tax Cuts and Jobs Act passed in December 2017, resulting in an effective tax rate of 24.3% for the six months ended June 30, 2018, as compared to an effective tax rate of 36.2% for the six months ended June 30, 2017. The increase in non-interest expense was driven by severance and other charges related to the organization simplification and design and procurement phases of Umpqua Next-Gen, as well as an increase in exit and disposal costs related to store consolidations during the period.

The following table presents the return on average assets, average common shareholders' equity and average tangible common shareholders' equity for the three and six months ended June 30, 2018 and 2017. For each of the periods presented, the table includes the calculated ratios based on reported net earnings available to common shareholders. Our return on average common shareholders' equity is negatively impacted as the result of capital required to support goodwill. To the extent this performance metric is used to compare our performance with other financial institutions that do not have merger and acquisition-related intangible assets, we believe it is beneficial to also consider the return on average tangible common shareholders' equity. The return on average tangible common shareholders' equity is calculated by dividing net earnings available to common shareholders by average shareholders' common equity less average goodwill and intangible assets, net (excluding MSRs). The return on average tangible common shareholders' equity is considered a non-GAAP financial measure and should be viewed in conjunction with the return on average common shareholders' equity.

Average tangible common shareholders' equity	$	2,173,296		$	2,093,072		$	2,165,654		$	2,082,086

Additionally, management believes tangible common equity and the tangible common equity ratio are meaningful measures of capital adequacy. Umpqua believes the exclusion of certain intangible assets in the computation of tangible common equity and tangible common equity ratio provides a meaningful base for period-to-period and company-to-company comparisons, which management believes will assist investors in analyzing the operating results and capital of the Company.  Tangible common equity is calculated as total shareholders' equity less preferred stock and less goodwill and other intangible assets, net (excluding MSRs).  In addition, tangible assets are total assets less goodwill and other intangible assets, net (excluding MSRs).  The tangible common equity ratio is calculated as tangible common shareholders' equity divided by tangible assets. The tangible common equity and tangible common equity ratio is considered a non-GAAP financial measure and should be viewed in conjunction with the total shareholders' equity and the total shareholders' equity ratio. 

The following table provides a reconciliation of ending shareholders' equity (GAAP) to ending tangible common equity (non-GAAP), and ending assets (GAAP) to ending tangible assets (non-GAAP) as of June 30, 2018 and December 31, 2017: 

Reconciliations of Total Shareholders' Equity to Tangible Common Shareholders' Equity and Total Assets to Tangible Assets

Non-GAAP financial measures have inherent limitations, are not required to be uniformly applied, and are not reviewed or audited.  Although we believe these non-GAAP financial measures are frequently used by stakeholders in the evaluation of a company, they have limitations as analytical tools, and should not be considered in isolation or as a substitute for analyses of results as reported under GAAP.

Net Interest Income 

Net interest income is the largest source of our income. Net interest income for the three and six months ended June 30, 2018 was $224.9 million and $449.9 million, respectively, an increase of $12.2 million and $30.4 million, respectively, compared to the same periods in 2017. The increase in net interest income for the three and six months ended June 30, 2018 as compared to the same periods in 2017, reflects higher average loans and leases, driven by strong growth during the periods, and higher average loan and lease yields. The increase was partially offset by increased volumes of interest-bearing liabilities and an increase in the average cost of funds due to rising market rates.

The net interest margin (net interest income as a percentage of average interest-earning assets) on a fully tax equivalent basis was 3.89% and 3.96% for the three and six months ended June 30, 2018, a decrease of 5 basis points and an increase of 5 basis points, respectively, as compared to the same periods in 2017. The decrease in net interest margin for the three months ended June 30, 2018, primarily resulted from an increase in the cost of interest-bearing liabilities and a lower yield on taxable securities, offset by higher average yields on the loan and lease portfolio. The increase in net interest margin for the six months ended June 30, 2018, was primarily the result of higher average yields on the loan and lease portfolio, offset by an increase in the cost of interest-bearing liabilities and a lower yield on taxable securities. The yield on loans and leases increased by 21 basis points and 18 basis points, respectively, for the three and six months ended June 30, 2018, as compared to the same periods in 2017.

Our net interest income is affected by changes in the amount and mix of interest-earning assets and interest-bearing liabilities, as well as changes in the yields earned on interest-earning assets and rates paid on deposits and borrowed funds.

Provision for Loan and Lease Losses 

The provision for loan and lease losses was $13.3 million and $27.0 million, respectively, for the three and six months ended June 30, 2018, as compared to $10.7 million and $22.3 million, respectively, for the same periods in 2017.  As an annualized percentage of average outstanding loans and leases, the provision for loan and lease losses recorded for the three and six months ended June 30, 2018 was 0.28%, as compared to 0.24% and 0.25%, respectively, in the same periods in 2017. 

The increase in the provision for the three and six months ended June 30, 2018 as compared to the same prior year periods is primarily attributable to growth in the loan and lease portfolio, as well as an increase in net charge-offs. Net charge-offs on loans were $10.7 million and $23.0 million for the three and six months ended June 30, 2018, respectively, or 0.22% and 0.24%, respectively, of average loans and leases (annualized), as compared to net charge-offs of $10.1 million and $19.4 million, respectively, or 0.23% and 0.22%, respectively of average loans and leases (annualized), for the three and six months ended June 30, 2017. The majority of net charge-offs relate to losses realized in the lease portfolio, which is included in the commercial loan portfolio.

The Company recognizes the charge-off of impairment reserves on impaired loans in the period they arise for collateral-dependent loans.  Therefore, the non-accrual loans of $43.4 million as of June 30, 2018 have been written-down to their estimated fair value, less estimated costs to sell, and are expected to be resolved with no additional material loss, absent further decline in market prices.

Non-Interest Income 

Non-interest income for the three months ended June 30, 2018 was $71.7 million, an increase of $532,000, or 1%, as compared to the same period in 2017. Non-interest income for the six months ended June 30, 2018 was $150.2 million, an increase of $18.9 million, or 14% as compared to the same period in 2017. The following table presents the key components of non-interest income for the three and six months ended June 30, 2018 and 2017:

Residential mortgage banking revenue for the three and six months ended June 30, 2018 as compared to the same periods of 2017 decreased by $731,000 and increased by $10.9 million, respectively. The decrease for the three month period was primarily driven by a decline in mortgage originations, along with a lower gain on sale margin which decreased to 3.35% for the three months ended June 30, 2018, compared to 3.53% in the same period of the prior year. This decrease was partially offset by a lower loss on fair value of the MSR asset of $5.4 million for the three months ended June 30, 2018, as compared to the loss on fair value of $8.3 million for the three months ended June 30, 2017. The increase for the six month period was primarily driven by a lower loss on fair value of the MSR asset of $324,000 relative to the loss on fair value of $16.0 million for the six months ended June 30, 2017. This was offset by a decrease in the gain on sale margin to 3.34% for the six months ended June 30, 2018, compared to 3.41% in the same period of the prior year.

For the three and six months ended June 30, 2018, the unrealized holding losses on equity securities of $1.4 million were reported in earnings rather than in other comprehensive losses, net of tax, due to a change in accounting principle that requires equity securities to be recorded at fair value with changes in fair value reported in net income.

The gain on loan sales for the three and six months ended June 30, 2018decreased by $2.0 million and $2.5 million due to the mix and volume of loans sold during the periods.

For the three and six months ended June 30, 2018, the losses on junior subordinated debentures carried at fair value of $1.5 million and $3.2 million, respectively, were recorded net of tax as other comprehensive losses of $1.1 million and $2.4 million, respectively, rather than reported in earnings as in prior periods due to a change in accounting principle for liabilities elected to be recorded at fair value.

Other income for the three and six months ended June 30, 2018 compared to the same periods in the prior year increased by $2.8 million and $8.2 million, respectively. The increase was primarily related to the debt capital market swap derivatives revenues which increased by $1.2 million and $4.0 million, respectively, during the periods. Also included in other income for the six months ended June 30, 2018 is a $1.0 million gain on the early redemption by the Company of two junior subordinated debentures, and a $1.2 million gain on residual value of leased assets, contributing to the increase in other income.

Non-Interest Expense 

Non-interest expense for the three and six months ended June 30, 2018 was $195.6 million and $381.7 million, an increase of $11.6 million and $15.0 million, respectively, or 6% and 4% as compared to the same periods in 2017. The following table presents the key elements of non-interest expense for the three and six months ended June 30, 2018 and 2017:

Salaries and employee benefits costs increased by $4.8 million and $4.9 million for the three and six months ended June 30, 2018, respectively, as compared to the same periods in the prior year, primarily related to employee severance due to organizational simplification efforts during 2018. Retirement benefits also increased due to the profit sharing contribution accruals in 2018.

Services expense increased by $5.2 million and $9.0 million for the three and six months ended June 30, 2018, respectively, as compared to the same periods in the prior year, primarily related to consulting fees in 2018 to help identify and implement organizational simplification and efficiencies, including procurement, occupancy optimization, and providing a more efficient customer experience.

The merger related expenses of $1.6 million and $2.7 million for the three and six months ended June 30, 2017 relate to the merger with Sterling and were the result of costs associated with the final work on a non-customer facing system conversion. There were no merger related expenses in 2018.

Other non-interest expense increased by $1.8 million and $2.9 million for the three and six months ended June 30, 2018, respectively, as compared to the same periods in the prior year. The increase is primarily due to exit or disposal costs which increased by $1.8 million and $3.9 million during the three and six months ended June 30, 2018, respectively, related to 31 store closures during the six months ended June 30, 2018. This was offset by a decrease in litigation settlement losses of $872,000, for the six months ended June 30, 2018, as compared to the same period in 2017.

Income Taxes 

The Company's consolidated effective tax rate as a percentage of pre-tax income for the three and six months ended June 30, 2018 was 24.7% and 24.3%, respectively, as compared to 35.8% and 36.2% for the three and six months ended June 30, 2017, respectively. The effective tax rates for the current periods differed from the federal statutory rate of 21% and the apportioned state rate of 6% (net of the federal tax benefit) principally because of the relative amount of income earned in each state jurisdiction, non-taxable income arising from bank-owned life insurance, income on tax-exempt investment securities, stock-based compensation, non-deductible FDIC premiums and tax credits arising from low-income housing investments.  

