	Description of Business, Basis of Presentation and Significant Accounting Policies
	(a) Description of Business
	Heritage Financial Corporation (the “Company”) is a bank holding company that was incorporated in the State of Washington in August 1997. The Company is primarily engaged in the business of planning, directing and coordinating the business activities of its wholly-owned subsidiary Heritage Bank (the “Bank”). The Bank is a Washington-chartered commercial bank and its deposits are insured by the FDIC under the Deposit Insurance Fund (“DIF”). The Bank is headquartered in Olympia, Washington and conducts business from its thirty-five branch offices located throughout Washington state and the greater Portland, Oregon area. The Bank’s business consists primarily of lending and deposit relationships with small businesses and their owners in its market areas and attracting deposits from the general public. The Bank also makes real estate construction and land development loans and consumer loans and originates first mortgage loans on residential properties located in western and central Washington State and the greater Portland, Oregon area.
	The Company has expanded its footprint through acquisitions beginning with the FDIC-assisted acquisition of Cowlitz Bank, a Washington chartered commercial bank headquartered in Longview, Washington effective on July 30, 2010. Heritage Bank entered into a definitive agreement with the FDIC, pursuant to which Heritage Bank acquired certain assets and assumed certain liabilities of Cowlitz Bank (the “Cowlitz Acquisition”). The Cowlitz Acquisition included nine branches of Cowlitz Bank, including its division Bay Bank, which opened as branches of Heritage Bank on August 2, 2010. It also included the Trust Services Division of Cowlitz Bank.
	Effective November 5, 2010, Heritage Bank entered into a definitive agreement with the FDIC, pursuant to which Heritage Bank acquired certain assets and assumed certain liabilities of Pierce Commercial Bank, a Washington chartered commercial bank headquartered in Tacoma, Washington (the “Pierce Commercial Acquisition”). The Pierce Commercial Acquisition included one branch, which opened as a branch of Heritage Bank as of November 8, 2010.
	On September 14, 2012, the Company and the Bank entered into a definitive agreement to acquire Northwest Commercial Bank (“NCB”), a Washington chartered commercial bank headquartered in Lakewood, Washington (the “NCB Acquisition”). The NCB Acquisition was completed on January 9, 2013, with the merger of NCB into Heritage Bank. See Note 2, “Business Combinations” for additional information.
	On March 11, 2013, the Company entered into a definitive agreement to acquire Valley Community Bancshares, Inc. ("Valley" or "Valley Community Bancshares") and its wholly-owned subsidiary, Valley Bank, both headquartered in Puyallup, Washington (the “Valley Acquisition”). The Valley Acquisition was completed on July 15, 2013. See Note 2, “Business Combinations” for additional information.
	On April 8, 2013, the Company announced the proposed merger of its two wholly-owned bank subsidiaries Central Valley Bank and Heritage Bank, with Central Valley Bank merging into Heritage Bank. The common control merger was completed on June 19, 2013 and on a consolidated basis had no accounting impact on the Company. Central Valley Bank now operates as a division of Heritage Bank.
	On October 23, 2013, the Company, along with the Bank, and Washington Banking Company (“Washington Banking”) and its wholly owned subsidiary bank, Whidbey Island Bank ("Whidbey") jointly announced the signing of a merger agreement under which Heritage and Washington Banking will enter into a strategic merger with Washington Banking merging into Heritage. Immediately following the merger, Whidbey will merge into the Bank. Washington Banking branches will adopt the Heritage Bank name in all markets, with the exception of six branches in Whidbey Island markets which will continue to operate using the Whidbey Island Bank name. The corporate headquarters of the combined company will be in Olympia, Washington. The merger is anticipated to be completed in the second quarter of 2014. See "Note 22 - Proposed Merger" for additional information.
	(b) Basis of Presentation
	The accounting and reporting policies of the Company and its subsidiary confirm to U.S. Generally Accepted Accounting Principles (“GAAP”). In preparing the Consolidated Financial Statements management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of financial statements and the reported amounts of income and expenses during the reporting periods. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, other than temporary impairments in the fair value of investment securities, expected cash flows of purchased loans and related indemnification asset, fair value measurements, stock-based compensation, impairment of goodwill and other intangible assets and income taxes. Actual results could differ from these estimates.
	The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiary. All significant intercompany balances and transactions among the Company and its subsidiary have been eliminated in consolidation.
	Certain prior year amounts have been reclassified to conform to the current period’s presentation. Reclassifications had no effect on prior year net income or stockholders’ equity.
	(c) Significant Accounting Policies
	Cash and Cash Equivalents
	For purposes of reporting cash flows, cash and cash equivalents includes cash on hand and in banks, interest earning deposits with original maturities of 90 days or less, and federal funds sold. Net cash flows are reported for customer loan and deposit transactions, other interest bearing deposits, federal funds sold and repurchase agreements.
	Investment Securities
	The Company identifies investments as held to maturity or available for sale at the time of acquisition. Securities are classified as held to maturity when the Company has the ability and positive intent to hold them to maturity. Securities classified as available for sale are available for future liquidity requirements and may be sold prior to maturity.
	Investment securities held to maturity are recorded at cost, adjusted for amortization of premiums or accretion of discounts using the interest method. Securities available for sale are carried at fair value. Unrealized gains and losses on securities available for sale are excluded from earnings and are reported in other comprehensive income, net of related income taxes. Realized gains and losses on sale of investment securities are computed on the specific identification method.
	Management evaluates securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Although these evaluations involve significant judgment, an unrealized loss in the fair value of a debt security is generally deemed to be temporary when the fair value of the security is below the carrying value primarily due to changes in interest rates, there has not been significant deterioration in the financial condition of the issuer, and it is not more likely than not that the Company will be required to sell the security before the anticipated recovery of its remaining carrying value. If any of these criteria is not met, the impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. An unrealized loss in the value of an equity security is generally considered temporary when the fair value of the security is below the carrying value primarily due to current market conditions and not deterioration in the financial condition of the issuer, and it is not more likely than not that the Company will be required to sell the security before the anticipated recovery of its remaining carrying value. Other factors that may be considered in determining whether a decline in the value of either a debt or an equity security is “other than temporary” include ratings by recognized rating agencies; actions of commercial banks or other lenders relative to the continued extension of credit facilities to the issuer of the security; the financial condition, capital strength and near-term prospects of the issuer and recommendations of investment advisors or market analysts. If any of these criteria is not met, the entire difference between amortized cost and fair value is recognized as impairment through earnings, and a new cost basis is established for the security. Continued deterioration of market conditions could result in additional impairment losses recognized within the investment portfolio.
	Loans Receivable and Loans Held for Sale
	Loans Held for Sale:
	Mortgage loans held for sale are carried at the lower of amortized cost or market value determined on an aggregate basis. Any loan that management determines will not be held to maturity is classified as held for sale at the time of origination, purchase or securitization, or when such decision is made. Unrealized losses on such loans are included in income.
	Originated Loans:
	Originated loans are generally recorded at their outstanding principal balance adjusted for charge-offs, the allowance for loan losses and deferred fees and costs. Interest on loans is calculated using the simple interest method based on the daily balance of the principal amount outstanding and is credited to income as earned. Loans are considered past due or delinquent when principal or interest payments are past due 30 days or more. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. Delinquent loans may remain on accrual status between 30 days and 89 days past due. The accrual of interest is discontinued at the time the loan is 90 days delinquent unless the credit is well secured and in the process of collection. Loans are placed on nonaccrual at an earlier date if collection of the contractual principal or interest is doubtful. All interest accrued but not collected on loans deemed nonaccrual during the period is reversed against interest income in that period. The interest payments received on nonaccrual loans is accounted for on the cost-recovery method whereby the interest payment is applied to the principal balances. Loans may be returned to accrual status when improvements in credit quality eliminate the doubt as to the full collectability of both interest and principal and a period of sustained performance has occurred. Substantially all loans that are nonaccrual are also impaired. Income recognition on impaired loans conforms to that used on nonaccrual loans
	Loans are charged-off if collection of the contractual principal or interest as scheduled in the loan agreement is doubtful. Credit card loans and other consumer loans are typically charged-off no later than 180 days past due.
	Purchased Covered and Purchased Non-Covered Loans:
	Loans acquired in a business combination are designated as “purchased” loans. These loans are recorded at their fair value at acquisition date, factoring in credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for loan losses is not carried over or recorded as of the acquisition date. Purchased loans subject to FDIC shared-loss agreements are identified as “covered” on the Consolidated Statements of Financial Condition, while purchased loans not subject to FDIC shared-loss agreements are referred to as “non-covered”. The covered loans have an additional evaluation separate from originated and purchased non-covered loans as they have shared-loss attributes which may reduce the Bank’s risk of loss. For further information see Note 7, “FDIC Indemnification Asset”.
	Loans purchased with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are accounted for under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“FASB ASC”) 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, formerly AICPA SOP 03-3 Accounting for Certain Loans or Debt Securities Acquired in a Transfer. These loans are identified as “purchased impaired” loans. In situations where such loans have similar risk characteristics, loans may be aggregated into pools to estimate cash flows. A pool is accounted for as a single asset with a single interest rate, cumulative loss rate and cash flow expectation. Expected cash flows at the acquisition date in excess of the fair value of loans are considered to be accretable yield, which is recognized as interest income over the life of the loan or pool using a level yield method if the timing and amount of the future cash flows of the pool is reasonably estimable.
	The cash flows expected over the life of the purchased impaired loan or pool are estimated quarterly using an internal cash flow model that projects cash flows and calculates the carrying values of the pools, book yields, effective interest income and impairment, if any, based on pool level events. Assumptions as to default rates, loss severity and prepayment speeds are utilized to calculate the expected cash flows. To the extent actual or projected cash flows are less than previously estimated, additional provisions for loan losses on the purchased loan portfolios will be recognized immediately into earnings. To the extent actual or projected cash flows are more than previously estimated, the increase in cash flows is recognized immediately as a recapture of provision for loan losses up to the amount of any provision previously recognized for that pool of loans, if any, then prospectively recognized in interest income as a yield adjustment. Any disposals of loans, including sales of loans, and payments in full or foreclosures result in the removal of the loan from the loan pool at the carrying amount.
	Loans accounted for under FASB ASC 310-30 are generally considered accruing and performing loans as the loans accrete interest income over the estimated life of the loan when cash flows are reasonably estimable. Accordingly, purchased impaired loans that are contractually past due are still considered to be accruing and performing loans. If the timing and amount of cash flows is not reasonably estimable, the loans may be classified as nonaccrual loans and interest income may be recognized on a cash basis or as a reduction of the principal amount outstanding.
	Loans purchased that are not accounted for under FASB ASC 310-30 are accounted for under FASB ASC 310-20, Receivables—Nonrefundable fees and Other Costs, formerly SFAS 91 Nonrefundable fees and Other Costs, which considers the contractual cash flows. These loans are identified as “purchased other” loans, and are initially recorded at their fair value, which is estimated using an internal cash flow model and assumptions similar to the FASB ASC 310-30 loans. The difference between the estimated fair value and the unpaid principal balance at acquisition date is recognized as interest income over the life of the loan using an effective interest method for non-revolving credits or a straight-line method, which approximates the effective interest method, for revolving credits. Any unrecognized discount for a loan that is subsequently repaid or fully charged-off will be recognized immediately into income.
	Impaired Loans and Troubled Debt Restructures
	Impaired Loans:
	A loan is considered impaired when, based on current information and events, it is probable the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrowers, including length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amounts of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral (less cost to sell) if the loan is collateral dependent.
	Troubled Debt Restructures:
	A troubled debt restructured loan (“TDR”) is a restructuring in which the Bank, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to a borrower that it would not otherwise consider. These concessions may include changes of the interest rate, forbearance of the outstanding principal or accrued interest, extension of the maturity date, delay in the timing of the regular payment, or any other actions intended to minimize potential losses. The Bank does not forgive principal for a majority of their TDRs, but in those situations where principal is forgiven, the entire amount of such principal forgiveness is immediately charged off to the extent not done so prior to the modification. The Bank also considers insignificant delays in payments when determining if a loan should be classified as a TDR.
	A loan that has been placed on nonaccrual status that is subsequently restructured will usually remain on nonaccrual status until the borrower is able to demonstrate repayment performance in compliance with the restructured terms for a sustained period, typically for six months. A restructured loan may return to accrual status sooner based on other significant events or mitigating circumstances. A loan that has not been placed on nonaccrual status may be restructured and such loan may remain on the accrual status after such restructuring. In these circumstances, the borrower has made payments before and after the restructuring. Generally, this restructuring involves a reduction in the loan interest rate and/or a change to interest-only payments for a period of time. The restructured loan is considered impaired despite the accrual status and a specific valuation allowance is calculated similar to the impaired loans.
	A TDR is considered defaulted if, during the 12-month period after the restructure, the loan has not performed in accordance to the restructured terms. Defaults include loans whose payments are 90 days or more past due and loans whose revised maturity date passed and no further modifications will be granted for that borrower.
	A loan may subsequently be excluded from the TDR disclosures if (i) the restructured interest rate was greater than or equal to the interest rate of a new loan with comparable risk at the time of the restructure, and (ii) the loan is no longer impaired based on the terms of the restructured agreement. The Bank's policy is that the borrower must demonstrate a sustained period, typically six consecutive months, of payments in accordance with the modified loan before it can be reviewed for removal from the TDR disclosure under the second criteria. However, the loan must be reported as a TDR in at least one annual report on Form 10-K. Once a loan has been classified as a TDR, it will continue to be disclosed as an impaired loan until paid off or charged-off, even if the loan subsequently is no longer disclosed as a TDR.
	Loan Fees
	Loan origination fees and certain direct origination costs are deferred and amortized as an adjustment of the yields of the loans over their contractual lives, adjusted for prepayment of the loans, using the effective interest method or the straight-line method, which approximates the effective interest method. In the event loans are sold, the net deferred loan origination fees or costs are recognized as a component of the gains or losses on the sales of loans.
	Allowance for Loan Losses
	Allowance for Loan Losses on Originated Loans:
	The allowance for loan losses is a reserve established through a provision for loan losses charged to expense, which represents management’s best estimate of probable losses that have been incurred within the existing portfolio of originated loans. For further information on the policy on purchased loans, see “Allowance for Loan Losses on Purchased Loans” below. The allowance, in the judgment of management, is necessary to reserve for estimated loan losses and risks inherent in the loan portfolio. The Company’s allowance for loan losses methodology includes allowance allocations calculated in accordance with FASB ASC 310, Receivables and allowance allocations calculated in accordance with FASB ASC 450, Contingencies. Accordingly, the methodology is based on historical loss experience by type of credit and internal risk grade, specific homogeneous risk pools and specific loss allocations, with adjustments for current events and conditions. The Company’s process for determining the appropriate level of the allowance for loan losses is designed to account for credit deterioration as it occurs. The provision for loan losses reflects loan quality trends, including the levels of and trends related to nonaccrual loans, past due loans, potential problem loans, criticized loans and net charge-offs or recoveries, among other factors. The provision for loan losses also reflects the totality of actions taken on all loans for a particular period. In other words, the amount of the provision reflects not only the necessary increases in the allowance for loan losses related to newly identified criticized loans, but it also reflects actions taken related to other loans including, among other things, any necessary increases or decreases in required allowances for specific loans or loan pools. Losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance.
	The level of the allowance reflects management’s continuing evaluation of known and inherent risks in the loan portfolio. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off.
	The Company’s allowance for loan losses consists of three elements: (i) specific valuation allowances determined in accordance with FASB ASC 310 based on probable losses on specific loans; (ii) historical loss factor determined in accordance with FASB ASC 450 based on historical loan loss experience for similar loans with similar characteristics and trends; and (iii) an environmental loss factor to reflect the impact of current conditions, as determined in accordance with FASB ASC 450 based on general economic conditions and other qualitative risk factors both internal and external to the Company. The historical loss factor and environmental loss factor are combined and multiplied against the outstanding principal balance of loans in the pool of similar loans with similar characteristics. The Company’s pools of similar loans are grouped by class of loan.
	The allowances established for probable losses on specific loans are based on a regular analysis and evaluation of problem loans. Loans are classified based on an internal credit risk grading process that evaluates, among other things: (i) the obligor’s ability to repay; (ii) the underlying collateral, if any; and (iii) the economic environment and industry in which the borrower operates. This analysis is performed at the loan officer level for all loans. When a loan is performing but has an assigned risk grade greater than pass, the loan officer analyzes the loan to determine an appropriate monitoring and collection strategy. When a loan is nonperforming or has been classified as a nonaccrual loan, a member from the special assets department will analyze the loan to determine if it is impaired. If the loan is considered impaired, the special asset department will evaluate the need for a specific valuation allowance on the loan. Specific valuation allowances are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies and economic conditions affecting the borrower’s industry, among other things.
	Historical loss factors are calculated based on the historical loss experience and recovery experience of specific classes of loans. The Company calculates historical loss ratios for the classes of loans based on the proportion of actual charge-offs and recoveries experienced to the total population of loans in the pool for a rolling twelve quarter average.
	Environmental loss factors are based on general economic conditions and other qualitative risk factors both internal and external to the Company. In general, such valuation allowances are determined by evaluating, among other things: (i) levels of and trend in delinquencies and impaired loans; (ii) levels and trends in charge-offs and recoveries; (iii) effects of changes in risk selection and underwriting standards, and other changes in lending policies, procedures, and practices; (iv) experience, ability, and depth of lending management and other relevant staff; (v) national and local economic trends and conditions; (vi) external factors such as competition, legal, and regulatory and; (vii) effects of changes in credit concentrations. Management evaluates the degree of risk that each one of these components has on the quality of the loan portfolio on a quarterly basis. Each component is determined to be on a scale of risk. The results are then utilized in a matrix to determine an appropriate environmental loss factor for each class of loan. An additional environmental factor is added after the calculated matrix factor if the specific loan is risk graded greater than watch.
	The allowance for loan loss evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. While management utilizes its best judgment and information available to recognize losses on loans, future additions to the allowance may be necessary based on declines in local and national economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses. Such agencies may require the Bank to make adjustments to the allowance based on their judgments about information available to them at the time of their examinations. The Company believes the allowance for loan losses is appropriate given all the above considerations.
	The Bank is also party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheet. The Company has a policy in which it evaluates the risk on a quarterly basis, and provides for an allowance for credit losses, as necessary. The methodology is similar to the allowance for loan losses, and includes an estimate of the probability of drawdown of the loan commitment. Based on its analysis, the Company has recorded an allowance for off-balance sheet financial instruments of $110,000 and $75,000 as of December 31, 2013 and 2012, respectively.
	Allowance for Loan Losses on Purchased Loans:
	The purchased loans acquired in all the Acquisitions are subject to the Company’s internal and external credit review. Under the accounting guidance of FASB ASC 310-30, the allowance for loan losses on purchased impaired loans is measured at each financial reporting period, or measurement date, based on expected cash flows. If and when credit deterioration, or decreases in expected cash flows initially estimated, occurs subsequent to the acquisition date, a provision for loan losses for purchased loans will be charged to earnings as of the measurement date. For the purchased covered loans, a provision for loan losses will be charged to earnings for the full amount without regard to the FDIC shared-loss agreement, and the portion of the loss reimbursable from the FDIC is recorded in noninterest income and increases the FDIC indemnification asset.
	The purchased other loans not accounted for under FASB ASC 310-30 and the balances funded on purchased loans after the acquisition date, called “subsequent advances”, are also subject to the Company’s credit reviews. An allowance for loan loss is estimated in a similar manner as the originated loan portfolio, and a provision for loan loss is charged to earnings as necessary. Management also reviews historical and environmental factors specific to the purchased portfolios which may be slightly different than the originated loan portfolio.
	FDIC Indemnification Asset
	The FDIC indemnification asset was measured at estimated fair value at acquisition date on the same basis as the purchased covered loans, and represents the present value of the estimated losses on covered loans to be reimbursed by the FDIC. The present value was calculated using the shorter of the shared-loss agreement terms or the life of the loan. Under the terms of the FDIC shared-loss agreements, the FDIC will absorb 80% of losses and receive 80% of loss recoveries for the covered loans. The FDIC indemnification asset will be reduced as losses are recognized on covered loans and shared-loss payments are received from the FDIC. Since the FDIC indemnification asset was initially recorded at estimated fair value using a discount rate, a portion of the discount is taken into noninterest income at each reporting date.
	The FDIC indemnification asset is evaluated quarterly. Realized losses in excess of prior estimates will immediately increase the FDIC indemnification asset by a credit to noninterest income. Conversely, if realized losses are less than prior estimates, the FDIC indemnification asset will be reduced by a charge to noninterest income on a prospective basis, and any change in value would be limited to the contractual terms of the shared-loss agreement.
	Mortgage Banking Operations
	Until the second quarter of 2013, the Company sold one-to-four family residential mortgage loans on a servicing released basis and recognized a cash gain or loss. A cash gain or loss was recognized to the extent that the sales proceeds of the mortgage loans sold exceeded or were less than the net book value at the time of sale. Income from mortgage loans brokered to other lenders was recognized into income on date of loan closing.
	Commitments to sell one-to-four family residential mortgage loans were made primarily during the period between the taking of the loan application and the closing of the mortgage loan. The timing of making these sale commitments was dependent upon the timing of the borrower’s election to lock-in the mortgage interest rate and fees prior to loan closing. Most of these sale commitments were made on a best-efforts basis whereby the Bank was only obligated to sell the mortgage if the mortgage loan was approved and closed by the Bank. Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans were accounted for as free standing derivatives. Fair values of these mortgage derivatives were estimated based on changes in mortgage interest rates from the date the interest on the loan was locked. The Company entered into forward commitments for the future delivery of mortgage loans when interest rate locks were entered into, in order to hedge the change in interest rates resulting from its commitments to fund the loans. Changes in the fair values of these derivatives were included in gains on sales of loans. As there were no loans held for sale at December 31, 2013, there was no associated derivative. The fair value of these derivative instruments was not significant at December 31, 2012 and 2011.
	Other Real Estate and Other Assets Owned
	Other real estate acquired by the Company in satisfaction of debt are held for sale and recorded at fair value at time of foreclosure. When property is acquired, it is recorded at the estimated fair value (less the costs to sell) at the date of acquisition, not to exceed net realizable value, and any resulting write-down is charged to the allowance for loan losses. Upon acquisition, all costs incurred in maintaining the property are expensed. Costs relating to the development and improvement of the property, however, are capitalized to the extent of the property’s net realizable value.
Premises and Equipment
Premises and equipment, including leasehold improvements, are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets or the lease period, whichever is shorter. The estimated useful lives used to compute depreciation and amortization for buildings and building improvements is 15 to 39 years; and for furniture, fixtures and equipment is three to seven years. The Company reviews buildings, leasehold improvements and equipment for impairment whenever events or changes in the circumstances indicate that the undiscounted cash flows for the property are less than its carrying value. If identified, an impairment loss is recognized through a charge to earnings based on the fair value of the property.
Other Intangible Assets
The other intangible assets represents the Core Deposit Intangible (“CDI”) acquired in business combinations. The fair value of the CDI stemming from any given business combination is based on the present value of the expected cost savings attributable to the core deposit funding, relative to an alternative source of funding. The CDI is amortized over an estimated useful life which approximates the existing deposit relationships acquired on an accelerated method. The Company evaluates such identifiable intangibles for impairment when an indication of impairment exists.
Goodwill
The Company’s goodwill represents the excess of the purchase price over the fair value of net assets acquired in the purchases of Valley Community Bancshares in 2013, Western Washington Bancorp in 2006 and North Pacific Bank in 1998. The Company’s goodwill is assigned to Heritage Bank and is evaluated for impairment at the Heritage Bank level (reporting unit).
In accordance with Accounting Standards Update ("ASU") 2011-08 Intangibles – Goodwill and Other (Topic 350), an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. In other words, before the first step of the existing guidance, the entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that the fair value of goodwill is less than carrying value. The qualitative assessment includes adverse events or circumstances identified that could negatively affect the reporting units’ fair value as well as positive and mitigating events. Such indicators may include, among others: a significant change in legal factors or in the general business climate; significant change in the Company’s stock price and market capitalization; unanticipated competition; and an action or assessment by a regulator. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step process is unnecessary. The entity has the option to bypass the qualitative assessment step for any reporting unit in any period and proceed directly to the first step of the exiting two-step process. The entity can resume performing the qualitative assessment in any subsequent period.
The first step of the goodwill impairment test is performed, when considered necessary, by comparing the reporting unit’s aggregate fair value to its carrying value. Absent other indicators of impairment, if the aggregate fair value exceeds the carrying value, goodwill is not considered impaired and no additional analysis is necessary. If the carrying value of the reporting unit were to exceed the aggregate fair value, a second step would be performed to measure the amount of impairment loss, if any. To measure any impairment loss the implied fair value would be determined in the same manner as if the reporting unit were being acquired in a business combination. If the implied fair value of goodwill is less than the recorded goodwill, an impairment charge would be recorded for the difference.
Income Taxes
The Company and its subsidiary file a United States consolidated federal income tax return and an Oregon State income tax return. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates applicable to taxable income in the periods in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in income in the period that includes the enactment date.
The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in “income taxes” in the Consolidated Statements of Income as the amounts are generally insignificant each year.
Employee Stock Ownership Plan
The Company sponsored an Employee Stock Ownership Plan (ESOP). The ESOP purchased 2% of the common stock issued in a January 1998 stock offering and borrowed $1.3 million from the Company in order to fund the purchase of the Company’s common stock. The loan to the ESOP was repaid in full as of December 31, 2012. When outstanding, the loan was repaid principally from the Bank's contributions to the ESOP. The Bank's contributions were sufficient to service the debt over the 15-year loan term at the interest rate of 8.5%. As the debt was repaid, shares were released and allocated to plan participants based on the proportion of debt service paid during the year. As shares were released, compensation expense was recorded equal to the then current market price of the shares and the shares became outstanding for earnings per common share calculations. Cash dividends on allocated shares were recorded as a reduction of retained earnings and paid or distributed directly to participants’ accounts. Cash dividends on unallocated shares were recorded as a reduction of debt and accrued interest.
Stock-Based Compensation
The Company maintains a number of stock-based incentive programs, which are discussed in more detail in Note 15, "Stock-Based Compensation." Compensation cost is recognized for stock options and restricted stock awards issued to employees and directors, based on the fair value of these awards at the date of grant. The Company did not grant stock option awards for the years ended December 31, 2013, 2012 or 2011. The fair value of stock options granted would be estimated on the date of grant using the Black-Scholes-Merton option pricing model. The market price of the Company’s common stock at the date of grant is used for the restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period, on a straight-line basis.
Deferred Compensation Plans
The Company has adopted a Deferred Compensation Plan and has entered into arrangements with certain executive officers. Under the Plan, participants are permitted to elect to defer compensation and the Company has the discretion to make additional contributions to the Plan on behalf of any participant based on a number of factors. Such discretionary contributions are generally approved by the Compensation Committee of the Company's Board of Directors. The notional account balances of participants under the Plan earn interest on an annual basis. The applicable interest rate is the Moody’s Seasoned Aaa Corporate Bond Yield as of January 1 of each year. Generally, a participant’s account is payable upon the earliest of the participant’s separation from service with the Company, the participant’s death or disability, or a specified date that is elected by the participant in accordance with applicable rules of the Internal Revenue Code. The Company’s obligation to make payments under the Plan is a general obligation of the Company and is to be paid from the Company’s general assets. As such, participants are general unsecured creditors of the Company with respect to their participation under the Plan. The Company records a liability within accrued expenses and other liabilities on the Consolidated Statements of Financial Condition in a systematic and rationale manner. Since the amounts earned are generally based on the Company’s annual performance, the Company records deferred compensation expense each year for an amount calculated based on that year’s financial performance.
Earnings per Share
Basic earnings per common share is net income available to common shareholders divided by the weighted average number of common shares outstanding during the period. ESOP shares are considered outstanding for this calculation unless unearned. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options. Earnings and dividends per share are restated for all stock splits and stock dividends through the date of issuance of the financial statements.
Operating Segments
While the Company’s chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
(d) Recently Issued Accounting Pronouncements
FASB ASU 2011-11, Disclosures about Offsetting Assets and Liabilities, was issued in December 2011 to require an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. The adoption of the Update did not have a material effect on the Company’s Consolidated Financial Statements at the date of its adoption.
FASB ASU 2012-6, Business Combinations (Topic 805): Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution, was issued in October 2012. The objective of the Update was to address the diversity in practice about how to interpret the terms “on the same basis” and “contractual limitations” when subsequently measuring an indemnification asset. This Update was effective for fiscal years and interim periods beginning on or after December 15, 2012. Early adoption was permitted, and adoption was to be applied prospectively to indemnification assets existing as of the date of adoption. The adoption of this Update did not have a material effect on the Company’s Consolidated Financial Statements at the date of adoption as the Company previously accounted for its indemnification asset in a manner consistent with the Update.
FASB ASU 2013-2, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, was issued in February 2013. The Update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income (loss) by component and to present either on the face of the statement where net income is presented, or in the notes, significant amounts reclassified out of accumulated other comprehensive income (loss) by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. The amendments became effective for annual and interim reporting periods beginning on or after December 15, 2012. The adoption of this Update did not have a material effect on the Company’s Consolidated Financial Statements. The additional disclosures are included in Note 18, “Accumulated Other Comprehensive (Loss) Income.”
FASB ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, A Similar Tax Loss, or a Tax Credit Carryforward Exists, was issued in July 2013. This Update provides that an unrecognized tax benefit, or a portion thereof, be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent that a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented as a liability. These amendments are effective for interim and annual reporting periods beginning after December 15, 2013. Early adoption and retrospective application is permitted. The Company is currently evaluating the impact of this amendment on the Consolidated Financial Statements.

