Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Consolidation	BASIS OF PRESENTATION AND CONSOLIDATION Conversion Blue Hills Bancorp, Inc. (the “Company”) is a Maryland corporation formed in February 2014 for the purpose of becoming the holding company for Blue Hills Bank (the “Bank”) concurrent with the conversion of Hyde Park Bancorp, MHC from the mutual holding company to the stock holding company form of organization on July 21, 2014. In connection with the conversion, the Bank became a wholly-owned subsidiary of the Company and the Company sold 27,772,500 shares of its common stock, representing the adjusted maximum of the offering range, at $10.00 per share, for gross offering proceeds of approximately $277,725,000 , including the sale of 2,277,345 shares to the employee stock ownership plan (“ESOP”) for $22,773,450 . The purchase of common stock by the ESOP was financed by a loan from Blue Hills Funding Corporation, a subsidiary of the Company. Upon the completion of the conversion, Hyde Park Bancorp, MHC and the Bank’s former Massachusetts chartered mid-tier holding company, Hyde Park Bancorp, Inc., ceased to exist. In connection with the plan of conversion, the Company established the Blue Hills Bank Foundation (the “Foundation”). The Foundation was funded with $7.0 million , including 694,313 shares of the Company’s common stock and $57,000 in cash, which was recorded as an expense by the Company in July 2014. The Company anticipates the contribution will be deductible for federal income tax purposes. Basis of Presentation The accompanying unaudited interim consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Blue Hills Funding Corporation and the Bank, the principal operating entity, and the Bank's wholly-owned subsidiaries, HP Security Corporation and B.H. Security Corporation, which are Massachusetts security corporations, and 1196 Corporation, which holds a restricted stock. All significant intercompany balances and transactions have been eliminated in consolidation. The unaudited consolidated financial statements of the Company presented herein have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information and pursuant to the rules of the Securities and Exchange Commission ("SEC") for quarterly reports on Form 10-Q and Article 8 of Regulation S-X and do not include all of the information and note disclosures required by GAAP for a complete set of financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures necessary for the fair presentation of the accompanying consolidated financial statements have been included. Interim results are not necessarily reflective of the results of the year. The accompanying unaudited financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2014, included in the Company's annual report on Form 10-K. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and the realizability of deferred tax assets. Reclassification Certain amounts in the December 31, 2014 consolidated financial statements have been reclassified to conform to the current presentation. Loan policies Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for the allowance for loan losses, charge-offs and any deferred fees and costs on originated and purchased loans. Interest income is accrued on the unpaid principal balance. Deferred loan origination fees/costs and discounts on purchased loans are recognized as an adjustment of the related loan yield using the interest method. It is the policy of the Company to discontinue the accrual of interest on loans past due in excess of 90 days, unless the loan is well-secured and in the process of collection, or when in the judgment of management, the ultimate collectability of the principal or interest becomes doubtful and to reverse all interest previously accrued against interest income. Past due status is based on contractual terms of the loan. The interest on non-accrual loans is accounted for on the cash-basis or cost recovery method until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due have been current for six consecutive months and future payments are reasonably assured. Allowance for loan losses The allowance for loan losses is based on the size and the composition of the loan portfolio, delinquency levels, loss experience, economic conditions and other factors related to the collectability of the loan portfolio. For portfolios for which the Company had no prior loss experience, the national and state peer group losses for relevant portfolios generally over the years 2006-2014 were used. Charge-off factors are updated at least annually and management assesses them quantitatively on a quarterly basis. