Organization Consolidation And Presentation Of Financial Statements [Abstract]
Nature of Business	Note 1 – Nature of Business Organization The accompanying condensed consolidated financial statements include the accounts of BankGuam Holding Company (“Company”) and its wholly-owned subsidiaries, Bank of Guam (“Bank”) and BankGuam Investment and Insurance Services (“BGIIS”). The Company is a Guam corporation organized on October 29, 2010, to act as the holding company of the Bank, a Guam banking corporation, a 23-branch bank serving the communities in Guam, the Commonwealth of the Northern Mariana Islands (CNMI), the Federated States of Micronesia (FSM), the Republic of the Marshall Islands (RMI), the Republic of Palau (ROP), and San Francisco, California. BankGuam Investment and Insurance Services was incorporated in Guam in 2015 and initially capitalized during the first quarter of 2016. During July 2016, the Company executed an agreement to purchase 25% of ASC Trust Corporation. Other than holding the shares of the Bank, BGIIS and ASC Trust Corporation, the Company conducts no significant activities, although it is authorized, with the prior approval of its principal regulator, the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”), to engage in a variety of activities related to the business of banking. Currently, substantially all of the Company’s operations are conducted and substantially all of the assets are owned by the Bank, which accounts for substantially all of our consolidated revenues, expenses and operating income. The Bank provides a variety of financial services to individuals, businesses and governments through its branches. The Bank’s headquarters is located in Hagåtña, Guam. The Bank currently has twelve branches in Guam, four in the CNMI, four in the FSM, one in the RMI, one in the ROP, and one in San Francisco, California. Its primary deposit products are demand deposits, savings and time certificate accounts, and its primary lending products are consumer, commercial and real estate loans. For ease of reference we will sometimes refer to the Company hereinafter as “we”, “us” or “our.”

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 – Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in effect in the United States (“GAAP”), on a basis consistent with prior periods. Certain prior period amounts have been reclassified to conform to current year presentation. The consolidated financial statements include the accounts of BankGuam Holding Company, the Bank BGIIS, and the Bank’s wholly owned subsidiaries, BankGuam Properties, Inc. and BankGuam Insurance Underwriters, Ltd. All significant intercompany and inter-branch balances and transactions have been eliminated in consolidation. The Company evaluates other entities to determine whether they are variable interest entities (“VIEs”). A VIE is a company in which equity investors do not have the characteristics of a controlling financial interest or where the entity does not have enough equity at risk to finance its activities without additional subordinated financial support from other parties. A variable interest in a VIE can arise from contractual, ownership or other monetary interests in the entity, which change with fluctuations in the fair value of the entity’s net assets. The Company would consolidate a VIE if it is the primary beneficiary. A primary beneficiary is the entity which holds both the power to direct the activities that most significantly impact the VIE and a variable interest that potentially could be significant to the VIE. The Company does not consolidate any VIEs. Assets held by the Bank’s Trust and Wealth Management departments in a fiduciary capacity are not assets of the Bank, and, accordingly, are not included in the accompanying consolidated financial statements. Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the periods presented. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, valuation of other real estate owned and the fair value of financial instruments. Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash on hand and balances due from banks, Federal Funds sold, cash items in transit and interest bearing deposits with other banks. The Bank is required by the Federal Reserve System to maintain cash reserves against certain of its deposit accounts. At December 31, 2016 and 2015, the required combined reserves totaled approximately $35.9 million and $25.6 million, respectively. Restricted Cash Interest-bearing deposits in banks that mature within one year are carried at cost. $150 thousand of these deposits are held jointly under the names of Bank of Guam and the Guam Insurance Commissioner, and serve as a bond for the Bank of Guam Trust Department, and $250 thousand of these deposits are held under the Bank of Guam and are pledged for the Banker’s Loan Processing (BLP) program. Investment Securities Certain debt securities that management has the positive intent and ability to hold to maturity are classified as “held-to-maturity,” and are recorded at amortized cost. Securities not classified as held-to-maturity, including equity securities with readily determinable fair value, are classified as “available-for-sale” and are recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. The Bank does not hold securities for trading purposes. Declines in the fair value of securities below their cost that are other than temporary are reflected in earnings as realized losses. In determining other-than-temporary losses, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment, and is based on the information available to management at the time such a determination is made. Federal Home Loan Bank Stock The Bank is required to hold non-marketable equity securities, comprised of Federal Home Loan Bank of Des Moines (“FHLB”) stock, as a condition of membership. These securities are accounted for at cost, which equals par or redemption value. Ownership is restricted and there is no market for these securities. These securities are redeemable at par by the issuing government supported institutions. The primary factor supporting the carrying value is the commitment of the FHLB to perform its obligations, which includes providing credit and other services to the Bank. Mortgage Servicing Rights (MSR) Mortgage servicing assets, included in other assets in the consolidated statements of financial condition, are recognized separately when rights are acquired through the sale of mortgage loans. Under