	(1)   Organization
	On November 4, 2008, the Board of Directors of Territorial Mutual Holding Company (MHC) approved a plan of conversion and reorganization under which MHC would convert from a mutual holding company to a stock holding company.  The conversion to a stock holding company was approved by the depositors and borrowers of Territorial Savings Bank and the Office of Thrift Supervision (OTS) and included the filing of a registration statement with the U.S. Securities and Exchange Commission.  Upon the completion of the conversion and reorganization on July 10, 2009, Territorial Mutual Holding Company and Territorial Savings Group, Inc. ceased to exist as separate legal entities and Territorial Bancorp Inc. became the holding company for Territorial Savings Bank. A total of 12,233,125 shares were issued in the conversion at $10 per share, raising $122.3 million of gross proceeds.  Approximately $3.7 million of conversion expenses were offset against the gross proceeds.  Territorial Bancorp Inc.’s common stock began trading on the NASDAQ Global Select Market under the symbol “TBNK” on July 13, 2009.
	Upon completion of the conversion and reorganization, a special “liquidation account” was established in an amount equal to the total equity of Territorial Mutual Holding Company as of December 31, 2008.  The liquidation account is to provide eligible account holders and supplemental eligible account holders who maintain their deposit accounts with Territorial Savings Bank after the conversion with a liquidation interest in the unlikely event of the complete liquidation of Territorial Savings Bank after the conversion.  The liquidation account will be reduced annually to the extent that eligible account holders and supplemental eligible account holders have reduced their qualifying deposits.  Subsequent increases will not restore an eligible account holder’s or supplemental eligible account holder’s interest in the liquidation account.  In the event of a complete liquidation of Territorial Savings Bank, and only in such event, each account holder will be entitled to receive a distribution from the liquidation account in an amount proportionate to the adjusted qualifying account balances then held.  The balance of the liquidation account at December 31, 2013 was $17.6 million.