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated regularly by management and reflects consideration of all significant factors that affect the collectability of the loan portfolio. The evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available; however, because of the increase in risk exposures new to the Company, it is the intention of management to maintain an allowance that is prudently commensurate with the growth in the loan portfolio. The allowance consists of general, allocated and unallocated components, as further described below. General component The general component of the allowance for loan losses is based on extrapolated historical loss experience for periods ranging from 2006-2014, adjusted for qualitative and environmental factors including levels/trends in delinquencies; trends in volumes and terms of loans; effects of changes in risk selection and underwriting standards and other changes in lending policies, procedures and practices; experience/ability/depth of lending management and staff; and national and local economic trends and conditions. The qualitative factors are determined based on the various risk characteristics of each loan segment. Risk characteristics relevant to each portfolio segment are as follows: Residential real estate - The Company does not generally originate loans with a loan-to-value ratio greater than 80 percent and does not generally grant loans that would be classified as subprime upon origination. When the Company does extend credit either on a first- or second-lien basis at a loan-to-value ratio greater than 80 percent , such loans are supported by either mortgage insurance or state guarantee programs. All loans in this segment are collateralized by owner-occupied, 1-4 family residential real estate and repayment is dependent on the credit quality of the individual borrower. The health of the regional economy, including unemployment rates and housing prices, will have an effect on the credit quality of loans in this segment. Home equity - Loans in this segment are generally secured by 1 st or 2 nd liens on residential real estate. Repayment is dependent on the credit quality of the individual borrower. The Company evaluates each loan application based on factors including the borrower’s credit score, income, length of employment, and other factors to establish the creditworthiness of the borrower. Commercial real estate - Loans in this segment include investment real estate and are generally secured by assignments of leases and real estate collateral. In cases where there is a concentration of exposure to a single large tenant, underwriting standards include analysis of the tenant’s ability to support lease payments over the duration of the loan. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy as evidenced by increased vacancy rates, which in turn, will have an effect on the credit quality in this segment. Payments on loans secured by income-producing properties often depend on the successful operation and management of the properties. Management continually monitors the cash flows of these loans. Construction - Loans in this segment primarily include real estate development loans for which payment is derived from permanent financing or sale of the property. Credit risk is affected by cost overruns, time to sell at an adequate price, and market conditions. Commercial business - Loans in this segment are generally secured by business assets, including accounts receivable, inventory, real estate and intangible assets. Strict underwriting standards include considerations of the borrower’s ability to support the debt service requirements from the underlying historical and projected cash flows of the business, collateral values, the borrower’s credit history and the ultimate collectability of the de bt. Economic conditions, real estate values, commodity prices, unemployment trends and other factors will affect the credit quality of loans in these segments. Consumer - Loans in this segment primarily include used auto loans. A significant portion of the used auto loan portfolio is comprised of geographically diverse loans originated by and purchased from a third party, who also provides collection services. While this portfolio has generated minimal charge-offs, the provisions for loan losses reflect management’s estimate of inherent losses based on a review of regional and national historical losses of other institutions with similar portfolios. Allocated component The allocated component relates to loans that are on the watch list (partially charged-off, non-accruing loans and accruing adversely-rated loans) or are considered impaired. Impairment is measured by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. An allowance is established when the discounted cash flows (or collateral value) of the impaired loan is lower than the carrying value of that loan. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Management reviews all loan types for individual impairment. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The Company periodically may agree to modify the contractual terms of loans. When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a troubled debt restructuring (“TDR”). All TDRs are initially classified as impaired and generally remain impaired for the remaining life of the loan. The impaired classification may be removed if the borrower demonstrates compliance with the modified terms and the restructuring agreement specifies an interest rate greater than or equal to that which would be provided to a borrower with similar credit risk at the time of restructuring. Unallocated component An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating allocated and general reserves in the portfolio.

