	Description of Business, Basis of Presentation and Significant Accounting Policies
	(a) Description of Business
	Heritage Financial Corporation ("Heritage" or 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. The Bank is headquartered in Olympia, Washington and conducts business from its sixty-seven 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 primarily located in its market area.
	The Company has expanded its footprint through mergers and acquisitions beginning with its first acquisition in July 2010. The largest of these transactions was the strategic merger with Washington Banking Company (“Washington Banking”) and its wholly owned subsidiary bank, Whidbey Island Bank ("Whidbey") which was effective on May 1, 2014. The merger is referred to as the "Washington Banking Merger". The Washington Banking results since May 1, 2014 are included in this Quarterly Report on Form 10-Q. The strategic merger is described in more detail in "Note 2 - Business Combinations."
	(b) Basis of Presentation
	The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with Generally Accepted Accounting Principles (“GAAP”), for interim financial information, pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These Condensed Consolidated Financial Statements and accompanying Notes should be read with the Company's December 31, 2013 audited Consolidated Financial Statements and the accompanying Notes included in the Company's Annual Report on Form 10-K (“2013 Annual Form 10-K”). In management's opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. In preparing the Condensed Consolidated Financial Statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. Actual results could differ from those estimates. Estimates related to the allowance for loan losses, other than temporary impairments in the fair value of investment securities, expected cash flows of purchased credit impaired loans and related indemnification asset, fair value measurements, stock-based compensation, impairment of goodwill and other intangible assets and income taxes are particularly subject to change.
	Certain prior period amounts have been reclassified to conform to the current period’s presentation. Reclassifications had no effect on prior periods' net income or stockholders’ equity.
	As a result of the Washington Banking Merger, the Company reclassified its loan portfolio. Total loans receivable are now presented in two categories: noncovered loans receivable and covered loans receivable. A description of the categories is included below.
	Noncovered Loans Receivable: Noncovered loans are those that are not covered by FDIC shared-loss agreements and can include loans originated by the Company or acquired in mergers and acquisitions. Loans are stated at the unpaid principal balance, net of premiums, unearned discounts and net deferred loan origination fees and costs. The premiums and unearned discounts may include values determined in purchase accounting. The loans purchased in acquisitions included in this category include those accounted for under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, or those accounted for under ASC 310-20, Receivables - Nonrefundable fees and Other Costs.
	Covered Loans Receivable: Covered loans are those that are covered by FDIC shared-loss agreements. These include the majority of loans from the Company's acquisition of Cowlitz Bank, as well as loans from Washington Banking's acquisitions of City Bank and North County Bank, as then acquired by the Company in the Washington Banking Merger. The same accounting principles applicable to noncovered loans receivable apply to covered loans, with the added benefit of shared-loss agreements.
	(c) Significant Accounting Policies
	The significant accounting policies used in preparation of our Condensed Consolidated Financial Statements are disclosed in our 2013 Annual Form 10-K. There have not been any material changes in our significant accounting policies from those contained in our 2013 Annual Form 10-K. As a result of the Washington Banking Merger, the Company has added an additional significant accounting policy which is described below.
	Bank Owned Life Insurance: The Company acquired in the Washington Banking Merger fair value of $32.5 million in bank owned life insurance (“BOLI”). These policies insure the lives of certain current or former Whidbey officers, and name the Bank as beneficiary. Noninterest income is generated tax-free (subject to certain limitations) from the increase in the policies' underlying investments made by the insurance company.  The Bank is capitalizing on the ability to partially offset costs associated with employee compensation and benefit programs with the BOLI. BOLI is recorded at the amount that can be realized under the issuance contract at the statement of financial condition date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
	(d) Recently Issued Accounting Pronouncements
	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. The adoption of this amendment did not have a material impact on the Company's Condensed Consolidated Financial Statements.
	FASB ASU No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects, was issued in January 2014.  The objective of this amendment is to provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit. The amendments in the standard permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The standard will be effective for the Company beginning January 1, 2015; however, early adoption is permitted. The Company is currently reviewing the provisions of this Update to determine the impacts it may have on the Company’s financial condition or results of operations.
	FASB ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure, was issued in January 2014. This Update intends to reduce diversity in practice by clarifying when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The amendment states that the real estate property should be recognized upon either the creditor obtaining legal title or the borrower convening all interest through a deed in lieu of foreclosure or similar legal agreement. These amendments are effective for interim and annual reporting periods beginning after December 15, 2014. Early adoption is permitted. The Company adopted the amendments in first quarter of 2014. The adoption did not have an impact on the Company's Condensed Consolidated Financial Statements.
	FASB ASU 2014-09, Revenue from Contracts with Customers, was issued in May 2014. Under this Update, FASB created a new Topic 606 which is in response to a joint initiative of FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. generally accepted accounting principles and international financial reporting standards that would:
	1	Remove inconsistencies and weaknesses in revenue requirements.
	2	Provide a more robust framework for addressing revenue issues.
	3	Improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets.
	4	Provide more useful information to users of financial statements through improved disclosure requirements.
	5	Simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer.
	The amendments in this Update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The Company is currently evaluating the impact this new accounting standard will have on its Condensed Consolidated Financial Statements.
	FASB ASU 2014-11, Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures, was issued in June 2014. This Update aligns the accounting for repurchase-to-maturity transactions and repurchase agreements executed as a repurchase financing with the accounting for other typical repurchase agreements, such as secured borrowings. The guidance eliminates sale accounting and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement. The amendments in this ASU require new and expanded disclosures. These amendments are effective for interim or annual reporting periods beginning after December 15, 2014. Early adoption for a public company is prohibited. The Company does not anticipate the adoption will have a material impact on its Condensed Consolidated Financial Statements.