	(2)   Summary of Significant Accounting Policies
	(a)                      Description of Business
	Territorial Bancorp Inc. (the “Company”), through its wholly-owned subsidiary, Territorial Savings Bank (the “Bank”), provides loan and deposit products and services primarily to individual customers through 28 branches located throughout Hawaii. We deal primarily in residential mortgage loans in the State of Hawaii.  The Company’s earnings depend primarily on its net interest income, which is the difference between the interest income earned on interest-earning assets (loans receivable and investments) and the interest expense incurred on interest-bearing liabilities (deposit liabilities and borrowings). Deposits traditionally have been the principal source of the Bank’s funds for use in lending, meeting liquidity requirements, and making investments. The Company also derives funds from receipt of interest and principal on outstanding loans receivable and investments, borrowings from the Federal Home Loan Bank (FHLB) of Seattle, securities sold under agreements to repurchase, and proceeds from issuance of common stock.
	(b)                      Principles of Consolidation
	The consolidated financial statements include the accounts and results of operations of Territorial Bancorp Inc. and its wholly owned subsidiaries, Territorial Savings Bank, Territorial Real Estate Co., Inc., and Territorial Financial Services, Inc. Significant intercompany balances and transactions have been eliminated in consolidation.
	(c)                       Cash and Cash Equivalents
	Cash and cash equivalents includes cash and due from banks, interest-bearing deposits in other banks, federal funds sold, and short-term, highly liquid investments with original maturities of three months or less.
	(d)                      Investment Securities
	The Company classifies and accounts for its investment securities as follows: (1) held-to-maturity debt securities in which the Company has the positive intent and ability to hold to maturity are reported at amortized cost; (2) trading securities that are purchased for the purpose of selling in the near term are reported at fair value, with unrealized gains and losses included in current earnings; and (3) available-for-sale securities not classified as either held-to-maturity or trading securities are reported at fair value, with unrealized gains and losses excluded from current earnings and reported as a separate component of equity. At December 31, 2013 and 2012, the Company classified all of its investments as held-to-maturity.
	A decline in the market value of any available-for-sale or held-to-maturity security below cost, that is deemed to be other than temporary, results in an impairment to reduce the carrying amount to fair value. To determine whether impairment is other than temporary, the Company considers whether it has the intent and ability not to sell and would not be required to sell for a sufficient period of time to recover the remaining amortized cost basis.
	Gains or losses on the sale of investment securities are computed using the specific-identification method. The Company amortizes premiums and accretes discounts associated with investment securities using the interest method over the contractual life of the respective investment security. Such amortization and accretion is included in the interest and dividend income line item in the consolidated statements of income. Dividend and interest income are recognized when earned.
	(e)                       Loans Receivable
	This policy applies to all loan classes.  Loans receivable are stated at the principal amount outstanding, less the allowance for loan losses, loan origination fees and costs, and commitment fees. Interest on loans receivable is accrued as earned. The Company has a policy of placing loans on a nonaccrual basis when more than 90 days contractually delinquent or when, in the opinion of management, collection of all or part of the principal balance appears doubtful. For nonaccrual loans, the Company records payments received as a reduction in principal. The Company, considering current information and events regarding the borrowers’ ability to repay their obligations, considers a loan to be impaired when it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. When a loan is considered to be impaired, the amount of the impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, if the loan is considered to be collateral dependent, based on the fair value of the collateral less estimated costs to sell.  Impairment losses are written off against the allowance for loan losses. For impaired loans, the Company records payments received as a reduction in principal. A nonaccrual loan may be restored to an accrual basis when principal and interest payments are current and full payment of principal and interest is expected.
	(f)                         Loans Held for Sale
	Loans held for sale are stated at the lower of aggregate cost or market value. Net fees and costs of originating loans held for sale are deferred and are included in the basis for determining the gain or loss on sales of loans held for sale.
	(g)                      Deferred Loan Origination Fees and Unearned Loan Discounts
	Loan origination and commitment fees and certain direct loan origination costs are being deferred, and the net amount is recognized over the life of the related loan as an adjustment to yield. Net deferred loan fees are amortized using the interest method over the contractual term of the loan, adjusted for actual prepayments. Net unamortized fees on loans paid in full are recognized as a component of interest income.
	(h)                      Real Estate Owned
	Real estate owned is valued at the time of foreclosure at fair value, less estimated cost to sell, thereby establishing a new cost basis. The Company obtains appraisals based on recent comparable sales to assist management in estimating the fair value of real estate owned. Subsequent to acquisition, real estate owned is valued at the lower of cost or fair value, less estimated cost to sell. Declines in value are charged to expense through a direct writedown of the asset. Costs related to holding real estate are charged to expense while costs related to development and improvements are capitalized.
	Profits from the sale of real estate are recognized when title has passed, minimum down payment requirements are met, the terms of any notes received are such as to satisfy continuing investment requirements, and the Company is relieved of any requirements for continued involvement with the properties. If the minimum down payment or the continuing investment is not adequate to meet the criteria specified in the Property, Plant and Equipment topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC), the Company will defer income recognition and account for such sales using alternative methods, such as installment, deposit, or cost recovery.
	(i)                         Allowance for Loan Losses
	The Company’s allowance for loan losses is maintained at a level considered adequate to provide for losses that can be estimated based upon specific and general conditions. All loan losses are charged, and all recoveries are credited, to the allowance for loan losses. Additions to the allowance for loan losses are provided by charges to income based on various factors, which, in the Company’s judgment, deserve current recognition in estimating probable losses. Charge-offs to the allowance are made when management determines that collectability of all or a portion of a loan is doubtful and available collateral is insufficient to repay the loan.
	General allowances are established for loan losses on a portfolio basis for loans that do not meet the definition of impaired, in accordance with the Receivables topic of the FASB ASC.  The portfolio is grouped into similar risk characteristics, primarily loan type and delinquency status. The Company applies an estimated loss rate to each loan group. The loss rates applied are based upon its loss experience adjusted, as appropriate, for environmental factors discussed below. This evaluation is inherently subjective, as it requires material estimates that may be susceptible to significant revisions based upon changes in economic and real estate market conditions.  Actual loan losses may be significantly more than the allowance for loan losses the Company has established, which could have a material negative effect on its financial results.
	Residential mortgage loans represent the largest segment of the Company’s loan portfolio.  All of the residential mortgage loans are secured by a first mortgage on residential real estate in Hawaii and consist primarily of fixed-rate mortgage loans which have been underwritten to Freddie Mac and Fannie Mae guidelines and have similar risk characteristics.  The loan loss allowance is determined by first calculating the historical loss rate for this segment of the portfolio.  The loss rate may be adjusted for qualitative and environmental factors.  The allowance for loan loss is calculated by multiplying the adjusted loss rate by the total loans in this segment of the portfolio.
	The adjustments to historical loss experience are based on an evaluation of several qualitative and environmental factors, including:
	·                 changes in lending policies and procedures, including changes in underwriting standards and collections, charge-off and recovery practices;
	·                 changes in international, national, and local economic trends;
	·                 changes in the types of loans in the loan portfolio;
	·                 changes in the experience and ability of personnel in the mortgage loan origination and loan servicing departments;
	·                 changes in the number and amount of delinquent loans and classified assets;
	·                 changes in the type and volume of loans being originated;
	·                 changes in the value of underlying collateral for collateral dependent loans;
	·                 changes in any concentration of credit; and
	·                 external factors such as competition, legal and regulatory requirements on the level of estimated credit losses in the existing loan portfolio.
	The Company also uses historical loss rates adjusted for qualitative and environmental factors to establish loan loss allowances for the following portfolio segments:
	·                 home equity loans and lines of credit; and
	·                 consumer and other loans.
	The Company has a limited loss experience for the construction, commercial and other mortgage segment of the loan portfolio.  The loan loss allowance on this portfolio segment is determined using the loan loss rate of other financial institutions in the State of Hawaii.  The allowance for loan loss is calculated by multiplying the loan loss rate of other financial institutions in the state by the total loans in this segment of the Company’s loan portfolio.
	In addition, the unallocated allowance is established to provide for probable losses that have been incurred as of the reporting date but are not reflected in the allocated allowance.
	While the Company uses the best information available to make evaluations, future adjustments to the allowance may be necessary if conditions differ substantially from the information used in making the evaluations.  In addition, as an integral part of their examination process, the Office of the Comptroller of the Currency will periodically review the allowance for loan losses.  The Office of the Comptroller of the Currency may require the Company to increase the allowance based on their analysis of information available at the time of their examination.
	(j)                         Transfer of Financial Assets
	Transfers of financial assets are accounted for as sales when control is surrendered. Control is surrendered when the assets have been isolated from the Company, the transferee obtains the right to pledge or exchange the assets without constraint, and the Company does not maintain effective control over the transferred assets. Mortgage loans sold for cash are accounted for as sales as the above criteria have been met.
	Mortgage loans may also be packaged into securities that are issued and guaranteed by U.S. government-sponsored enterprises. The Company receives 100% of the mortgage-backed securities issued. Securitizations are not accounted for as sales and no gain or loss is recognized. The mortgage-backed securities received in securitizations are valued at amortized cost and classified as held-to-maturity.
	Mortgage loan transfers accounted for as sales and securitizations are without recourse, except for normal representations and warranties provided in sales transactions, and the Company may retain the related rights to service the loans.  The retained servicing rights create mortgage servicing assets that are accounted for in accordance with the Transfers and Servicing topic of the FASB ASC.  Mortgage servicing assets are initially valued at fair value and subsequently at the lower of cost or fair value and are amortized in proportion to and over the period of estimated net servicing income.  The Company uses a discounted cash flow model to determine the fair value of retained mortgage servicing rights. Prior to 2010, we retained the servicing rights on residential mortgage loans sold.  In 2010, we began selling loans primarily on a servicing-released basis.
	(k)                      Premises and Equipment
	Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is principally computed on the straight-line method over the estimated useful lives of the respective assets. The estimated useful life of buildings and improvements is 30 years, furniture, fixtures, and equipment is 3 to 10 years, and automobiles are 3 years. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or estimated useful life of the asset.
	(l)                         Income Taxes
	The Company files consolidated federal income tax and consolidated state franchise tax returns.
	Deferred tax assets and liabilities are recognized using the asset and liability method of accounting for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	We establish income tax contingency reserves for potential tax liabilities related to uncertain tax positions.  A liability for income tax uncertainties would be recorded for unrecognized tax benefits related to uncertain tax positions where it is more likely than not that the position will be sustained upon examination by a taxing authority.
	As of December 31, 2013 and 2012, the Company had not recognized a liability for income tax uncertainties in the accompanying consolidated balance sheets. Management concluded that a liability for income tax uncertainties is not expected to be recorded within the next 12 months.
	Tax years 2010 to 2012 currently remain subject to examination by the Internal Revenue Service and by the Department of Taxation of the State of Hawaii.
	(m)                   Impairment of Long-Lived Assets
	Long-lived assets, such as premises and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the consolidated balance sheets and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated.
	(n)                      Pension Plan
	Pension benefit costs (returns) are charged (credited) to salaries and employee benefits expense, and the corresponding prepaid (accrued) pension cost is recorded in prepaid expenses and other assets or accounts payable and accrued expenses in the consolidated balance sheets. The Company’s policy is to fund pension costs in amounts that will not be less than the minimum funding requirements of the Employee Retirement Income Security Act of 1974 and will not exceed the maximum tax-deductible amounts. The Company generally funds at least the net periodic pension cost, subject to limits and targeted funded status as determined with the consulting actuary.
	(o)                      Employee Stock Ownership Plan (ESOP)
	The cost of shares issued to the ESOP, but not yet allocated to participants, is shown as a reduction of stockholders’ equity.  Compensation expense is based on the market price of shares as they are committed to be released to participant accounts.  Dividends on allocated ESOP shares reduce retained earnings; dividends on unearned ESOP shares reduce debt and accrued interest.
	(p)                      Earnings Per Share
	Basic earning per share is computed by dividing net income by the weighted-average number of common shares outstanding during the period.  Diluted earnings per share is computed by dividing net income by the sum of the weighted-average number of shares outstanding plus the dilutive effect of stock options and restricted stock.  ESOP shares not committed to be released are not considered outstanding.
	(q)                      Common Stock Repurchase Program
	In 2013, 2011 and 2010, the Company adopted common stock repurchase programs in which shares repurchased reduce the amount of shares issued and outstanding.  The repurchased shares may be reissued in connection with share-based compensation plans and for general corporate purposes.  As of December 31, 2013 and 2012, the Company had accumulated repurchases of 2,528,259 and 1,684,171 shares, respectively, of the total 2,699,253 and 1,867,253 shares authorized by the Board of Directors, respectively.  During 2013 and 2012, shares were repurchased at an average cost of $22.58 and $21.52, respectively.
	(r)                        Bank-Owned Life Insurance
The Company’s investment in bank-owned life insurance is based on cash surrender value.  The Company invests in bank-owned life insurance to provide a funding source for benefit plan obligations. Bank-owned life insurance also generally provides noninterest income that is nontaxable. Federal regulations generally limit the investment in bank-owned life insurance to 25% of the Company’s Tier 1 capital plus the allowance for loan losses.  At December 31, 2013, this limit was $50.4 million, and the Company had invested $40.2 million in bank-owned life insurance at that date.
(s)                        Use of Estimates
The preparation of the consolidated financial statements requires management to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include the allowance for loan losses; valuation of certain investment securities and determination as to whether declines in fair value below amortized cost are other than temporary; valuation allowances for deferred income tax assets; mortgage servicing assets; and assets and obligations related to employee benefit plans.  Accordingly, actual results could differ from those estimates.
(t)                         Recently Issued Accounting Pronouncements
In June 2011, the Financial Accounting Standards Board (FASB) amended the Comprehensive Income topic of the FASB Accounting Standards Codification (ASC).  The amendment eliminated the option of presenting components of other comprehensive income as part of the statement of changes in stockholders’ equity.  Nonowner changes in stockholders’ equity must be presented either in a continuous statement of comprehensive income or in two separate but consecutive statements.  The amendment was effective for interim or annual periods beginning after December 15, 2011, with early adoption permitted.  In December 2011, the FASB deferred the effective date of the part of this amendment requiring reclassifications out of accumulated other comprehensive income to be shown on the face of the financial statements to allow time for further deliberation.  Until final reporting requirements were effective, previous disclosure requirements would remain in effect.  The Company adopted this amendment on January 1, 2012, and other than the location of disclosures related to other comprehensive income, the adoption did not have a material effect on its consolidated financial statements.  In February 2013, the FASB finalized the reporting requirements for reclassifications out of accumulated other comprehensive income.  When an amount reclassified out of accumulated other comprehensive income is required to be reported in net income in its entirety, the effect on income statement items must be disclosed.  When an amount reclassified out of accumulated other comprehensive income is not required to be reported in net income in its entirety in the same period, cross references to other required disclosures providing information about the transaction are required.  This amendment was effective for reporting periods beginning after December 15, 2012.  The Company adopted this amendment on January 1, 2013 and the adoption did not have a material effect on its consolidated financial statements.
In December 2011, the FASB amended the Balance Sheet topic of the FASB ASC.  The amendment requires disclosures about the gross and net information related to instruments and transactions eligible for offset in the statement of financial position.  The disclosures are meant to assist users of financial statements to more easily compare information that is presented based on the differing offsetting requirements of U.S. generally accepted accounting principles and International Financial Reporting Standards. In January 2013, the FASB issued a clarification that stated the amendment applies only to certain derivatives, repurchase and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset or subject to an enforceable master netting arrangement or similar agreement.  The amendment was effective for interim and annual periods beginning on or after January 1, 2013.  The Company adopted this amendment on January 1, 2013 and the adoption did not have a material effect on its consolidated financial statements.
In January 2014, the FASB amended the Receivables topic of the FASB ASC.  The amendment clarifies when an in substance repossession or foreclosure occurs and when a mortgage loan should be derecognized and the related real property recognized.  The amendment also requires disclosures about the amount of foreclosed residential real property held and the recorded investment in mortgage loans collateralized by residential real property in the process of foreclosure.  The amendment is effective for interim and annual periods beginning after December 15, 2014, with early adoption allowed.  The Company does not expect the adoption of this amendment to have a material effect on its consolidated financial statements.