FINANCIAL CONDITION 

Investment Securities 

Equity and other securities were $64.3 million at June 30, 2018, up from $12.3 million at December 31, 2017. The increasereflects the prospective change in classification of equity securities that were previously classified as available for sale.

Investment securities available for sale were $2.9 billion as of June 30, 2018, compared to $3.1 billion at December 31, 2017.  The decrease was due to sales and paydowns of $227.9 million, a decrease in fair value of investment securities available for sale of $46.2 million and the reclassification of equity securities previously classified as available for sale, offset by purchases of $134.1 million of investment securities.

Investment securities held to maturity were $3.6 million as of June 30, 2018, as compared to $3.8 million at December 31, 2017. The change primarily related to paydowns and maturities of investment securities held to maturity of $278,000.

The following tables present the available for sale and held to maturity investment securities portfolio by major type as of June 30, 2018 and December 31, 2017:

We review investment securities on an ongoing basis for the presence of other-than-temporary impairment ("OTTI") or permanent impairment, taking into consideration current market conditions, fair value in relationship to cost, extent and nature of the change in fair value, issuer rating changes and trends, whether we intend to sell a security or if it is likely that we will be required to sell the security before recovery of our amortized cost basis of the investment, which may be maturity, and other factors.

Gross unrealized losses in the available for sale investment portfolio were $83.3 million at June 30, 2018.  This consisted primarily of unrealized losses on residential mortgage-backed securities and collateralized mortgage obligations of $79.0 million. The unrealized losses were caused by changes in market interest rates or the widening of market spreads subsequent to the initial purchase of these securities and are not due to the underlying credit of the issuers. In the opinion of management, these securities are considered only temporarily impaired due to changes in market interest rates or the widening of market spreads subsequent to the initial purchase of the securities, and not due to concerns regarding the underlying credit of the issuers or the underlying collateral.

Restricted Equity Securities 

Restricted equity securities were $42.3 million at June 30, 2018 and $43.5 million at December 31, 2017, the majority of which represents the Bank's investment in the FHLB of Des Moines. The decrease is attributable to the redemption of Pacific Coast Banker's Bank stock. FHLB stock is carried at par and does not have a readily determinable fair value. Ownership of FHLB stock is restricted to the FHLB and member institutions, and can only be purchased and redeemed at par. 

Loans and Leases

Loans andLeases, net 

Total loans and leases outstanding at June 30, 2018 were $19.6 billion, an increase of $620.3 million as compared to year-end 2017. The increase is principally attributable to net new loan and lease originations of $687.5 million, partially offset by loans sold of $39.0 million, charge-offs of $30.6 million and transfers to other real estate owned of $1.9 million during the period.

The following table presents the concentration distribution of the loan and lease portfolio, net of deferred fees and costs, as of June 30, 2018 and December 31, 2017.

(1) Excludes government guaranteed GNMA mortgage loans that Umpqua has the right but not the obligation to repurchase that are past due 90 days or more totaling $9.2 million and $12.4 million at June 30, 2018 and December 31, 2017, respectively.

(2) Represents accruing restructured loans performing according to their restructured terms. 

The purchased non-credit impaired loans had remaining discount that is expected to accrete into interest income over the life of the loans of $29.5 million and $36.7 million, as of June 30, 2018 and December 31, 2017, respectively. The purchased credit impaired loan pools had remaining discount of $28.0 million and $33.2 million, as of June 30, 2018 and December 31, 2017, respectively.

Loans acquired with deteriorated credit quality are accounted for as purchased credit impaired pools. Typically, this would include loans that were considered non-performing or restructured as of acquisition date. Accordingly, subsequent to acquisition, loans included in the purchased credit impaired pools are not reported as non-performing loans based upon their individual performance status, so the categories of nonaccrual, impaired and 90 days past due and accruing do not include any purchased credit impaired loans.

Restructured Loans 

At June 30, 2018 and December 31, 2017, impaired loans of $27.2 million and $32.2 million, respectively, were classified as performing restructured loans. The restructurings were granted in response to borrower financial difficulty, and generally provide for a temporary modification of loan repayment terms. In order for a new restructured loan to be considered performing and on accrual status, the loan's collateral coverage generally will be greater than or equal to 100% of the loan balance, the loan must be current on payments, and the borrower must either prefund an interest reserve or demonstrate the ability to make payments from a verified source of cash flow.

A further decline in the economic conditions in our general market areas or other factors could adversely impact individual borrowers or the loan portfolio in general. Accordingly, there can be no assurance that loans will not become 90 days or more past due, become impaired or placed on non-accrual status, restructured or transferred to other real estate owned in the future.

Allowance for Loan and Lease Losses and Reserve for Unfunded Commitments 

The ALLL totaled $144.6 million at June 30, 2018, an increase of $3.9 million from $140.6 million at December 31, 2017. The following table shows the activity in the ALLL for the three and six months ended June 30, 2018 and 2017:

Recoveries as a percentage of charge-offs	27.80		%	27.70		%	24.81		%	27.83		%

The increase in allowance for loan and lease losses as of June 30, 2018 compared to the same period of the prior year was primarily attributable to strong growth in the loan portfolio as well as an increase in net charge-offs. Additional discussion on the change in provision for loan and lease losses is provided under the heading Provision for Loan and LeaseLosses above.

The following table sets forth the allocation of the allowance for loan and lease losses and percent of loans in each category to total loans and leases as of June 30, 2018 and December 31, 2017: 

(dollars in thousands)	June 30, 2018				December 31, 2017
	Amount		% Loans to total loans		Amount		% Loans to total loans
Commercial real estate	$	47,285	50.6	%	$	45,765	51.1	%
Commercial	65,765		23.0	%	63,305		22.4	%
Residential	20,275		23.1	%	19,360		22.5	%
Consumer & other	11,231		3.3	%	12,178		4.0	%
Allowance for loan and lease losses	$	144,556			$	140,608

At June 30, 2018, the recorded investment in loans classified as impaired totaled $46.0 million, with a corresponding valuation allowance (included in the allowance for loan and lease losses) of $821,000.  The valuation allowance on impaired loans represents the impairment reserves on performing current and former restructured loans and nonaccrual loans. At December 31, 2017, the total recorded investment in impaired loans was $59.9 million, with a corresponding valuation allowance (included in the allowance for loan and lease losses) of $535,000.

The following table presents a summary of activity in the RUC:  

Summary of Reserve for Unfunded Commitments Activity 

(in thousands)	Three months ended				Six Months Ended
	June 30, 2018		June 30, 2017		June 30, 2018		June 30, 2017

Net charge to other expense	1		321		167		205
Balance, end of period	$	4,130	$	3,816	$	4,130	$	3,816

We believe that the ALLL and RUC at June 30, 2018 are sufficient to absorb losses inherent in the loan and lease portfolio and credit commitments outstanding as of that date based on the information available. This assessment, based in part on historical levels of net charge-offs, loan and lease growth, and a detailed review of the quality of the loan and lease portfolio, involves uncertainty and judgment. Therefore, the adequacy of the ALLL and RUC cannot be determined with precision and may be subject to change in future periods. In addition, bank regulatory authorities, as part of their periodic examination of the Bank, may require additional charges to the provision for loan and lease losses in future periods if warranted as a result of their review.

Residential Mortgage Servicing Rights

Goodwill and Other Intangibles Assets

At June 30, 2018 and December 31, 2017, we had goodwill of $1.8 billion.  Goodwill is recorded in connection with business combinations and represents the excess of the purchase price over the estimated fair value of the net assets acquired. There were no changes to goodwill during the three and six months ended June 30, 2018.

At June 30, 2018, we had other intangible assets of $27.0 million, as compared to $30.1 million at December 31, 2017.   As part of a business acquisition, the fair value of identifiable intangible assets such as core deposits, which include all deposits except certificates of deposit, are recognized at the acquisition date. Intangible assets with definite useful lives are amortized to their estimated residual values over their respective estimated useful lives, and are also reviewed for impairment. We amortize other intangible assets on an accelerated or straight-line basis over an estimated ten to fifteen year life. The decrease from December 31, 2017 relates to the amortization of the other intangible assets of $3.1 million for the six months endedJune 30, 2018.

Deposits 

Total deposits were $20.7 billion at June 30, 2018, an increase of $796.2 million, as compared to December 31, 2017. The increase is attributable to growth in time deposits in addition to an increase in non-interest bearing demand, partially offset by lower money market balances attributable to planned public and brokered funds run-off.

The following table presents the deposit balances by major category as of June 30, 2018 and December 31, 2017: 

(dollars in thousands)	June 30, 2018				December 31, 2017
	Amount		Percentage		Amount		Percentage
Non-interest bearing demand	$	6,819,325	33	%	$	6,505,628	33	%
Interest bearing demand	2,321,691		11	%	2,384,133		12	%
Money market	6,161,907		30	%	7,037,891		35	%
Savings	1,465,154		7	%	1,446,860		7	%
Time, $100,000 or greater	3,000,638		14	%	1,684,498		8	%
Time, less than $100,000	975,811		5	%	889,290		5	%
Total	$	20,744,526	100	%	$	19,948,300	100	%

The Company's brokered deposits, including Certificate of Deposit Account Registry Service ("CDARS"), totaled $1.5 billion at June 30, 2018 compared to $930.9 million at December 31, 2017.  The growth in brokered time deposits was partially offset by a decline in brokered money market deposits.

Borrowings 

At June 30, 2018, the Bank had outstanding $273.7 million of securities sold under agreements to repurchase and no outstanding federal funds purchased balances. The Bank had outstanding term debt consisting of advances from the FHLB of $801.7 million at June 30, 2018, and are secured by investment securities and loans secured by real estate. The FHLB advances have fixed interest rates ranging from 1.16% to 7.10% and mature in 2018 through 2030.

Junior Subordinated Debentures 

We had junior subordinated debentures with carrying values of $369.5 million and $377.8 million at June 30, 2018 and December 31, 2017, respectively.  The decrease is due to the redemption of the Humboldt Bancorp Statutory Trust I and HB Capital Trust I junior subordinated debentures, which had carrying values of $11.7 million as of December 31, 2017. The decrease is partially offset by the increase in fair value for the junior subordinated debentures elected to be carried at fair value. As of June 30, 2018, substantially all of the junior subordinated debentures had interest rates that are adjustable on a quarterly basis based on a spread over three month LIBOR.  