	During the year ended December 31, 2013, the Company completed the acquisitions of Northwest Commercial Bank and Valley Community Bancshares, referred to jointly as the "NCB and Valley Acquisitions." There were no acquisitions completed during the years ended December 31, 2012 and 2011.
	Northwest Commercial Bank
	On September 14, 2012, the Company and Heritage Bank entered into a definitive agreement to acquire NCB headquartered in Lakewood, Washington. NCB was a full service commercial bank that operated two branch locations in Lakewood and Auburn, Washington. Prior to the closing of the transaction, NCB redeemed its outstanding preferred stock of approximately $2.0 million issued to the U.S. Department of Treasury in connection with its participation in the Troubled Asset Relief Program Capital Purchase Plan. The NCB Acquisition was completed on January 9, 2013 with the merger of NCB with and into Heritage Bank. After the NCB Acquisition, the NCB Lakewood branch was consolidated into one of Heritage Bank’s full service banking offices in Lakewood, Washington.
	In connection with the NCB Acquisition, the Company paid cash consideration of $3.0 million, or $5.50 per NCB share, to NCB shareholders on January 9, 2013. In addition, pursuant to the merger agreement, the NCB shareholders had the ability to potentially receive an additional cash payment based on an earn-out structure from the sale of a NCB asset included in “other real estate owned.” This contingent payment was factored into the NCB liabilities assumed by Heritage Bank as of the January 9, 2013 acquisition date. This asset was sold by Heritage Bank in June 2013, and the $491,000 of proceeds from the sale were paid to the NCB shareholders in July 2013. The payment of these proceeds did not impact the recorded bargain purchase gain on bank acquisition of $399,000.
	During the years ended December 31, 2013 and 2012, the Company incurred NCB Acquisition-related costs (including conversion costs) of approximately $794,000 and $616,000, respectively.
	Valley Community Bancshares
	On March 11, 2013, the Company entered into a definitive agreement to acquire Valley Community Bancshares and its wholly-owned subsidiary, Valley Bank, both headquartered in Puyallup, Washington. The Valley Acquisition was completed on July 15, 2013. Valley operated eight branches prior to acquisition, of which only four were maintained by Heritage Bank. Of the four other branches, three leases were terminated during the fourth quarter of 2013 and one owned branch building was considered held for sale at the time of acquisition.
	Pursuant to the terms of the merger agreement, the shareholders of Valley common stock received $19.50 per share in cash and 1.3611 shares of Heritage common stock per Valley share. The merger consideration for Valley consisted of cash and stock, with $22.0 million paid in cash by the Company and 1,533,267 shares of the Company’s common stock being issued with fair value of $24.2 million. The Company also recognized $157,000 in capitalized acquisition costs related to the issuance of its securities.
	The Valley Acquisition resulted in $16.4 million of goodwill. This goodwill is not deductible for tax purposes.
	During the year ended December 31, 2013, the Company incurred Valley Acquisition-related costs (including conversion costs) of approximately $2.1 million.
	Business Combination Accounting
	The NCB and Valley Acquisitions constitute business acquisitions as defined by FASB ASC 805, Business Combinations. FASB ASC 805 establishes principles and requirements for how the acquirer of a business recognizes and measures in its financial statements the identifiable assets acquired and the liabilities assumed. Accordingly, the estimated fair values of the acquired assets, including the identifiable intangible assets, and the assumed liabilities in the acquisition were measured and recorded as of the acquisition dates.
	The fair value of the assets acquired and liabilities assumed in the NCB and Valley Acquisitions were as follows:
		Valley			NCB