	In 2013, the Company received proceeds of $51.1 million from the sale of $47.7 million of held-to-maturity debt securities, resulting in gross realized gains of $3.5 million.  In 2012, the Company received proceeds of $17.2 million from the sale of $16.0 million of held-to-maturity debt securities, resulting in gross realized gains of $1.2 million.  In 2011, the Company received proceeds of $3.8 million from the sale of $3.5 million of held-to-maturity debt securities, resulting in gross realized gains of $261,000.  The sale of these securities, for which the Company had already collected a substantial portion of the outstanding principal (at least 85%), is in accordance with the Investment topic of the FASB ASC and will not affect the historical cost basis used to account for the remaining securities in the held-to-maturity portfolio.
	Investment securities with carrying values of $273.2 million and $221.3 million at December 31, 2013 and 2012, respectively, were pledged to secure public deposits, securities sold under agreements to repurchase and transaction clearing accounts.
	Provided below is a summary of investment securities, which were in an unrealized loss position at December 31, 2013 and 2012. The Company does not intend to sell these securities until such time as the value recovers or the securities mature and it is not more likely than not that the Company will be required to sell the securities prior to recovery of value or the securities mature.

	Mortgage-backed securities	$	32,921	$	253		$	47		$	1	21	$	32,968	$	254
	Mortgage-Backed Securities. The unrealized losses on the Company’s investment in mortgage-backed securities were caused by increases in market interest rates. All of the mortgage-backed securities are guaranteed by Freddie Mac or Fannie Mae, which are U.S. government-sponsored enterprises, or Ginnie Mae, which is a U.S. government agency. Since the decline in market value is attributable to changes in interest rates and not credit quality, and the Company does not intend to sell these investments until maturity and it is not more likely than not that the Company will be required to sell such investments prior to recovery of its amortized cost basis, the Company does not consider these investments to be other-than-temporarily impaired as of December 31, 2013 and 2012.
	Trust Preferred Securities. At December 31, 2013, the Company owns two trust preferred securities, PreTSL XXIII and XXIV. The trust preferred securities represent investments in a pool of debt obligations issued primarily by holding companies for Federal Deposit Insurance Corporation-insured financial institutions.  Both of these securities are classified in the Company’s held-to-maturity investment portfolio.
	The trust preferred securities market is considered to be inactive as only three transactions have occurred over the past 24 months in the same tranche of securities owned by the Company.  The Company used a discounted cash flow model to determine whether these securities are other-than-temporarily impaired.  The assumptions used in preparing the discounted cash flow model include the following: estimated discount rates, estimated deferral and default rates on collateral, and estimated cash flows.
	Based on the Company’s review, the Company’s investment in trust preferred securities did not incur additional impairment during the years ended December 31, 2013, 2012 and 2011.
	PreTSL XXIV had a book value of $0 at December 31, 2013.  PreTSL XXIII had a book value of $537,000 at December 31, 2013.  The difference between the book value of $537,000 and the remaining amortized cost basis of $1.1 million is reported as other comprehensive loss and is related to noncredit factors such as the trust preferred securities market being inactive.
	It is reasonably possible that the fair values of the trust preferred securities could decline in the near term if the overall economy and the financial condition of some of the issuers continue to deteriorate and the liquidity of these securities remains low.  As a result, there is a risk that the Company’s remaining amortized cost basis of $1.1 million on its trust preferred securities could be credit-related other-than-temporarily impaired in the near term.  The impairment could be material to the Company’s consolidated statements of income.

	The Company evaluated its investment in FHLB stock for other-than-temporary impairment as of December 31, 2013, consistent with its accounting policies.  Based on the Company’s evaluation of the underlying investment, including the long-term nature of the investment, the liquidity position of the FHLB of Seattle, the actions being taken by the FHLB of Seattle to address its regulatory capital situation and the Company’s intent not to sell the investment for a sufficient period of time to recover the par value, the Company did not consider its FHLB stock other-than-temporarily impaired.  As of December 31, 2013, the FHLB of Seattle had met all of its regulatory capital requirements.  Moody’s Investor Service and Standard and Poor’s Rating Services have given the FHLB of Seattle credit ratings of Aaa and AA, respectively.  Even though the Company did not recognize an other-than-temporary impairment loss on its investment in FHLB stock in 2013, continued deterioration in the FHLB of Seattle’s financial position may result in future impairment losses.

	In 2012, the Company enhanced its methodology for reviewing its loan portfolio when calculating the allowance for loan losses. The modification consisted of additional segmentation of the residential mortgage loan portfolio by items such as year of origination, loan-to-value ratios, owner or nonowner occupancy status and the purpose of the loan (purchase, cash-out refinance, no cash-out refinance or construction).  The allowance for loan loss for each segment of the loan portfolio is determined by calculating the historical loss of each segment for a two- to three-year look-back period and adding a qualitative adjustment for the following factors:
	·                  Changes in lending policies and procedures;
	·                  Changes in economic trends;
	·                  Changes in types of loans in the loan portfolio;
	·                  Changes in experience and ability of personnel in the loan origination and loan servicing departments;
	·                  Changes in the number and amount of delinquent loans and classified assets;
	·                  Changes in our internal loan review system;
	·                  Changes in the value of underlying collateral for collateral dependent loans;
	·                  Changes in any concentrations of credit; and
	·                  External factors such as competition, legal and regulatory requirements on the level of estimated credit losses in the existing loan portfolio.
	The Company also revised the qualitative factors that are used to determine the allowance for loan losses on construction, commercial and other mortgage loans, home equity loans and lines of credit and consumer and other loans.  As a result of these modifications, the Company increased the portion of the allowance for loan losses attributable to construction, commercial and other mortgage loans and decreased the portion of the allowance for loan losses attributable to residential mortgages.  The allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.  The unallocated allowance is established for probable losses that have been incurred as of the reporting date but are not reflected in the allocated allowance.
Management considers the allowance for loan losses at December 31, 2013 to be at an appropriate level to provide for probable losses that can be reasonably estimated based on general and specific conditions at that date.  While the Company uses the best information it has available to make evaluations, future adjustments to the allowance may be necessary if conditions differ substantially from the information used in making the evaluations.  To the extent actual outcomes differ from the estimates, additional provisions for credit losses may be required that would reduce future earnings.  In addition, as an integral part of their examination process, the Office of the Comptroller of the Currency will periodically review the allowance for loan losses.  The Office of the Comptroller of the Currency may require the Company to increase the allowance based on their analysis of information available at the time of their examination.