69

Liquidity and Cash Flow 

The principal objective of our liquidity management program is to maintain the Bank's ability to meet the day-to-day cash flow requirements of our customers who either wish to withdraw funds or to draw upon credit facilities to meet their cash needs. 

We monitor the sources and uses of funds on a daily basis to maintain an acceptable liquidity position. One source of funds includes public deposits. Individual state laws require banks to collateralize public deposits, typically as a percentage of their public deposit balance in excess of FDIC insurance.  Public deposits represented 7% of total deposits at June 30, 2018 and 9% of total deposits at December 31, 2017. The amount of collateral required varies by state and may also vary by institution within each state, depending on the individual state's risk assessment of depository institutions. Changes in the pledging requirements for uninsured public deposits may require pledging additional collateral to secure these deposits, drawing on other sources of funds to finance the purchase of assets that would be available to be pledged to satisfy a pledging requirement, or could lead to the withdrawal of certain public deposits from the Bank. In addition to liquidity from core deposits and the repayments and maturities of loans and investment securities, the Bank can utilize established uncommitted federal funds lines of credit, sell securities under agreements to repurchase, borrow on a secured basis from the FHLB or issue brokered certificates of deposit.  

The Bank had available lines of credit with the FHLB totaling $7.0 billion at June 30, 2018, subject to certain collateral requirements, namely the amount of pledged loans and investment securities. The Bank had available lines of credit with the Federal Reserve totaling $557.1 million, subject to certain collateral requirements, namely the amount of certain pledged loans. The Bank had uncommitted federal funds line of credit agreements with additional financial institutions totaling $450.0 million at June 30, 2018. Availability of these lines is subject to federal funds balances available for loan and continued borrower eligibility. These lines are intended to support short-term liquidity needs, and the agreements may restrict consecutive day usage. 

The Company is a separate entity from the Bank and must provide for its own liquidity. Substantially all of the Company's revenues are obtained from dividends declared and paid by the Bank. There were $107.5 million of dividends paid by the Bank to the Company in the six months ended June 30, 2018.  There are statutory and regulatory provisions that could limit the ability of the Bank to pay dividends to the Company. We believe that such restrictions will not have an adverse impact on the ability of the Company to fund its quarterly cash dividend distributions to common shareholders and meet its ongoing cash obligations, which consist principally of debt service on the outstanding junior subordinated debentures.  

As disclosed in the Condensed ConsolidatedStatements of Cash Flows, net cash provided by operating activities was $49.4 million during the six months ended June 30, 2018, with the difference between cash provided by operating activities and net income largely consisting of originations of loans held for sale of $1.5 billion, offset by proceeds from the sale of loans held for sale of $1.4 billion. This compares to net cash provided by operating activities of $84.5 million during the six months ended June 30, 2017, with the difference between cash provided by operating activities and net income largely consisting of proceeds from the sale of loans held for sale of $1.7 billion, offset by originations of loans held for sale of $1.7 billion.

Net cash of $550.2 million used in investing activities during the six months ended June 30, 2018, consisted principally of net loan originations of $687.5 million, purchases of investment securities available for sale of $134.1 million, and purchases of restricted equity securities of $45.6 million, offset by proceeds from investment securities available for sale of $227.9 million, redemption of restricted equity securities of $46.8 million and proceeds from sale of loans and leases of $41.6 million. This compares to net cash of $1.3 billion used in investing activities during the six months ended June 30, 2017, which consisted principally of net loan originations of $923.4 million, purchases of investment securities available for sale of $725.5 million, and purchases of restricted equity securities of $236.6 million, offset by proceeds from investment securities available for sale of $297.4 million, redemption of restricted equity securities of $236.6 million and proceeds from the sale of loans and leases of $98.6 million.

Net cash of $669.6 million provided by financing activities during the six months ended June 30, 2018 primarily consisted of $796.6 million increase in net deposits and proceeds from term debt borrowings of $50.0 million, offset by $83.7 million of dividends paid on common stock, $50.7 million repayment of term debt, a net decrease in securities sold under agreements to repurchase of $20.6 million, $12.5 million in the repurchase and retirement of common stock, and $10.6 million repayment on junior subordinated debentures. This compares to net cash of $340.8 million provided by financing activities during the six months ended June 30, 2017, which consisted primarily of $439.6 million increase in net deposits and proceeds from term debt borrowings of $100.0 million, offset by $100.0 million repayment of term debt, $70.5 million in dividends paid on common stock and a net decrease in securities sold under agreements to repurchase of $22.8 million.

70

Although we expect the Bank's and the Company's liquidity positions to remain satisfactory during 2018, it is possible that our deposit growth for 2018 may not be maintained at previous levels due to pricing pressure or store consolidations. In addition, in order to generate deposit growth, our pricing may need to be adjusted in a manner that results in increased interest expense on deposits.

Off-balance-Sheet Arrangements 

Information regarding Off-Balance-Sheet Arrangements is included in Note 8 of the Notes to Condensed Consolidated Financial Statements.

Concentrations of Credit Risk 

Information regarding Concentrations of Credit Risk is included in Note 8 of the Notes to Condensed Consolidated Financial Statements.

Capital Resources 

Shareholders' equity at June 30, 2018 was $4.0 billion, an increase of $11.7 million from December 31, 2017. The increase in shareholders' equity during the six months ended June 30, 2018 was principally due to net income for the period, offset by declared common dividends and other comprehensive loss, net of tax.

The Company's dividend policy considers, among other things, earnings, regulatory capital levels, the overall payout ratio and expected asset growth to determine the amount of dividends declared, if any, on a quarterly basis. There is no assurance that future cash dividends on common shares will be declared or increased. The following table presents cash dividends declared and dividend payout ratios (dividends declared per common share divided by basic earnings per common share) for the three and six months ended June 30, 2018 and 2017:   

Cash Dividends and Payout Ratios per Common Share 

	Three months ended						Six Months Ended
	June 30, 2018			June 30, 2017			June 30, 2018			June 30, 2017
Dividend declared per common share	$	0.20		$	0.16		$	0.40		$	0.32
Dividend payout ratio	67		%	62		%	61		%	68		%

As of June 30, 2018, a total of 10.2 million shares are available for repurchase under the Company's current share repurchase plan. During six months ended June 30, 2018, the Company repurchased 327,000 shares under this plan. The Board of Directors approved an extension of the repurchase plan to July 31, 2019. The timing and amount of future repurchases will depend upon the market price for our common stock, securities laws restricting repurchases, asset growth, earnings, and our capital plan.  In addition, our stock plans provide that option and award holders may pay for the exercise price and tax withholdings in part or whole by tendering previously held shares.

Item 3.Quantitative and Qualitative Disclosures about Market Risk 

Our assessment of market risk as of June 30, 2018 indicates there are no material changes in the quantitative and qualitative disclosures from those in our Annual Report on Form 10-K for the year ended December 31, 2017.

72

Item 4.Controls and Procedures 

Our management, including our Chief Executive Officer, Chief Financial Officer and Principal Accounting Officer, has concluded that our disclosure controls and procedures are effective in timely alerting them to information relating to us that is required to be included in our periodic filings with the SEC. The disclosure controls and procedures were last evaluated by management as of June 30, 2018. 

No change in our internal controls occurred during the second quarter of 2018 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

Part II. OTHERINFORMATION 

Item 1.Legal Proceedings 

Due to the nature of our business, we are involved in legal proceedings that arise in the ordinary course of our business. While the outcome of these matters is currently not determinable, we do not expect that the ultimate costs to resolve these matters will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Item 1A.   Risk Factors 

In addition to the other information set forth in this report, you should carefully consider the factors discussed under "Part I--Item 1A--Risk Factors" in our Form 10-K for the year ended December 31, 2017.   These factors could materially and adversely affect our business, financial condition, liquidity, results of operations and capital position, and could cause our actual results to differ materially from our historical results or the results contemplated by the forward-looking statements contained in this report. There have been no material changes from the risk factors described in our Form 10-K.

Item 2.Unregistered Sales of Equity Securities and Use of Proceeds

(a)Not applicable  

(b)Not applicable 

(c)The following table provides information about repurchases of common stock by the Company during the quarter ended June 30, 2018: 

Period	Total number of Common Shares Purchased (1)	Average Price Paid per Common Share		Total Number of Shares Purchased as Part of Publicly Announced Plan (2)	Maximum Number of Remaining Shares that May be Purchased at Period End under the Plan

Total for quarter	334,854	$	24.38	—

(1) Common shares repurchased by the Company during the quarter consist of cancellation of 1,551 shares to be issued upon vesting of restricted stock awards and 6,303 shares to be issued upon vesting of restricted stock units to pay withholdingtaxes. During the three months ended June 30, 2018, 327,000 shares were repurchased pursuant to the Company's publicly announced corporate stock repurchase plan described in (2) below.

(2) The Company's share repurchase plan, which was first approved by its Board of Directors and announced in August 2003, was amended on September 29, 2011 to increase the number of common shares available for repurchase under the plan to 15 million shares. The repurchase program has been extended multiple times by the board with the current expiration date of July 31, 2019. As of June 30, 2018, a total of 10.2 million shares remained available for repurchase. The timing and amount of future repurchases will depend upon the market price for our common stock, laws and regulations restricting repurchases, asset growth, earnings, and our capital plan.