	Net assets acquired	$	29,969		$	3,366
	Summaries of the net assets purchased and the estimated fair value adjustments and resulting bargain purchase gain or goodwill recognized from the NCB and Valley Acquisitions were as follows:

	Accrued expenses and other liabilities	149			(622		)
	(Goodwill) bargain purchase gain recognized from the acquisition	$	(16,353	)	$	399
	Goodwill on bank acquisition represents the excess of the consideration transferred over the estimated fair value of the net assets acquired and liabilities assumed. A bargain purchase gain on bank acquisition represents the excess of the estimated fair value of the net assets acquired and liabilities assumed over the value of the consideration paid. The bargain purchase gain in the NCB Acquisition was influenced significantly by the net deferred tax asset acquired. NCB had significant net operating losses and as a result of its estimate of whether or not it was more likely than not that the net deferred tax asset would be realized, had recorded a full valuation allowance on the net deferred tax asset. The Company, however, has reviewed the net deferred tax asset and determined it is more likely than not that the net deferred tax asset would be realized by the Company.
	The operating results of the Company for the year ended December 31, 2013 include the operating results produced by the net assets acquired from the NCB Acquisition since the January 9, 2013 acquisition date and from the Valley Acquisition since the July 15, 2013 acquisition date. The Company has considered the requirement of FASB ASC 805 related to the contribution of the NCB and Valley Acquisitions to the Company’s results of operations. The table below presents only the significant results for the acquired businesses from the acquisition dates.

-3	The NCB Acquisition was completed on January 9, 2013 and the Valley Acquisition was completed on July 15, 2013.
The Company also considered the pro forma requirements of FASB ASC 805 and deemed it not necessary to provide pro forma financial statements as required under the standard as the NCB and Valley Acquisitions were not material to the Company. The Company believes that the historical NCB and Valley operating results are not considered of enough significance to be meaningful to the Company’s results of operations.

The Company has evaluated these securities and has determined that, other than certain private residential collateralized mortgage obligations discussed below, the decline in their value is temporary. The unrealized losses are primarily due to increases in market interest rates and larger spreads in the market for mortgage-related products. The fair value of these securities is expected to recover as the securities approach their maturity date and/or as the pricing spreads narrow on mortgage-related securities. The Company has the ability and intent to hold the investments until recovery of the market value which may be the maturity date of the securities.
To analyze the unrealized losses, the Company estimated expected future cash flows of the private residential collateralized mortgage obligations by estimating the expected future cash flows of the underlying collateral and applying those collateral cash flows, together with any credit enhancements such as subordination interests owned by third parties, to the security. The expected future cash flows of the underlying collateral are determined using the remaining contractual cash flows adjusted for future expected credit losses (which considers current delinquencies and nonperforming assets, future expected default rates and collateral value by vintage and geographic region) and prepayments. The expected cash flows of the security are then discounted at the interest rate used to recognize interest income on the security to arrive at a present value amount. The average discount interest rates used in the valuations of the present value as of December 31, 2013 and 2012 were 6.4% and 7.2%, respectively, and the average prepayment rate for each period was 6.0%.
For the year ended December 31, 2013, there were eight private residential collateralized mortgage obligations determined to be other-than-temporarily impaired. All unrealized losses for the year ended December 31, 2013 were deemed to be credit related, and the Company recorded the impairment in earnings. For the year ended December 31, 2012, there were eight private residential collateralized mortgage obligations determined to be other-than-temporarily impaired. The portion of the impairment for the year ended December 31, 2012 and 2011 that was credit related was recorded in earnings and the portion of the impairment not related to credit losses was recorded through other comprehensive (loss) income. The following table summarizes activity for the years ended December 31, 2013, 2012 and 2011 related to the amount of impairments on held to maturity securities:

(c) Redemption-in-Kind
In May 2008, the Board of Trustees of the AMF Ultra Short Mortgage Fund (“Fund”) decided to activate the Fund’s redemption-in-kind provision because of the uncertainty in the mortgage backed securities market. Exiting participants in the Fund were allowed to redeem and receive up to $250,000 in cash per quarter or receive 100% of their investment in “like-kind” securities equal to their proportional ownership in the Fund. The Company elected to receive the like-kind securities.
Details of private residential collateralized mortgage obligation securities received from the redemption-in-kind election as of December 31, 2013 were as follows:

Loans and Leases Receivable Disclosure [Abstract]	'
Loans Receivable	'
	Loans Receivable
	The Company originates loans in the ordinary course of business. These loans are identified as “originated” loans. Disclosures related to the Company’s recorded investment in originated loans receivable generally exclude accrued interest receivable and net deferred loan origination fees and costs because they are insignificant. The Company has also acquired loans through FDIC-assisted and open bank transactions. Loans acquired in a business acquisition are designated as “purchased” loans. The Company refers to the purchased loans subject to the FDIC shared-loss agreements as “covered” loans, and those loans without shared-loss agreements are referred to as “non-covered” loans. Loans purchased with evidence of credit deterioration since origination for which it is probable that not all contractually required payments will be collected are accounted for under FASB ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. These loans are identified as “purchased impaired” loans. Loans purchased that are not accounted for under FASB ASC 310-30 are accounted for under FASB ASC 310-20, Receivables—Nonrefundable Fees and Other Costs. These loans are identified as “purchased other” loans.
	(a) Loan Origination/Risk Management
	The Company originates loans in one of the four segments of the total loan portfolio: commercial business, real estate construction and land development, one-to-four family residential and consumer. Within these segments are classes of loans to which management monitors and assesses credit risk in the loan portfolios. The Company has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies, and nonperforming and potential problem loans. The Company also conducts internal loan reviews and validates the credit risk assessment on a periodic basis and presents the results of these reviews to management. The loan review process complements and reinforces the risk identification and assessment decisions made by loan officers and credit personnel, as well as the Company’s policies and procedures.
	A discussion of the risk characteristics of each loan portfolio segment is as follows:
	Commercial Business:
	There are three significant classes of loans in the commercial portfolio segment, including commercial and industrial loans, owner-occupied commercial real estate and non-owner occupied commercial real estate. The owner and non-owner occupied commercial real estate are both considered commercial real estate loans. As the commercial and industrial loans carry different risk characteristics than the commercial real estate loans, they are discussed separately below.
	Commercial and industrial. Commercial and industrial loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial and industrial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may include a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers.
	Commercial real estate. The Company originates commercial real estate loans within its primary market areas. These loans are subject to underwriting standards and processes similar to commercial and industrial loans, in addition to those of real estate loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate involves more risk than other classes of loans in that the lending typically involves higher loan principal amounts, and payments on loans secured by real estate properties are dependent on successful operation and management of the properties. Repayment of these loans may be more adversely affected by conditions in the real estate market or the economy.
	One-to-Four Family Residential:
	The majority of the Company’s one-to-four family residential loans are secured by single-family residences located in its primary market areas. The Company’s underwriting standards require that single-family portfolio loans generally are owner-occupied and do not exceed 80% of the lower of appraised value at origination or cost of the underlying collateral. Terms of maturity typically range from 15 to 30 years. Until second quarter 2013, the Company sold most single-family loans in the secondary market and retained a smaller portion in its loan portfolio. After the second quarter of 2013, the Company only originated single-family loans for its loan portfolio.
	Real Estate Construction and Land Development:
	The Company originates construction loans for one-to-four family residential and for five or more family residential and commercial properties. The one-to-four family residential construction loans generally include construction of custom homes whereby the home buyer is the borrower. The Company also provides financing to builders for the construction of pre-sold homes and, in selected cases, to builders for the construction of speculative residential property. Substantially all construction loans are short-term in nature and priced with variable rates of interest. Construction lending can involve a higher level of risk than other types of lending because funds are advanced partially based upon the value of the project, which is uncertain prior to the project’s completion. Because of the uncertainties inherent in estimating construction costs as well as the market value of a completed project and the effects of governmental regulation of real property, the Company’s estimates with regards to the total funds required to complete a project and the related loan-to-value ratio may vary from actual results. As a result, construction loans often involve the disbursement of substantial funds with repayment dependent, in part, on the success of the ultimate project and the ability of the borrower to sell or lease the property or refinance the indebtedness. If the Company’s estimate of the value of a project at completion proves to be overstated, it may have inadequate security for repayment of the loan and may incur a loss if the borrower does not repay the loan. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to successful completion of the construction project, interest rate changes, governmental regulation of real property, general economic conditions and the availability of long-term financing.
	Consumer:
	The Company originates consumer loans and lines of credit that are both secured and unsecured. The underwriting process for these loans ensures a qualifying primary and secondary source of repayment. Underwriting standards for home equity loans are significantly influenced by statutory requirements, which include, but are not limited to, a maximum loan-to-value percentage of 80%, collection remedies, the number of such loans a borrower can have at one time and documentation requirements. To monitor and manage consumer loan risk, policies and procedures are developed and modified, as needed. The majority of consumer loans are for relatively small amounts disbursed among many individual borrowers which reduces the credit risk for this type of loan. To further reduce the risk, trend reports are reviewed by management on a regular basis.