The Company primarily uses the aging of loans and accrual status to monitor the credit quality of its loan portfolio.  When a mortgage loan becomes seriously delinquent (90 days or more contractually past due), it displays weaknesses that may result in a loss. As a loan becomes more delinquent, the likelihood of the borrower repaying the loan decreases and the loan becomes more collateral-dependent.   A mortgage loan becomes collateral-dependent when the proceeds for repayment can be expected to come only from the sale or operation of the collateral and not from borrower repayments.  Generally, appraisals are obtained after a loan becomes collateral-dependent or is five months delinquent.  The carrying value of collateral-dependent loans is adjusted to the fair value of the collateral less selling costs.  Any commercial real estate, commercial, construction or equity loan that has a loan balance in excess of a specified amount is also periodically reviewed to determine whether the loan exhibits any weaknesses and is performing in accordance with its contractual terms.
The Company had 19 nonaccrual loans with a book value of $6.0 million at December 31, 2013 and 19 nonaccrual loans with a book value of $4.4 million as of December 31, 2012.  The Company collected interest on nonaccrual loans of $164,000 during 2013, but due to regulatory requirements, the Company recorded it as a reduction of principal.  The Company collected or recognized interest income on nonaccrual loans of $105,000 and $32,000 during 2012 and 2011, respectively.  The Company would have recognized additional interest income of $222,000, $115,000 and $95,000 during 2013, 2012, and 2011, respectively, had the loans been accruing interest.  The Company did not have any loans more than 90 days past due and still accruing interest as of December 31, 2013 or 2012.

There were no new troubled debt restructurings within the past 12 months that subsequently defaulted.
The Company had 20 troubled debt restructurings totaling $5.8 million as of December 31, 2013 that were considered to be impaired. This total included 19 one- to four-family residential mortgage loans totaling $5.6 million and one home equity loan for $160,000.  Eight of the loans, totaling $2.5 million, were performing in accordance with their restructured terms and accruing interest at December 31, 2013.  Twelve of the loans, totaling $3.3 million, were performing in accordance with their restructured terms but not accruing interest at December 31, 2013.  The Company had 20 troubled debt restructurings totaling $5.2 million as of December 31, 2012 that were considered to be impaired. This total included 19 one- to four-family residential mortgage loans totaling $5.1 million and one home equity loan for $160,000.  Eight of the loans, totaling $2.5 million, were performing in accordance with their restructured terms and accruing interest at December 31, 2012.  Eleven of the loans, totaling $2.4 million, were performing in accordance with their restructured terms but not accruing interest at December 31, 2012.  One of the loans, for $329,000, was more than 150 days delinquent and not accruing interest as of December 31, 2012.  Restructurings include deferrals of interest and/or principal payments and temporary or permanent reductions in interest rates due to the financial difficulties of the borrowers.  We have no commitments to lend any additional funds to these borrowers.
Nearly all of our real estate loans are collateralized by real estate located in the State of Hawaii. Loan-to-value ratios on these real estate loans generally do not exceed 80% at the time of origination.
During the years ended December 31, 2013 and 2012, the Company sold $82.2 million and $107.9 million, respectively, of mortgage loans held for sale and recognized gains of $1.5 million and $2.4 million, respectively.  The Company had six loans held for sale totaling $2.2 million at December 31, 2013 and 2012.
The Company serviced loans for others of $68.4 million, $84.8 million, and $115.3 million at December 31, 2013, 2012, and 2011, respectively.  Of these amounts, $3.1 million, $5.1 million, and $6.2 million relate to securitizations for which the Company continues to hold the related mortgage-backed securities at December 31, 2013, 2012, and 2011, respectively.  The amount of contractually specified servicing fees earned was $213,000, $275,000, and $348,000 for 2013, 2012, and 2011, respectively.  The fees are reported in service fees on loan and deposit accounts in the consolidated statements of income.
In the normal course of business, the Company has made loans to certain directors and executive officers under terms which management believes are consistent with the Company’s general lending policies.  Loans to directors and executive officers amounted to $1.6 million at December 31, 2013 and $1.7 million at December 31, 2012.

	Mortgage servicing assets are created when the Company sells mortgage loans and retains the rights to service the loans.  Mortgage servicing assets are accounted for in accordance with the Transfers and Servicing topic of the FASB ASC and are initially valued at fair value and subsequently at the lower of cost or fair value.  We amortize mortgage servicing assets in proportion to and over the period of estimated net servicing income.  All servicing assets are grouped into categories based on the interest rate and original term of the loan sold.  Mortgage servicing assets related to loan sales are recorded as a gain on sale of loans and totaled $36,000 and $28,000 for the years ended December 31, 2013 and 2012, respectively.
	The table below presents the changes in our mortgage servicing assets:

	Accumulated amortization	(773		)	(671		)

	2015	67
	2016	59
	2017	51
	2018	43
	Thereafter	279
	Total	$	580
	The Company uses a discounted cash flow model to determine the fair value of retained mortgage servicing assets.  The discounted cash flow model is also used to assess impairment of servicing assets.  Impairments are recorded as adjustments to amortization expense and included in service fees on loan and deposit accounts in the statements of income.  Critical assumptions used in the discounted cash flow model include mortgage prepayment speeds, discount rates, cost of servicing and ancillary income.
	Prepayment speed may be affected by economic factors such as home price appreciation, market interest rates, the availability of other loan products to our borrowers and customer payment patterns.  Prepayment speeds include the impact of all borrower prepayments, including full payoffs, additional principal payments and the impact of loans paid off due to foreclosure liquidations.  As market interest rates decline, prepayment speeds will generally increase as customers refinance existing mortgage loans under more favorable interest rate terms and anticipated cash flows will generally decline resulting in a potential reduction, or impairment, to the fair value of the mortgage servicing assets.  Alternatively, an increase in market interest rates may cause a decrease in prepayment speeds and therefore an increase in the fair value of mortgage servicing assets.
	The table below presents the fair values and key assumptions used in determining the fair values of our mortgage servicing assets as of December 31, 2013 and 2012:
		2013			2012
	Fair value, beginning of year (in thousands)	$	651		$	977

	Weighted average prepayment speed assumption (PSA prepayment speed)	146.0 PSA			207.4 PSA
	Annual cost to service (per loan)	$	55		$	40
	The PSA prepayment model assumes increasing prepayment rates for the first 30 months of a loan’s term and constant prepayment rates thereafter.

	In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not the Company will realize the benefits of these deductible differences. The amount of the deferred tax assets considered realizable, however, could be reduced in the near term if estimates of future taxable income are reduced. There was no valuation allowance for deferred tax assets as of December 31, 2013 and 2012.