The term “other-than-temporary” is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value is not necessarily favorable, or that there is a lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. Information pertaining to securities available for sale with gross unrealized losses aggregated by investment category and length of time that individual securities have been in a continuous loss position, follows: Less Than Twelve Months More Than Twelve Months Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value (In thousands) June 30, 2015 Debt securities: Government-sponsored enterprises $ (71 ) $ 15,012 $ — $ — Government-sponsored mortgage-backed and collateralized mortgage obligations (622 ) 116,275 (9 ) 225 Other mortgage- and asset-backed securities: Privately issued commercial mortgage- backed securities (34 ) 6,696 (73 ) 7,642 SBA asset-backed securities (15 ) 5,223 — — Other asset-backed securities (113 ) 8,214 — — Total other mortgage- and asset-backed securities (162 ) 20,133 (73 ) 7,642 State and political subdivisions (22 ) 2,380 — — Financial services: Banks (65 ) 11,502 — — Diversified financials (94 ) 6,914 — — Insurance and REITs (231 ) 10,385 — — Total financial services (390 ) 28,801 — — Other corporate: Industrials (577 ) 32,676 — — Utilities (442 ) 20,861 — — Total other corporate (1,019 ) 53,537 — — Total debt securities (2,286 ) 236,138 (82 ) 7,867 Marketable equity securities: Mutual funds: Domestic community — — (9 ) 457 Global asset allocation (18 ) 3,982 — — Total marketable equity securities (18 ) 3,982 (9 ) 457 Total temporarily impaired securities $ (2,304 ) $ 240,120 $ (91 ) $ 8,324 At June 30, 2015 , multiple debt securities have unrealized losses with aggregate depreciation of less than 1% from the Company’s amortized cost basis. The unrealized losses were primarily caused by interest rate fluctuations. A significant portion of these investments are guaranteed by U.S. Government-sponsored enterprises. It is expected that none of these securities would be settled at a price less than the par value of the investment. Because the decline in market value is attributable to changes in interest rates and not to credit quality, and because the Company does not intend to sell the securities and it is more likely than not that the Company will not be required to sell the securities before recovery of their amortized cost bases, which may be maturity, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2015 . At June 30, 2015 , the Company had two mutual funds with an unrealized loss of $27,000 , or less than 1% depreciation from the Company’s cost basis. No issues have been identified that cause management to believe the declines in market value are other than temporary and the Company has the ability and intent to hold these investments until a recovery of fair value.

Credit Quality Information The Company utilizes a ten-grade internal loan rating system for all loans as follows: Loans rated 1 – 6 are considered “acceptable” rated loans that are performing as agreed, and generally require only routine supervision. Loans rated 7 are considered “special mention.” These loans are starting to show signs of potential weakness and are being closely monitored by management. Loans rated 8 are considered “substandard.” Generally, a loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected. Generally, all loans 90 days delinquent are rated 8. Loans rated 9 are considered “doubtful.” Serious problems exist to the point where a partial loss of principal is likely. Weakness is so pronounced that on the basis of current information, conditions and values, collection in full is highly improbable. Loans rated 10 are considered "loss" and the credit extended to the customer is considered uncollectible or of such little value that it does not warrant consideration as an active asset. The Company assigns a 6 risk-rating to otherwise performing, satisfactorily collateralized Consumer and Residential loans where the Bank becomes aware of deterioration in a FICO score or other indication of potential inability to service the debt. The Company assigns risk ratings of 7-10 to residential or consumer loans that have a well-defined weakness that may jeopardize the collection of the contractual principal and interest, are contractually past due 90 days or more or legal action has commenced against the borrower. All other residential mortgage and consumer loans have no risk rating. On an annual basis, or more often if needed, the Company formally reviews the ratings on all commercial and construction loans. At least annually, the Company engages an independent third party to review a significant portion of loans within these segments. Management uses the results of these reviews as part of its annual review process. In addition, management utilizes delinquency reports, the watch list and other loan reports to monitor credit quality of other loan segments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Interest Rate Swap Agreements	INTEREST RATE SWAP AGREEMENTS The Company is party to derivative financial instruments in the normal course of business to manage exposure to fluctuations in interest rates and to meet the needs of commercial customers. These financial instruments have been generally limited to loan level interest rate swap agreements, which are entered into with counterparties that meet established credit standards. These transactions involve both credit and market risk. The notional amounts are amounts on which calculations, payments, and the value of the derivatives are based. Notional amounts do not represent direct credit exposures. The fair value of the derivative instruments is reflected on the Company’s consolidated balance sheet as other assets or accrued expenses and other liabilities as appropriate. Changes in the fair value of these agreements are recorded in miscellaneous income in the consolidated statements of operations. The Company did not have derivative fair value hedges or derivative cash flow hedges at June 30, 2015 and December 31, 2014 . The table below presents information about derivative financial instruments not designated as hedging instruments at June 30, 2015 and December 31, 2014 .