Business Combination	'
	Business Combination
	On October 23, 2013, the Company, along with the Bank, and Washington Banking and its wholly owned subsidiary bank, Whidbey, jointly announced the signing of a merger agreement for the Washington Banking Merger. The Washington Banking Merger was effective on May 1, 2014. Pursuant to the terms of the Washington Banking Merger, Washington Banking branches adopted the Heritage Bank name in all markets, with the exception of six branches in the Whidbey Island markets which will continue to operate using the Whidbey Island Bank name. The primary reasons for the merger were to expand the Company's geographic footprint consistent with its ongoing growth strategy and to achieve operational scale and realize efficiencies of a larger combined organization.
	Under the terms of the merger agreement, Washington Banking shareholders received 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 $16.16 on April 30, 2014, the fair value of the per share merger consideration paid to Washington Banking shareholders was approximately $224.2 million for 13,872,567 shares issued. The Company also paid $42.9 million in cash and incurred $489,000 in capitalized stock issuance costs. The terms of the merger agreement also stipulated immediate vesting of the Washington Banking options and restricted stock awards units. The estimated fair value of the 90,358 converted options issued was $481,000. The estimated fair value of the converted 129,462 restricted stock award units, of which 26,783 shares were surrendered at the request of the shareholder to pay applicable taxes, was approximately $2.1 million. The total consideration paid by the Company in conjunction with the Washington Banking Merger was $270.1 million and the total shares issued was 13,975,246.
	The transaction qualified as a tax-free reorganization for U.S. federal income tax purposes and Washington Banking shareholders did not recognize any taxable gain or loss in connection with the share exchange and the stock consideration received.
	The Washington Banking Merger resulted in $88.8 million of goodwill. This goodwill is not deductible for tax purposes.
	During the three and six months ended June 30, 2014, the Company incurred Washington Banking merger-related costs (including conversion costs) of approximately $5.3 million and $5.6 million, respectively. There were no Washington Banking merger-related costs during the three or six months ended June 30, 2013. However, the Company did incur $312,000 and $1.3 million of costs for the three and six months ended June 30, 2013, respectively, related to the Northwest Commercial and Valley Acquisitions and the Central Valley Bank merger, as discussed in the Annual Report on Form 10-K.
	Business Combination Accounting
	The Washington Banking Merger constitutes a business acquisition 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.  Heritage was considered the acquirer in this transaction. Accordingly, the preliminary estimates of fair values of the Washington Banking assets, including the identifiable intangible assets, and the assumed liabilities in the Washington Banking Merger were measured and recorded as of May 1, 2014. The Company expects to finalize the purchase price allocation by the end of 2014 when the valuation of acquired noncovered and covered loans is complete.
	The preliminary fair value estimates of the assets acquired and liabilities assumed in the Washington Banking Merger were as follows:
		1-May-14

	Net assets acquired	$	181,283
	A summary of the net assets purchased and the preliminary estimated fair value adjustments and resulting goodwill recognized from the Washington Banking Merger are presented in the following tables. Goodwill represents the excess of the consideration transferred over the estimated fair value of the net assets acquired and liabilities assumed.

	The operating results of the Company for the three and six months ended June 30, 2014 include the operating results produced by the net assets acquired in the Washington Banking Merger since the May 1, 2014 merger date. The Company has considered the requirement of FASB ASC 805 related to the contribution of the Washington Banking Merger to the Company’s results of operations. The table below presents only the significant results for the acquired business since the May 1, 2014 merger date.

	-3	Includes the accretion of the accretable yield on the purchased credit impaired loans and the accretion of the discount on the purchased non-credit impaired loans.
	-4	Excludes certain compensation and employee benefits for management as it is impracticable to determine due to the integration of the operations for this merger. Also includes certain merger-related costs incurred by the Company.
The Company also considered the pro forma requirements of FASB ASC 805. The following tables presents certain unaudited pro forma information, for illustrative purposes only, for the six month periods ended June 30, 2014 and 2013 as if Washington Banking had been acquired on January 1, 2013. The unaudited estimated pro forma information combines the historical results of Washington Banking with the Company's consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods. The pro forma information is not indicative of what would have occurred had the Washington Banking Merger occurred on January 1, 2013. In particular, no adjustments have been made to eliminate the impact of the Washington Banking loans which were previously accounted for under ASC 310-30 that may have been necessary had they been recorded at fair value at January 1, 2013. Additionally, Heritage expects to achieve further operating savings and other business synergies, including interest income growth, as a result of the Washington Banking Merger which are not reflective in the pro forma amounts that follow. As a result, actual amounts will differ from the unaudited pro forma information presented.