	(16)   Employee Benefit Plans
	The Company has a noncontributory defined benefit pension plan (Pension Plan) that covers substantially all employees with at least one year of service. The benefits are based on years of service and the employees’ compensation during the service period. The Company’s policy is to accrue the actuarially determined pension costs and to fund pension costs within regulatory guidelines. The Company reviews its assumptions on an annual basis and makes modifications to the assumptions based on current rates and trends when it is appropriate to do so. The effect of modifications to those assumptions is recorded in accumulated other comprehensive income (AOCI) beginning in 2006 and amortized to net periodic benefit cost over future periods using the corridor method. The Company believes that the assumptions utilized in recording its obligations under the plan are reasonable based on its experience and market conditions.
	On November 4, 2008, the Board of Directors approved changes to the Company’s defined benefit pension plan. Effective December 31, 2008, there will be no further accrual of benefits for any participants, and benefits will not increase with any additional years of service. Employees already enrolled in the Pension Plan as of December 31, 2008 will be 100% vested if they have at least five years of service. For employees with less than five years of service, vesting would occur at the employee’s five-year anniversary date.
	In addition, the Company sponsors a Supplemental Employee Retirement Plan (SERP), a noncontributory supplemental retirement benefit plan, which covers certain current and former employees of the Company for amounts in addition to those provided under the Pension Plan.
	The following table sets forth the status of the Pension Plan and SERP at the dates indicated:

		Pension Plan				SERP
		Year ended December 31,
		2013		2012		2013		2012
	Assumptions used to determine the year-end benefit obligations:
	Discount rate	4.9	%	4.2	%	5.02	%	5.02	%
	Rate of compensation increase	N/A		N/A		5	%	5	%
	The Company does not expect any plan assets to be returned to the Company during calendar year 2014.
	The dates used to determine retirement measurements for the Pension Plan were December 31, 2013 and 2012.
	The Company’s investment strategy for the defined benefit retirement plan is to maintain a consistent rate of return with primary emphasis on capital appreciation and secondary emphasis on income to enhance the purchasing power of the plan’s assets over the long-term and to preserve capital. The investment policy establishes a target allocation for each asset class that is reviewed periodically and rebalanced when considered appropriate. Normal target allocations at December 31, 2013 were 50% domestic equity securities, 15% international equity securities and 35% bonds.  Equity securities primarily include investment in exchange traded funds and large-cap, mid-cap and small-cap mutual funds.  Bonds include U.S. Treasuries, mortgage-backed securities and corporate bonds of companies in diversified industries. Other types of investments include money market funds and savings accounts opened with the Company.
	As of December 31, 2013 and 2012, the Pension Plan’s assets measured at fair value were classified as follows:

Net periodic benefit cost	$	12		$	14		$	(2	)	$	204		$	256	$	613
The estimated prior service cost and net actuarial loss that will be amortized from AOCI into net periodic pension benefit cost in 2014 are $0 and $122,000, respectively.
The expected return on plan assets is based on the weighted-average long-term rates of return for the types of assets held in the plan. The expected return on plan assets is adjusted when there is a change in the expected long-term rate of return or in the composition of assets held in the plan.  The discount rate is based on the return of high-quality fixed-income investments that can be used to fund the benefit payments under the Company’s defined benefit plan.
Based on actuarial calculations, the Company is not expected to make a contribution to the defined benefit pension plan in 2014. The Company expects to make a $17,000 contribution to the SERP in 2014 to cover actual benefit payments.
The Company also has a 401(k) defined contribution plan and profit sharing plan covering all employees after one year of service. The 401(k) plan provides for employer matching contributions, as determined by the Company, based on a percentage of employees’ contributions subject to a maximum amount defined in the plan agreement. The Company’s 401(k) matching contributions, based on 5% of employees’ contributions for 2013, 2012 and 2011, amounted to $51,000, $50,000, and $49,000, respectively. The Company contributes to the profit sharing plan an amount determined by the Board of Directors. No contributions were made to the profit sharing plan for years ended December 31, 2013, 2012, and 2011.

Employee Stock Ownership Plan	'
	(17) Employee Stock Ownership Plan
	Effective January 1, 2009, Territorial Savings Bank adopted an Employee Stock Ownership Plan (ESOP) for eligible employees.  The ESOP borrowed $9.8 million from the Company and used those funds to acquire 978,650 shares, or 8%, of the total number of shares issued by the Company in its initial public offering.  The shares were acquired at a price of $10.00 per share.
	The loan is secured by the shares purchased with the loan proceeds and will be repaid by the ESOP over the 20-year term of the loan with funds from Territorial Savings Bank’s contributions to the ESOP and dividends payable on the shares.  The interest on the ESOP loan is an adjustable rate equal to the prime rate, as published in The Wall Street Journal.  The interest rate adjusts annually and will be the prime rate on the first business day of the calendar year.
	Shares purchased by the ESOP are held by a trustee in an unallocated suspense account, and shares are released annually from the suspense account on a pro-rata basis as principal and interest payments are made by the ESOP to the Company.  The trustee allocates the shares released among participants on the basis of each participant’s proportional share of compensation relative to all participants.  As shares are committed to be released from the suspense account, Territorial Savings Bank reports compensation expense based on the average fair value of shares released with a corresponding credit to stockholders’ equity.  The shares committed to be released are considered outstanding for earnings per share computations.  Compensation expense recognized for each of the years ended December 31, 2013 and 2012 amounted to $1.0 million.
	Shares held by the ESOP trust were as follows:
		December 31,
		2013		2012
	Allocated shares	239,241		191,577
	Unearned shares	733,989		782,921
	Total ESOP shares	973,230		974,498
	Fair value of unearned shares, in thousands	$	17,029	$	17,890
	The ESOP restoration plan is a non-qualified plan that provides supplemental benefits to certain executives who are prevented from receiving the full benefits contemplated by the employee stock ownership plan’s benefit formula.  The supplemental cash payments consist of payments representing shares that cannot be allocated to the participants under the ESOP due to IRS limitations imposed on tax-qualified plans. We accrue for these benefits over the period during which employees provide services to earn these benefits.  For the years ended December 31, 2013 and 2012, we accrued $296,000 and $278,000, respectively, for the ESOP restoration plan.

	(18) Share-Based Compensation
	On August 19, 2010, Territorial Bancorp Inc. adopted the 2010 Equity Incentive Plan, which provides for awards of stock options and restricted stock to key officers and outside directors.  In accordance with the Compensation — Stock Compensation topic of the FASB ASC, the cost of the 2010 Equity Incentive Plan is based on the fair value of the awards on the grant date.  The fair value of restricted stock is based on the closing price of the Company’s stock on the grant date.  The fair value of stock options is estimated using a Black-Scholes option pricing model using assumptions for dividend yield, stock price volatility, risk-free interest rate and option term.  These assumptions are based on our judgments regarding future events, are subjective in nature, and cannot be determined with precision.  The cost of the awards will be recognized on a straight-line basis over the five- to six-year vesting period during which participants are required to provide services in exchange for the awards.
	The Company recognized compensation expense, measured as the fair value of the share-based award on the date of grant, on a straight-line basis over the vesting period.  Share-based compensation is recorded in the statement of income as a component of salaries and employee benefits with a corresponding increase in shareholders’ equity.  The table below presents information on compensation expense and the related tax benefit for all share-based awards:
	(In thousands)	2013			2012			2011

	The fair value of the Company’s stock options was determined using the Black-Scholes option pricing formula.  The following assumptions were used in the formula for 2012 and 2010:
		2012			2010
	Expected volatility	35.82		%	31.98		%

	Expected life (in years)	6.5			6.75
	Grant price for the stock options	$	23.62		$	17.36
	Expected volatility - Based on the historical volatility of the Company’s stock and a peer group of comparable thrifts.
	Risk-free interest rate - Based on the U.S. Treasury yield curve and expected life of the options at the time of grant.
	Expected dividends - Based on the quarterly dividend and the price of the Company’s stock at the time of grant.
	Expected life - Based on a weighted-average of the five- to six-year vesting period and the 10-year contractual term of the stock option plan.
	Grant price for the stock options - Based on the closing price of the Company’s stock at the time of grant.
	Restricted Stock Awards
	Restricted stock awards are accounted for as fixed grants using the fair value of the Company’s stock at the time of grant.  Unvested restricted stock awards may not be disposed of or transferred during the vesting period.  Restricted stock awards carry with them the right to receive dividends.
	The table below presents the restricted stock award activity:

	(21) Commitments
	(a)                      Loan Commitments
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any terms or conditions established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on an individual basis. The Company’s policy is to require suitable collateral, primarily real estate, to be provided by customers prior to disbursement of approved loans. At December 31, 2013 and 2012, the Company had loan commitments aggregating $15.0 million (interest rates from 3.125% to 5.375%) and $39.3 million (interest rates from 2.625% to 5.000%), respectively, primarily consisting of fixed-rate residential first mortgage loans.  In addition to commitments to originate loans, at December 31, 2013 and 2012, the Company had $23.7 million and $22.0 million, respectively, in unused lines of credit to borrowers.
	(b)                      Lease Commitments
	The Company leases a majority of its premises under operating leases expiring on various dates through 2023. Total rental expense comprised minimum rentals of $2.7 million, $2.6 million, and $2.5 million for the years ended December 31, 2013, 2012, and 2011, respectively.
	At December 31, 2013, future minimum rental commitments under all noncancelable operating leases are as follows:
	(Dollars in thousands)
	2014	$	2,556
	2015	2,275
	2016	2,056
	2017	1,812
	2018	1,123
	Thereafter	2,052
	Total	$	11,874
	Certain leases are renegotiable during the period of the lease or have renewal options at the expiration of the lease term. The majority of lease agreements relates to real estate and generally provides that the Company pay taxes, maintenance, insurance, and certain other operating expenses applicable to the leased premises.
	In addition, the Company leases to a tenant certain property that it owns. Future minimum rental income for this noncancelable lease is as follows:
	(Dollars in thousands)
	2014	$	110
	2015	110
	2016	110
	2017	110
	2018	110
	Thereafter	330
	Total	$	880
	Rental income comprised of minimum rentals for 2013, 2012, and 2011 was approximately $110,000, $110,000 and $80,000, respectively.
	(c)                       Reserve Requirements
	The Company is required by the Federal Reserve Bank to maintain reserves based on the amount of deposits held. The reserve requirement at December 31, 2013 and 2012 was $8.4 million and $12.0 million, respectively, and the Company met such requirements.

	Regulatory risk-based capital — computed	$	201,566		$	208,991
	(a)                      Federal Deposit Insurance Corporation Improvement Act (FDICIA)
	FDICIA was signed into law and regulations implementing the Prompt Corrective Action provisions of FDICIA became effective on December 19, 1992. In addition to the Prompt Corrective Action requirements, FDICIA includes significant changes to the legal and regulatory environment for insured depository institutions, including reductions in insurance coverage for certain kinds of deposits; increased supervision by the federal regulatory agencies; increased reporting requirements for insured institutions; and new regulations concerning internal controls, accounting, and operations.
	The Prompt Corrective Action provisions define specific capital categories based on an institution’s capital ratios. However, the regulators may impose higher minimum capital standards on individual institutions or may downgrade an institution from one capital category to a lower category because of safety and soundness concerns. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements.
	The Prompt Corrective Action provisions impose certain restrictions on institutions that are undercapitalized. The restrictions imposed become increasingly more severe as an institution’s capital category declines from “undercapitalized” to “critically undercapitalized.”
	At December 31, 2013 and 2012, the Bank’s core, tangible, Tier 1/risk-based, and total risk-based ratios exceeded the minimum capital thresholds for a “well-capitalized” institution. There are no conditions or events that have changed the institution’s category under the capital guidelines.
	Depending on the amount of dividends to be paid, the Bank is required to either notify or make application to the Office of the Comptroller of the Currency before dividends are paid to the parent company.

Fair Value of Financial Instruments	'
Fair Value of Financial Instruments	'
	(24) Fair Value of Financial Instruments
	In accordance with the Fair Value Measurements and Disclosures topic of the FASB ASC, the Company groups its financial assets and liabilities at fair value into three levels based on the markets in which the financial assets and liabilities are traded and the reliability of the assumptions used to determine fair value as follows:
	·                  Level 1 — Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities traded in active markets. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available.
	·                  Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.
	·                  Level 3 — Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect management’s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of discounted cash flow models and similar techniques that require the use of significant judgment or estimation.
	In accordance with the Fair Value Measurements and Disclosures topic, the Company bases its fair values on the price that it would expect to receive if an asset were sold or the price that it would expect to pay to transfer a liability in an orderly transaction between market participants at the measurement date.  Also as required, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when developing fair value measurements.
	The Company uses fair value measurements to determine fair value disclosures.  Investment securities held for sale and derivatives are recorded at fair value on a recurring basis.  From time to time, the Company may be required to record other financial assets at fair value on a nonrecurring basis, such as loans held for sale, impaired loans and investments, and mortgage servicing assets. These nonrecurring fair value adjustments typically involve application of the lower of cost or fair value accounting or write-downs of individual assets.
	Cash and Cash Equivalents, Accrued Interest Receivable, Accounts Payable and Accrued Expenses, Current Income Taxes Payable, and Advance Payments by Borrowers for Taxes and Insurance. The carrying amount approximates fair value because of the short maturity of these instruments.
	Investment Securities.  The estimated fair values of U.S. government-sponsored mortgage-backed securities are considered Level 2 inputs because the valuation for investment securities utilized pricing models that varied based on asset class and included trade, bid and other observable market information.
	The trust preferred securities represent investments in a pool of debt obligations issued primarily by holding companies for Federal Deposit Insurance Corporation-insured financial institutions.  The trust preferred securities market is considered to be inactive since there have been only three sales transactions of similar rated securities over the past 24 months and no new issues of pooled trust preferred securities have occurred since 2007.  The fair value of our trust preferred securities was determined using a discounted cash flow model.  Our model used a discount rate equal to three-month LIBOR plus 20.00% and provided a fair value estimate of $15.77 per $100 of par value for PreTSL XXIII.
	The discounted cash flow analysis includes a review of all issuers within the pool.  The fair value of the trust preferred securities are classified as Level 3 inputs because they are based on discounted cash flow models.
	FHLB Stock. FHLB stock, which is redeemable for cash at par value, is reported at its par value.
	Loans. The fair value of loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.  The fair value of loans is not based on the concept of exit price.
	Loans Held for Sale. The fair value of loans held for sale is determined based on prices quoted in the secondary market for similar loans.
	Deposits. The fair value of checking and Super NOW savings accounts, passbook accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated by discounting future cash flows using the rates currently offered for deposits with similar remaining maturities.
	Advances From the FHLB and Securities Sold Under Agreements to Repurchase. Fair value is estimated by discounting future cash flows using the rates currently offered to the Company for debt with similar remaining maturities.
	Interest Rate Contracts.  The Company may enter into interest rate lock commitments with borrowers on loans intended to be sold.  To manage interest rate risk on the lock commitments, the Company may also enter into forward loan sale commitments. The interest rate lock commitments and forward loan sale commitments are treated as derivatives and are recorded at their fair value determined by referring to prices quoted in the secondary market for similar contracts.  Interest rate contracts that are classified as assets are included with prepaid expenses and other assets on the consolidated balance sheet while interest rate contracts that are classified as liabilities are included with accounts payable and accrued expenses.
	The estimated fair values of the Company’s financial instruments are as follows:

The fair value of impaired loans that are considered to be collateral-dependent is determined using the value of collateral less estimated selling costs. The fair value of impaired loans not considered to be collateral-dependent is determined using a discounted cash flow analysis.  Assumptions used in the analysis include the discount rate and projected cash flows.  Gains and losses on impaired loans are included in the provision for loan losses in the consolidated statements of income.  Mortgage servicing assets are valued using a discounted cash flow model.  Assumptions used in the model include mortgage prepayment speeds, discount rates, cost of servicing and ancillary income.  Losses on mortgage servicing assets are included in service fees on loan and deposit accounts in the consolidated statements of income.  The fair value of trust preferred securities is determined using a discounted cash flow model.  The assumptions used in the discounted cash flow model are discussed above.  Gains and losses on trust preferred securities that are credit related are included in net other-than-temporary impairment losses in the consolidated statements of income.  Gains and losses on trust preferred securities that are not credit related are included in other comprehensive income in the consolidated statements of comprehensive income.