(b) Concentrations of Credit
Most of the Company’s lending activity occurs within Washington State, and to a lesser extent Oregon State. The Company’s primary market areas include Thurston, Pierce, King, Mason, Cowlitz, Yakima, Kittitas and Clark counties in Washington and Multnomah County in Oregon, as well as other contiguous markets. The majority of the Company’s loan portfolio consists of (in order of balances at December 31, 2013) non-owner occupied commercial real estate, commercial and industrial and owner-occupied commercial real estate. As of December 31, 2013 and December 31, 2012, there were no concentrations of loans related to any single industry in excess of 10% of the Company’s total loans.
(c) Credit Quality Indicators
As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related to (i) the risk grade of the loans, (ii) the level of classified loans, (iii) net charge-offs, (iv) nonperforming loans, and (v) the general economic conditions of the United States of America, and specifically the states of Washington and Oregon. The Company utilizes a risk grading matrix to assign a risk grade to each of its loans. Loans are graded on a scale of 0 to 9, and a “W.” A description of the general characteristics of the risk grades is as follows:
•	Grades 0 to 5: These grades are considered “pass grade” and includes loans with negligible to above average but acceptable risk. These borrowers generally have strong to acceptable capital levels and consistent earnings and debt service capacity. Loans with the higher grades within the “pass” category may include borrowers who are experiencing unusual operating difficulties, but have acceptable payment performance to date. Increased monitoring of financials and/or collateral may be appropriate. Loans with this grade show no immediate loss exposure.
•	Grade “W”: This grade is considered “pass grade” and includes loans on management’s “watch list” and is intended to be utilized on a temporary basis for pass grade borrowers where a potentially significant risk-modifying action is anticipated in the near term.
•	Grade 6: This grade includes “Other Assets Especially Mentioned” (“OAEM”) loans in accordance with regulatory guidelines, and is intended to highlight loans with elevated risks. Loans with this grade show signs of deteriorating profits and capital, and the borrower might not be strong enough to sustain a major setback. The borrower is typically higher than normally leveraged, and outside support might be modest and likely illiquid. The loan is at risk of further decline unless active measures are taken to correct the situation.
•	Grade 7: This grade includes “Substandard” loans in accordance with regulatory guidelines, for which the Company has determined have a high credit risk. These loans also have well-defined weaknesses which make payment default or principal exposure likely, but not yet certain. The borrower may have shown serious negative trends in financial ratios and performance. Such loans may be dependent upon collateral liquidation, a secondary source of repayment or an event outside of the normal course of business. Loans with this grade can be placed on accrual or nonaccrual status based on the Company’s accrual policy.
•	Grade 8: This grade includes “Doubtful” loans in accordance with regulatory guidelines, and the Company has determined these loans to have excessive credit risk. Such loans are placed on nonaccrual status and may be dependent upon collateral having a value that is difficult to determine or upon some near-term event which lacks certainty. Additionally, these loans generally have a specific valuation allowance.
•	Grade 9: This grade includes “Loss” loans in accordance with regulatory guidelines, and the Company has determined these loans have the highest risk of loss. Such loans are charged-off or charged-down when payment is acknowledged to be uncertain or when the timing or value of payments cannot be determined. “Loss” is not intended to imply that the loan or some portion of it will never be paid, nor does it in any way imply that there has been a forgiveness of debt.
Loan grades for all commercial business loans and real estate construction and land development loans are established at the origination of the loan. One-to-four family residential loans and consumer loans (“non-commercial loans”) are not graded with a 0 to 9 at origination date as these loans are determined to be “pass graded” loans. These non-commercial loans may subsequently require a 0-9 risk grade if the credit department has evaluated the credit and determined it necessary to classify the loan. Loan grades are reviewed on a quarterly basis, or more frequently if necessary, by the credit department. Typically, an individual loan grade will not be changed from the prior period unless there is a specific indication of credit deterioration or improvement. Credit deterioration is evidenced by delinquency, direct communications with the borrower, or other borrower information that becomes known to management. Credit improvements are evidenced by known facts regarding the borrower or the collateral property.
The loan grades relate to the likelihood of losses in that the higher the grade, the greater the loss potential. Loans with a pass grade may have some inherent losses in the portfolios, but to a lesser extent than the other loan grades. These pass graded loans may also have a zero percent loss based on historical experience and current market trends. The OAEM loan grade is transitory in that the Company is waiting on additional information to determine the likelihood and extent of the potential loss. The likelihood of loss for OAEM graded loans, however, is greater than Watch graded loans because there has been measurable credit deterioration. Loans with a Substandard grade are generally loans for which the Company has individually analyzed for potential impairment. For Doubtful and Loss graded loans, the Company is almost certain of the losses, and the unpaid principal balances are generally charged-off to the realizable value.

(g) Troubled Debt Restructured Loans
A troubled debt restructured loan is a restructuring in which the Bank, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider. TDRs are considered impaired and are separately measured for impairment under FASB ASC 310-10-35, whether on accrual or nonaccrual status.
The recorded investment balance and related allowance for loan losses of accruing and non-accruing TDRs as of December 31, 2013 and December 31, 2012 were as follows:
	December 31, 2013								December 31, 2012
	Accruing				Non-Accruing				Accruing				Non-Accruing
	TDRs				TDRs				TDRs				TDRs

Allowance for loan losses on originated TDRs	2,187				133				2,131				1,994
Purchased other TDRs	5,903				110				1,437				7
Allowance for loan losses on purchased other TDRs	1,430				57				76				2
The unfunded commitment to borrowers related to originated TDRs was $1.5 million at both December 31, 2013 and December 31, 2012. There were $17,000 and $0 unfunded commitments to borrowers related to the purchased other TDRs as of December 31, 2013 and December 31, 2012, respectively.
Originated loans that were modified as TDRs during the years ended December 31, 2013 and 2012 are set forth in the following table:

-1	Number of contracts and outstanding principal balance represent loans which have balances as of year end as certain loans may have been paid-down or charged-off during the years ended December 31, 2013 and 2012.
-2	Includes subsequent payments after modifications and reflects the balance as of the end of the year. As the Bank did not forgive any principal or interest balance as part of the loan modification, the Bank’s recorded investment in each loan at the date of modification (pre-modification) did not change as a result of the modification (post-modification), except when the modification was the initial advance on a one-to-four family residential real estate construction and land development loan under a master guidance line. During the year ended December 31, 2013, the Company's initial advance at the time of modification on these construction loans totaled $1.1 million and the total commitment amount was $4.3 million. There were no construction loans under a master guidance line that were modified as TDRS during the year ended December 31, 2012.
A significant portion of the loans modified during the year ended December 31, 2013 (24 loans totaling $3.4 million at December 31, 2013) relate to a speculative construction home builder. As the builder completes and sells the units, the Bank will advance funds for the construction of another unit. The builder's loans for each separate unit were considered troubled debt restructured loans during the second quarter of 2013. Two of this borrower's 24 loans outstanding as of December 31, 2013 totaling $865,000 were nonaccrual. The related specific valuation allowance on this relationship is approximately $211,000 at December 31, 2013. The Bank closely monitors the activity of this borrower for potential losses.
Of the 59 loans modified during the year ended December 31, 2013, twelve loans with a total outstanding principal balance of $5.1 million were previously reported as TDRs as of December 31, 2012. Of the 34 loans modified during the year ended December 31, 2012, nine loans with a total outstanding principal balance of $2.4 million were previously reported as TDRs as of December 31, 2011. The Bank typically grants shorter extension periods to continually monitor the troubled credits despite the fact that the extended date might not be the date the Bank expects the cash flow. The Company does not consider these modifications a subsequent default of a TDR as new loan terms, specifically maturity dates, were granted. The potential losses related to these loans would have been considered in the period the loan was first reported as a TDR and adjusted, as necessary, in the current periods based on more recent information. The related specific valuation allowance for TDRs that were modified during the year ended December 31, 2013 was $1.4 million at December 31, 2013. The related specific valuation allowance for those TDRs that were previously reported as TDRs as of December 31, 2012 was $111,000 and the general allowance for loan losses for TDRs that were modified during the year ended December 31, 2013 that were not previously reported as TDRs was $274,000 as of December 31, 2012.
Purchased other loans that were modified as TDRs during the years ended December 31, 2013 and 2012 are set forth in the following table:

-1	Number of contracts and outstanding principal balance represent loans which have balances as of year end as certain loans may have been paid-down or charged-off during the years ended December 31, 2013 and 2012.
-2	Includes subsequent payments after modifications and reflects the balance as of the end of the year. The Bank’s initial recorded investment in each loan at the date of modification (pre-modification) did not change as a result of the modification (post-modification) as the Bank did not forgive any principal or interest balance as part of the loan modification.
The majority of the Bank’s TDRs are a result of granting extensions to troubled credits which have already been adversely classified. We grant such extensions to reassess the borrower’s financial status and to develop a plan for repayment. Certain modifications with extensions also include interest rate reductions, which is the second most prevalent concession. Certain TDRs were additionally re-amortized over a longer period of time. The Bank additionally advanced funds to a troubled speculative home builder to complete established projects as mentioned above. These modifications would all be considered a concession for a borrower that could not obtain similar financing terms from another source other than from the Bank.
The financial effects of each modification will vary based on the specific restructure. For the majority of the Bank’s TDRs, the loans were interest-only with a balloon payment at maturity. If the interest rate is not adjusted and the modified terms are consistent with other similar credits being offered, the Bank may not experience any loss associated with the restructure. If, however, the restructure involves forbearance agreements or interest rate modifications, the Bank may not collect all the principal and interest based on the original contractual terms. The Bank estimates the necessary allowance for loan losses on TDRs using the same guidance as used for other impaired loans.
There were three originated commercial and industrial TDRs with a principal balance totaling $918,000 that had been modified during the previous twelve months ended that subsequently defaulted during the year ended December 31, 2013. Two of these loans defaulted because they were past their modified maturity date while one defaulted due to a payment being past due 90 days or more. The Bank recorded a $63,000 related specific valuation allowance for these defaulted TDRs as of December 31, 2013.
There were no originated TDRs that had been modified during the previous twelve months ended that subsequently defaulted during the year ended December 31, 2012. There were no purchased other TDRs that had been modified during the previous twelve months ended that subsequently defaulted during the years ended December 31, 2013 and 2012.
(h) Purchased Impaired Loans
As indicated above, the Company purchased impaired loans from the Cowlitz, Pierce, NCB and Valley Acquisitions which are accounted for under FASB ASC 310-30.
The following tables reflect the outstanding balance at December 31, 2013 and December 31, 2012 of the purchased impaired loans by acquisition:

The total balance of subsequent advances on the purchased impaired covered loans was $2.6 million and $3.8 million as of December 31, 2013 and December 31, 2012, respectively. The Bank has the option to modify certain purchased covered loans which may terminate the FDIC shared-loss coverage on those modified loans. At both December 31, 2013 and December 31, 2012, the recorded investment balance of purchased impaired covered loans which are no longer covered under the FDIC shared-loss agreements was $1.7 million. The Bank continues to report these loans in the covered portfolio as they are in a pool and they continue to be accounted for under FASB ASC 310-30. The FDIC indemnification asset has been adjusted to reflect the change in the loan status.

-1	The NCB Acquisition was completed on January 9, 2013 and the Valley Acquisition was completed on July 15, 2013.
On the acquisition dates, the amount by which the undiscounted expected cash flows of the purchased impaired loans exceeded the estimate fair value of the loan is the “accretable yield”. The accretable yield is then measured at each financial reporting date and represents the difference between the remaining undiscounted expected cash flows and the current carrying value of the purchased impaired loan.
The following tables summarize the accretable yield on the purchased impaired loans resulting from the Cowlitz, Pierce, NCB and Valley Acquisitions for the years ended December 31, 2013 and 2012. As the NCB and Valley Acquisitions were completed in 2013, there are no balances for the years ended December 31, 2012 or 2011.

-1	For the NCB Acquisition, the contractual cash flows were $8.5 million and the expected cash flows were $5.6 million, resulting in a non-accretable difference of $2.9 million. As the fair value of these purchased impaired loans at the January 9, 2013 NCB Acquisition date was $4.9 million, this provides an accretable yield of $745,000, which the Company included in the change in accretable yield in the quarter of acquisition.
-2	For the Valley Acquisition, the contractual cash flows were $5.1 million and the expected cash flows were $4.4 million, resulting in a non-accretable difference of $692,000. As the fair value of these purchased impaired loans at the July 15, 2013 Valley Acquisition date was $4.1 million, this provides an accretable yield of $271,000, which the Company included in the change in accretable yield in the quarter of acquisition.

	The purchased loans acquired in the Cowlitz, Pierce, NCB and Valley Acquisitions are subject to the Company’s internal credit review. If and when credit deterioration occurs subsequent to the acquisition dates, a provision for loan losses will be charged to earnings for the full amount without regard to the FDIC shared-loss agreements for the covered loan balances. The portion of the estimated loss reimbursable from the FDIC is recorded in noninterest income and increases the FDIC indemnification asset.