Item 3.Defaults upon Senior Securities 

Not applicable

Item 4.Mine Safety Disclosures 

Not applicable

Item 5.Other Information 

As disclosed in Note 1 to the Condensed Consolidated Financial Statements, a correction of prior period balances has been made in the current 10-Q to reflect the correction of the calculation and corresponding recognition of the accretion of the purchase accounting discount on the loans acquired from Sterling Financial Corporation (ASC 310-20 loans). Management believes that the effect of this restatement is not material to our previously issued consolidated financial statements. We have therefore restated in the accompanying financial statements the previously presented consolidated balance sheet and statement of changes in shareholders equity as of December 31, 2017. We will prospectively correct the prior periods in our future filings of the 2018 Quarterly Report on Form 10-Q as of September 30, 2018, the 2018 Annual Report on Form 10-K and the 2019 Quarterly Report on Form 10-Q as of March 31, 2019. The following is a summary of the adjustment for each period to reflect the impact of the correction on prior periods, noting that only required comparative periods have been revised in this 10-Q.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies 

The accounting and financial reporting policies of Umpqua Holdings Corporation conform to accounting principles generally accepted in the United States of America. The accompanying interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries.  All inter-company balances and transactions have been eliminated. The condensed consolidated financial statements have not been audited. A more detailed description of our accounting policies is included in the 2017 Annual Report filed on Form 10-K. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the 2017 Annual Report filed on Form 10-K. All references in this report to "Umpqua," "we," "our," "us," the "Company" or similar references mean Umpqua Holdings Corporation, and include our consolidated subsidiaries where the context so requires. References to "Bank" refer to our subsidiary Umpqua Bank, an Oregon state-chartered commercial bank, and references to "Umpqua Investments" refer to our subsidiary Umpqua Investments, Inc., a registered broker-dealer and investment adviser. The Bank also has a wholly-owned subsidiary, Financial Pacific Leasing Inc., a commercial equipment leasing company. Pivotus Ventures, Inc., a wholly-owned subsidiary of Umpqua Holdings Corporation, focuses on advancing bank innovation by developing new bank platforms that could have a significant impact on the experience and economics of banking.

In preparing these condensed consolidated financial statements, the Company has evaluated events and transactions subsequent to June 30, 2018 for potential recognition or disclosure. In management's opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments include normal and recurring accruals considered necessary for a fair and accurate presentation. The results for interim periods are not necessarily indicative of results for the full year or any other interim period.  

Out of Period Correction

Subsequent to the issuance of the Company's March 31, 2018 condensed consolidated financial statements, the Company's management determined that a prospective interest method versus retrospective interest method was incorrectly used to recognize income on the portfolio of residential mortgage-backed securities and collateralized mortgage obligations which has a fair value of $2.5 billion as of June 30, 2018. These securities are considered structured note securities as defined by ASC 320-10-35. Income on these securities should be recognized using the retrospective interest method. The Company has historically used the prospective method of income recognition for these securities. For other types of securities, there are other methods of income recognition allowed by the guidance. We concluded that the difference between these two methodologies is immaterial. The Company has changed to the retrospective interest method as of June 30, 2018. To reflect this change, the cumulative difference between these two methods of $7.2 million has been recognized as an out of period adjustment in the current period, resulting in a decrease in interest income on taxable investment securities and a corresponding decrease in the unrealized loss on taxable investment securities. We have concluded that this error has an immaterial impact to the results for 2018, as well as prior periods. The Company has recorded the adjustment in the quarter ended June 30, 2018, no other periods have been updated to reflect this adjustment.

Correction of Prior Period Balances

Subsequent to the issuance of the Company's March 31, 2018 condensed consolidated financial statements, the Company's management determined that the calculation and corresponding recognition of the accretion of the purchase accounting discount on the loans acquired from Sterling Financial Corporation (ASC 310-20 loans) that were not impaired was calculated in a manner that was considered to be inconsistent with accounting principals generally accepted in the United States of America as indicated in ASC 310-20. As a result, the financial statements have been restated to reflect the correction of the difference in accretion/amortization related to the loans acquired. Management believes that the effect of this restatement is not material to our previously issued consolidated financial statements.

As the error began in 2014, a prior period adjustment has been recorded to reflect the difference in loans and leases, as well as retained earnings in the opening period that is first reported in this 10-Q. As a result, the condensed consolidated statements of income have been revised to reflect these changes to the applicable line items as follows.

Total liabilities and shareholders' equity	$	25,741,439	$	(60,992	)	$	25,680,447

The condensed consolidated statement of changes in shareholders' equity has a prior period adjustment of $41.7 million to reflect the correction of the accretion amounts since the acquisition date in April 2014 to December 31, 2016. In addition, the following amounts have been revised in the condensed consolidated statement of changes in shareholders' equity.

(in thousands)	As Originally Reported		Adjustment			As Revised
Net income for the year ended December 31, 2017	$	246,019	$	(3,706	)	$	242,313
Retained earnings as of December 31, 2017	$	522,520	$	(45,419	)	$	477,101
Total equity as of December 31, 2017	$	4,014,786	$	(45,419	)	$	3,969,367

The condensed consolidated statement of comprehensive income has been updated to reflect the change in net income for the three and six months ended June 30, 2017. Comprehensive income increased by $407,000 for the three months ended June 30, 2017 to $66.0 million and by $440,000 for the six months ended June 30, 2017 to $114.5 million. The condensed consolidated statement of cash flows has also been updated to reflect these changes, resulting in an increase in cash flows from operating activities for June 30, 2017 of $717,000 to reflect the increase in net income and the change in other liabilities (deferred tax liability) and a corresponding decrease in the cash flows from investing activities of $717,000 for June 30, 2017 as part of the net change in loans and leases.

Periods not presented herein will be revised, as applicable, as they are included in future filings.

Application of new accounting guidance

As of January 1, 2018, Umpqua adopted the Financial Accounting Standard Board's ("FASB") Accounting Standard Update ("ASU") No. 2014-09, Revenue from Contracts with Customers and all subsequent amendments to the ASU (collectively "ASC 606"), which (i) creates a single framework for recognizing revenue from contracts with customers that are within its scope and (ii) revises when it is appropriate to recognize a gain or loss from the transfer of nonfinancial assets such as other real estate owned. The majority of Umpqua's revenues come from interest income and other sources, including loans, leases, securities, and derivatives, that are outside the scope of ASC 606. Umpqua's revenues that are within the scope of ASC 606 are presented within Non-Interest Income and are recognized as revenue as the Company satisfies its obligation to the customer. Revenues within the scope of ASC 606 include service charges on deposits, brokerage revenue, interchange income, and the sale of other real estate owned. Refer to Note 15 - Revenue from Contracts with Customers for further discussion of Umpqua's accounting policies for revenue sources within the scope of ASC 606.

Umpqua adopted ASC 606 using the modified retrospective method applied on all contracts not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606 while prior period amounts continue to be reported in accordance with legacy generally accepted accounting principles ("GAAP"). The adoption of ASC 606 did not result in a material change to the accounting for any of the in-scope revenue streams; as such, no cumulative effect adjustment was recorded.

As of January 1, 2018, Umpqua applied FASB ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The new guidance relates to the recognition and measurement of financial instruments. This ASU requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Upon adoption, certain equity securities were reclassified from available for sale to the equity securities classification on the balance sheet. The ASU was applied prospectively. The amendment also requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. This ASU also eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. The disclosures in the fair value footnote have been updated accordingly.

The amendment also requires a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument specific credit risk (also referred to as "own credit") when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. The Company's junior subordinated debentures are variable-rate instruments based on LIBOR, with the majority resetting quarterly. Applying the updated guidance, the FASB noted that the entire risk in excess of the risk free or benchmark rate could be considered instrument-specific credit risk. The Company has determined that all changes in fair value of the junior subordinated debentures are due to changes in value other than in the benchmark rate, and accordingly are instrument-specific credit risk. As such, the Company calculated the change in the discounted cash flows based on updated market credit spreads since the election of the fair value option for each junior subordinated debenture measured at fair value to be a net gain of $13.0 million. The gain was recorded, net of the tax effect, as a cumulative effect adjustment between retained earnings and accumulated other comprehensive income (loss), resulting in an adjustment of $9.7 million upon adoption.

For 2018, the change in fair value is attributable to the change in the instrument specific credit risk of the junior subordinated debentures, as determined by the application of ASU 2016-01. Accordingly, the loss on fair value of junior subordinated debentures for the three and six months ended June 30, 2018 of $1.5 million and $3.2 million, respectively, is recorded in other comprehensive income (loss), net of tax, as an other comprehensive loss of $1.1 million and $2.4 million, respectively.

Recent accounting pronouncements 

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) as well as additional ASUs for enhancement, clarification or transition of the new lease standard (collectively "ASC 842"). ASC 842 will require lessees, among other things, to recognize lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous authoritative guidance. This update also introduces new disclosure requirements for leasing arrangements. ASC 842 is effective for financial statements issued for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The Company has established a project team for the implementation of this new standard. The team has completed implementation of new lease software that will support the current leasing process, as well as aid in the transition to the new leasing guidance. Although an estimate of the impact of the new leasing standard has not yet been determined, the Company expects a significant new lease asset and related lease liability on the balance sheet due to the number of leased properties the Bank currently has that are accounted for under current operating lease guidance.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments —Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires the measurement of all expected credit losses for certain financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates, but will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. The ASU requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization's portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application will be permitted for specified periods. The Company has an established cross-functional team and project management governance process in place to manage implementation of this new guidance. The team has been working on the process by vetting the data elements and implementing modeling options that are expected to be critical to the new process. An estimate of the impact of this standard has not yet been determined, however, the impact is expected to be significant.

The unrealized losses on the available for sale securities portfolio were caused by changes in market interest rates or the widening of market spreads subsequent to the initial purchase of these securities and are not due to the underlying credit of the issuers. Management monitors the securities within the portfolio, including the published credit ratings of the obligations of state and political subdivisions securities for material rating or outlook changes. As of June 30, 2018, 97% of the obligations of states and political subdivisions securities were rated A3/A- or higher by rating agencies. Substantially all of the Company's obligations of states and political subdivisions are general obligation issuances. All of the available for sale residential mortgage-backed securities and collateralized mortgage obligations portfolio in an unrealized loss position at June 30, 2018 are issued or guaranteed by government sponsored enterprises. It is expected that the mortgage-backed securities and collateralized mortgage obligations securities will be settled at a price at least equal to the amortized cost of each investment.

Because the decline in fair value of the available for sale securities portfolio is attributable to changes in interest rates or widening market spreads and not credit quality, and because the Bank does not intend to sell the securities and it is not more likely than not that the Bank will be required to sell these securities before recovery of their amortized cost basis, which may include holding each security until maturity, these investments are not considered other-than-temporarily impaired.