(A)	Adjustment of interest income from loans due to the estimated amortization of the new interest rate mark and the accretion of the acquisition accounting adjustment relating to the credit mark. The Washington Banking credit and interest rate marks and accretion recorded during the six months ended June 30, 2014 and 2013 as a result of its prior acquisitions were not adjusted.
(B)	Adjustments to reflect the amortization of the premium resulting from the fair value adjustment of the fixed rate maturities and the discount resulting from the fair value adjustment of the junior subordinated debentures.
(C)	As acquired loans and leases are recorded at fair value, the Company would expect a reduction in the historical provision for loan and leases losses from legacy Washington Banking; however, no adjustment to the historical amount of Washington Banking's provision for loan and lease losses is reflected in these pro forma statements.
(D)	Adjustment to reflect the amortization of the interest component of the fair value adjustment of the FDIC indemnification asset.
(E)	In connection with the Washington Banking Merger, Heritage recognized $5.6 million of direct merger-related expenses for the six month period ended June 30, 2014, which were excluded in this adjustment. Also, adjustment reflects the decrease in the depreciation expense as a result of the fair value adjustment to the premises and equipment, which effectively increased non-depreciable assets and decreased depreciable assets. Adjustment additionally reflects the amortization of assumed liabilities included in the the fair value adjustment of accrued expenses and other liabilities.
(F)	Income tax effect of pro forma adjustments at Company's statutory rate of 35%, excluding certain nondeductible costs included in the proforma adjustments.
(G) Earnings per common share, basic and diluted, were calculated using the calculated pro forma net income less dividends and undistributed earnings allocated to participating securities divided by the calculated pro forma basic and diluted weighted average shares outstanding. Basic and diluted weighted average common shares outstanding for the six months ended June 30, 2014 and 2013 were calculated by adding the applicable weighted average of the 13,975,246 shares issued by Heritage in conjunction with the Washington Banking Merger to the historical weighted average Heritage shares outstanding for the six months ended June 30, 2014 and 2013, respectively.

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 rate used in the valuations of the present value as of June 30, 2014 and 2013 was 9.4% and 6.4%, respectively, and the average prepayment rate for each period was 6.0%.
For the six months ended June 30, 2014, there were four private residential collateralized mortgage obligations determined to be other-than-temporarily impaired. All unrealized losses for the three and six months ended June 30, 2014 were deemed to be credit related, and the Company recorded the impairment in earnings. For the six months ended June 30, 2013, there were six private residential collateralized mortgage obligations determined to be other-than-temporarily impaired. The impairment for the three and six months ended June 30, 2013 was considered credit related and was recorded in earnings. No impairment for the three and six months ended June 30, 2014 and 2013 was recorded through other comprehensive income (loss).
The following table summarizes activity for the six months ended June 30, 2014 and 2013 related to the amount of impairments on held to maturity securities:

	Noncovered Loans Receivable
	The Company originates loans in the ordinary course of business and has also acquired loans through FDIC-assisted and open bank transactions. Loans that are not covered by FDIC shared-loss agreements are referred to as "noncovered loans." Disclosures related to the Company’s recorded investment in noncovered loans receivable generally exclude accrued interest receivable and net deferred loan origination fees and costs because they are insignificant.
	Loans acquired in a business combination may be further classified as “purchased” 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 credit impaired” ("PCI") 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.
	(a) Loan Origination/Risk Management
	The Company categorizes 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. Historically, the Company sold most single-family loans in the secondary market and retained a smaller portion in its loan portfolio. For the second quarter of 2013 until May 1, 2014, the Company only originated single-family loans for its loan portfolio. With the merger of Washington Banking, the Company again began originating and selling a majority of the single-family mortgages.
	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 regard 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 dependent upon 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.
	As a result of the Washington Banking Merger, the Company now originates indirect consumer loans. The Company makes loans for new and used automobile and recreational vehicles that are originated indirectly by selected dealers located in the Company's market areas. The Company has limited its indirect loan purchased primarily to dealerships that are established and well known in their market areas and to applicants that are not classified as sub-prime.
	Noncovered loans receivable at June 30, 2014 and December 31, 2013 consisted of the following portfolio segments and classes:

	(b) Concentrations of Credit
	Most of the Company’s lending activity occurs within Washington State, and to a lesser extent Oregon. The Company’s primary market areas have been concentrated along the I-5 corridor from Whatcom to Clark County in Washington State and Multnomah County in Oregon, as well as other contiguous markets. The Washington Banking Merger has allowed the expansion of the market area north of Seattle, Washington to the Canadian border. The majority of the Company’s loan portfolio consists of (in order of balances at June 30, 2014) non-owner occupied commercial real estate, commercial and industrial and owner-occupied commercial real estate. As of June 30, 2014 and December 31, 2013, 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 10. A description of the general characteristics of the risk grades is as follows:
	•	Grades 0 to 5: These grades are considered “pass grade” and include 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 6: This grade includes "Watch" loans and is considered a “pass grade”. The grade 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 7: 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 8: This grade includes “Substandard” loans in accordance with regulatory guidelines, 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 9: 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 10: 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 numerically graded at origination date as these loans are determined to be “pass graded” loans. These non-commercial loans may subsequently require numeric 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 estimated inherent losses, but to a lesser extent than the other loan grades. 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.
	The following tables present the balance of the noncovered loans receivable by credit quality indicator as of June 30, 2014 and December 31, 2013.

Noncovered potential problem loans are those loans that are currently accruing interest and are not considered impaired, but which management is monitoring because the financial information of the borrower causes concern as to their ability to meet their loan repayment terms. Noncovered potential problem loans also include PCI loans as these loans continue to accrete loan discounts established at acquisition based on the guidance of ASC 310-30. Noncovered potential problem loans as of June 30, 2014 and December 31, 2013 were $137.0 million and $52.8 million, respectively. The balance of noncovered potential problem loans guaranteed by a governmental agency, which guarantee reduces the Company's credit exposure, was $921,000 and $1.8 million as of June 30, 2014 and December 31, 2013, respectively.
(d) Nonaccrual Loans
Noncovered nonaccrual loans, segregated by segments and classes of loans, were as follows as of June 30, 2014 and December 31, 2013:

The Company had $2.3 million and $1.7 million of noncovered nonaccrual loans guaranteed by governmental agencies at June 30, 2014 and December 31, 2013, respectively.
Noncovered PCI loans are not included in the nonaccrual table above because the loans are accounted for under ASC 310-30, whereby accretable yield is calculated based on a loan's expected cash flow even if the loan is not performing under its conventional terms.
(e) Past due loans
The Company performs an aging analysis of past due loans using the categories of 30-89 days past due and 90 or more days past due. This policy is consistent with regulatory reporting requirements.
The balances of noncovered past due loans, segregated by segments and classes of loans, as of June 30, 2014 and December 31, 2013 were as follows:

For the three and six months ended June 30, 2014 and 2013, no interest income was recognized subsequent to a loan’s classification as nonaccrual. For the three and six months ended June 30, 2014, the Bank recorded $260,000 and $533,000, respectively, of interest income related to noncovered TDR performing loans. The Bank recorded $310,000 and $600,000 of interest income related to noncovered TDR performing loans for the three and six months ended June 30, 2013.
(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 ("performing") or nonaccrual ("nonperforming") status.
The majority of the Bank’s noncovered TDRs are a result of granting extensions to troubled credits which have already been adversely classified. The Bank grants 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. 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 noncovered 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 for noncovered TDRs using the same guidance as used for other noncovered impaired loans.
The recorded investment balance and related allowance for loan losses of noncovered performing and noncovered nonaccrual TDRs as of June 30, 2014 and December 31, 2013 were as follows:
	June 30, 2014								December 31, 2013

Allowance for loan losses on noncovered TDRs	2,202				342				2,957				191
The unfunded commitment to borrowers related to noncovered TDRs was $1.3 million and $4.5 million at June 30, 2014 and December 31, 2013, respectively.
Noncovered loans that were modified as TDRs during the three and six months ended June 30, 2014 and 2013 are set forth in the following table:

-1	Number of contracts and outstanding principal balance represent loans which have balances as of period end as certain loans may have been paid-down or charged-off during the three and six months ended June 30, 2014 and 2013.
-2	Includes subsequent payments after modifications and reflects the balance as of period end. 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 both the three and six months ended June 30, 2014, the Company's initial advance at the time of modification on these construction loans totaled $45,000 and the total commitment amount was $190,000. During both the three and six months ended June 30, 2013, the Company's initial advance at the time of modification on these construction loans totaled $324,000 and the total commitment amount was $1.3 million.
Of the nine noncovered loans modified during the three months ended June 30, 2014 and the 18 noncovered loans modified during the six months ended June 30, 2014, three loans with a total outstanding principal balance of $1.1 million had no prior modifications. The remaining noncovered loans included in the tables above for the three and six months ended June 30, 2014 were previously reported as noncovered TDRs. 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 noncovered 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 noncovered TDR and adjusted, as necessary, in the current periods based on more recent information. The related specific valuation allowance for noncovered loans that were modified as TDRs during the three and six months ended June 30, 2014 was $357,000 and $1.5 million, respectively, at June 30, 2014.
The noncovered loans modified during the previous twelve months ended June 30, 2014 that subsequently defaulted during the three and six months ended June 30, 2014 are included in the following table:
	Three and Six Months Ended June 30, 2014
	Number of			Outstanding
	Contracts			Principal Balance
	(Dollars in thousands)
Commercial business:
Commercial and industrial	3			$	790
Non-owner occupied commercial real estate	1			2
Total commercial business	4			792
Total noncovered loans receivable	4			$	792
All of the loans included in the above table defaulted because they were past their modified maturity date, and the borrower has not repaid the credit. The Bank does not intend to extend the maturity. The Bank had a specific valuation allowance of $160,000 related to these credits at June 30, 2014.
There were no loans modified during the previous twelve months ended June 30, 2013 that subsequently defaulted during the three and six months ended June 30, 2013.
(h) Noncovered Purchased Credit Impaired Loans
The Company acquired noncovered PCI loans from the May 1, 2014 Washington Banking Merger and from previously completed acquisitions which are accounted for under FASB ASC 310-30. These previous acquisitions include the FDIC-assisted acquisitions of Cowlitz Bank ("Cowlitz") and Pierce Commercial Bank ("Pierce") on July 30, 2010 and November 8, 2010, respectively. In addition, the Company completed the acquisitions of Northwest Commercial Bank ("NCB") on January 9, 2013 and the acquisition of Valley Community Bancshares, Inc. ("Valley") on July 15, 2013.
The following tables reflect the outstanding principal balance and recorded investment at June 30, 2014 and December 31, 2013 of the noncovered PCI loans:

Gross noncovered PCI loans	$	40,228			$	36,017
On the acquisition dates, the amount by which the undiscounted expected cash flows of the noncovered PCI 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 noncovered PCI loans.
The following tables summarize the accretable yield on the noncovered PCI loans resulting from the Pierce, NCB, Valley and Washington Banking acquisitions for the three and six months ended June 30, 2014 and 2013.
		Three Months Ended June 30,								Six Months Ended June 30,
		2014				2013				2014				2013

Balance at the end of the period		$	16,398			$	8,363			$	16,398			$	8,363
(1) Includes accretable difference at acquisition.
On the May 1, 2014 merger date for the Washington Banking Merger, the contractual cash flows on noncovered PCI loans acquired in the Washington Banking Merger were $75.1 million and the expected cash flows were $59.0 million, resulting in a $16.2 million non-accretable difference. The fair value was estimated at $48.8 million, resulting in a $10.2 million accretable yield which is included in the table above as a change in accretable yield for the three and six months ended June 30, 2014. The contractual cash flows on the noncovered non-PCI loans were $1.12 billion and the expected cash flows were $1.07 billion, resulting in $53.4 million of cash flows not expected to be collected. The fair value of the noncovered non-PCI loans at May 1, 2014 was $845.1 million.

	Covered Loans Receivable
	The Company acquired loans through FDIC-assisted transactions which are covered by FDIC shared-loss agreements. These loans are referred to as "covered loans." Covered loans were acquired with the Cowlitz Acquisition in July 2010. Covered loans were also acquired with the Washington Banking Merger in May 2014. Previously, Washington Banking had acquired loans from City Bank in April 2010 and North County Bank in September 2010. The shared-loss agreements with these acquisitions were transferred to Heritage Bank as part of the Washington Banking Merger.
	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 PCI 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.
	(a) Risk Management
	The Company categorizes covered loans in the same four segments as the noncovered portfolio: commercial business, real estate construction and land development, one-to-four family residential and consumer.

There was $75,000 in unfunded commitments related to credits classified as covered TDRs at June 30, 2014. There were no unfunded commitments related to the covered TDRs as of December 31, 2013.
There were no covered loans modified as TDRs during the three months ended June 30, 2014 and 2013 or during the six months ended June 30, 2013. During the six months ended June 30, 2014, the Bank modified one commercial and industrial loan with recorded investment balance of $3.6 million at June 30, 2014 . This loan was originally modified in the third quarter of 2013, and at that time the Bank provided for a shorter maturity date than it expected to receive the cash flows to more closely monitor the borrower. At June 30, 2014, this loan had a specific valuation allowance of $395,000.
There were no covered loans modified during the previous twelve months ended June 30, 2014 and June 30, 2013 that subsequently defaulted during the three and six months ended June 30, 2014 and 2013.
(g) Covered Purchased Credit Impaired Loans

The Bank has the option to modify certain covered PCI loans which may terminate the FDIC shared-loss coverage on those modified loans. At both June 30, 2014 and December 31, 2013, the recorded investment balance of covered PCI 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.
(h) Accretable Yield
The following table summarizes the accretable yield on the covered PCI loans resulting from the Cowlitz and Washington Banking transactions for the three and six months ended June 30, 2014 and 2013.

(1) Includes accretable difference at acquisition.
On the May 1, 2014 merger date of the Washington Banking Merger, the contractual cash flows on covered PCI loans acquired in the Washington Banking Merger were $72.1 million and the expected cash flows were $52.3 million, resulting in a $19.8 million non-accretable difference. The fair value was estimated at $48.8 million, resulting in a $3.5 million accretable yield which is included in the table above as a change in accretable yield for the three and six months ended June 30, 2014. The contractual cash flows on the noncovered non-PCI loans were $73.4 million and the expected cash flows were $69.5 million, resulting in $3.9 million of cash flows not expected to be collected. The fair value of the noncovered non-PCI loans at May 1, 2014 was $60.9 million.