	Goodwill and Other Intangible Assets
	(a) Goodwill
	The Company’s goodwill represents the excess of the purchase price over the fair value of net assets acquired in the purchases of Valley Community Bancshares, Inc. on July 15, 2013, Western Washington Bancorp in 2006 and North Pacific Bank in 1998. The Company’s goodwill is assigned to the Bank and is evaluated for impairment at the Bank level (reporting unit).
	The Company recorded$16.4 million of goodwill during the year ended December 31, 2013 due to the Valley Acquisition. There was no goodwill additions recorded during the year ended December 31, 2012.
	At December 31, 2013, the Company’s step-one analysis concluded that the reporting unit’s fair value was greater than its carrying value and therefore no goodwill impairment charges were required for the year ended December 31, 2013. The Company did not record goodwill impairment charges for the years ended December 31, 2013, 2012 or 2011. Even though there was no goodwill impairment at December 31, 2013, adverse events may impact the recoverability of goodwill and could result in a future impairment charge which could have a material impact on the Company’s Consolidated Financial Statements.
	b) Other Intangible Assets
	The other intangible assets represents the Core Deposit Intangible acquired in business combinations. The useful life of the CDI related to Valley Community Bancshares, Inc., Northwest Commercial Bank, Pierce Commercial Bank, Cowlitz Bank, and Western Washington Bancorp acquisitions is ten, five, four, nine, and eight years, respectively.
	During the year ended December 31, 2013, the Company recorded additions of intangible assets of $1.1 million due to the NCB and Valley Acquisitions. There were no intangible asset additions recorded during the year ended December 31, 2012.
	Amortization expense related to the core deposit intangibles was $543,000, $427,000 and $440,000 for the years ended December 31, 2013, 2012 and 2011.
	The estimated aggregated amortization expense related to these intangible assets for future years is as follows:

	Other Borrowings
	(a) FHLB Advances
	The Federal Home Loan Bank of Seattle functions as a member-owned cooperative providing credit for member financial institutions. Advances are made pursuant to several different programs. Each credit program has its own interest rate and range of maturities. Depending on the program, limitations on the amount of advances are based either on a fixed percentage of an institution’s net worth or on the FHLB’s assessment of the institution’s creditworthiness. At December 31, 2013, the Bank maintained a credit facility with the FHLB of Seattle for $283.6 million. During the years ended December 31, 2013 and 2012 there were no FHLB borrowing transactions completed and at December 31, 2013 and 2012 there were no FHLB advances outstanding.
	Advances from the FHLB are collateralized by a blanket pledge on FHLB stock owned by the Bank, deposits at the FHLB and all mortgages or deeds of trust securing such properties. In accordance with the pledge agreement, the Company must maintain unencumbered collateral in an amount equal to varying percentages ranging from 100% to 125% of outstanding advances depending on the type of collateral. At December 31, 2013, the Bank was not required to maintain collateral in order to meet the collateral requirements of the FHLB.
	(b) Federal Funds Purchased
	The Bank maintains advance lines to purchase federal funds totaling $50.0 million as of December 31, 2013. The lines generally mature annually or are reviewed annually. As of December 31, 2013 and 2012, there were no federal funds purchased.
	(c) Credit facilities
	The Bank maintains a credit facility with the Federal Reserve Bank of San Francisco for $56.7 million as of December 31, 2013, of which there were no borrowings outstanding as of December 31, 2013 or 2012. Any advances on the credit facility would have to be first pledged with the Bank's investment securities or loans.

	The Company has qualified under provisions of the Internal Revenue Code to compute income taxes after deductions of additions to the bad debt reserves. At December 31, 2013, the Company had a taxable temporary difference of approximately $2.8 million that arose before 1988 (base-year amount). In accordance with FASB ASC 740, a deferred tax liability of an estimated $980,000 has not been recognized for the temporary difference. Management does not expect this temporary difference to reverse in the foreseeable future.
	In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. A valuation allowance is required to be recognized for the portion of the deferred tax asset that will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management expects to realize the benefits of these deductible differences at December 31, 2013.
	The Company has a net operating loss carryforward of $1.7 million as of December 31, 2013 that will expire in 2033. The Company is limited to the amount of the net operating loss carryforward that it can deduct each year. The Company also has $270,000 of federal capital loss carryforwards as of December 31, 2013 which will expire in 2018. A tax planning strategy has been developed that will enable the Company to deduct all of the net operating loss and capital loss carryforwards prior to their respective expirations. Based on these estimates, management has not recorded a valuation allowance as of December 31, 2013. During the year ended December 31, 2013, management reversed the valuation allowance that was established in the prior year.
	As of December 31, 2013 and December 31, 2012, the Company had an insignificant amount of unrecognized tax benefits, none of which would materially affect its effective tax rate if recognized. The Company does not anticipate that the amount of unrecognized tax benefits will significantly increase or decrease in the next 12 months. The amount of interest and penalties accrued as of December 31, 2013 and 2012 and for the years ended December 31, 2013, 2012 and 2011 were immaterial.
	The Company and its subsidiary file a United States consolidated federal income tax return and an Oregon State income tax return, and the tax years subject to examination by the Internal Revenue Service are the years ended December 31, 2013, 2012, 2011 and 2010.

Stock-Based Compensation	'
	Stock-Based Compensation
	Stock options generally vest ratably over three years and expire five years after they become exercisable or vest ratably over four years and expire ten years from date of grant. Restricted stock awards issued generally have a five-year cliff vesting or four year ratable vesting schedule. The Company issues new shares to satisfy share option exercises and restricted stock awards. As of December 31, 2013, 110,436 shares remain available for future issuances under stock-based compensation plans.
	(a) Stock Option Awards
	For the years ended December 31, 2013, 2012 and 2011, the Company recognized compensation expense related to stock options of $71,000, $106,000 and $165,000, respectively, and a related tax benefit of $0, $1,000 and $6,000, respectively. As of December 31, 2013, the total unrecognized compensation expense related to non-vested stock options was $76,000 and the related weighted average period over which it is expected to be recognized is approximately 0.39 years. The intrinsic value and cash proceeds from options exercised during the year ended December 31, 2013 totaled $54,000 and $200,000, respectively. The intrinsic value and cash proceeds from options exercised during the year ended December 31, 2012 totaled $31,000 and $129,000, respectively.

	The Company measures the fair value of each stock option grant at the date of the grant using the Black-Scholes-Merton option pricing model. The expected term of share options is derived from historical data and represents the period of time that share options granted are expected to be outstanding. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for a bond with a maturity equal to the expected term. Expected volatility is based on historical volatility of Company shares over a period commensurate with the expected term. Expected dividend yield is based on dividends expected to be paid during the expected term of the share options. There were no options granted during the years ended December 31, 2013, 2012 or 2011.
	(b) Restricted and Unrestricted Stock Awards
	For the years ended December 31, 2013, 2012 and 2011, the Company recognized compensation expense related to restricted and unrestricted stock awards of $1.2 million, $1.1 million and $737,000, respectively, and a related tax benefit of $428,000, $367,000, and $258,000, respectively. As of December 31, 2013, the total unrecognized compensation expense related to non-vested restricted and unrestricted stock awards was $1.9 million and the related weighted average period over which it is expected to be recognized is approximately 2.17 years. The vesting date fair value of restricted stock awards that vested during the years ended December 31, 2013, 2012 and 2011 was $1.2 million, $842,000 and $396,000, respectively.

Employee Benefits and Share-based Compensation [Abstract]	'
Employee Benefit Plans	'
	Employee Benefit Plans
	(a) Employee Stock Ownership Plan
	Effective October 1, 1999 the Company combined three retirement plans, a money purchase pension plan, a 401(k) plan, and an employee stock ownership plan (ESOP) at Heritage Bank, and the 401(k) plan at Central Valley Bank into one plan called the Heritage Financial Corporation 401(k) Employee Stock Ownership Plan (“KSOP”). In 2010, the Company amended the KSOP to provide certain service credit for vesting and/or contribution purposes to employees of Cowlitz Bank and Pierce Commercial Bank at the time of each acquisition.
	The profit sharing portion of the KSOP is a defined contribution retirement plan. The plan provides a contribution to all eligible participants upon credit of 1,000 hours of service during the plan year, the attainment of 18 years of age, and employment on the last day of the year of 2% of the participants’ eligible compensation. The Company can also provide discretionary profit sharing contributions beyond the required 2% contribution. It is the Company’s policy to fund plan costs as accrued. Employee vesting in the profit sharing occurs over a period of six years, at which time they become fully vested. Employer profit sharing contributions were $600,000, $631,000 and $562,000 for the years ended December 31, 2013, 2012 and 2011, respectively.
	The KSOP also includes the Company’s salary savings 401(k) plan for its employees. All persons employed as of July 1, 1984 automatically participate in the plan. All employees hired after that date who are at least 18 years of age may participate in the plan the first of the month following thirty days of service. Employees who participate may contribute a portion of their salary, which is matched by the employer at 50% up to 6% of eligible compensation, up to certain Internal Revenue Service limits. Employee vesting in employer matching occurs over a period of 6 years for those contributions made after January 1, 2003. Employer matching contributions for the years ended December 31, 2013, 2012 and 2011 were $497,000, $444,000 and $438,000, respectively.
	The third portion of the KSOP is the employee stock ownership plan (ESOP). Heritage Bank established the ESOP and related trust for eligible employees effective July 1, 1994, which became active upon the former mutual holding company’s conversion to a stock-based holding company in January 1995. The ESOP provides a contribution to all eligible participants upon completion of one year of service, the attainment of 18 years of age, and employment on the last day of the year. Employee vesting occurs over a period of six years. The ESOP is funded by employer contributions in cash or common stock. During the year ended December 31, 2012, the loan related to the ESOP was paid in full; therefore, there is no ESOP compensation expense for the year ended December 31, 2013. ESOP compensation expense was $139,000 and $119,000 for the years ended December 31, 2012 and 2011, respectively. For the year ended December 31, 2013, the Company had no allocated or committed shares to be released to the ESOP and has no unearned, restricted shares remaining to be released as of December 31, 2013.
	(b) Employment Agreements
	The Company has entered into contracts with certain senior officers that provide benefits under certain conditions following termination without cause, and/or following a change of control of the Company.
	(c) Deferred Compensation Plan
	During 2012, the Company adopted a Deferred Compensation Plan, which provides its directors and select executive officers with the opportunity to defer current compensation. Under the Plan, participants are permitted to elect to defer compensation and the Company has the discretion to make additional contributions to the Plan on behalf of any participant based on a number of factors. Compensation expense under the Deferred Compensation Plan totaled $445,000 and $312,000 for the years ended December 31, 2013 and 2012, respectively. The Company’s contributions totaled $155,000 and $150,000 for the years ended December 31, 2013 and 2012, respectively.

	Total diluted weighted average common shares outstanding	15,487,715				15,094,789			15,497,426
	Potential dilutive shares are excluded from the computation of earnings per share if their effect is anti-dilutive. For the years ended December 31, 2013, 2012 and 2011, anti-dilutive shares outstanding related to options to acquire common stock totaled 163,863, 249,215 and 488,423, respectively, as the assumed proceeds from exercise price, tax benefits and future compensation was in excess of the market value.
	(b) Dividends
	The timing and amount of cash dividends paid on the Company's common stock depends on the Company’s earnings, capital requirements, financial condition and other relevant factors. Dividends on common stock from the Company depend substantially upon receipt of dividends from the Bank, which is the Company’s predominant sources of income. The following table summarizes the dividend activity for the years ended December 31, 2013 and 2012.
	Declared		Cash		Record Date		Paid Date
			Dividend per
			Share
	1-Feb-12		$0.06		10-Feb-12		24-Feb-12

	October 23, 2013		$0.08		November 5, 2013		November 15, 2013
	The FDIC and the Washington DFI have the authority under their supervisory powers to prohibit the payment of dividends by Heritage Bank to the Company. Additionally, current guidance from the Federal Reserve Board provides, among other things, that dividends per share on the Company’s common stock generally should not exceed earnings per share, measured over the previous four fiscal quarters. Current regulations allow the Company and its subsidiary bank to pay dividends on their common stock if the Company’s or the Bank’s regulatory capital would not be reduced below the statutory capital requirements set by the Federal Reserve Board and the FDIC.
	(c) Stock Repurchase Program
	The Company has had various stock repurchase programs since March 1999. On August 30, 2012, the Board of Directors approved the Company’s tenth stock repurchase plan, authorizing the repurchase of up to 5% of the Company’s outstanding shares of common stock, or approximately 757,000 shares. On August 30, 2011, the Board of Directors approved the Company's ninth stock repurchase plan, authorizing the repurchase of up to 5% of the Company's outstanding share of common stock, or approximately 782,000 shares over a period of twelve months.
	The following table provides total repurchased shares and average share prices under the applicable Plans and years:
		Years Ended December 31,
		2013			2012			Plan Total
	Ninth Plan
	Repurchased shares	—			389,627			590,832
	Stock repurchase average share price	$0			$13.45			$12.83
	Tenth Plan
	Repurchased shares	544,000			52,900			596,900
	Stock repurchase average share price	$15.88			$13.88			$15.70
	During the years ended December 31, 2013 and 2012, the Company repurchased 13,138 and 3,419 shares at an average price of $14.29 and $14.08 to pay withholding taxes on restricted stock that vested during the years ended December 31, 2013 and 2012, respectively.
	(d) Preferred Stock and Warrant
	On November 21, 2008, the Company completed a sale to the U.S. Department of the Treasury (“Treasury”) of 24,000 shares of the Company’s Fixed Rate Cumulative Perpetual Preferred Stock, Series A (“preferred shares”), for an aggregate purchase price of $24.0 million in cash, with a related warrant to purchase 276,074 shares of the Company’s common stock. On December 22, 2010, the Company redeemed the 24,000 preferred shares. The Company paid the Treasury a total of $24.1 million, consisting of $24.0 million of principal and $123,000 of accrued and unpaid dividends.
	Under the terms of the warrant, and because the Company’s September 2009 common stock issuance was a “qualified equity offering” resulting in aggregate gross proceeds of at least $24.0 million, the number of shares of the Company’s common stock underlying the warrant was reduced by 50% to 138,037 shares. On August 17, 2011, the Company repurchased the warrant from the Treasury for $450,000. The warrant repurchase, together with the Company’s earlier redemption of the entire amount of the preferred shares issued to the Treasury, represents full repayment of all TARP obligations and cancellation of all equity interests in the Company held by the Treasury.
	(e) Common Stock
	The acquisition of Valley Community Bancshares, Inc. was effective on July 15, 2013. In conjunction with this acquisition was the issuance of 1.53 million shares of the Company’s common stock at a fair value of $24.2 million.

Regulatory Capital Requirements	'
	Regulatory Capital Requirements
	The Company is a bank holding company under the supervision of the Federal Reserve Bank of San Francisco. Bank holding companies are subject to capital adequacy requirements of the Federal Reserve Board under the Bank Holding Company Act of 1956, as amended, and the regulations of the Federal Reserve Board. Heritage Bank is a federally insured institution and thereby is subject to the capital requirements established by the FDIC. The Federal Reserve Board capital requirements generally parallel the FDIC requirements. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements and operations. Management believes the Company and the Bank meet all capital adequacy requirements to which they are subject.
	On June 19, 2013, the Company merged its two subsidiary banks, Heritage Bank and Central Valley Bank, with Central Valley Bank being merged into Heritage Bank. Therefore, the tables below do not show the capital ratios for Central Valley Bank at December 31, 2013.
	Pursuant to minimum capital requirements of the FDIC, Heritage Bank and Central Valley Bank were required to maintain a leverage ratio (Tier 1 capital to average assets ratio) of 4.0% and risk-based capital ratios of Tier 1 capital and total capital (to total risk-weighted assets) of 4.0% and 8.0%, respectively. As of December 31, 2013 and December 31, 2012, the most recent regulatory notifications categorized Heritage Bank and Central Valley Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Banks’ categories.

