Commitments and Contingencies

Lease Commitments — As of March 31, 2017, the Bank leased 251 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, 2017 was $9.8 million and for the three months ended March 31, 2016 was $9.7 million. Rent expense was partially offset by rent income of $513,000 for the three months ended March 31, 2017 and $503,000 for the three months ended March 31, 2016.

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, 2017
Commitments to extend credit	$	4,145,219
Forward sales commitments	$	626,430
Commitments to originate residential mortgage loans held for sale	$	447,676
Standby letters of credit	$	69,829

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, 2017 and March 31, 2016. At March 31, 2017, approximately $50.4 million of standby letters of credit expire within one year, and $19.5 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 Bank recorded approximately $154,000 and $110,000 in fees associated with standby letters of credit during the three months ended March 31, 2017 and 2016, 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 March 31, 2017, the Company had a residential mortgage loan repurchase reserve liability of $1.1 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 March 31, 2017, the Bank has recorded a liability for the loans subject to this repurchase right of $5.3 million, and has recorded these loans as part of the loan portfolio as if we had repurchased these loans.

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

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 March 31, 2017 and 76% at December 31, 2016. 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.