	The covered loans acquired in the Cowlitz and Washington Banking (including Washington Banking's prior acquisitions of City Bank and North County Bank) transactions 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 Washington Banking on May 1, 2014, Valley Community Bancshares 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 additions of goodwill of $88.8 million during the three and six months ended June 30, 2014 as a result of the Washington Banking Merger. For additional information on the Washington Banking Merger, see "Note 2. Business Combination". There were no goodwill additions recorded during the three and six months ended June 30, 2013.
	At June 30, 2014, 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 three and six months ended June 30, 2014. The Company did not record goodwill impairment charges for the three and six months ended June 30, 2013. Even though there was no goodwill impairment at June 30, 2014, 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 operating results.
	b) Other Intangible Assets
	The other intangible assets represents the core deposit intangible ("CDI") acquired in business combinations. The useful life of the CDI related to the acquisitions of Washington Banking, Valley, NCB, Pierce, Cowlitz, and Western Washington Bancorp acquisitions were estimated to be ten, ten, five, four, nine, and eight years, respectively.
	The following table presents the change in the other intangible assets for the periods indicated:

	Potential dilutive shares are excluded from the computation of earnings per share if their effect is anti-dilutive. For the three and six months ended June 30, 2014, anti-dilutive shares outstanding related to options to acquire common stock totaled 23,204 and 32,940, respectively, as the assumed proceeds from exercise price, tax benefits and future compensation was in excess of the market value. For the three and six months ended June 30, 2013, anti-dilutive shares outstanding related to options to acquire common stock totaled 167,147 and 187,196, 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 source of income. The following table summarizes the dividend activity for the six months ended June 30, 2014 and 2013.
	Declared		Cash Dividend		Record Date		Paid Date
			per Share
	January 30, 2013		$0.08		February 8, 2013		February 22, 2013
	April 24, 2013		$0.08		May 10, 2013		May 24, 2013
	29-Jan-14		$0.08		February 10, 2014		February 24, 2014
	27-Mar-14		$0.08		April 8, 2014		April 23, 2014
	The FDIC and the Washington DFI have the authority under their supervisory powers to prohibit the payment of dividends by the Bank to the Company. Additionally, current guidance from the Board of Governors of the Federal Reserve System ("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 the 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.
	During the three and six months ended June 30, 2014 and 2013, the Company did not repurchase shares under the plan. In total, the Company has repurchased 596,900 shares at an average price of $15.70 per share under the tenth stock repurchase plan as of June 30, 2014.
	During the three and six months ended June 30, 2014, the Company repurchased 8,186 and 17,484 shares at an average price of $12.91 and $15.49 to pay withholding taxes on restricted stock that vested during the three and six months ended June 30, 2014, respectively. The Company repurchased 4,539 and 12,319 shares at an average price of $14.22 and $14.82 to pay withholding taxes on restricted stock that vested during the three and six months ended June 30, 2013, respectively.

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 values 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 June 30, 2014 and December 31, 2013.

	There were no transfers between Level 1 and Level 2 during the three and six months ended June 30, 2014 and 2013.
	The Company may be required to measure certain financial assets and liabilities at fair value on a nonrecurring basis. These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets.

(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).
Federal Home Loan Bank ("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 Held for Sale:
The fair value of loans held for sale is estimated based upon binding contracts or quotes from third party investors. (Level 2).
Loans Receivable:
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 produce 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).
Junior Subordinated Debentures:
The fair value is estimated using discounted cash flow analysis based on current rates for similar types of debt. At June 30, 2014, the fair value approximated the carrying value based on the valuation of the instrument completed at the Washington Banking Merger date (Level 3).
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.

