	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. The Bank is headquartered in Olympia, Washington and conducts business from its thirty-six 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 ("Cowlitz"), 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 ("Pierce"), 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 on 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. The NCB Acquisition included two branches, and one of those branches was consolidated into an existing Heritage Bank location.
	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 and included eight branches, four of which were initially maintained by Heritage Bank following the completion of the transaction. At the time of the acquisition, one of the four branches, an owned branch building, was considered held for sale. During the fourth quarter of 2013, the leases for the remaining three leases were terminated by Heritage Bank.
	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 pursuant to which Heritage and Washington Banking will enter into a strategic merger with Washington Banking merging into Heritage, and immediately thereafter, Whidbey will merge with and into the Bank (the "Washington Banking Merger"). Washington Banking branches will adopt the Heritage Bank name in all markets, with the exception of six branches in the Whidbey Island markets that will continue to operate using the Whidbey Island Bank name. The corporate headquarters of the combined company will be in Olympia, Washington. The Washington Banking Merger is anticipated to be completed in the second quarter of 2014. See "Note 13 - Proposed Merger" for additional information.
	(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 our December 31, 2013 audited Consolidated Financial Statements and the accompanying Notes included in our Annual Report on Form 10-K (“2013 Annual Form 10-K”). In our opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 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, we are 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 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.
	(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.
	(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 Condensed Consolidated Financial Statements.
	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 Condensed Consolidated Financial Statements.

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 was 6.7% for both the three months ended March 31, 2014 and 2013, and the average prepayment rate for each period was 6.0%.
For the three months ended March 31, 2014, there were two private residential collateralized mortgage obligations determined to be other-than-temporarily impaired. All unrealized losses for the three months ended March 31, 2014 were deemed to be credit related, and the Company recorded the impairment in earnings. For the three months ended March 31, 2013, there was one private residential collateralized mortgage obligation determined to be other-than-temporarily impaired. The impairment for the three months ended March 31, 2013 was considered credit related and was recorded in earnings. No impairment for the three months ended March 31, 2014 and 2013 was recorded through other comprehensive income (loss). The following table summarizes activity for the three months ended March 31, 2014 and 2013 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”) activated 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 March 31, 2014 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 the second quarter of 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 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.

(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 March 31, 2014) non-owner occupied commercial real estate, commercial and industrial and owner-occupied commercial real estate. As of March 31, 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 originated loans receivable by credit quality indicator as of March 31, 2014 and December 31, 2013.

The tables above include $29.3 million and $27.4 million of originated impaired loans as of March 31, 2014 and December 31, 2013, respectively, as detailed in the impaired loans section below. These impaired loans have been individually reviewed for probable incurred losses and have a specific valuation allowance, as necessary. The tables above also include potential problem loans. 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. Potential problem originated loans as of March 31, 2014 and December 31, 2013 were $41.6 million and $34.5 million, respectively. The balance of potential problem originated loans guaranteed by a governmental agency, which reduces the Company's credit exposure, was $1.4 million and $1.8 million as of March 31, 2014 and December 31, 2013, respectively.
The following tables present the recorded invested balance of the purchased covered and non-covered loans receivable by credit quality indicator as of March 31, 2014 and December 31, 2013.

For the three months ended March 31, 2014 and 2013 no interest income was recognized subsequent to a loan’s classification as nonaccrual. For the three months ended March 31, 2014 and 2013, the Bank recorded $309,000 and $217,000 of interest income related to restructured performing loans, respectively.
(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 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. 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.
The recorded investment balance and related allowance for loan losses of accruing and non-accruing TDRs as of March 31, 2014 and December 31, 2013 were as follows:
	March 31, 2014								December 31, 2013

Purchased other TDRs	5,382				232				5,903				110
Allowance for loan losses on purchased other TDRs	1,035				185				1,430				57
The unfunded commitment to borrowers related to originated TDRs was $842,000 and $1.5 million at March 31, 2014 and December 31, 2013, respectively. There were $74,000 and $17,000 of unfunded commitments to borrowers related to the purchased other TDRs as of March 31, 2014 and December 31, 2013, respectively.
Originated loans that were modified as TDRs during the three months ended March 31, 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 months ended March 31, 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. There were no construction loans under a master guidance line that were modified as TDRs during the three months ended March 31, 2014 and 2013.
Of the 11 loans modified during the three months ended March 31, 2014, three loans with a total outstanding principal balance of $584,000 were previously reported as TDRs as of December 31, 2013. Of the 13 loans modified during the three months ended March 31, 2013, five loans with a total outstanding principal balance of $1.9 million were previously reported as TDRs as of December 31, 2012. 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 three months ended March 31, 2014 was $744,000 at March 31, 2014. The related specific valuation allowance for those TDRs that were previously reported as TDRs as of December 31, 2013 was $484,000 and the allowance for loan losses for TDRs that were modified during the three months ended March 31, 2014 that were not previously reported as TDRs was $6,000 as of December 31, 2013.
Purchased other loans that were modified as TDRs during the three months ended March 31, 2014 and 2013 are set forth in the following table:

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.
Of the four purchased other loans modified as TDRs during the three months ended March 31, 2014, the three commercial and industrial loans totaling $4.2 million were previously reported as TDRs at December 31, 2013. The Bank granted extensions of one year to two of the loans and required full payment of the third loan approximately two years before the original maturity date based on a revised loan agreement. The related specific valuation allowance for the purchased other loans modified as TDRs during the three months ended March 31, 2014 was $954,000 as of March 31, 2014.
The loans modified during the previous twelve months ended March 31, 2014 that subsequently defaulted during the three months ended March 31, 2014 are included in the following table:

There were no originated or purchased other loans that had been modified during the previous twelve months ended March 31, 2013 that subsequently defaulted during the three months ended March 31, 2013.
(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 March 31, 2014 and December 31, 2013 of the purchased impaired loans by acquisition:

The total balance of subsequent advances on the purchased impaired covered loans was $3.3 million and $2.6 million as of March 31, 2014 and December 31, 2013, 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 March 31, 2014 and December 31, 2013, 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.

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 three months ended March 31, 2014 and 2013. As the Valley Acquisition was not completed until third quarter of 2013, there are no balances for the three months ended March 31, 2013.

	Allowance for Loan Losses
	The allowance for loan losses is maintained at a level deemed appropriate by management to adequately provide for known and inherent risks in the loan portfolio. A summary of the changes in the originated loans’ allowance for loan losses for the three months ended March 31, 2014 and 2013 are as follows:
		Three Months Ended March 31,

	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.
	The following table details activity in the allowance for loan losses disaggregated on the basis of the Company’s impairment method as of and for the three months ended March 31, 2014:

Goodwill and Intangible Assets Disclosure [Abstract]	'

	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 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).
	There were no goodwill additions recorded during the three months ended March 31, 2014 and 2013.
	At March 31, 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 months ended March 31, 2014. The Company did not record goodwill impairment charges for the three months ended March 31, 2013. Even though there was no goodwill impairment at March 31, 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 Condensed Consolidated Financial Statements.
	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 Valley, NCB, Pierce, Cowlitz, and Western Washington Bancorp acquisitions is ten, five, four, nine, and eight years, respectively.
	There were no intangible asset additions recorded during the three months ended March 31, 2014. During the three months ended March 31, 2013, the Company recorded additions of intangible assets of $156,000 due to the NCB Acquisition.
	Amortization expense related to the core deposit intangibles was $156,000 and $115,000 for the three months ended March 31, 2014 and 2013, respectively.

	Potential dilutive shares are excluded from the computation of earnings per share if their effect is anti-dilutive. For the three months ended March 31, 2014 and 2013, anti-dilutive shares outstanding related to options to acquire common stock totaled 131,459 and 207,468, 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 three months ended March 31, 2014 and 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 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 months ended March 31, 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 March 31, 2014.
	During the three months ended March 31, 2014 and 2013, the Company repurchased 9,298 and 7,780 shares at an average price of $17.77 and $14.21 to pay withholding taxes on restricted stock that vested during the three months ended March 31, 2014 and 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 March 31, 2014 and December 31, 2013.

	There were no transfers between Level 1 and Level 2 during the three months ended March 31, 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.

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 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).
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.

Proposed Merger	'
	Proposed Merger
	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. Washington Banking branches will adopt 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 corporate headquarters of the combined company will be located in Olympia, Washington.
	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 $18.14 on March 4, 2014, the last practicable trading day before the printing of the joint proxy statement/prospectus, the value of the per share merger consideration payable to Washington Banking shareholders was $18.89, or approximately $296.7 million in the 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 December 31, 2013, Washington Banking had approximately $1.7 billion in total assets.
	The merger agreement has been unanimously approved by the boards of directors of Heritage and Washington Banking and their respective shareholder and the transaction has received all regulatory approvals. The closing of the merger is subject to certain other customary closing conditions. The merger is expected to close on May 1, 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 424(b)(3), the definitive joint proxy statement/prospectus filed by the Company with the SEC on March 14, 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. The Bank is headquartered in Olympia, Washington and conducts business from its thirty-six 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 ("Cowlitz"), 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 ("Pierce"), 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 on 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. The NCB Acquisition included two branches, and one of those branches was consolidated into an existing Heritage Bank location.
	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 and included eight branches, four of which were initially maintained by Heritage Bank following the completion of the transaction. At the time of the acquisition, one of the four branches, an owned branch building, was considered held for sale. During the fourth quarter of 2013, the leases for the remaining three leases were terminated by Heritage Bank.
	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 pursuant to which Heritage and Washington Banking will enter into a strategic merger with Washington Banking merging into Heritage, and immediately thereafter, Whidbey will merge with and into the Bank (the "Washington Banking Merger"). Washington Banking branches will adopt the Heritage Bank name in all markets, with the exception of six branches in the Whidbey Island markets that will continue to operate using the Whidbey Island Bank name. The corporate headquarters of the combined company will be in Olympia, Washington. The Washington Banking Merger is anticipated to be completed in the second quarter of 2014. See "Note 13 - Proposed Merger" for additional information.
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 our December 31, 2013 audited Consolidated Financial Statements and the accompanying Notes included in our Annual Report on Form 10-K (“2013 Annual Form 10-K”). In our opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 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, we are 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 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.
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.
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 Condensed Consolidated Financial Statements.
	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 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.

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 March 31, 2014 and December 31, 2013, 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.