Allowance for Loan and Lease Loss and Credit Quality

6 Months Ended

Jun. 30, 2018

Receivables [Abstract]

Allowance for Loan and Lease Loss and Credit Quality

Allowance for Loan and Lease Loss and Credit Quality 

The Bank's methodology for assessing the appropriateness of the Allowance for Loan and Lease Loss ("ALLL") consists of three key elements: 1) the formula allowance; 2) the specific allowance; and 3) the unallocated allowance. By incorporating these factors into a single allowance requirement analysis, we believe all risk-based activities within the loan and lease portfolios are simultaneously considered. 

Formula Allowance 

When loans and leases are originated or acquired, they are assigned a risk rating that is reassessed periodically during the term of the loan or lease through the credit review process.  The Bank's risk rating methodology assigns risk ratings ranging from 1 to 10, where a higher rating represents higher risk. The 10 risk rating categories are a primary factor in determining an appropriate amount for the formula allowance. 

The formula allowance is calculated by applying risk factors to various segments of pools of outstanding loans and leases. Risk factors are assigned to each portfolio segment based on management's evaluation of the losses inherent within each segment. Segments with greater risk of loss will therefore be assigned a higher risk factor. 

Base risk – The portfolio is segmented into loan categories, and these categories are assigned a Base risk factor based on an evaluation of the loss inherent within each segment. 

Extra risk – Additional risk factors provide for an additional allocation of ALLL based on the loan and lease risk rating system and loan delinquency, and reflect the increased level of inherent losses associated with more adversely classified loans and leases. 

Risk factors may be changed periodically based on management's evaluation of the following factors: loss experience; changes in the level of non-performing loans and leases; regulatory exam results; changes in the level of adversely classified loans and leases; improvement or deterioration in economic conditions; and any other factors deemed relevant. Additionally, Financial Pacific Leasing Inc. considers additional quantitative and qualitative factors:  migration analysis; a static pool analysis of historic recoveries; and forecasting uncertainties. A migration analysis is a technique used to estimate the likelihood that an account will progress through the various delinquency states and ultimately be charged off.

Specific Allowance 

Regular credit reviews of the portfolio identify loans that are considered potentially impaired. Potentially impaired loans are referred to the ALLL Committee which reviews and approves designated loans as impaired. A loan is considered impaired when, based on current information and events, we determine that we will probably not be able to collect all amounts due according to the loan contract, including scheduled interest payments. When we identify a loan as impaired, we measure the impairment using discounted cash flows or estimated note sale price, except when the sole remaining source of the repayment for the loan is the liquidation of the collateral. In these cases, we use the current fair value of the collateral, less selling costs, instead of discounted cash flows. If we determine that the value of the impaired loan is less than the recorded investment in the loan, we either recognize an impairment reserve as a specific allowance to be provided for in the allowance for loan and lease losses or charge-off the impaired balance on collateral-dependent loans if it is determined that such amount represents a confirmed loss.  Loans determined to be impaired are excluded from the formula allowance so as not to double-count the loss exposure.

The combination of the formula allowance component and the specific allowance component represents the allocated allowance for loan and lease losses. There was no unallocated allowance as of June 30, 2018 and December 31, 2017.

Management believes that the ALLL was adequate as of June 30, 2018. There is, however, no assurance that future loan and lease losses will not exceed the levels provided for in the ALLL and could possibly result in additional charges to the provision for loan and lease losses.

The reserve for unfunded commitments ("RUC") is established to absorb inherent losses associated with our commitment to lend funds, such as with a letter or line of credit. The adequacy of the ALLL and RUC are monitored on a regular basis and are based on management's evaluation of numerous factors. These factors include the quality of the current loan portfolio; the trend in the loan portfolio's risk ratings; current economic conditions; loan concentrations; loan growth rates; past-due and non-performing trends; evaluation of specific loss estimates for all significant problem loans; historical charge-off and recovery experience; and other pertinent information.

There have been no significant changes to the Bank's ALLL methodology or policies in the periods presented.

Asset Quality and Non-Performing Loans and Leases

We manage asset quality and control credit risk through diversification of the loan and lease portfolio and the application of policies designed to promote sound underwriting and loan and lease monitoring practices. The Bank's Credit Quality Administration is charged with monitoring asset quality, establishing credit policies and procedures and enforcing the consistent application of these policies and procedures across the Bank.  Reviews of non-performing, past due loans and leases and larger credits, designed to identify potential charges to the allowance for loan and lease losses, and to determine the adequacy of the allowance, are conducted on an ongoing basis. These reviews consider such factors as the financial strength of borrowers, the value of the applicable collateral, loan and lease loss experience, estimated loan and lease losses, growth in the loan and lease portfolio, prevailing economic conditions and other factors. 

Non-Accrual Loans and Leases and Loans and Leases Past Due

Impaired Loans 

Loans with no related allowance reported generally represent non-accrual loans, which are also considered impaired loans. The Bank recognizes the charge-off on impaired loans in the period it arises for collateral-dependent loans.  Therefore, the non-accrual loans as of June 30, 2018 have already been written down to their estimated net realizable value and are expected to be resolved with no additional material loss, absent further decline in net realizable value.  The valuation allowance on impaired loans primarily represents the impairment reserves on performing restructured loans, and is measured by comparing the present value of expected future cash flows on the restructured loans discounted at the interest rate of the original loan agreement to the loan's carrying value. 

The following tables summarize our impaired loans by loan class as of June 30, 2018 and December 31, 2017:

The impaired loans for which these interest income amounts were recognized primarily relate to accruing restructured loans. 

Credit Quality Indicators 

As previously noted, the Bank's risk rating methodology assigns risk ratings ranging from 1 to 10, where a higher rating represents higher risk.  The Bank differentiates its lending portfolios into homogeneous loans and leases and non-homogeneous loans and leases. Homogeneous loans and leases are not risk rated until they are greater than 30 days past due, and risk rating is based on the past due status of the loan or lease. The 10 risk rating categories can be generally described by the following groupings for loans and leases:

Minimal Risk—A minimal risk loan or lease, risk rated 1, is to a borrower of the highest quality. The borrower has an unquestioned ability to produce consistent profits and service all obligations and can absorb severe market disturbances with little or no difficulty. 

Low Risk—A low risk loan or lease, risk rated 2, is similar in characteristics to a minimal risk loan.  Margins may be smaller or protective elements may be subject to greater fluctuation. The borrower will have a strong demonstrated ability to produce profits, provide ample debt service coverage and to absorb market disturbances. 

Modest Risk—A modest risk loan or lease, risk rated 3, is a desirable loan or lease with excellent sources of repayment and no currently identifiable risk associated with collection. The borrower exhibits a very strong capacity to repay the credit in accordance with the repayment agreement. The borrower may be susceptible to economic cycles, but will have reserves to weather these cycles. 

Average Risk—An average risk loan or lease, risk rated 4, is an attractive loan or lease with sound sources of repayment and no material collection or repayment weakness evident. The borrower has an acceptable capacity to pay in accordance with the agreement. The borrower is susceptible to economic cycles and more efficient competition, but should have modest reserves sufficient to survive all but the most severe downturns or major setbacks.

Acceptable Risk—An acceptable risk loan or lease, risk rated 5, is a loan or lease with lower than average, but still acceptable credit risk. These borrowers may have higher leverage, less certain but viable repayment sources, have limited financial reserves and may possess weaknesses that can be adequately mitigated through collateral, structural or credit enhancement. The borrower is susceptible to economic cycles and is less resilient to negative market forces or financial events. Reserves may be insufficient to survive a modest downturn. 

Watch—A watch loan or lease, risk rated 6, is still pass-rated, but represents the lowest level of acceptable risk due to an emerging risk element or declining performance trend. Watch ratings are expected to be temporary, with issues resolved or manifested to the extent that a higher or lower rating would be appropriate. The borrower should have a plausible plan, with reasonable certainty of success, to correct the problems in a short period of time.

Special Mention—A special mention loan or lease, risk rated 7, has potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or the institution's credit position at some future date. They contain unfavorable characteristics and are generally undesirable. Loans and leases in this category are currently protected but are potentially weak and constitute an undue and unwarranted credit risk, but not to the point of a substandard classification. A special mention loan or lease has potential weaknesses, which if not checked or corrected, weaken the asset or inadequately protect the Bank's position at some future date. For commercial and commercial real estate homogeneous loans and leases to be classified as special mention, risk rated 7, the loan or lease is greater than 30 to 59 days past due from the required payment date at month-end. Residential and consumer and other homogeneous loans are risk rated 7, when the loan is greater than 30 to 89 days past due from the required payment date at month-end. 

Substandard—A substandard asset, risk rated 8, is inadequately protected by the current worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified substandard. Loans and leases are classified as substandard when they have unsatisfactory characteristics causing unacceptable levels of risk. A substandard loan or lease normally has one or more well-defined weaknesses that could jeopardize repayment of the debt. The likely need to liquidate assets to correct the problem, rather than repayment from successful operations is the key distinction between special mention and substandard. Commercial and commercial real estate homogeneous loans and leases are classified as a substandard loan or lease, risk rated 8, when the loan or lease is 60 to 89 days past due from the required payment date at month-end. Residential and consumer and other homogeneous loans are classified as a substandard loan, risk rated 8, when an open-end loan is 90 to 180 days past due from the required payment date at month-end or when a closed-end loan 90 to 120 days is past due from the required payment date at month-end.

Doubtful—Loans or leases classified as doubtful, risk rated 9, have all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors, which may work towards strengthening of the asset, classification as a loss (and immediate charge-off) is deferred until more exact status may be determined. Pending factors include proposed merger, acquisition, liquidation procedures, capital injection, and perfection of liens on additional collateral and refinancing plans. In certain circumstances, a doubtful rating will be temporary, while the Bank is awaiting an updated collateral valuation. In these cases, once the collateral is valued and appropriate margin applied, the remaining un-collateralized portion will be charged-off. The remaining balance, properly margined, may then be upgraded to substandard, however must remain on non-accrual.  Commercial and commercial real estate homogeneous doubtful loans or leases, risk rated 9, are 90 to 179 days past due from the required payment date at month-end. 