Description of Business	'
	Description of Business
	Heritage Financial Corporation ("Heritage" or 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. The Bank is headquartered in Olympia, Washington and conducts business from its sixty-seven 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 primarily located in its market area.
	The Company has expanded its footprint through mergers and acquisitions beginning with its first acquisition in July 2010. The largest of these transactions was the strategic merger with Washington Banking Company (“Washington Banking”) and its wholly owned subsidiary bank, Whidbey Island Bank ("Whidbey") which was effective on May 1, 2014. The merger is referred to as the "Washington Banking Merger". The Washington Banking results since May 1, 2014 are included in this Quarterly Report on Form 10-Q. The strategic merger is described in more detail in "Note 2 - Business Combinations."
Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with Generally Accepted Accounting Principles (“GAAP”), for interim financial information, pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These Condensed Consolidated Financial Statements and accompanying Notes should be read with the Company's December 31, 2013 audited Consolidated Financial Statements and the accompanying Notes included in the Company's Annual Report on Form 10-K (“2013 Annual Form 10-K”). In management's opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. In preparing the Condensed Consolidated Financial Statements, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. Actual results could differ from those estimates. Estimates related to the allowance for loan losses, other than temporary impairments in the fair value of investment securities, expected cash flows of purchased credit impaired loans and related indemnification asset, fair value measurements, stock-based compensation, impairment of goodwill and other intangible assets and income taxes are particularly subject to change.
	Certain prior period amounts have been reclassified to conform to the current period’s presentation. Reclassifications had no effect on prior periods' net income or stockholders’ equity.
	As a result of the Washington Banking Merger, the Company reclassified its loan portfolio. Total loans receivable are now presented in two categories: noncovered loans receivable and covered loans receivable. A description of the categories is included below.
	Noncovered Loans Receivable: Noncovered loans are those that are not covered by FDIC shared-loss agreements and can include loans originated by the Company or acquired in mergers and acquisitions. Loans are stated at the unpaid principal balance, net of premiums, unearned discounts and net deferred loan origination fees and costs. The premiums and unearned discounts may include values determined in purchase accounting. The loans purchased in acquisitions included in this category include those accounted for under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, or those accounted for under ASC 310-20, Receivables - Nonrefundable fees and Other Costs.
	Covered Loans Receivable: Covered loans are those that are covered by FDIC shared-loss agreements. These include the majority of loans from the Company's acquisition of Cowlitz Bank, as well as loans from Washington Banking's acquisitions of City Bank and North County Bank, as then acquired by the Company in the Washington Banking Merger. The same accounting principles applicable to noncovered loans receivable apply to covered loans, with the added benefit of shared-loss agreements.
Significant Accounting Policies	'
	Significant Accounting Policies
	The significant accounting policies used in preparation of our Condensed Consolidated Financial Statements are disclosed in our 2013 Annual Form 10-K. There have not been any material changes in our significant accounting policies from those contained in our 2013 Annual Form 10-K. As a result of the Washington Banking Merger, the Company has added an additional significant accounting policy which is described below.
	Bank Owned Life Insurance: The Company acquired in the Washington Banking Merger fair value of $32.5 million in bank owned life insurance (“BOLI”). These policies insure the lives of certain current or former Whidbey officers, and name the Bank as beneficiary. Noninterest income is generated tax-free (subject to certain limitations) from the increase in the policies' underlying investments made by the insurance company.  The Bank is capitalizing on the ability to partially offset costs associated with employee compensation and benefit programs with the BOLI. BOLI is recorded at the amount that can be realized under the issuance contract at the statement of financial condition date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Recently Issued Accounting Pronouncements	'
	Recently Issued Accounting Pronouncements
	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. The adoption of this amendment did not have a material impact on the Company's Condensed Consolidated Financial Statements.
	FASB ASU No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects, was issued in January 2014.  The objective of this amendment is to provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit. The amendments in the standard permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The standard will be effective for the Company beginning January 1, 2015; however, early adoption is permitted. The Company is currently reviewing the provisions of this Update to determine the impacts it may have on the Company’s financial condition or results of operations.
	FASB ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure, was issued in January 2014. This Update intends to reduce diversity in practice by clarifying when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The amendment states that the real estate property should be recognized upon either the creditor obtaining legal title or the borrower convening all interest through a deed in lieu of foreclosure or similar legal agreement. These amendments are effective for interim and annual reporting periods beginning after December 15, 2014. Early adoption is permitted. The Company adopted the amendments in first quarter of 2014. The adoption did not have an impact on the Company's Condensed Consolidated Financial Statements.
	FASB ASU 2014-09, Revenue from Contracts with Customers, was issued in May 2014. Under this Update, FASB created a new Topic 606 which is in response to a joint initiative of FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. generally accepted accounting principles and international financial reporting standards that would:
	1	Remove inconsistencies and weaknesses in revenue requirements.
	2	Provide a more robust framework for addressing revenue issues.
	3	Improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets.
	4	Provide more useful information to users of financial statements through improved disclosure requirements.
	5	Simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer.
	The amendments in this Update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The Company is currently evaluating the impact this new accounting standard will have on its Condensed Consolidated Financial Statements.
	FASB ASU 2014-11, Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures, was issued in June 2014. This Update aligns the accounting for repurchase-to-maturity transactions and repurchase agreements executed as a repurchase financing with the accounting for other typical repurchase agreements, such as secured borrowings. The guidance eliminates sale accounting and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement. The amendments in this ASU require new and expanded disclosures. These amendments are effective for interim or annual reporting periods beginning after December 15, 2014. Early adoption for a public company is prohibited. The Company does not anticipate the adoption will have a material impact on its Condensed Consolidated Financial Statements.
Fair Value Measurements	'
	Loans Receivable:
	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 produce a higher value.