	In July 2013, the Federal banking regulators approved a final rule to implement the revised capital adequacy standards of the Basel Committee on Banking Supervision, commonly called Basel III, and to address relevant provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act). The final rule strengthens the definition of regulatory capital, increases risk-based capital requirements, makes selected changes to the calculation of risk-weighted assets, and adjusts the prompt corrective action thresholds. Community banking organizations, such as the Company and the Bank, become subject to the new rule on January 1, 2015 and certain provisions of the new rule will be phased in over the period of 2015 through 2019. The final rule:
	•	Permits banking organizations that had less than $15 billion in total consolidated assets as of December 31, 2009, or were mutual holding companies as of May 19, 2010, to include in Tier 1 capital trust preferred securities and cumulative perpetual preferred stock that were issued and included in Tier 1 capital prior to May 19, 2010, subject to a limit of 25% of Tier 1 capital elements, excluding any non-qualifying capital instruments and after all regulatory capital deductions and adjustments have been applied to Tier 1 capital.
	•	Establishes new qualifying criteria for regulatory capital, including new limitations on the inclusion of deferred tax assets and mortgage servicing rights.
	•	Requires a minimum ratio of common equity Tier 1 capital to risk-weighted assets of 4.5%.
	•	Increases the minimum Tier 1 capital to risk-weighted assets ratio requirement from 4% to 6%.
	•	Retains the minimum total capital to risk-weighted assets ratio requirement of 8%.
	•	Establishes a minimum leverage ratio requirement of 4%.
	•	Retains the existing regulatory capital framework for 1-4 family residential mortgage exposures.
	•	Permits banking organizations that are not subject to the advanced approaches rule, such as the Company and the Bank, to retain, through a one-time election, the existing treatment for most accumulated other comprehensive income, such that unrealized gains and losses on securities available for sale will not affect regulatory capital amounts and ratios.
	•	Implements a new capital conservation buffer requirement for a banking organization to maintain a common equity capital ratio more than 2.5% above the minimum common equity Tier 1 capital, Tier 1 capital and total risk-based capital ratios in order to avoid limitations on capital distributions, including dividend payments, and certain discretionary bonus payments. The capital conservation buffer requirement will be phased in beginning on January 1, 2016 at 0.625% and will be fully phased in at 2.50% by January 1, 2019. A banking organization with a buffer of less than the required amount would be subject to increasingly stringent limitations on such distributions and payments as the buffer approaches zero. The new rule also generally prohibits a banking organization from making such distributions or payments during any quarter if its eligible retained income is negative and its capital conservation buffer ratio was 2.5% or less at the end of the previous quarter. The eligible retained income of a banking organization is defined as its net income for the four calendar quarters preceding the current calendar quarter, based on the organization’s quarterly regulatory reports, net of any distributions and associated tax effects not already reflected in net income.
	•	Increases capital requirements for past-due loans, high volatility commercial real estate exposures, and certain short-term commitments and securitization exposures.
	•	Expands the recognition of collateral and guarantors in determining risk-weighted assets.
	•	Removes references to credit ratings consistent with the Dodd-Frank Act and establishes due diligence requirements for securitization exposures.
	The Company’s management is currently evaluating the provisions of the final rule and their expected impact on the Company.

	(b) Commitments to Extend Credit
	In the ordinary course of business, the Company may enter into various types of transactions that include commitments to extend credit that are not included in the Consolidated Financial Statements. The Company applies the same credit standards to these commitments as it uses in all its lending activities and have included these commitments in its lending risk evaluations. The Company’s exposure to credit loss under commitments to extend credit is represented by the amount of these commitments.

	(c) Regulatory and Legal Proceedings
	The Company is involved in numerous business transactions, which, in some cases, depend on regulatory determination as to compliance with rules and regulations. Also, the Company has certain litigation and negotiations in progress. All such matters are attributable to activities arising from normal operations, except the proposed merger as mentioned below. In the opinion of management, after review with legal counsel, the eventual outcome of the aforementioned matters, including the proposed merger, is unlikely to have a materially adverse effect on the Company’s Consolidated Financial Statements or its financial position.
	On October 23, 2013, the Company announced the signing of a merger agreement with Washington Banking with Washington Banking merging into Heritage. Washington Banking, its directors and Heritage are named as defendants in two lawsuits pending in the Superior Court for the State of Washington in King County, Washington, which have been consolidated under the caption In Re Washington Banking Company Shareholder Litigation, Lead Case No. 13-2-38689-5 SEA. The consolidated litigation generally alleges that Washington Banking’s directors breached their fiduciary duties to Washington Banking and its shareholders by agreeing to the proposed merger at an unfair price and without an adequate sales process, because they have interests in the merger different from shareholders and by agreeing to deal protection provisions in the merger agreement that are alleged to prevent bids by third parties. The consolidated litigation also alleges that the disclosures in connection with the merger are misleading in various respects. Heritage is alleged to have aided and abetted the directors’ alleged breaches of their fiduciary duties.  The consolidated litigation seeks, among other things, an order enjoining the defendants from consummating the proposed merger, as well as attorneys’ and experts’ fees and certain other damages.
	Heritage believes that the aiding and abetting claim against it lacks merit. Washington Banking and its directors and Heritage separately filed motions to dismiss the claims against them.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Fair Value Measurements
	Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:
	Level 1: Valuations for assets and liabilities traded in active exchange markets, or interest in open-end mutual funds that allow the Company to sell its ownership interest back to the fund at net asset value on a daily basis. Valuations are obtained from readily available pricing sources for market transactions involving identical assets, liabilities, or funds.
	Level 2: Valuations for assets and liabilities traded in less active dealer, or broker markets, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or valuations using methodologies with observable inputs.
	Level 3: Valuations for assets and liabilities that are derived from other valuation methodologies, such as option pricing models, discounted cash flow models and similar techniques using unobservable inputs, and not based on market exchange, dealer, or broker traded transactions. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities.
	(a) Recurring and Nonrecurring Basis
	The Company used the following methods and significant assumptions to estimate fair value of certain assets on a recurring and nonrecurring basis:
	Investment Securities Available for Sale and Held to Maturity:
	The fair value of all investment securities are based upon the assumptions market participants would use in pricing the security. If available, investment securities are determined by quoted market prices (Level 1). For investment securities where quoted market prices are not available, fair values are calculated based on market prices on similar securities (Level 2). Level 2 includes U.S. Treasury, U.S. government and agency debt securities, municipal securities, corporate securities and mortgage-backed securities and collateralized mortgage obligations-residential. For investment securities where quoted prices or market prices of similar securities are not available, fair values are calculated by using observable and unobservable inputs such as discounted cash flows or other market indicators (Level 3). Security valuations are obtained from third party pricing services for comparable assets or liabilities.
	Impaired Loans:
	At the time a loan is considered impaired, its impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, a loan’s observable market prices, or fair market value of the collateral if the loan is collateral-dependent. Impaired loans for which impairment is measured using the discounted cash flow approach are not considered to be measured at fair value because the loan’s effective interest rate is not a fair value input, and for the purposes of fair value disclosures, the fair value of these loans are measured commensurate with non-impaired loans. Generally, the Company utilizes the fair market value of the collateral, which is commonly based on recent real estate appraisals, to measure impairment. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business (Level 3). Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly.
	Other Real Estate Owned:
	Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in Level 3 classification of the inputs for determining fair value.
	Appraisals for both collateral-dependent impaired loans and other real estate owned are performed by certified general appraisers for commercial properties or certified residential appraisers for residential properties whose qualifications and licenses have been reviewed and verified by the Company. Once received, the Company reviews the assumptions and approaches utilized in the appraisal as well as the resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. On a quarterly basis, the Company compares the actual selling price of collateral that has been liquidated to the most recent appraised value to determine what additional adjustment should be made to the appraisal value to arrive at fair value.
	The following table summarizes the balances of assets measured at fair value on a recurring basis as of December 31, 2013 and December 31, 2012.

(b) Fair Value of Financial Instruments
Because broadly traded markets do not exist for most of the Company’s financial instruments, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein do not represent, and should not be construed to represent, the underlying value of the Company.
The tables below present the carrying value amount of the Company’s financial instruments and their corresponding estimated fair values at the dates indicated.

The methods and assumptions, not previously presented, used to estimate fair value are described as follows:
Cash and Cash Equivalents:
The fair value of financial instruments that are short-term or reprice frequently and that have little or no risk are considered to have a fair value equal to carrying value (Level 1).
Other Interest Earning Deposits:
These deposits with other banks have maturities greater than three months. The fair value is calculated based upon market prices for similar deposits (Level 2).
FHLB Stock:
FHLB of Seattle stock is not publicly traded, as such, it is not practicable to determine the fair value of FHLB stock due to restrictions placed on its transferability.
Loans Receivable and Loans Held for Sale:
Except for impaired loans discussed previously, fair value is based on discounted cash flows using current market rates applied to the estimated life (Level 3). While these methodologies are permitted under U.S. GAAP, they are not based on the exit price concept of the fair value required under ASC 820-10, Fair Value Measurements and Disclosures, and generally produces a higher value.
Accrued Interest Receivable/Payable:
The fair value of accrued interest receivable/payable balances are determined using inputs and fair value measurements commensurate with the asset from which the accrued interest is generated. The carrying amounts of accrued interest approximate fair value (Level 1, Level 2, and Level 3).
Deposits:
For deposits with no contractual maturity, the fair value is assumed to equal the carrying value (Level 1). The fair value of fixed maturity deposits is based on discounted cash flows using the difference between the deposit rate and the rates offered by the Company for deposits of similar remaining maturities (Level 2).
Securities Sold Under Agreement to Repurchase:
Securities sold under agreement to repurchase are short-term in nature, repricing on a daily basis. Fair value financial instruments that are short-term or reprice frequently and that have little or no risk are considered to have a fair value equal to carrying value (Level 1).
Off-Balance Sheet Financial Instruments:
The majority of our commitments to extend credit, standby letters of credit and commitments to sell mortgage loans carry current market interest rates if converted to loans. As such, no premium or discount was ascribed to these commitments (Level 1). They are excluded from the preceding tables.

	Under the terms of the merger agreement, Washington Banking shareholders will receive 0.89000 shares of Heritage common stock and $2.75 in cash for each share of Washington Banking common stock. Based on the closing price of Heritage common stock of $16.72 on December 20, 2013, the consideration value for Washington Banking was approximately $276.8 million in aggregate. Upon consummation, the shareholders of Washington Banking will own approximately 46% of the combined company and the shareholders of Heritage will own approximately 54%. As of September 30, 2013, Washington Banking had approximately $1.6 billion in total assets.
	The merger agreement has been unanimously approved by the boards of directors of Heritage and Washington Banking. The merger is subject to regulatory approvals, approval by Heritage and Washington Banking shareholders, and certain other customary closing conditions. As of date of this Form 10-K, the Company has received approval for the bank merger from the FDIC and the DFI and a waiver from the FRB. There can be no assurance that the regulatory approvals received will not contain a condition or requirement that results in a failure to satisfy the conditions to closing set forth in the merger agreement. The merger is expected to close in the first half of 2014. The transaction is intended to qualify as a tax-free reorganization for U.S. federal income tax purposes and Washington Banking shareholders are not expected to recognize any taxable gain or loss in connection with the share exchange to the extent of the stock consideration received.
	For further information, reference is made to the Form 8-K filed by the Company with the SEC on October 24, 2013 and the Form S-4/A filed by the Company with the SEC on February 27, 2014.