The Company controls the credit risk of its financial contracts through credit approvals, limits and monitoring procedures, and does not expect any counterparties to fail their obligations. The Company has minimum collateral posting thresholds with certain of its interest rate swap derivative counterparties. Other contracts represent risk participation agreements on commercial loan level interest rate swap agreements. The Company has entered into risk participation agreements with the correspondent institutions to share in any interest rate swap gains or losses incurred as a result of the commercial loan customers’ termination of a loan level interest rate swap agreement prior to maturity. The Company records these risk participation agreements at fair value.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASURMENTS Determination of fair value The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The following methods and assumptions were used by the Company in estimating fair value disclosures for financial instruments: Cash and cash equivalents : The carrying amounts of cash and due from banks and short-term investments approximate fair value. Securities available for sale : All fair value measurements are obtained from a third-party pricing service and are not adjusted by management. The securities measured at fair value in Level 1 are based on quoted market prices in an active exchange market. These securities include U.S. Treasuries and marketable equity securities. All other securities are measured at fair value in Level 2 based on pricing models that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes, credit spreads and new issue data. Federal Home Loan Bank stock : The carrying value of Federal Home Loan Bank stock approximates fair value based on the redemption provisions of the Federal Home Loan Bank. Loans : For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values for other types of loans are estimated using discounted cash flow analyses, using market interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values for non-performing loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable. Loans held for sale : Fair values are based on commitments in effect from investors or prevailing market prices. Accrued interest receivable : The carrying amount of accrued interest receivable approximates fair value. Deposits : The fair values for non-certificate accounts are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for certificate accounts are estimated using a discounted cash flow calculation that applies market interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. Borrowings : The carrying value of short-term borrowings approximates fair value based on the short-term nature of the instruments. The fair values of long-term debt are estimated using discounted cash flow analyses based on the current incremental borrowing rates in the market for similar types of borrowing arrangements. Derivative instruments : The fair values of interest rate swap agreements are based on a valuation model that uses primarily observable inputs, such as benchmark yield curves and interest rates and also include the value associated with counterparty credit risk. Off-balance sheet instruments : Fair values for off-balance sheet lending commitments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The estimated fair value of off-balance sheet financial instruments at June 30, 2015 and December 31, 2014 , was immaterial since fees charged are not material. Assets and liabilities measured at fair value on a recurring basis Assets and liabilities measured at fair value on a recurring basis are summarized below: Level 1 Level 2 Level 3 Total Fair Value (In thousands) June 30, 2015 Assets Securities available for sale: Debt securities $ 657 $ 383,153 $ — $ 383,810 Marketable equity securities 48,017 — — 48,017 Derivative assets — 6,172 — 6,172 Total assets $ 48,674 $ 389,325 $ — $ 437,999 Liabilities Derivative liabilities $ — $ 6,694 $ — $ 6,694 December 31, 2014 Assets Securities available for sale: Debt securities $ 13,219 $ 359,930 $ — $ 373,149 Marketable equity securities 43,298 — — 43,298 Derivative assets — 5,454 — 5,454 Total assets $ 56,517 $ 365,384 $ — $ 421,901 Liabilities Derivative liabilities $ — $ 5,842 $ — $ 5,842 Assets measured at fair value on a non-recurring basis The Company may also be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with generally accepted accounting principles. These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets. At June 30, 2015 , there are no assets measured at fair value on a non-recurring basis. At June 30, 2014, there was one impaired loan measured at fair value on a non-recurring basis using level 3 inputs, in the amount of $120,000 , with losses on this loan for the three and six months ended June 30, 2014 amounting to $18,000 . At June 30, 2015 and December 31, 2014 there were no liabilities measured at fair value on a non-recurring basis. Losses applicable to impaired loans are based on the appraised value of the underlying collateral, discounted as necessary due to management’s estimates of changes in market conditions. The losses applicable to impaired loans are not recorded as a direct adjustment to current earnings or comprehensive income, but rather as a component in determining the overall adequacy of the allowance for loan losses. Adjustments to the estimated fair value of impaired loans may result in increases or decreases to the provision for loan losses.