	(27) Subsequent Events
	On January 30, 2014, the Board of Directors of Territorial Bancorp Inc. declared a quarterly cash dividend of $0.14 per share of common stock.  The dividend was paid on February 27, 2014 to stockholders of record as of February 13, 2014.
	In November 2013, the Bank filed with the Division of Financial Institutions, State of Hawaii, an application to convert from a federal savings bank to a Hawaii-chartered state savings bank.  As part of the charter conversion, the Bank intends to file an application with the Federal Reserve Bank of San Francisco to become a member bank. The Company will continue to be regulated by the Federal Reserve Board and remain a savings and loan holding company.  On February 28, 2014, the Hawaii Commissioner of Financial Institutions approved the Bank’s application. The charter conversion remains subject to regulatory approval of the Federal Reserve Bank of San Francisco, and no timetable has been established for the completion of the charter conversion.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Summary of Significant Accounting Policies	'
Principles of Consolidation	'
	(b)                      Principles of Consolidation
	The consolidated financial statements include the accounts and results of operations of Territorial Bancorp Inc. and its wholly owned subsidiaries, Territorial Savings Bank, Territorial Real Estate Co., Inc., and Territorial Financial Services, Inc. Significant intercompany balances and transactions have been eliminated in consolidation.
Cash and Cash Equivalents	'
	(c)                       Cash and Cash Equivalents
	Cash and cash equivalents includes cash and due from banks, interest-bearing deposits in other banks, federal funds sold, and short-term, highly liquid investments with original maturities of three months or less.
Investment Securities	'
	(d)                      Investment Securities
	The Company classifies and accounts for its investment securities as follows: (1) held-to-maturity debt securities in which the Company has the positive intent and ability to hold to maturity are reported at amortized cost; (2) trading securities that are purchased for the purpose of selling in the near term are reported at fair value, with unrealized gains and losses included in current earnings; and (3) available-for-sale securities not classified as either held-to-maturity or trading securities are reported at fair value, with unrealized gains and losses excluded from current earnings and reported as a separate component of equity. At December 31, 2013 and 2012, the Company classified all of its investments as held-to-maturity.
	A decline in the market value of any available-for-sale or held-to-maturity security below cost, that is deemed to be other than temporary, results in an impairment to reduce the carrying amount to fair value. To determine whether impairment is other than temporary, the Company considers whether it has the intent and ability not to sell and would not be required to sell for a sufficient period of time to recover the remaining amortized cost basis.
	Gains or losses on the sale of investment securities are computed using the specific-identification method. The Company amortizes premiums and accretes discounts associated with investment securities using the interest method over the contractual life of the respective investment security. Such amortization and accretion is included in the interest and dividend income line item in the consolidated statements of income. Dividend and interest income are recognized when earned.
Loans Receivable	'
	(e)                       Loans Receivable
	This policy applies to all loan classes.  Loans receivable are stated at the principal amount outstanding, less the allowance for loan losses, loan origination fees and costs, and commitment fees. Interest on loans receivable is accrued as earned. The Company has a policy of placing loans on a nonaccrual basis when more than 90 days contractually delinquent or when, in the opinion of management, collection of all or part of the principal balance appears doubtful. For nonaccrual loans, the Company records payments received as a reduction in principal. The Company, considering current information and events regarding the borrowers’ ability to repay their obligations, considers a loan to be impaired when it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. When a loan is considered to be impaired, the amount of the impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, if the loan is considered to be collateral dependent, based on the fair value of the collateral less estimated costs to sell.  Impairment losses are written off against the allowance for loan losses. For impaired loans, the Company records payments received as a reduction in principal. A nonaccrual loan may be restored to an accrual basis when principal and interest payments are current and full payment of principal and interest is expected.
Loans Held for Sale	'
	(f)                         Loans Held for Sale
	Loans held for sale are stated at the lower of aggregate cost or market value. Net fees and costs of originating loans held for sale are deferred and are included in the basis for determining the gain or loss on sales of loans held for sale.
Deferred Loan Origination Fees and Unearned Loan Discounts	'
	(g)                      Deferred Loan Origination Fees and Unearned Loan Discounts
	Loan origination and commitment fees and certain direct loan origination costs are being deferred, and the net amount is recognized over the life of the related loan as an adjustment to yield. Net deferred loan fees are amortized using the interest method over the contractual term of the loan, adjusted for actual prepayments. Net unamortized fees on loans paid in full are recognized as a component of interest income.
Real Estate Owned	'
	(h)                      Real Estate Owned
	Real estate owned is valued at the time of foreclosure at fair value, less estimated cost to sell, thereby establishing a new cost basis. The Company obtains appraisals based on recent comparable sales to assist management in estimating the fair value of real estate owned. Subsequent to acquisition, real estate owned is valued at the lower of cost or fair value, less estimated cost to sell. Declines in value are charged to expense through a direct writedown of the asset. Costs related to holding real estate are charged to expense while costs related to development and improvements are capitalized.
	Profits from the sale of real estate are recognized when title has passed, minimum down payment requirements are met, the terms of any notes received are such as to satisfy continuing investment requirements, and the Company is relieved of any requirements for continued involvement with the properties. If the minimum down payment or the continuing investment is not adequate to meet the criteria specified in the Property, Plant and Equipment topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC), the Company will defer income recognition and account for such sales using alternative methods, such as installment, deposit, or cost recovery.
Allowance for Loan Losses	'
	(i)                         Allowance for Loan Losses
	The Company’s allowance for loan losses is maintained at a level considered adequate to provide for losses that can be estimated based upon specific and general conditions. All loan losses are charged, and all recoveries are credited, to the allowance for loan losses. Additions to the allowance for loan losses are provided by charges to income based on various factors, which, in the Company’s judgment, deserve current recognition in estimating probable losses. Charge-offs to the allowance are made when management determines that collectability of all or a portion of a loan is doubtful and available collateral is insufficient to repay the loan.
	General allowances are established for loan losses on a portfolio basis for loans that do not meet the definition of impaired, in accordance with the Receivables topic of the FASB ASC.  The portfolio is grouped into similar risk characteristics, primarily loan type and delinquency status. The Company applies an estimated loss rate to each loan group. The loss rates applied are based upon its loss experience adjusted, as appropriate, for environmental factors discussed below. This evaluation is inherently subjective, as it requires material estimates that may be susceptible to significant revisions based upon changes in economic and real estate market conditions.  Actual loan losses may be significantly more than the allowance for loan losses the Company has established, which could have a material negative effect on its financial results.
	Residential mortgage loans represent the largest segment of the Company’s loan portfolio.  All of the residential mortgage loans are secured by a first mortgage on residential real estate in Hawaii and consist primarily of fixed-rate mortgage loans which have been underwritten to Freddie Mac and Fannie Mae guidelines and have similar risk characteristics.  The loan loss allowance is determined by first calculating the historical loss rate for this segment of the portfolio.  The loss rate may be adjusted for qualitative and environmental factors.  The allowance for loan loss is calculated by multiplying the adjusted loss rate by the total loans in this segment of the portfolio.
	The adjustments to historical loss experience are based on an evaluation of several qualitative and environmental factors, including:
	·                 changes in lending policies and procedures, including changes in underwriting standards and collections, charge-off and recovery practices;
	·                 changes in international, national, and local economic trends;
	·                 changes in the types of loans in the loan portfolio;
	·                 changes in the experience and ability of personnel in the mortgage loan origination and loan servicing departments;
	·                 changes in the number and amount of delinquent loans and classified assets;
	·                 changes in the type and volume of loans being originated;
	·                 changes in the value of underlying collateral for collateral dependent loans;
	·                 changes in any concentration of credit; and
	·                 external factors such as competition, legal and regulatory requirements on the level of estimated credit losses in the existing loan portfolio.
	The Company also uses historical loss rates adjusted for qualitative and environmental factors to establish loan loss allowances for the following portfolio segments:
	·                 home equity loans and lines of credit; and
	·                 consumer and other loans.
	The Company has a limited loss experience for the construction, commercial and other mortgage segment of the loan portfolio.  The loan loss allowance on this portfolio segment is determined using the loan loss rate of other financial institutions in the State of Hawaii.  The allowance for loan loss is calculated by multiplying the loan loss rate of other financial institutions in the state by the total loans in this segment of the Company’s loan portfolio.
	In addition, the unallocated allowance is established to provide for probable losses that have been incurred as of the reporting date but are not reflected in the allocated allowance.