Description of Business	'
	Description of Business
	Heritage Financial Corporation (the “Company”) is a bank holding company that was incorporated in the State of Washington in August 1997. The Company is primarily engaged in the business of planning, directing and coordinating the business activities of its wholly-owned subsidiary Heritage Bank (the “Bank”). The Bank is a Washington-chartered commercial bank and its deposits are insured by the FDIC under the Deposit Insurance Fund (“DIF”). The Bank is headquartered in Olympia, Washington and conducts business from its thirty-five branch offices located throughout Washington state and the greater Portland, Oregon area. The Bank’s business consists primarily of lending and deposit relationships with small businesses and their owners in its market areas and attracting deposits from the general public. The Bank also makes real estate construction and land development loans and consumer loans and originates first mortgage loans on residential properties located in western and central Washington State and the greater Portland, Oregon area.
	The Company has expanded its footprint through acquisitions beginning with the FDIC-assisted acquisition of Cowlitz Bank, a Washington chartered commercial bank headquartered in Longview, Washington effective on July 30, 2010. Heritage Bank entered into a definitive agreement with the FDIC, pursuant to which Heritage Bank acquired certain assets and assumed certain liabilities of Cowlitz Bank (the “Cowlitz Acquisition”). The Cowlitz Acquisition included nine branches of Cowlitz Bank, including its division Bay Bank, which opened as branches of Heritage Bank on August 2, 2010. It also included the Trust Services Division of Cowlitz Bank.
	Effective November 5, 2010, Heritage Bank entered into a definitive agreement with the FDIC, pursuant to which Heritage Bank acquired certain assets and assumed certain liabilities of Pierce Commercial Bank, a Washington chartered commercial bank headquartered in Tacoma, Washington (the “Pierce Commercial Acquisition”). The Pierce Commercial Acquisition included one branch, which opened as a branch of Heritage Bank as of November 8, 2010.
	On September 14, 2012, the Company and the Bank entered into a definitive agreement to acquire Northwest Commercial Bank (“NCB”), a Washington chartered commercial bank headquartered in Lakewood, Washington (the “NCB Acquisition”). The NCB Acquisition was completed on January 9, 2013, with the merger of NCB into Heritage Bank. See Note 2, “Business Combinations” for additional information.
	On March 11, 2013, the Company entered into a definitive agreement to acquire Valley Community Bancshares, Inc. ("Valley" or "Valley Community Bancshares") and its wholly-owned subsidiary, Valley Bank, both headquartered in Puyallup, Washington (the “Valley Acquisition”). The Valley Acquisition was completed on July 15, 2013. See Note 2, “Business Combinations” for additional information.
	On April 8, 2013, the Company announced the proposed merger of its two wholly-owned bank subsidiaries Central Valley Bank and Heritage Bank, with Central Valley Bank merging into Heritage Bank. The common control merger was completed on June 19, 2013 and on a consolidated basis had no accounting impact on the Company. Central Valley Bank now operates as a division of Heritage Bank.
	On October 23, 2013, the Company, along with the Bank, and Washington Banking Company (“Washington Banking”) and its wholly owned subsidiary bank, Whidbey Island Bank ("Whidbey") jointly announced the signing of a merger agreement under which Heritage and Washington Banking will enter into a strategic merger with Washington Banking merging into Heritage. Immediately following the merger, Whidbey will merge into the Bank. Washington Banking branches will adopt the Heritage Bank name in all markets, with the exception of six branches in Whidbey Island markets which will continue to operate using the Whidbey Island Bank name. The corporate headquarters of the combined company will be in Olympia, Washington. The merger is anticipated to be completed in the second quarter of 2014. See "Note 22 - Proposed Merger" for additional information.
Basis of Presentation	'
	Basis of Presentation
	The accounting and reporting policies of the Company and its subsidiary confirm to U.S. Generally Accepted Accounting Principles (“GAAP”). In preparing the Consolidated Financial Statements management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of financial statements and the reported amounts of income and expenses during the reporting periods. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, other than temporary impairments in the fair value of investment securities, expected cash flows of purchased loans and related indemnification asset, fair value measurements, stock-based compensation, impairment of goodwill and other intangible assets and income taxes. Actual results could differ from these estimates.
	The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiary. All significant intercompany balances and transactions among the Company and its subsidiary have been eliminated in consolidation.
	Certain prior year amounts have been reclassified to conform to the current period’s presentation. Reclassifications had no effect on prior year net income or stockholders’ equity.
Significant Accounting Policies	'
	Significant Accounting Policies
	Cash and Cash Equivalents
	For purposes of reporting cash flows, cash and cash equivalents includes cash on hand and in banks, interest earning deposits with original maturities of 90 days or less, and federal funds sold. Net cash flows are reported for customer loan and deposit transactions, other interest bearing deposits, federal funds sold and repurchase agreements.
	Investment Securities
	The Company identifies investments as held to maturity or available for sale at the time of acquisition. Securities are classified as held to maturity when the Company has the ability and positive intent to hold them to maturity. Securities classified as available for sale are available for future liquidity requirements and may be sold prior to maturity.
	Investment securities held to maturity are recorded at cost, adjusted for amortization of premiums or accretion of discounts using the interest method. Securities available for sale are carried at fair value. Unrealized gains and losses on securities available for sale are excluded from earnings and are reported in other comprehensive income, net of related income taxes. Realized gains and losses on sale of investment securities are computed on the specific identification method.
	Management evaluates securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Although these evaluations involve significant judgment, an unrealized loss in the fair value of a debt security is generally deemed to be temporary when the fair value of the security is below the carrying value primarily due to changes in interest rates, there has not been significant deterioration in the financial condition of the issuer, and it is not more likely than not that the Company will be required to sell the security before the anticipated recovery of its remaining carrying value. If any of these criteria is not met, the impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. An unrealized loss in the value of an equity security is generally considered temporary when the fair value of the security is below the carrying value primarily due to current market conditions and not deterioration in the financial condition of the issuer, and it is not more likely than not that the Company will be required to sell the security before the anticipated recovery of its remaining carrying value. Other factors that may be considered in determining whether a decline in the value of either a debt or an equity security is “other than temporary” include ratings by recognized rating agencies; actions of commercial banks or other lenders relative to the continued extension of credit facilities to the issuer of the security; the financial condition, capital strength and near-term prospects of the issuer and recommendations of investment advisors or market analysts. If any of these criteria is not met, the entire difference between amortized cost and fair value is recognized as impairment through earnings, and a new cost basis is established for the security. Continued deterioration of market conditions could result in additional impairment losses recognized within the investment portfolio.
	Loans Receivable and Loans Held for Sale
	Loans Held for Sale:
	Mortgage loans held for sale are carried at the lower of amortized cost or market value determined on an aggregate basis. Any loan that management determines will not be held to maturity is classified as held for sale at the time of origination, purchase or securitization, or when such decision is made. Unrealized losses on such loans are included in income.
	Originated Loans:
	Originated loans are generally recorded at their outstanding principal balance adjusted for charge-offs, the allowance for loan losses and deferred fees and costs. Interest on loans is calculated using the simple interest method based on the daily balance of the principal amount outstanding and is credited to income as earned. Loans are considered past due or delinquent when principal or interest payments are past due 30 days or more. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. Delinquent loans may remain on accrual status between 30 days and 89 days past due. The accrual of interest is discontinued at the time the loan is 90 days delinquent unless the credit is well secured and in the process of collection. Loans are placed on nonaccrual at an earlier date if collection of the contractual principal or interest is doubtful. All interest accrued but not collected on loans deemed nonaccrual during the period is reversed against interest income in that period. The interest payments received on nonaccrual loans is accounted for on the cost-recovery method whereby the interest payment is applied to the principal balances. Loans may be returned to accrual status when improvements in credit quality eliminate the doubt as to the full collectability of both interest and principal and a period of sustained performance has occurred. Substantially all loans that are nonaccrual are also impaired. Income recognition on impaired loans conforms to that used on nonaccrual loans
	Loans are charged-off if collection of the contractual principal or interest as scheduled in the loan agreement is doubtful. Credit card loans and other consumer loans are typically charged-off no later than 180 days past due.
	Purchased Covered and Purchased Non-Covered Loans:
	Loans acquired in a business combination are designated as “purchased” loans. These loans are recorded at their fair value at acquisition date, factoring in credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for loan losses is not carried over or recorded as of the acquisition date. Purchased loans subject to FDIC shared-loss agreements are identified as “covered” on the Consolidated Statements of Financial Condition, while purchased loans not subject to FDIC shared-loss agreements are referred to as “non-covered”. The covered loans have an additional evaluation separate from originated and purchased non-covered loans as they have shared-loss attributes which may reduce the Bank’s risk of loss. For further information see Note 7, “FDIC Indemnification Asset”.
	Loans purchased with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are accounted for under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“FASB ASC”) 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, formerly AICPA SOP 03-3 Accounting for Certain Loans or Debt Securities Acquired in a Transfer. These loans are identified as “purchased impaired” loans. In situations where such loans have similar risk characteristics, loans may be aggregated into pools to estimate cash flows. A pool is accounted for as a single asset with a single interest rate, cumulative loss rate and cash flow expectation. Expected cash flows at the acquisition date in excess of the fair value of loans are considered to be accretable yield, which is recognized as interest income over the life of the loan or pool using a level yield method if the timing and amount of the future cash flows of the pool is reasonably estimable.
	The cash flows expected over the life of the purchased impaired loan or pool are estimated quarterly using an internal cash flow model that projects cash flows and calculates the carrying values of the pools, book yields, effective interest income and impairment, if any, based on pool level events. Assumptions as to default rates, loss severity and prepayment speeds are utilized to calculate the expected cash flows. To the extent actual or projected cash flows are less than previously estimated, additional provisions for loan losses on the purchased loan portfolios will be recognized immediately into earnings. To the extent actual or projected cash flows are more than previously estimated, the increase in cash flows is recognized immediately as a recapture of provision for loan losses up to the amount of any provision previously recognized for that pool of loans, if any, then prospectively recognized in interest income as a yield adjustment. Any disposals of loans, including sales of loans, and payments in full or foreclosures result in the removal of the loan from the loan pool at the carrying amount.
	Loans accounted for under FASB ASC 310-30 are generally considered accruing and performing loans as the loans accrete interest income over the estimated life of the loan when cash flows are reasonably estimable. Accordingly, purchased impaired loans that are contractually past due are still considered to be accruing and performing loans. If the timing and amount of cash flows is not reasonably estimable, the loans may be classified as nonaccrual loans and interest income may be recognized on a cash basis or as a reduction of the principal amount outstanding.
	Loans purchased that are not accounted for under FASB ASC 310-30 are accounted for under FASB ASC 310-20, Receivables—Nonrefundable fees and Other Costs, formerly SFAS 91 Nonrefundable fees and Other Costs, which considers the contractual cash flows. These loans are identified as “purchased other” loans, and are initially recorded at their fair value, which is estimated using an internal cash flow model and assumptions similar to the FASB ASC 310-30 loans. The difference between the estimated fair value and the unpaid principal balance at acquisition date is recognized as interest income over the life of the loan using an effective interest method for non-revolving credits or a straight-line method, which approximates the effective interest method, for revolving credits. Any unrecognized discount for a loan that is subsequently repaid or fully charged-off will be recognized immediately into income.
	Impaired Loans and Troubled Debt Restructures
	Impaired Loans:
	A loan is considered impaired when, based on current information and events, it is probable the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrowers, including length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amounts of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral (less cost to sell) if the loan is collateral dependent.
	Troubled Debt Restructures:
	A troubled debt restructured loan (“TDR”) is a restructuring in which the Bank, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to a borrower that it would not otherwise consider. These concessions may include changes of the interest rate, forbearance of the outstanding principal or accrued interest, extension of the maturity date, delay in the timing of the regular payment, or any other actions intended to minimize potential losses. The Bank does not forgive principal for a majority of their TDRs, but in those situations where principal is forgiven, the entire amount of such principal forgiveness is immediately charged off to the extent not done so prior to the modification. The Bank also considers insignificant delays in payments when determining if a loan should be classified as a TDR.
	A loan that has been placed on nonaccrual status that is subsequently restructured will usually remain on nonaccrual status until the borrower is able to demonstrate repayment performance in compliance with the restructured terms for a sustained period, typically for six months. A restructured loan may return to accrual status sooner based on other significant events or mitigating circumstances. A loan that has not been placed on nonaccrual status may be restructured and such loan may remain on the accrual status after such restructuring. In these circumstances, the borrower has made payments before and after the restructuring. Generally, this restructuring involves a reduction in the loan interest rate and/or a change to interest-only payments for a period of time. The restructured loan is considered impaired despite the accrual status and a specific valuation allowance is calculated similar to the impaired loans.
	A TDR is considered defaulted if, during the 12-month period after the restructure, the loan has not performed in accordance to the restructured terms. Defaults include loans whose payments are 90 days or more past due and loans whose revised maturity date passed and no further modifications will be granted for that borrower.
	A loan may subsequently be excluded from the TDR disclosures if (i) the restructured interest rate was greater than or equal to the interest rate of a new loan with comparable risk at the time of the restructure, and (ii) the loan is no longer impaired based on the terms of the restructured agreement. The Bank's policy is that the borrower must demonstrate a sustained period, typically six consecutive months, of payments in accordance with the modified loan before it can be reviewed for removal from the TDR disclosure under the second criteria. However, the loan must be reported as a TDR in at least one annual report on Form 10-K. Once a loan has been classified as a TDR, it will continue to be disclosed as an impaired loan until paid off or charged-off, even if the loan subsequently is no longer disclosed as a TDR.
	Loan Fees
	Loan origination fees and certain direct origination costs are deferred and amortized as an adjustment of the yields of the loans over their contractual lives, adjusted for prepayment of the loans, using the effective interest method or the straight-line method, which approximates the effective interest method. In the event loans are sold, the net deferred loan origination fees or costs are recognized as a component of the gains or losses on the sales of loans.
	Allowance for Loan Losses
	Allowance for Loan Losses on Originated Loans:
	The allowance for loan losses is a reserve established through a provision for loan losses charged to expense, which represents management’s best estimate of probable losses that have been incurred within the existing portfolio of originated loans. For further information on the policy on purchased loans, see “Allowance for Loan Losses on Purchased Loans” below. The allowance, in the judgment of management, is necessary to reserve for estimated loan losses and risks inherent in the loan portfolio. The Company’s allowance for loan losses methodology includes allowance allocations calculated in accordance with FASB ASC 310, Receivables and allowance allocations calculated in accordance with FASB ASC 450, Contingencies. Accordingly, the methodology is based on historical loss experience by type of credit and internal risk grade, specific homogeneous risk pools and specific loss allocations, with adjustments for current events and conditions. The Company’s process for determining the appropriate level of the allowance for loan losses is designed to account for credit deterioration as it occurs. The provision for loan losses reflects loan quality trends, including the levels of and trends related to nonaccrual loans, past due loans, potential problem loans, criticized loans and net charge-offs or recoveries, among other factors. The provision for loan losses also reflects the totality of actions taken on all loans for a particular period. In other words, the amount of the provision reflects not only the necessary increases in the allowance for loan losses related to newly identified criticized loans, but it also reflects actions taken related to other loans including, among other things, any necessary increases or decreases in required allowances for specific loans or loan pools. Losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance.
	The level of the allowance reflects management’s continuing evaluation of known and inherent risks in the loan portfolio. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off.
	The Company’s allowance for loan losses consists of three elements: (i) specific valuation allowances determined in accordance with FASB ASC 310 based on probable losses on specific loans; (ii) historical loss factor determined in accordance with FASB ASC 450 based on historical loan loss experience for similar loans with similar characteristics and trends; and (iii) an environmental loss factor to reflect the impact of current conditions, as determined in accordance with FASB ASC 450 based on general economic conditions and other qualitative risk factors both internal and external to the Company. The historical loss factor and environmental loss factor are combined and multiplied against the outstanding principal balance of loans in the pool of similar loans with similar characteristics. The Company’s pools of similar loans are grouped by class of loan.