Stockholders' Equity

Equity [Abstract]
Stockholders' Equity	EQUITY Minimum regulatory capital requirements The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the Bank’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies. Quantitative measures established by regulation to ensure capital adequacy require minimum ratios of Tier 1 capital to average assets (Leverage Ratio) and common equity Tier 1, Tier 1 and Total capital to risk-weighted assets. These capital guidelines assign risk weights to on- and off-balance sheet items in arriving at total risk-weighted assets. Minimum capital levels are based upon the perceived risk of various asset categories and certain off-balance sheet instruments. In July 2013, federal banking regulators approved final rules that implement changes to the regulatory capital framework for U.S. banks. The rules set minimum requirements for both the quantity and quality of capital held by community banking institutions. The final rule includes a new minimum ratio of common equity Tier 1 capital to risk weighted assets of 4.5% , raises the minimum ratio of Tier 1 capital to risk-weighted assets from 4% to 6% and includes a minimum leverage ratio of 4% for all banking organizations. Additionally, community banking institutions must maintain a capital conservation buffer of common equity Tier 1 capital in an amount greater than 2.5% of total risk-weighted assets to avoid being subject to limitations on capital distributions and discretionary bonus payments to executive officers. The phase-in period for the rules began for the Company on January 1, 2015, with full compliance with all of the final rule’s requirements phased in over a multi-year schedule. The final rules also apply, effective January 1, 2015, consolidated capital requirements to the Company that are not less stringent than those applicable to the Bank. As of June 30, 2015 , the most recent notification from the Federal Deposit Insurance Corporation categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized an institution must maintain minimum total risk-based, Tier 1 risk-based, Common Equity Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Bank’s and the Company’s actual and minimum required capital amounts and ratios as of June 30, 2015 and December 31, 2014 are presented below.

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS On July 31, 2015, approximately $196.3 million of securities available for sale, with unrealized gains of $666,000 , were transfered to held to maturity designation. Held to maturity investments are investments that management has the positive intent and ability to hold to maturity. If a security is transferred from available for sale to held to maturity, the fair value at the time of transfer becomes the held-to-maturity security’s new cost basis. The unrealized holding gain at the transfer date continues to be reported in other comprehensive income and is amortized over the investments remaining life as an adjustment of yield in a manner similar to a premium or discount.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Loans Policy	Loan policies Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for the allowance for loan losses, charge-offs and any deferred fees and costs on originated and purchased loans. Interest income is accrued on the unpaid principal balance. Deferred loan origination fees/costs and discounts on purchased loans are recognized as an adjustment of the related loan yield using the interest method. It is the policy of the Company to discontinue the accrual of interest on loans past due in excess of 90 days, unless the loan is well-secured and in the process of collection, or when in the judgment of management, the ultimate collectability of the principal or interest becomes doubtful and to reverse all interest previously accrued against interest income. Past due status is based on contractual terms of the loan. The interest on non-accrual loans is accounted for on the cash-basis or cost recovery method until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due have been current for six consecutive months and future payments are reasonably assured.