	While the Company uses the best information available to make evaluations, future adjustments to the allowance may be necessary if conditions differ substantially from the information used in making the evaluations.  In addition, as an integral part of their examination process, the Office of the Comptroller of the Currency will periodically review the allowance for loan losses.  The Office of the Comptroller of the Currency may require the Company to increase the allowance based on their analysis of information available at the time of their examination.
Transfer of Financial Assets	'
	(j)                         Transfer of Financial Assets
	Transfers of financial assets are accounted for as sales when control is surrendered. Control is surrendered when the assets have been isolated from the Company, the transferee obtains the right to pledge or exchange the assets without constraint, and the Company does not maintain effective control over the transferred assets. Mortgage loans sold for cash are accounted for as sales as the above criteria have been met.
	Mortgage loans may also be packaged into securities that are issued and guaranteed by U.S. government-sponsored enterprises. The Company receives 100% of the mortgage-backed securities issued. Securitizations are not accounted for as sales and no gain or loss is recognized. The mortgage-backed securities received in securitizations are valued at amortized cost and classified as held-to-maturity.
	Mortgage loan transfers accounted for as sales and securitizations are without recourse, except for normal representations and warranties provided in sales transactions, and the Company may retain the related rights to service the loans.  The retained servicing rights create mortgage servicing assets that are accounted for in accordance with the Transfers and Servicing topic of the FASB ASC.  Mortgage servicing assets are initially valued at fair value and subsequently at the lower of cost or fair value and are amortized in proportion to and over the period of estimated net servicing income.  The Company uses a discounted cash flow model to determine the fair value of retained mortgage servicing rights. Prior to 2010, we retained the servicing rights on residential mortgage loans sold.  In 2010, we began selling loans primarily on a servicing-released basis.
Premises and Equipment	'
	(k)                      Premises and Equipment
	Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is principally computed on the straight-line method over the estimated useful lives of the respective assets. The estimated useful life of buildings and improvements is 30 years, furniture, fixtures, and equipment is 3 to 10 years, and automobiles are 3 years. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or estimated useful life of the asset.
Income Taxes	'
	(l)                         Income Taxes
	The Company files consolidated federal income tax and consolidated state franchise tax returns.
	Deferred tax assets and liabilities are recognized using the asset and liability method of accounting for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	We establish income tax contingency reserves for potential tax liabilities related to uncertain tax positions.  A liability for income tax uncertainties would be recorded for unrecognized tax benefits related to uncertain tax positions where it is more likely than not that the position will be sustained upon examination by a taxing authority.
	As of December 31, 2013 and 2012, the Company had not recognized a liability for income tax uncertainties in the accompanying consolidated balance sheets. Management concluded that a liability for income tax uncertainties is not expected to be recorded within the next 12 months.
	Tax years 2010 to 2012 currently remain subject to examination by the Internal Revenue Service and by the Department of Taxation of the State of Hawaii.
Impairment of Long-Lived Assets	'
	(m)                   Impairment of Long-Lived Assets
	Long-lived assets, such as premises and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the consolidated balance sheets and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated.
Pension Plan	'
	(n)                      Pension Plan
	Pension benefit costs (returns) are charged (credited) to salaries and employee benefits expense, and the corresponding prepaid (accrued) pension cost is recorded in prepaid expenses and other assets or accounts payable and accrued expenses in the consolidated balance sheets. The Company’s policy is to fund pension costs in amounts that will not be less than the minimum funding requirements of the Employee Retirement Income Security Act of 1974 and will not exceed the maximum tax-deductible amounts. The Company generally funds at least the net periodic pension cost, subject to limits and targeted funded status as determined with the consulting actuary.
Employee Stock Ownership Plan (ESOP)	'
	(o)                      Employee Stock Ownership Plan (ESOP)
	The cost of shares issued to the ESOP, but not yet allocated to participants, is shown as a reduction of stockholders’ equity.  Compensation expense is based on the market price of shares as they are committed to be released to participant accounts.  Dividends on allocated ESOP shares reduce retained earnings; dividends on unearned ESOP shares reduce debt and accrued interest.
Earnings Per Share	'
	(p)                      Earnings Per Share
	Basic earning per share is computed by dividing net income by the weighted-average number of common shares outstanding during the period.  Diluted earnings per share is computed by dividing net income by the sum of the weighted-average number of shares outstanding plus the dilutive effect of stock options and restricted stock.  ESOP shares not committed to be released are not considered outstanding.
Common Stock Repurchase Program	'
	(q)                      Common Stock Repurchase Program
	In 2013, 2011 and 2010, the Company adopted common stock repurchase programs in which shares repurchased reduce the amount of shares issued and outstanding.  The repurchased shares may be reissued in connection with share-based compensation plans and for general corporate purposes.  As of December 31, 2013 and 2012, the Company had accumulated repurchases of 2,528,259 and 1,684,171 shares, respectively, of the total 2,699,253 and 1,867,253 shares authorized by the Board of Directors, respectively.  During 2013 and 2012, shares were repurchased at an average cost of $22.58 and $21.52, respectively.
Bank-Owned Life Insurance	'
	(r)                        Bank-Owned Life Insurance
	The Company’s investment in bank-owned life insurance is based on cash surrender value.  The Company invests in bank-owned life insurance to provide a funding source for benefit plan obligations. Bank-owned life insurance also generally provides noninterest income that is nontaxable. Federal regulations generally limit the investment in bank-owned life insurance to 25% of the Company’s Tier 1 capital plus the allowance for loan losses.  At December 31, 2013, this limit was $50.4 million, and the Company had invested $40.2 million in bank-owned life insurance at that date.
Use of Estimates	'
	(s)                        Use of Estimates
	The preparation of the consolidated financial statements requires management to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include the allowance for loan losses; valuation of certain investment securities and determination as to whether declines in fair value below amortized cost are other than temporary; valuation allowances for deferred income tax assets; mortgage servicing assets; and assets and obligations related to employee benefit plans.  Accordingly, actual results could differ from those estimates.
Recently Issued Accounting Pronouncements	'
	(t)                         Recently Issued Accounting Pronouncements
	In June 2011, the Financial Accounting Standards Board (FASB) amended the Comprehensive Income topic of the FASB Accounting Standards Codification (ASC).  The amendment eliminated the option of presenting components of other comprehensive income as part of the statement of changes in stockholders’ equity.  Nonowner changes in stockholders’ equity must be presented either in a continuous statement of comprehensive income or in two separate but consecutive statements.  The amendment was effective for interim or annual periods beginning after December 15, 2011, with early adoption permitted.  In December 2011, the FASB deferred the effective date of the part of this amendment requiring reclassifications out of accumulated other comprehensive income to be shown on the face of the financial statements to allow time for further deliberation.  Until final reporting requirements were effective, previous disclosure requirements would remain in effect.  The Company adopted this amendment on January 1, 2012, and other than the location of disclosures related to other comprehensive income, the adoption did not have a material effect on its consolidated financial statements.  In February 2013, the FASB finalized the reporting requirements for reclassifications out of accumulated other comprehensive income.  When an amount reclassified out of accumulated other comprehensive income is required to be reported in net income in its entirety, the effect on income statement items must be disclosed.  When an amount reclassified out of accumulated other comprehensive income is not required to be reported in net income in its entirety in the same period, cross references to other required disclosures providing information about the transaction are required.  This amendment was effective for reporting periods beginning after December 15, 2012.  The Company adopted this amendment on January 1, 2013 and the adoption did not have a material effect on its consolidated financial statements.
	In December 2011, the FASB amended the Balance Sheet topic of the FASB ASC.  The amendment requires disclosures about the gross and net information related to instruments and transactions eligible for offset in the statement of financial position.  The disclosures are meant to assist users of financial statements to more easily compare information that is presented based on the differing offsetting requirements of U.S. generally accepted accounting principles and International Financial Reporting Standards. In January 2013, the FASB issued a clarification that stated the amendment applies only to certain derivatives, repurchase and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset or subject to an enforceable master netting arrangement or similar agreement.  The amendment was effective for interim and annual periods beginning on or after January 1, 2013.  The Company adopted this amendment on January 1, 2013 and the adoption did not have a material effect on its consolidated financial statements.
	In January 2014, the FASB amended the Receivables topic of the FASB ASC.  The amendment clarifies when an in substance repossession or foreclosure occurs and when a mortgage loan should be derecognized and the related real property recognized.  The amendment also requires disclosures about the amount of foreclosed residential real property held and the recorded investment in mortgage loans collateralized by residential real property in the process of foreclosure.  The amendment is effective for interim and annual periods beginning after December 15, 2014, with early adoption allowed.  The Company does not expect the adoption of this amendment to have a material effect on its consolidated financial statements.