Loss—Loans or leases classified as loss, risk rated 10, are considered un-collectible and of such little value that the continuance as an active Bank asset is not warranted. This rating does not mean that the loan or lease has no recovery or salvage value, but rather that the loan or lease should be charged-off now, even though partial or full recovery may be possible in the future. For a commercial or commercial real estate homogeneous loss loan or lease to be risk rated 10, the loan or lease is 180 days and more past due from the required payment date. These loans are generally charged-off in the month in which the 180 day time period elapses. Residential, consumer and other homogeneous loans are risk rated 10, when a loan becomes past due 120 cumulative days from the contractual due date.  Residential and consumer loans secured by real estate are generally charged down to net realizable value in the month in which the loan becomes 180 days past due. All other residential, consumer, and other homogeneous loans are generally charged-off in the month in which the 120 day period elapses. 

Impaired—Loans are classified as impairedwhen, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal and interest when due, in accordance with the terms of the original loan agreement, without unreasonable delay. This generally includes all loans classified as non-accrual and troubled debt restructurings. Impaired loans are risk rated for internal and regulatory rating purposes, but presented separately for clarification.

Troubled Debt Restructurings 

At June 30, 2018 and December 31, 2017, impaired loans of $27.2 million and $32.2 million, respectively, were classified as accruing restructured loans. The restructurings were granted in response to borrower financial difficulty, and generally provide for a temporary modification of loan repayment terms. In order for a newly restructured loan to be considered for accrual status, the loan's collateral coverage generally will be greater than or equal to 100% of the loan balance, the loan is current on payments, and the borrower must either prefund an interest reserve or demonstrate the ability to make payments from a verified source of cash flow. Impaired restructured loans carry a specific allowance and the allowance on impaired restructured loans is calculated consistently across the portfolios. 

There were $537,000 in available commitments for troubled debt restructurings outstanding as of June 30, 2018 and $917,000 as of December 31, 2017. 

The following tables present troubled debt restructurings by accrual versus non-accrual status and by loan class as of June 30, 2018 and December 31, 2017:

Residential, net	6,687		—		6,687
Total, net of deferred fees and costs	$	32,168	$	22,066	$	54,234

The Bank's policy is that loans placed on non-accrual will typically remain on non-accrual status until all principal and interest payments are brought current and the prospect for future payment in accordance with the loan agreement appears relatively certain.  The Bank's policy generally refers to six months of payment performance as sufficient to warrant a return to accrual status.

There were no new restructured loans during the three months ended June 30, 2018. The following tables present newly restructured loans that occurred during the six months ended June 30, 2018 and the three and six months ended June 30, 2017:

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets

Goodwill totaled $1.8 billion at both June 30, 2018 and December 31, 2017, and represents the excess of the total acquisition price paid over the fair value of the assets acquired, net of the fair values of liabilities assumed. Goodwill is not amortized but is evaluated for impairment on an annual basis at December 31 of each year or whenever events or changes in circumstances indicate the carrying value may not be recoverable. No events or circumstances since the December 31, 2017 annual impairment test were noted that would indicate it was more likely than not a goodwill impairment exists.

The following table summarizes the changes in the Company's other intangible assets for the year ended December 31, 2017, and the six months ended June 30, 2018.

Balance, June 30, 2018	$	113,471	$	(86,424	)	$	27,047

Core deposit intangible asset values were determined by an analysis of the cost differential between the core deposits inclusive of estimated servicing costs and alternative funding sources for core deposits acquired through acquisitions. The core deposit intangible assets recorded are amortized on an accelerated basis over a period of approximately 10 years. No impairment losses separate from the scheduled amortization have been recognized in the periods presented.

(2) Represents changes due to collection/realization of expected cash flows over time. 

Information related to our serviced loan portfolio as of June 30, 2018 and December 31, 2017 is as follows: 

(dollars in thousands)	June 30, 2018			December 31, 2017
Balance of loans serviced for others	$	15,508,182		$	15,336,597
MSR as a percentage of serviced loans	1.07		%	1.00		%

The amount of contractually specified servicing fees, late fees and ancillary fees earned, recorded in residential mortgage banking revenue, was $10.4 million and $20.9 million for the three and six months ended June 30, 2018, respectively, as compared to $9.8 million and $19.7 million for the three and six month ended June 30, 2017, respectively. 

Key assumptions used in measuring the fair value of MSR as of June 30, 2018 and December 31, 2017 were as follows: 

	June 30, 2018		December 31, 2017
Constant prepayment rate	11.75	%	12.27	%
Discount rate	9.69	%	9.70	%
Weighted average life (years)	6.6		6.3

A sensitivity analysis of the current fair value to changes in discount and prepayment speed assumptions as of June 30, 2018 and December 31, 2017 is as follows:

(in thousands)	June 30, 2018			December 31, 2017
Constant prepayment rate
Effect on fair value of a 10% adverse change	$	(6,675	)	$	(6,290	)
Effect on fair value of a 20% adverse change	$	(12,853	)	$	(12,093	)
Discount rate
Effect on fair value of a 100 basis point adverse change	$	(6,745	)	$	(5,840	)
Effect on fair value of a 200 basis point adverse change	$	(12,974	)	$	(11,249	)

The sensitivity analysis presents the hypothetical effect on fair value of the MSR. The effect of such hypothetical change in assumptions generally cannot be extrapolated because the relationship of the change in an assumption to the change in fair value is not linear. Additionally, in the analysis, the impact of an adverse change in one assumption is calculated independent of any impact on other assumptions. In reality, changes in one assumption may change another assumption.

(2) Contractual interest rate of junior subordinated debentures. 

(3) Effective interest rate based upon the carrying value as of June 30, 2018. 

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 $14.0 million at June 30, 2018 and $14.3 million at December 31, 2017. As of June 30, 2018, all of the junior subordinated debentures were redeemable at par, at their applicable quarterly or semiannual interest payment dates.

In the first quarter of 2018, the Company paid $10.6 million to redeem the debt securities of the Humboldt Bancorp Statutory Trust I and HB Capital Trust I.

The Company has elected the fair value measurement option for junior subordinated debentures originally issued by the Company (the Umpqua Statutory Trusts) and for junior subordinated debentures acquired from Sterling.

The fair value of the junior subordinated debentures increased for the three and six months ended June 30, 2018, however, based on the application of ASU 2016-01, no loss was recorded in earnings. Instead the loss of $1.5 million and $3.2 million for the three and six months ended, respectively, was recorded in other comprehensive income (loss), net of tax. The loss recorded in earnings resulting from the change in the fair value of these instruments was $1.6 million and $3.1 million for the three and six months ended June 30, 2017, respectively.

Commitments and Contingencies

Commitments and Contingencies 

Lease Commitments — As of June 30, 2018, the Bank leased 221 sites under non-cancelable operating leases. The leases contain various provisions for increases in rental rates, based either on changes in the published Consumer Price Index or a predetermined escalation schedule. Substantially all of the leases provide the Company with the option to extend the lease term one or more times following expiration of the initial term. 

Rent expense for the three and six months ended June 30, 2018 was $9.4 million and $19.0 million, respectively, and for the three and six months ended June 30, 2017 was $9.5 million and $19.2 million, respectively. Rent expense was partially offset by rent income of $648,000 and $1.3 million for the three and six months ended June 30, 2018, respectively, and $494,000 and $1.0 million for the three and six months ended June 30, 2017, respectively.

Financial Instruments with Off-Balance-Sheet Risk — The Company's financial statements do not reflect various commitments and contingent liabilities that arise in the normal course of the Bank's business and involve elements of credit, liquidity, and interest rate risk. 

The following table presents a summary of the Bank's commitments and contingent liabilities:  

(in thousands)	As of June 30, 2018
Commitments to extend credit	$	5,008,398
Forward sales commitments	$	639,160
Commitments to originate residential mortgage loans held for sale	$	338,695
Standby letters of credit	$	69,181

The Bank is a party to financial instruments with off-balance-sheet credit risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and financial guarantees. Those instruments involve elements of credit and interest-rate risk similar to the risk involved in on-balance sheet items recognized in the Condensed Consolidated Balance Sheets. The contract or notional amounts of those instruments reflect the extent of the Bank's involvement in particular classes of financial instruments. 

The Bank's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit, and financial guarantees written, is represented by the contractual notional amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. 

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any covenant or condition established in the applicable contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. While most standby letters of credit are not utilized, a significant portion of such utilization is on an immediate payment basis. The Bank evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if it is deemed necessary by the Bank upon extension of credit, is based on management's credit evaluation of the counterparty. Collateral varies but may include cash, accounts receivable, inventory, premises and equipment and income-producing commercial properties. 

Standby letters of credit and written financial guarantees are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. These guarantees are primarily issued to support public and private borrowing arrangements, including international trade finance, commercial paper, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank holds cash, marketable securities, or real estate as collateral supporting those commitments for which collateral is deemed necessary. There were no financial guarantees in connection with standby letters of credit that the Bank was required to perform on during the three and six months ended June 30, 2018 and June 30, 2017. At June 30, 2018, approximately $43.0 million of standby letters of credit expire within one year, and $26.2 million expire thereafter. The Bank recorded approximately $227,000 and $339,000 in fees associated with standby letters of credit during the three and six months ended June 30, 2018, respectively, compared to $310,000 and $464,000 for the three and six months ended June 30, 2017, respectively.  

Residential mortgage loans sold into the secondary market are sold with limited recourse against the Company, meaning that the Company may be obligated to repurchase or otherwise reimburse the investor for incurred losses on any loans that suffer an early payment default, are not underwritten in accordance with investor guidelines or are determined to have pre-closing borrower misrepresentations. As of June 30, 2018, the Company had a residential mortgage loan repurchase reserve liability of $1.3 million. For loans sold to GNMA, the Bank has a unilateral right, but not the obligation, to repurchase loans that are past due 90 days or more. As of June 30, 2018, the Bank has recorded a liability for the loans subject to this repurchase right of $9.2 million, and has recorded these loans as part of the loan portfolio as if we had repurchased these loans.