Allowance for Loan Losses Policy	Allowance for loan losses The allowance for loan losses is based on the size and the composition of the loan portfolio, delinquency levels, loss experience, economic conditions and other factors related to the collectability of the loan portfolio. For portfolios for which the Company had no prior loss experience, the national and state peer group losses for relevant portfolios generally over the years 2006-2014 were used. Charge-off factors are updated at least annually and management assesses them quantitatively on a quarterly basis. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated regularly by management and reflects consideration of all significant factors that affect the collectability of the loan portfolio. The evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available; however, because of the increase in risk exposures new to the Company, it is the intention of management to maintain an allowance that is prudently commensurate with the growth in the loan portfolio. The allowance consists of general, allocated and unallocated components, as further described below. General component The general component of the allowance for loan losses is based on extrapolated historical loss experience for periods ranging from 2006-2014, adjusted for qualitative and environmental factors including levels/trends in delinquencies; trends in volumes and terms of loans; effects of changes in risk selection and underwriting standards and other changes in lending policies, procedures and practices; experience/ability/depth of lending management and staff; and national and local economic trends and conditions. The qualitative factors are determined based on the various risk characteristics of each loan segment. Risk characteristics relevant to each portfolio segment are as follows: Residential real estate - The Company does not generally originate loans with a loan-to-value ratio greater than 80 percent and does not generally grant loans that would be classified as subprime upon origination. When the Company does extend credit either on a first- or second-lien basis at a loan-to-value ratio greater than 80 percent , such loans are supported by either mortgage insurance or state guarantee programs. All loans in this segment are collateralized by owner-occupied, 1-4 family residential real estate and repayment is dependent on the credit quality of the individual borrower. The health of the regional economy, including unemployment rates and housing prices, will have an effect on the credit quality of loans in this segment. Home equity - Loans in this segment are generally secured by 1 st or 2 nd liens on residential real estate. Repayment is dependent on the credit quality of the individual borrower. The Company evaluates each loan application based on factors including the borrower’s credit score, income, length of employment, and other factors to establish the creditworthiness of the borrower. Commercial real estate - Loans in this segment include investment real estate and are generally secured by assignments of leases and real estate collateral. In cases where there is a concentration of exposure to a single large tenant, underwriting standards include analysis of the tenant’s ability to support lease payments over the duration of the loan. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy as evidenced by increased vacancy rates, which in turn, will have an effect on the credit quality in this segment. Payments on loans secured by income-producing properties often depend on the successful operation and management of the properties. Management continually monitors the cash flows of these loans. Construction - Loans in this segment primarily include real estate development loans for which payment is derived from permanent financing or sale of the property. Credit risk is affected by cost overruns, time to sell at an adequate price, and market conditions. Commercial business - Loans in this segment are generally secured by business assets, including accounts receivable, inventory, real estate and intangible assets. Strict underwriting standards include considerations of the borrower’s ability to support the debt service requirements from the underlying historical and projected cash flows of the business, collateral values, the borrower’s credit history and the ultimate collectability of the de bt. Economic conditions, real estate values, commodity prices, unemployment trends and other factors will affect the credit quality of loans in these segments. Consumer - Loans in this segment primarily include used auto loans. A significant portion of the used auto loan portfolio is comprised of geographically diverse loans originated by and purchased from a third party, who also provides collection services. While this portfolio has generated minimal charge-offs, the provisions for loan losses reflect management’s estimate of inherent losses based on a review of regional and national historical losses of other institutions with similar portfolios. Allocated component The allocated component relates to loans that are on the watch list (partially charged-off, non-accruing loans and accruing adversely-rated loans) or are considered impaired. Impairment is measured by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. An allowance is established when the discounted cash flows (or collateral value) of the impaired loan is lower than the carrying value of that loan. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Management reviews all loan types for individual impairment. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The Company periodically may agree to modify the contractual terms of loans. When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a troubled debt restructuring (“TDR”). All TDRs are initially classified as impaired and generally remain impaired for the remaining life of the loan. The impaired classification may be removed if the borrower demonstrates compliance with the modified terms and the restructuring agreement specifies an interest rate greater than or equal to that which would be provided to a borrower with similar credit risk at the time of restructuring. Unallocated component An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating allocated and general reserves in the portfolio.

The unrealized losses were primarily caused by interest rate fluctuations. A significant portion of these investments are guaranteed by U.S. Government-sponsored enterprises. It is expected that none of these securities would be settled at a price less than the par value of the investment. Because the decline in market value is attributable to changes in interest rates and not to credit quality, and because the Company does not intend to sell the securities and it is more likely than not that the Company will not be required to sell the securities before recovery of their amortized cost bases, which may be maturity, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2015 . At June 30, 2015 , the Company had two mutual funds with an unrealized loss of $27,000 , or less than 1% depreciation from the Company’s cost basis. No issues have been identified that cause management to believe the declines in market value are other than temporary and the Company has the ability and intent to hold these investments until a recovery of fair value.