	The allowances established for probable losses on specific loans are based on a regular analysis and evaluation of problem loans. Loans are classified based on an internal credit risk grading process that evaluates, among other things: (i) the obligor’s ability to repay; (ii) the underlying collateral, if any; and (iii) the economic environment and industry in which the borrower operates. This analysis is performed at the loan officer level for all loans. When a loan is performing but has an assigned risk grade greater than pass, the loan officer analyzes the loan to determine an appropriate monitoring and collection strategy. When a loan is nonperforming or has been classified as a nonaccrual loan, a member from the special assets department will analyze the loan to determine if it is impaired. If the loan is considered impaired, the special asset department will evaluate the need for a specific valuation allowance on the loan. Specific valuation allowances are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies and economic conditions affecting the borrower’s industry, among other things.
	Historical loss factors are calculated based on the historical loss experience and recovery experience of specific classes of loans. The Company calculates historical loss ratios for the classes of loans based on the proportion of actual charge-offs and recoveries experienced to the total population of loans in the pool for a rolling twelve quarter average.
	Environmental loss factors are based on general economic conditions and other qualitative risk factors both internal and external to the Company. In general, such valuation allowances are determined by evaluating, among other things: (i) levels of and trend in delinquencies and impaired loans; (ii) levels and trends in charge-offs and recoveries; (iii) effects of changes in risk selection and underwriting standards, and other changes in lending policies, procedures, and practices; (iv) experience, ability, and depth of lending management and other relevant staff; (v) national and local economic trends and conditions; (vi) external factors such as competition, legal, and regulatory and; (vii) effects of changes in credit concentrations. Management evaluates the degree of risk that each one of these components has on the quality of the loan portfolio on a quarterly basis. Each component is determined to be on a scale of risk. The results are then utilized in a matrix to determine an appropriate environmental loss factor for each class of loan. An additional environmental factor is added after the calculated matrix factor if the specific loan is risk graded greater than watch.
	The allowance for loan loss evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. While management utilizes its best judgment and information available to recognize losses on loans, future additions to the allowance may be necessary based on declines in local and national economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses. Such agencies may require the Bank to make adjustments to the allowance based on their judgments about information available to them at the time of their examinations. The Company believes the allowance for loan losses is appropriate given all the above considerations.
	The Bank is also party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheet. The Company has a policy in which it evaluates the risk on a quarterly basis, and provides for an allowance for credit losses, as necessary. The methodology is similar to the allowance for loan losses, and includes an estimate of the probability of drawdown of the loan commitment. Based on its analysis, the Company has recorded an allowance for off-balance sheet financial instruments of $110,000 and $75,000 as of December 31, 2013 and 2012, respectively.
	Allowance for Loan Losses on Purchased Loans:
	The purchased loans acquired in all the Acquisitions are subject to the Company’s internal and external credit review. Under the accounting guidance of FASB ASC 310-30, the allowance for loan losses on purchased impaired loans is measured at each financial reporting period, or measurement date, based on expected cash flows. If and when credit deterioration, or decreases in expected cash flows initially estimated, occurs subsequent to the acquisition date, a provision for loan losses for purchased loans will be charged to earnings as of the measurement date. For the purchased covered loans, a provision for loan losses will be charged to earnings for the full amount without regard to the FDIC shared-loss agreement, and the portion of the loss reimbursable from the FDIC is recorded in noninterest income and increases the FDIC indemnification asset.
	The purchased other loans not accounted for under FASB ASC 310-30 and the balances funded on purchased loans after the acquisition date, called “subsequent advances”, are also subject to the Company’s credit reviews. An allowance for loan loss is estimated in a similar manner as the originated loan portfolio, and a provision for loan loss is charged to earnings as necessary. Management also reviews historical and environmental factors specific to the purchased portfolios which may be slightly different than the originated loan portfolio.
	FDIC Indemnification Asset
	The FDIC indemnification asset was measured at estimated fair value at acquisition date on the same basis as the purchased covered loans, and represents the present value of the estimated losses on covered loans to be reimbursed by the FDIC. The present value was calculated using the shorter of the shared-loss agreement terms or the life of the loan. Under the terms of the FDIC shared-loss agreements, the FDIC will absorb 80% of losses and receive 80% of loss recoveries for the covered loans. The FDIC indemnification asset will be reduced as losses are recognized on covered loans and shared-loss payments are received from the FDIC. Since the FDIC indemnification asset was initially recorded at estimated fair value using a discount rate, a portion of the discount is taken into noninterest income at each reporting date.
	The FDIC indemnification asset is evaluated quarterly. Realized losses in excess of prior estimates will immediately increase the FDIC indemnification asset by a credit to noninterest income. Conversely, if realized losses are less than prior estimates, the FDIC indemnification asset will be reduced by a charge to noninterest income on a prospective basis, and any change in value would be limited to the contractual terms of the shared-loss agreement.
	Mortgage Banking Operations
	Until the second quarter of 2013, the Company sold one-to-four family residential mortgage loans on a servicing released basis and recognized a cash gain or loss. A cash gain or loss was recognized to the extent that the sales proceeds of the mortgage loans sold exceeded or were less than the net book value at the time of sale. Income from mortgage loans brokered to other lenders was recognized into income on date of loan closing.
	Commitments to sell one-to-four family residential mortgage loans were made primarily during the period between the taking of the loan application and the closing of the mortgage loan. The timing of making these sale commitments was dependent upon the timing of the borrower’s election to lock-in the mortgage interest rate and fees prior to loan closing. Most of these sale commitments were made on a best-efforts basis whereby the Bank was only obligated to sell the mortgage if the mortgage loan was approved and closed by the Bank. Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans were accounted for as free standing derivatives. Fair values of these mortgage derivatives were estimated based on changes in mortgage interest rates from the date the interest on the loan was locked. The Company entered into forward commitments for the future delivery of mortgage loans when interest rate locks were entered into, in order to hedge the change in interest rates resulting from its commitments to fund the loans. Changes in the fair values of these derivatives were included in gains on sales of loans. As there were no loans held for sale at December 31, 2013, there was no associated derivative. The fair value of these derivative instruments was not significant at December 31, 2012 and 2011.
	Other Real Estate and Other Assets Owned
	Other real estate acquired by the Company in satisfaction of debt are held for sale and recorded at fair value at time of foreclosure. When property is acquired, it is recorded at the estimated fair value (less the costs to sell) at the date of acquisition, not to exceed net realizable value, and any resulting write-down is charged to the allowance for loan losses. Upon acquisition, all costs incurred in maintaining the property are expensed. Costs relating to the development and improvement of the property, however, are capitalized to the extent of the property’s net realizable value.
	Premises and Equipment
	Premises and equipment, including leasehold improvements, are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets or the lease period, whichever is shorter. The estimated useful lives used to compute depreciation and amortization for buildings and building improvements is 15 to 39 years; and for furniture, fixtures and equipment is three to seven years. The Company reviews buildings, leasehold improvements and equipment for impairment whenever events or changes in the circumstances indicate that the undiscounted cash flows for the property are less than its carrying value. If identified, an impairment loss is recognized through a charge to earnings based on the fair value of the property.
	Other Intangible Assets
	The other intangible assets represents the Core Deposit Intangible (“CDI”) acquired in business combinations. The fair value of the CDI stemming from any given business combination is based on the present value of the expected cost savings attributable to the core deposit funding, relative to an alternative source of funding. The CDI is amortized over an estimated useful life which approximates the existing deposit relationships acquired on an accelerated method. The Company evaluates such identifiable intangibles for impairment when an indication of impairment exists.
	Goodwill
	The Company’s goodwill represents the excess of the purchase price over the fair value of net assets acquired in the purchases of Valley Community Bancshares in 2013, Western Washington Bancorp in 2006 and North Pacific Bank in 1998. The Company’s goodwill is assigned to Heritage Bank and is evaluated for impairment at the Heritage Bank level (reporting unit).
	In accordance with Accounting Standards Update ("ASU") 2011-08 Intangibles – Goodwill and Other (Topic 350), an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. In other words, before the first step of the existing guidance, the entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that the fair value of goodwill is less than carrying value. The qualitative assessment includes adverse events or circumstances identified that could negatively affect the reporting units’ fair value as well as positive and mitigating events. Such indicators may include, among others: a significant change in legal factors or in the general business climate; significant change in the Company’s stock price and market capitalization; unanticipated competition; and an action or assessment by a regulator. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step process is unnecessary. The entity has the option to bypass the qualitative assessment step for any reporting unit in any period and proceed directly to the first step of the exiting two-step process. The entity can resume performing the qualitative assessment in any subsequent period.
	The first step of the goodwill impairment test is performed, when considered necessary, by comparing the reporting unit’s aggregate fair value to its carrying value. Absent other indicators of impairment, if the aggregate fair value exceeds the carrying value, goodwill is not considered impaired and no additional analysis is necessary. If the carrying value of the reporting unit were to exceed the aggregate fair value, a second step would be performed to measure the amount of impairment loss, if any. To measure any impairment loss the implied fair value would be determined in the same manner as if the reporting unit were being acquired in a business combination. If the implied fair value of goodwill is less than the recorded goodwill, an impairment charge would be recorded for the difference.
	Income Taxes
	The Company and its subsidiary file a United States consolidated federal income tax return and an Oregon State income tax return. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates applicable to taxable income in the periods in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in income in the period that includes the enactment date.
	The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in “income taxes” in the Consolidated Statements of Income as the amounts are generally insignificant each year.
	Employee Stock Ownership Plan
	The Company sponsored an Employee Stock Ownership Plan (ESOP). The ESOP purchased 2% of the common stock issued in a January 1998 stock offering and borrowed $1.3 million from the Company in order to fund the purchase of the Company’s common stock. The loan to the ESOP was repaid in full as of December 31, 2012. When outstanding, the loan was repaid principally from the Bank's contributions to the ESOP. The Bank's contributions were sufficient to service the debt over the 15-year loan term at the interest rate of 8.5%. As the debt was repaid, shares were released and allocated to plan participants based on the proportion of debt service paid during the year. As shares were released, compensation expense was recorded equal to the then current market price of the shares and the shares became outstanding for earnings per common share calculations. Cash dividends on allocated shares were recorded as a reduction of retained earnings and paid or distributed directly to participants’ accounts. Cash dividends on unallocated shares were recorded as a reduction of debt and accrued interest.
Stock-Based Compensation
The Company maintains a number of stock-based incentive programs, which are discussed in more detail in Note 15, "Stock-Based Compensation." Compensation cost is recognized for stock options and restricted stock awards issued to employees and directors, based on the fair value of these awards at the date of grant. The Company did not grant stock option awards for the years ended December 31, 2013, 2012 or 2011. The fair value of stock options granted would be estimated on the date of grant using the Black-Scholes-Merton option pricing model. The market price of the Company’s common stock at the date of grant is used for the restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period, on a straight-line basis.
Deferred Compensation Plans
The Company has adopted a Deferred Compensation Plan and has entered into arrangements with certain executive officers. Under the Plan, participants are permitted to elect to defer compensation and the Company has the discretion to make additional contributions to the Plan on behalf of any participant based on a number of factors. Such discretionary contributions are generally approved by the Compensation Committee of the Company's Board of Directors. The notional account balances of participants under the Plan earn interest on an annual basis. The applicable interest rate is the Moody’s Seasoned Aaa Corporate Bond Yield as of January 1 of each year. Generally, a participant’s account is payable upon the earliest of the participant’s separation from service with the Company, the participant’s death or disability, or a specified date that is elected by the participant in accordance with applicable rules of the Internal Revenue Code. The Company’s obligation to make payments under the Plan is a general obligation of the Company and is to be paid from the Company’s general assets. As such, participants are general unsecured creditors of the Company with respect to their participation under the Plan. The Company records a liability within accrued expenses and other liabilities on the Consolidated Statements of Financial Condition in a systematic and rationale manner. Since the amounts earned are generally based on the Company’s annual performance, the Company records deferred compensation expense each year for an amount calculated based on that year’s financial performance.
Earnings per Share
Basic earnings per common share is net income available to common shareholders divided by the weighted average number of common shares outstanding during the period. ESOP shares are considered outstanding for this calculation unless unearned. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options. Earnings and dividends per share are restated for all stock splits and stock dividends through the date of issuance of the financial statements.
Operating Segments
While the Company’s chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Recently Issued Accounting Pronouncements	'
	Recently Issued Accounting Pronouncements
	FASB ASU 2011-11, Disclosures about Offsetting Assets and Liabilities, was issued in December 2011 to require an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. The adoption of the Update did not have a material effect on the Company’s Consolidated Financial Statements at the date of its adoption.
	FASB ASU 2012-6, Business Combinations (Topic 805): Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution, was issued in October 2012. The objective of the Update was to address the diversity in practice about how to interpret the terms “on the same basis” and “contractual limitations” when subsequently measuring an indemnification asset. This Update was effective for fiscal years and interim periods beginning on or after December 15, 2012. Early adoption was permitted, and adoption was to be applied prospectively to indemnification assets existing as of the date of adoption. The adoption of this Update did not have a material effect on the Company’s Consolidated Financial Statements at the date of adoption as the Company previously accounted for its indemnification asset in a manner consistent with the Update.
	FASB ASU 2013-2, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, was issued in February 2013. The Update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income (loss) by component and to present either on the face of the statement where net income is presented, or in the notes, significant amounts reclassified out of accumulated other comprehensive income (loss) by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. The amendments became effective for annual and interim reporting periods beginning on or after December 15, 2012. The adoption of this Update did not have a material effect on the Company’s Consolidated Financial Statements. The additional disclosures are included in Note 18, “Accumulated Other Comprehensive (Loss) Income.”
	FASB ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, A Similar Tax Loss, or a Tax Credit Carryforward Exists, was issued in July 2013. This Update provides that an unrecognized tax benefit, or a portion thereof, be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent that a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented as a liability. These amendments are effective for interim and annual reporting periods beginning after December 15, 2013. Early adoption and retrospective application is permitted. The Company is currently evaluating the impact of this amendment on the Consolidated Financial Statements.
Fair Value Measurements	'
	Loans Receivable and Loans Held for Sale:
	Except for impaired loans discussed previously, fair value is based on discounted cash flows using current market rates applied to the estimated life (Level 3). While these methodologies are permitted under U.S. GAAP, they are not based on the exit price concept of the fair value required under ASC 820-10, Fair Value Measurements and Disclosures, and generally produces a higher value.

During the year ended December 31, 2013, the Company's initial advance at the time of modification on these construction loans totaled $1.1 million and the total commitment amount was $4.3 million.

[1]	For the NCB Acquisition, the contractual cash flows were $8.5 million and the expected cash flows were $5.6 million, resulting in a non-accretable difference of $2.9 million. As the fair value of these purchased impaired loans at the January 9, 2013 NCB Acquisition date was $4.9 million, this provides an accretable yield of $745,000, which the Company included in the change in accretable yield in the quarter of acquisition.
[2]	For the Valley Acquisition, the contractual cash flows were $5.1 million and the expected cash flows were $4.4 million, resulting in a non-accretable difference of $692,000.