Unaudited pro forma information	'
	The following tables presents certain unaudited pro forma information, for illustrative purposes only, for the six month periods ended June 30, 2014 and 2013 as if Washington Banking had been acquired on January 1, 2013. The unaudited estimated pro forma information combines the historical results of Washington Banking with the Company's consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods. The pro forma information is not indicative of what would have occurred had the Washington Banking Merger occurred on January 1, 2013. In particular, no adjustments have been made to eliminate the impact of the Washington Banking loans which were previously accounted for under ASC 310-30 that may have been necessary had they been recorded at fair value at January 1, 2013. Additionally, Heritage expects to achieve further operating savings and other business synergies, including interest income growth, as a result of the Washington Banking Merger which are not reflective in the pro forma amounts that follow. As a result, actual amounts will differ from the unaudited pro forma information presented.

	(A)	Adjustment of interest income from loans due to the estimated amortization of the new interest rate mark and the accretion of the acquisition accounting adjustment relating to the credit mark. The Washington Banking credit and interest rate marks and accretion recorded during the six months ended June 30, 2014 and 2013 as a result of its prior acquisitions were not adjusted.
	(B)	Adjustments to reflect the amortization of the premium resulting from the fair value adjustment of the fixed rate maturities and the discount resulting from the fair value adjustment of the junior subordinated debentures.
	(C)	As acquired loans and leases are recorded at fair value, the Company would expect a reduction in the historical provision for loan and leases losses from legacy Washington Banking; however, no adjustment to the historical amount of Washington Banking's provision for loan and lease losses is reflected in these pro forma statements.
	(D)	Adjustment to reflect the amortization of the interest component of the fair value adjustment of the FDIC indemnification asset.
	(E)	In connection with the Washington Banking Merger, Heritage recognized $5.6 million of direct merger-related expenses for the six month period ended June 30, 2014, which were excluded in this adjustment. Also, adjustment reflects the decrease in the depreciation expense as a result of the fair value adjustment to the premises and equipment, which effectively increased non-depreciable assets and decreased depreciable assets. Adjustment additionally reflects the amortization of assumed liabilities included in the the fair value adjustment of accrued expenses and other liabilities.
	(F)	Income tax effect of pro forma adjustments at Company's statutory rate of 35%, excluding certain nondeductible costs included in the proforma adjustments.
	(G) Earnings per common share, basic and diluted, were calculated using the calculated pro forma net income less dividends and undistributed earnings allocated to participating securities divided by the calculated pro forma basic and diluted weighted average shares outstanding. Basic and diluted weighted average common shares outstanding for the six months ended June 30, 2014 and 2013 were calculated by adding the applicable weighted average of the 13,975,246 shares issued by Heritage in conjunction with the Washington Banking Merger to the historical weighted average Heritage shares outstanding for the six months ended June 30, 2014 and 2013, respectively.

[1]

Adjustment of interest income from loans due to the estimated amortization of the new interest rate mark and the accretion of the acquisition accounting adjustment relating to the credit mark. The Washington Banking credit and interest rate marks and accretion recorded during the six months ended June 30, 2014 and 2013 as a result of its prior acquisitions were not adjusted.

[2]

Adjustments to reflect the amortization of the premium resulting from the fair value adjustment of the fixed rate maturities and the discount resulting from the fair value adjustment of the junior subordinated debentures.

[3]

As acquired loans and leases are recorded at fair value, the Company would expect a reduction in the historical provision for loan and leases losses from legacy Washington Banking; however, no adjustment to the historical amount of Washington Banking's provision for loan and lease losses is reflected in these pro forma statements.

[4]

Adjustment to reflect the amortization of the interest component of the fair value adjustment of the FDIC indemnification asset.

[5]

In connection with the Washington Banking Merger, Heritage recognized $5.6 million of direct merger-related expenses for the six month period ended June 30, 2014, which were excluded in this adjustment. Also, adjustment reflects the decrease in the depreciation expense as a result of the fair value adjustment to the premises and equipment, which effectively increased non-depreciable assets and decreased depreciable assets. Adjustment additionally reflects the amortization of assumed liabilities included in the the fair value adjustment of accrued expenses and other liabilities.

[6]

Income tax effect of pro forma adjustments at Company's statutory rate of 35%, excluding certain nondeductible costs included in the proforma adjustments.

[7]

Earnings per common share, basic and diluted, were calculated using the calculated pro forma net income less dividends and undistributed earnings allocated to participating securities divided by the calculated pro forma basic and diluted weighted average shares outstanding. Basic and diluted weighted average common shares outstanding for the six months ended June 30, 2014 and 2013 were calculated by adding the applicable weighted average of the 13,975,246 shares issued by Heritage in conjunction with the Washington Banking Merger to the historical weighted average Heritage shares outstanding for the six months ended June 30, 2014 and 2013, respectively.

Number of contracts and outstanding principal balance represent loans which have balances as of period end as certain loans may have been paid-down or charged-off during the three and six months ended June 30, 2014 and 2013.

[2]

Includes subsequent payments after modifications and reflects the balance as of period end. 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 both the three and six months ended June 30, 2014, the Company's initial advance at the time of modification on these construction loans totaled $45,000 and the total commitment amount was $190,000. During both the three and six months ended June 30, 2013, the Company's initial advance at the time of modification on these construction loans totaled $324,000 and the total commitment amount was $1.3 million.
