Commitments and Contingencies

Lease Commitments — As of March 31, 2015, the Bank leased 281 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 months ended March 31, 2015 was $9.3 million and for the three months ended March 31, 2014 was $5.0 million. Rent expense was partially offset by rent income for the three months ended March 31, 2015 of $118,000 and for the three months ended March 31, 2014 of $177,000.

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 March 31, 2015
Commitments to extend credit	$	2,996,411
Commitments to extend overdrafts	$	940,366
Forward sales commitments	$	692,900
Commitments to originate residential mortgage loans held for sale	$	458,378
Standby letters of credit	$	56,622

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 financial guarantees written 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. The Bank was not required to perform on any financial guarantees during the three months ended March 31, 2015 and March 31, 2014. At March 31, 2015, approximately $47.8 million of standby letters of credit expire within one year, and $8.8 million expire thereafter. Upon issuance, the Bank recognizes a liability equivalent to the amount of fees received from the customer for these standby letter of credit commitments. Fees are recognized ratably over the term of the standby letter of credit. The estimated fair value of guarantees associated with standby letters of credit was $1.1 million as of March 31, 2015.

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 March 31, 2015, the Company had a residential mortgage loan repurchase reserve liability of $3.3 million.

Legal Proceedings—The Bank owns 483,806 shares of Class B common stock of Visa Inc. which are convertible into Class A common stock at a conversion ratio of 1.6483 per Class A share. As of March 31, 2015, the closing value of the Class A shares was $65.48 per share. Utilizing the conversion ratio, the value of unredeemed Class A equivalent shares owned by the Bank was $52.2 million as of March 31, 2015, and has not been reflected in the accompanying financial statements. The shares of Visa Inc. Class B common stock are restricted and may not be transferred. Visa member banks are required to fund an escrow account to cover settlements, resolution of pending litigation and related claims. If the funds in the escrow account are insufficient to settle all the covered litigation, Visa Inc. may sell additional Class A shares and use the proceeds to settle litigation, thereby reducing the conversion ratio. If funds remain in the escrow account after all litigation is settled, the Class B conversion ratio will be increased to reflect that surplus.

On July 13, 2012, Visa Inc. announced that it had entered into a memorandum of understanding obligating it to enter into a settlement agreement to resolve the multi-district interchange litigation brought by the class plaintiffs in the matter styled In re Payment Card Interchange Fee and Merchant Discount Antitrust Litigation, Case No. 5-MD-1720 (JG) (JO) pending in the U.S. District Court for the Eastern District of New York. The claims originally were brought by a class of U.S. retailers in 2005. The settlement was approved by the court on December 13, 2013, but that decision is currently being appealed. Visa's share of the previously agreed settlement amount was approximately $4.4 billion. However, because of the pending appeal, the ultimate effect of this settlement on the value of the Bank's Class B common stock is unknown at this time.

In the ordinary course of business, various claims and lawsuits are brought by and against the Company and its subsidiaries, including the Bank and Umpqua Investments. In the opinion of management, there is no pending or threatened proceeding in which an adverse decision could result in a material adverse change in the Company's consolidated financial condition or results of operations.

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 80% of the Bank's loan and lease portfolio at March 31, 2015 and December 31, 2014. 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.
