	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.
	On June 25, 2014, Territorial Savings Bank converted from a federal savings bank to a Hawaii state-chartered savings bank.

	In January 2014, the Financial Accounting Standards Board (FASB) amended the Receivables topic of the FASB Accounting Standards Codification (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 May 2014, the FASB amended the Revenue Recognition topic of the FASB ASC.  The amendment seeks to clarify the principles for recognizing revenue as well as to develop common revenue standards for U.S. generally accepted accounting principles and International Financial Reporting Standards.  The amendment is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period.  Early application is not permitted.  The Company does not expect the adoption of this amendment to have a material effect on its consolidated financial statements.
	In June 2014, the FASB amended the Transfers and Servicing topic of the FASB ASC.  The amendment modifies the accounting for certain types of repurchase transactions as well as adds new disclosure requirements for repurchase transactions.  The amendment is effective for interim and annual periods beginning after December 15, 2014, with early adoption prohibited.  The Company does not expect the adoption of this amendment to have a material effect on its consolidated financial statements.

	During the three months ended June 30, 2014 and 2013, the Company received proceeds of $3.5 million and $15.6 million, respectively, from the sale of $3.2 million and $14.5 million, respectively, of held-to-maturity debt securities, resulting in gross realized gains of $309,000 and $1.0 million, respectively.  During the six months ended June 30, 2014 and 2013, the Company received proceeds of $7.2 million and $29.2 million, respectively, from the sale of $6.6 million and $27.3 million, respectively, of held-to-maturity debt securities, resulting in gross realized gains of $625,000 and $1.9 million, respectively.  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 $268.5 million and $273.2 million at June 30, 2014 and December 31, 2013, 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 June 30, 2014 and December 31, 2013.  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	$	3,644	$	14	$	236,464		$	9,520	49	$	240,108	$	9,534
	December 31, 2013:

	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 June 30, 2014 and December 31, 2013.
	Trust Preferred Securities.  At June 30, 2014, 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 Bank’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 30 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 quarter ending June 30, 2014.
	PreTSL XXIV has a book value of $0 at June 30, 2014.  PreTSL XXIII has a book value of $657,000 at June 30, 2014.  The difference between the book value of $657,000 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.

Management considers the allowance for loan losses at June 30, 2014 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 bank regulatory agencies periodically review the allowance for loan losses and 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 18 nonaccrual loans with a book value of $5.1 million at June 30, 2014 and 19 nonaccrual loans with a book value of $6.0 million as of December 31, 2013.  The Company collected interest on nonaccrual loans of $135,000 and $77,000 during the six months ended June 30, 2014 and 2013, respectively, but due to regulatory requirements, we recorded it as a reduction of principal.  The Company would have recognized additional interest income of $96,000 and $141,000 during the six months ended June 30, 2014 and 2013, 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 June 30, 2014 and December 31, 2013.

There were no new troubled debt restructurings within the past 12 months that subsequently defaulted.
The Company had 18 troubled debt restructurings totaling $5.0 million as of June 30, 2014 that were considered to be impaired.  This total included 17 one- to four-family residential mortgage loans totaling $4.9 million and one home equity loan for $142,000.  Six of the loans, totaling $2.0 million, are performing in accordance with their restructured terms and accruing interest at June 30, 2014.  Eleven of the loans, totaling $2.8 million, are performing in accordance with their restructured terms but not accruing interest at June 30, 2014.  One of the loans, for $191,000, is more than 149 days delinquent and not accruing interest as of June 30, 2014.  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.  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 six months ended June 30, 2014 and 2013, the Company sold $16.9 million and $47.1 million, respectively, of mortgage loans held for sale and recognized gains of $165,000 and $1.0 million, respectively.  During the three months ended June 30, 2014 and 2013, the Company sold $7.0 million and $22.3 million, respectively, of mortgage loans held for sale and recognized gains of $86,000 and $380,000, respectively.  The Company had six loans held for sale totaling $1.5 million at June 30, 2014 and six loans held for sale totaling $2.2 million at December 31, 2013.
The Company serviced loans for others of $65.2 million at June 30, 2014 and $68.4 million at December 31, 2013. Of these amounts, $2.6 million and $3.1 million relate to securitizations for which the Company continues to hold the related mortgage-backed securities at June 30, 2014 and December 31, 2013, respectively.  The amount of contractually specified servicing fees earned for the six-month periods ended June 30, 2014 and 2013 was $93,000 and $113,000, respectively.  The amount of contractually specified servicing fees earned for the three-month periods ended June 30, 2014 and 2013 was $46,000 and $55,000, respectively.  The fees are reported in service fees on loan and deposit accounts in the consolidated statements of income.

	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 rate 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 the three months ended June 30, 2014 and 2013 amounted to $217,000 and $261,000, respectively.  Compensation expense recognized for the six months ended June 30, 2014 and 2013 amounted to $458,000 and $523,000, respectively.
	Shares held by the ESOP trust were as follows:
		June 30,		December 31,
		2014		2013
	Allocated shares	259,693		239,241
	Unearned shares	709,523		733,989
	Total ESOP shares	969,216		973,230
	Fair value of unearned shares, in thousands	$	14,815	$	17,029
	The ESOP restoration plan is a nonqualified 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 three months ended June 30, 2014 and 2013, we accrued $19,000 and $31,000, respectively, for the ESOP restoration plan.  For the six months ended June 30, 2014 and 2013, we accrued $93,000 and $120,000, respectively, for the ESOP restoration plan.

	(11)                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:

Fair Value of Financial Instruments	'
Fair Value of Financial Instruments	'
	(14)                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 as only three transactions have occurred over the past 30 months in the same tranche of securities owned by the Company.  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 $18.54 per $100 of par value for PreTSL XXIII.
	The discounted cash flow analysis included 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 the 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.  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.