Legal Proceedings—Umpqua is involved in legal proceedings occurring in the ordinary course of business. Based on information currently available, advice of counsel and available insurance coverage, we believe that the eventual outcome of actions against the Company or its subsidiaries will not, individually or in the aggregate, have a material adverse effect on our consolidated financial condition. However, it is possible that the ultimate resolution of a matter, if unfavorable, may be material to our results of operations for any particular period.

Concentrations of Credit Risk— The Bank grants real estate mortgage, real estate construction, commercial, agricultural and installment loans and leases to customers throughout Oregon, Washington, California, Idaho, and Nevada. In management's judgment, a concentration exists in real estate-related loans, which represented approximately 75% of the Bank's loan and lease portfolio at June 30, 2018 and December 31, 2017.  Commercial real estate concentrations are managed to assure wide geographic and business diversity. Although management believes such concentrations have no more than the normal risk of collectability, a substantial decline in the economy in general, material increases in interest rates, changes in tax policies, tightening credit or refinancing markets, or a decline in real estate values in the Bank's primary market areas in particular, could have an adverse impact on the repayment of these loans.  Personal and business incomes, proceeds from the sale of real property, or proceeds from refinancing, represent the primary sources of repayment for a majority of these loans. 

The Bank recognizes the credit risks inherent in dealing with other depository institutions. Accordingly, to prevent excessive exposure to any single correspondent, the Bank has established general standards for selecting correspondent banks as well as internal limits for allowable exposure to any single correspondent. In addition, the Bank has an investment policy that sets forth limitations that apply to all investments with respect to credit rating and concentrations with an issuer.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Derivatives 

The Bank may use derivatives to hedge the risk of changes in the fair values of interest rate lock commitments and residential mortgage loans held for sale. None of the Company's derivatives are designated as hedging instruments.  Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in income. The Company primarily utilizes forward interest rate contracts in its derivative risk management strategy. 

The Bank enters into forward delivery contracts to sell residential mortgage loans or mortgage-backed securities to broker/dealers at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential mortgage loan commitments.  Credit risk associated with forward contracts is limited to the replacement cost of those forward contracts in a gain position.  There were no counterparty default losses on forward contracts in the three and six months ended June 30, 2018 and 2017.  Market risk with respect to forward contracts arises principally from changes in the value of contractual positions due to changes in interest rates. The Bank limits its exposure to market risk by monitoring differences between commitments to customers and forward contracts with broker/dealers. In the event the Company has forward delivery contract commitments in excess of available mortgage loans, the Company completes the transaction by either paying or receiving a fee to or from the broker/dealer equal to the increase or decrease in the market value of the forward contract. At June 30, 2018, the Bank had commitments to originate mortgage loans held for sale totaling $338.7 million and forward sales commitments of $639.2 million, which are used to hedge both on-balance sheet and off-balance sheet exposures. 

The Bank executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies.  Those interest rate swaps are simultaneously hedged by offsetting the interest rate swaps that the Bank executes with a third party, such that the Bank minimizes its net risk exposure. As of June 30, 2018, the Bank had 707 interest rate swaps with an aggregate notional amount of $3.5 billion related to this program.  As of December 31, 2017, the Bank had 653 interest rate swaps with an aggregate notional amount of $3.0 billion related to this program.

At both June 30, 2018 and December 31, 2017, the termination value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $29.4 million and $7.2 million, respectively.  The Bank has collateral posting requirements for initial margins with its clearing members and clearing houses and has posted collateral against its obligations under these agreements of $34.8 million and $28.2 million as of June 30, 2018 and December 31, 2017, respectively. 

Umpqua's interest rate swap derivatives are cleared through the Chicago Mercantile Exchange and London Clearing House. These clearing houses characterize the variation margin payments, for derivative contracts that are referred to as settled-to-market, as settlements of the derivative's mark-to-market exposure and not collateral. Umpqua accounts for the variation margin as an adjustment to our cash collateral, as well as a corresponding adjustment to our derivative asset and liability. As ofJune 30, 2018, the variation margin adjustment was a positive adjustment of $16.6 million as compared to a negative adjustment of $20.5 million at December 31, 2017.

The Bank incorporates credit valuation adjustments ("CVA") to appropriately reflect nonperformance risk in the fair value measurement of its derivatives. As of June 30, 2018 and December 31, 2017, the net CVA decreased the settlement values of the Bank's net derivative assets by $213,000 and $1.7 million, respectively. Various factors impact changes in the CVA over time, including changes in the credit spreads of the parties to the contracts, as well as changes in market rates and volatilities, which affect the total expected exposure of the derivative instruments.

The Bank also executes foreign currency hedges as a service for customers. These foreign currency hedges are then offset with hedges with other third-party banks to limit the Bank's risk exposure.

The following table summarizes the types of derivatives, separately by assets and liabilities, and the fair values of such derivatives as of June 30, 2018 and December 31, 2017:

Income Taxes

Income Taxes 

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, as well as in the majority of states and in Canada. As of June 30, 2018, the Company has a net deferred tax liability of $27.3 million, which includes $2.5 million of state net operating loss ("NOL") carry-forwards and $2.0 million of state tax credit carry-forwards. The state NOL carry-forwards expire in tax years 2029-2031 and the state tax credit carry-forwards expire in tax years 2023-2025. The Company believes that it is more likely than not that the benefit from only certain state NOL carry-forwards will not be realized and therefore has provided a valuation allowance of $1.1 million against the deferred tax assets relating to these NOL carry-forwards. 

The Company had gross unrecognized tax benefits of $3.1 million as of June 30, 2018.  If recognized, the unrecognized tax benefit would reduce the 2018 annual effective tax rate by 0.5%. During the three and six months ended June 30, 2018, the Company accrued $5,000 and $30,000 of interest relating to its liability for unrecognized tax benefits.  Interest on unrecognized tax benefits is reported by the Company as a component of tax expense.  As of June 30, 2018, the accrued interest related to unrecognized tax benefits was $383,000.

The Company's consolidated effective tax rate as a percentage of pre-tax income for the three and six months ended June 30, 2018 was 24.7% and 24.3%, respectively, as compared to 35.8% and 36.2% for the three and six months ended June 30, 2017, respectively. The decrease is due to the reduction in the federal income tax rate due to the passage of the Tax Cuts and Jobs Act of 2017.

Earnings Per Share [Abstract]

Earnings Per Common Share

Earnings Per Common Share

Nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are participating securities and are included in the computation of earnings per share pursuant to the two-class method.  The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Certain of the Company's nonvested restricted stock awards qualify as participating securities. 

Net earnings is allocated between the common stock and participating securities pursuant to the two-class method.  Basic earnings per common share is computed by dividing net earnings available to common shareholders by the weighted average number of common shares outstanding during the period, excluding participating nonvested restricted shares. 

Diluted earnings per common share is computed in a similar manner, except that first the denominator is increased to include the number of additional common shares that would have been outstanding if potentially dilutive common shares, excluding the participating securities, were issued using the treasury stock method. For all periods presented, stock options, restricted stock awards and restricted stock units are the only potentially dilutive non-participating instruments issued by the Company.  Next, we determine and include in diluted earnings per common share calculation the more dilutive effect of the participating securities using the treasury stock method or the two-class method. Undistributed losses are not allocated to the nonvested share-based payment awards (the participating securities) under the two-class method as the holders are not contractually obligated to share in the losses of the Company. 

The following is a computation of basic and diluted earnings per common share for the three and six months ended June 30, 2018 and 2017:

The Home Lending segment originates, sells and services residential mortgage loans. The Corporate and other segment includes activities that are not directly attributable to one of the four principal lines of business and includes the operations of Pivotus Ventures, Inc. and the parent company, eliminations and the economic impact of certain assets, capital and support functions not specifically identifiable within the other lines of business.

Management monitors the Company's results using an internal performance measurement accounting system, which provides line of business results and key performance measures. The application and development of these management reporting methodologies is a dynamic process and is subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable segment may be periodically revised retrospectively, if material.

The provision for income taxes is allocated to business segments using a 25% effective tax rate for 2018 and 37% for 2017. The residual income tax expense or benefit arising from tax planning strategies or other tax attributes to arrive at the consolidated effective tax rate is retained in Corporate and Other.

Summarized financial information concerning the Company's reportable segments and the reconciliation to the consolidated financial results is shown in the following tables:

The following methods were used to estimate the fair value of each class of financial instrument that are carried at fair value in the tables above: 

Securities— Fair values for investment securities are based on quoted market prices when available or through the use of alternative approaches, such as matrix or model pricing, or broker indicative bids, when market quotes are not readily accessible or available. Management periodically reviews the pricing information received from the third-party pricing service and compares it to a secondary pricing service, evaluating significant price variances between services to determine an appropriate estimate of fair value to report.

Loans Held for Sale— Fair value for residential mortgage loans originated as held for sale is determined based on quoted secondary market prices for similar loans, including the implicit fair value of embedded servicing rights.

Residential Mortgage Servicing Rights— The fair value of MSR is estimated using a discounted cash flow model. Assumptions used include market discount rates, anticipated prepayment speeds, delinquency and foreclosure rates, and ancillary fee income net of servicing costs. This model is periodically validated by an independent model validation group. The model assumptions and the MSR fair value estimates are also compared to observable trades of similar portfolios as well as to MSR broker valuations and industry surveys, as available. Management believes the significant inputs utilized are indicative of those that would be used by market participants. 

Junior Subordinated Debentures— The fair value of junior subordinated debentures is estimated using an income approach valuation technique.  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. The Company periodically utilizes a valuation firm to determine or validate the reasonableness of inputs and factors that are used to determine the fair value. 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.  Due to credit concerns in the capital markets and inactivity in the trust preferred markets that have limited the observability of market spreads, we have classified this as a Level 3 fair value measure.  

Derivative Instruments— The fair value of the interest rate lock commitments and forward sales commitments are estimated using quoted or published market prices for similar instruments, adjusted for factors such as pull-through rate assumptions based on historical information, where appropriate.  The pull-through rate assumptions are considered Level 3 valuation inputs and are significant to the interest rate lock commitment valuation; as such, the interest rate lock commitment derivatives are classified as Level 3. The fair value of the interest rate swaps is determined using a discounted cash flow technique incorporating credit valuation adjustments to reflect nonperformance risk in the measurement of fair value. Although the Bank has determined that the majority of the inputs used to value its interest rate swap derivatives fall within Level 2 of the fair value hierarchy, the CVA associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of June 30, 2018, the Bank has assessed the significance of the impact of the CVA on the overall valuation of its interest rate swap positions and has determined that the CVA are not significant to the overall valuation of its interest rate swap derivatives. As a result, the Bank has classified its interest rate swap derivative valuations in Level 2 of the fair value hierarchy.   

Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs (Level 3) 

The following table provides a description of the valuation technique, significant unobservable inputs, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring basis at June 30, 2018: 

Financial Instrument	Valuation Technique	Unobservable Input	Weighted Average
Residential mortgage servicing rights	Discounted cash flow
		Constant Prepayment Rate	11.75%
		Discount Rate	9.69%
Interest rate lock commitment	Internal Pricing Model
		Pull-through rate	88.92%
Junior subordinated debentures	Discounted cash flow
		Credit Spread	4.97%

Generally, any significant increases in the constant prepayment rate and discount rate utilized in the fair value measurement of the residential mortgage servicing rights will result in negative fair value adjustments (and a decrease in the fair value measurement). Conversely, a decrease in the constant prepayment rate and discount rate will result in a positive fair value adjustment (and increase in the fair value measurement).

An increase in the pull-through rate utilized in the fair value measurement of the interest rate lock commitment derivative will result in positive fair value adjustments (and an increase in the fair value measurement). Conversely, a decrease in the pull-through rate will result in a negative fair value adjustment (and a decrease in the fair value measurement).

Management believes that the credit risk adjusted spread utilized in the fair value measurement of the junior subordinated debentures carried at fair value is indicative of the nonperformance risk premium a willing market participant would require under current market conditions, that is, the inactive market. Management attributes the change in fair value of the junior subordinated debentures during the period to market changes in the nonperformance expectations and pricing of this type of debt. The widening of the credit risk adjusted spread above the Company's contractual spreads has primarily contributed to the positive fair value adjustments.  Future contractions in the instrument-specific credit risk adjusted spread relative to the spread currently utilized to measure the Company's junior subordinated debentures at fair value as of June 30, 2018, or the passage of time, will result in negative fair value adjustments.  Generally, an increase in the credit risk adjusted spread and/or the forward swap interest rate curve will result in positive fair value adjustments (and decrease the fair value measurement). Conversely, a decrease in the credit risk adjusted spread and/or the forward swap interest rate curve will result in negative fair value adjustments (and increase the fair value measurement).

The following tables provide a reconciliation of assets and liabilities measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the three and six months ended June 30, 2018 and 2017:

Changes in residential mortgage servicing rights carried at fair value are recorded in residential mortgage banking revenue within non-interest income. Gains (losses) on interest rate lock commitments carried at fair value are recorded in residential mortgage banking revenue within non-interest income. The contractual interest expense on the junior subordinated debentures is recorded on an accrual basis as interest on junior subordinated debentures within interest expense. Settlements related to the junior subordinated debentures represent the payment of accrued interest that is embedded in the fair value of these liabilities. 

For 2017, the Company recorded gains (losses) on junior subordinated debentures carried at fair value in non-interest income. As discussed in Note 1, Summary of Significant Accounting Policies, the Company applied new guidance to the accounting for the gain/loss on fair value of the junior subordinated debentures. For the three and six months ended June 30, 2018, the change in fair value is attributable to the change in the instrument specific credit risk of the junior subordinated debentures, accordingly, the losses on fair value of junior subordinated debentures for the three and six months ended June 30, 2018 of $1.5 million and $3.2 million, respectively, are recorded net of tax as an other comprehensive loss of $1.1 million and $2.4 million, respectively.

From time to time, certain assets are measured at fair value on a nonrecurring basis.  These adjustments to fair value generally result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairment, typically on collateral dependent loans. 

Fair Value of Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

The following tables present information about the Company's assets and liabilities measured at fair value on a nonrecurring basis for which a nonrecurring change in fair value has been recorded during the reporting period.  The amounts disclosed below represent the fair values at the time the nonrecurring fair value measurements were made, and not necessarily the fair value as of the dates reported upon.

The following provides a description of the valuation technique and inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a nonrecurring basis. Unobservable inputs and qualitative information about the unobservable inputs are not presented as the fair value is determined by third-party information. The loans and leases amounts above represent impaired, collateral dependent loans that have been adjusted to fair value.  When we identify a collateral dependent loan as impaired, we measure the impairment using the current fair value of the collateral, less selling costs. Depending on the characteristics of a loan, the fair value of collateral is generally estimated by obtaining external appraisals, but in some cases, the value of the collateral may be estimated as having little to no value. If we determine that the value of the impaired loan is less than the recorded investment in the loan, we recognize this impairment and adjust the carrying value of the loan to fair value through the allowance for loan and lease losses.  The loss represents charge-offs or impairments on collateral dependent loans for fair value adjustments based on the fair value of collateral.

The other real estate owned amount above represents impaired real estate that has been adjusted to fair value.  Other real estate owned represents real estate which the Bank has taken control of in partial or full satisfaction of loans. At the time of foreclosure, other real estate owned is recorded at the lower of the carrying amount of the loan or fair value less costs to sell, which becomes the property's new basis. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for loan and lease losses. After foreclosure, management periodically performs valuations such that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Fair value adjustments on other real estate owned are recognized within net loss on real estate owned. The loss represents impairments on other real estate owned for fair value adjustments based on the fair value of the real estate. 

Fair Value Option

The following table presents the difference between the aggregate fair value and the aggregate unpaid principal balance of loans held for sale accounted for under the fair value option as of June 30, 2018 and December 31, 2017:

(in thousands)	June 30, 2018						December 31, 2017
	Fair Value		Aggregate Unpaid Principal Balance		Fair Value Less Aggregate Unpaid Principal Balance		Fair Value		Aggregate Unpaid Principal Balance		Fair Value Less Aggregate Unpaid Principal Balance
Loans held for sale	$	432,642	$	418,442	$	14,200	$	259,518	$	250,721	$	8,797

Residential mortgage loans held for sale accounted for under the fair value option are measured initially at fair value with subsequent changes in fair value recognized in earnings. Gains and losses from such changes in fair value are reported as a component of residential mortgage banking revenue, net in the Condensed Consolidated Statements of Income. For the three and six months ended June 30, 2018, the Company recorded a net increase in fair value of $5.7 million and $5.4 million, respectively. For the three and six months ended June 30, 2017, the Company recorded a net increase in fair value of $2.2 million and $7.1 million, respectively.

The Company selected the fair value measurement option for existing junior subordinated debentures (the Umpqua Statutory Trusts) and for junior subordinated debentures acquired from Sterling. The remaining junior subordinated debentures were acquired through previous business combinations and were measured at fair value at the time of acquisition and subsequently measured at amortized cost.

Accounting for the selected junior subordinated debentures 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.

Due to inactivity in the junior subordinated debenture market and the lack of 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, evaluates 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. We also consider changes in the interest rate environment in our valuation, specifically the absolute level and the shape of the slope of the forward swap curve.

(a) Not within scope of ASC 606

Deposit service charges

Umpqua earns fees from its deposit customers for account maintenance, transaction-based and overdraft services. Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis. The performance obligation is satisfied and the fees are recognized on a monthly basis as the service period is completed. Transaction-based fees on deposits accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds fees, overdraft fees, and wire fees. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer.

Debit and ATM interchange fee income and expenses

Debit and ATM interchange income represent fees earned when a debit card issued by Umpqua is used. Umpqua earns interchange fees from debit cardholder transactions through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders’ debit card. Certain expenses directly associated with the credit and debit card are recorded on a net basis with the interchange income.

Brokerage revenue

As of the three and six months ended June 30, 2018, Umpqua had revenues of $4.2 million and $8.4 million, respectively, for the performance of brokerage services for its clients through Umpqua Investments. Brokerage fees consist of transaction fees earned from asset management, trade execution and administrative fees from investments. Asset management fees are variable, since they are based on the underlying portfolio value, which is subject to market conditions and amounts invested by clients. Asset management fees are recognized over the period that services are provided, and when the portfolio values are known or can be estimated at the end of each quarter. Brokerage transaction fees are fixed and determinable, based on security type and trade volume, and are recognized upon trade execution. In addition, revenues are earned from selling insurance and annuity policies. The amount of revenue earned is determined by the value and type of each instrument sold and is recognized when the policy is in force.

Merchant fee income

Merchant fee income represents fees earned by Umpqua for card payment services provided to its merchant customers. Umpqua outsources these services to a third party to provide card payment services to these merchants. The third party provider passes the payments made by the merchants through to Umpqua. Umpqua, in turn, pays the third party provider for the services it provides to the merchants. These payments to the third party provider are recorded as expenses as a net reduction against fee income. In addition, a portion of the payment received represents interchange fees which are passed through to the card issuing bank. Income is primarily earned based on the dollar volume and number of transactions processed. The performance obligation is satisfied and the related fee is earned when each payment is accepted by the processing network. For the three and six months ended June 30, 2018, Umpqua had merchant processing fee revenue of $1.2 million and $2.1 million, respectively, included in other income.

Credit card and interchange income and expenses

Credit card interchange income represent fees earned when a credit card issued by the Company is used. Similar to the debit card interchange, Umpqua earns an interchange fee for each transaction made with Umpqua's branded credit cards. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the cardholders’ credit card. Certain expenses and rebates directly related to the credit card interchange contract are recorded net to the interchange income. For the three and six months ended June 30, 2018, credit card and interchange income included in other income was $1.8 million and $3.5 million, respectively.

Gain/loss on other real estate owned, net

Umpqua records a gain or loss from the sale of other real estate owned when control of the property transfers to the buyer, which generally occurs at the time of an executed deed of trust. When Umpqua finances the sale of other real estate owned to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the other real estate owned asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on sale, Umpqua adjusts the transaction price and related gain or loss on sale if a significant financing component is present.

Derivatives 

The Bank may use derivatives to hedge the risk of changes in the fair values of interest rate lock commitments and residential mortgage loans held for sale. None of the Company's derivatives are designated as hedging instruments.  Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in income. The Company primarily utilizes forward interest rate contracts in its derivative risk management strategy.