the servicing assets and liabilities accounting guidance in ASC Topic 860, “ Transfers and Servicing Loans Held for Investment Loans held for investment generally are reported at their outstanding unpaid principal balances, adjusted for charge-offs, an allowance for loan losses, and any deferred fees or costs on originated loans, as well as unamortized premiums or discounts on purchased loans, except for certain purchased loans that fall under the scope of Accounting Standards Codification (ASC) Topic 310-30, “ Accounting for Loans and Debt Securities Acquired with Deteriorated Credit Quality Interest income is accrued on the unpaid principal balance of loans. Loan origination fees, net of certain direct origination costs, are deferred and recognized as income using the effective interest method over the contractual life of the loans. The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Credit card loans and other unsecured consumer loans are typically charged off no later than 180 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on non-accrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on non-accrual or charged off are reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Loan Origination Fees and Costs All loan origination fees and related direct costs are deferred and amortized to interest income as an adjustment to yield over the respective lives of the loans using the effective interest method, except for loans that are revolving or short-term in nature for which the straight line method is used, which approximates the interest method. Allowance for Loan Losses, Impaired Loans and Troubled Debt Restructurings The allowance for loan losses is established as losses are estimated to be likely, and is funded through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectability of a loan is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is first determined by analyzing all classified loans (Substandard and Doubtful) in non-accrual for loss exposure and establishing specific reserves, as needed. ASC 310-10 defines loan impairment as the existence of uncertainty concerning collection of all principal and interest per the contractual terms of a loan. For collateral-dependent loans, impairment is typically measured by comparing the loan amount to the fair value of collateral, less costs to sell, with a specific reserve established for the “shortfall” amount. Other methods can be used in estimating impairment (market price or present value of expected future cash flows discounted at the loan’s original interest rate). The allowance for credit losses is management’s estimate of credit losses inherent in the loan portfolio at the balance sheet date. The Company has established a process to determine the appropriateness of the allowance for credit losses that assesses the losses inherent in the loan portfolio. The Company develops and documents its allowance methodology at the portfolio segment level – commercial loan portfolio and consumer loan portfolio. While portions of the allowance are attributable to the respective commercial and consumer portfolio segments, the entire allowance is available to absorb credit losses inherent in the total loan portfolio. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and real estate loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loans’ obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Bank does not separately identify individual consumer loans for impairment disclosures. In situations where, for economic or legal reasons related to a borrower’s financial difficulties, the Bank will grant a concession for other than an insignificant period of time to the borrower that would not otherwise be considered, the related loan is classified as a troubled debt restructuring (TDR). These modified terms may include rate reductions, principal forgiveness, term extensions, payment forbearance and other actions intended to minimize economic loss and to avoid foreclosure or repossession of the collateral, if applicable. For modifications where principal is forgiven, the entire amount of such principal forgiveness is immediately charged off. Loans classified as TDRs, including loans in trial payment periods (trial modifications), are considered impaired loans. Other than resolutions such as foreclosures, the Bank may remove loans held for investment from TDR classification, but only if they have been refinanced or restructured at market terms and qualify as a new loan. Loans Held for Sale In its normal course of business, the Bank originates mortgage loans held for sale to the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”). The Bank has elected to measure its residential mortgage loans held for sale at the lower of cost or market. Origination fees and costs are recognized in earnings at the time of origination for newly originated loans held for sale, and the loans are sold to Freddie Mac at par. The Bank recognizes gains on the sale of loans sold to Freddie Mac only to the extent of MSRs retained in such sales. During the years ended December 31, 2016, 2015 and 2014, the Bank originated and sold approximately $18.6 million, $19.9 million and $22.8 million, respectively, of the above mentioned loans. Off-Balance Sheet Financial Instruments In the ordinary course of business, the Bank has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit and standby letters of credit. Such financial instruments are recorded as off-balance sheet items when the commitment is made, then recorded as balance sheet items if and when funded (See Note 16). Premises and Equipment Premises and equipment are reported at cost, less accumulated depreciation and amortization. Depreciation and amortization are computed on the straight-line method over the estimated useful lives of the related assets. Depreciation expense has been computed principally using estimated lives of 15 to 40 years for premises and 5 to 10 years for furniture and equipment. Leasehold improvements are depreciated over the estimated lives of the assets or the expected terms of the leases, if shorter. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured. Construction-in-progress consists of accumulated direct and indirect costs associated with the Bank’s construction of premises and the purchase of equipment that has not yet been placed in service and, accordingly, has not yet been subjected to depreciation. Such assets begin depreciation over their estimated useful lives when completed and placed in service. Premises and equipment are periodically evaluated for impairment when events or changes in circumstances indicate the carrying amount may not be recoverable. Impairment exists when the expected undiscounted future cash flows of premises and equipment are less than their carrying amount. In that event, the Bank records a loss for the difference between the carrying amount and the estimated fair value of the asset based on quoted prices. Other Real Estate Owned Properties acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at the fair value of the property, reduced by estimated selling costs. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value, less the estimated cost to sell. Other real estate owned is estimated using the appraised value of the underlying collateral, discounted as necessary due to management’s estimates of changes in economic conditions, less estimated costs to sell. A valuation allowance is increased by provisions charged to earnings. Subsequent write-downs, income and expenses incurred in connection with holding such assets, and gains and losses realized from the sale of such assets, are charged to the valuation allowance. Goodwill Goodwill is recorded in business combinations under the purchase method of accounting when the purchase price is greater than the fair value of net assets, including identifiable intangible assets. The Bank will assess goodwill for impairment at a reporting unit level on an annual basis or more frequently in certain circumstances. The Bank has the option of performing a qualitative assessment of goodwill, or to bypass the qualitative test and proceed directly to a quantitative test. If the Bank performs a qualitative assessment of goodwill to test for impairment and conclude it is more likely than not that a reporting unit’s fair value is greater than its carrying amount, quantitative tests are not required. However, if it is determined it is more likely than not that a reporting unit’s fair value is less than its carrying amount, then the Bank completes a quantitative assessment to determine if there is goodwill impairment. The Bank can apply various quantitative valuation methodologies, including discounted cash flow and earnings multiple approaches, to determine the estimated fair value, which is compared to the carrying value of each reporting unit. If the fair value is less than the carrying amount, an additional test is required to measure the amount of impairment. Based on the Bank’s more recent evaluation, no goodwill impairment was recorded. Income Taxes Income taxes represent taxes recognized under laws of the Government of Guam, which generally conform to U.S. income tax laws. Foreign income taxes result from payments of taxes with effective rates ranging from 2% to 5% of gross income in the FSM, the RMI and the ROP to their respective government jurisdictions. U.S. Federal, California and the Commonwealth of the Northern Mariana Islands income taxes are reflected as foreign taxes for financial reporting purposes. The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid for the period by applying the provisions of the enacted tax law to the taxable income. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term, “more likely than not,” means a likelihood of more than 50 percent; the terms, “examined,” and, “upon examination,” also include resolution of related appeals or litigation processes, if any. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. Uncertain tax positions that meet the more likely than not recognition threshold are measured to determine the amount of benefit to recognize. An uncertain tax position is measured at the largest amount of benefit that management believes has a greater than 50% likelihood of realization upon settlement. The Company recognizes interest and penalties on income taxes as a component of income tax expense. Earnings Per Common Share Basic earnings per share represent income available to common stockholders (after deducting dividends on preferred stock) divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may have been issued by the Company relate solely to outstanding stock options, and are determined using the treasury stock method. Fair Value of Financial Instruments/Fair Value Option Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 19. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect these estimates. In addition, the fair value option provides an option to elect fair value as an alternative measurement for selected financial assets, financial liabilities, unrecognized firm commitments and written loan commitments not previously carried at fair value. The Company and the Bank have elected the fair value option for its mortgage servicing rights. The election was made to better reflect the underlying economics and to mitigate operational complexities in risk management activities. Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when, (i) the assets have been isolated from the Bank – put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (ii) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) the Bank does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets. Contingencies From time to time, the Company may become involved in disputes, litigation and other legal actions. In such event, the Company estimates the range of liability related to pending litigation where the amount and range of loss can be estimated and information available prior to the issuance of financial statements indicates such loss is considered probable. Where a liability is probable and there is a range of estimated loss with no best estimate in the range, the Company records a charge equal to at least the minimum amount in the range. Subsequent Events Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued (See Note 20). The Company recognizes in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing the financial statements. The Company’s financial statements do not recognize subsequent events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after the balance sheet date and before financial statements are available to be issued. The Company has evaluated events subsequent through the date that these consolidated financial statements are being filed with the Securities and Exchange Commission.

Recent Accounting Pronouncements	Note 3 – Recent Accounting Pronouncements In November 2015, the FASB issued ASU 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes”, to simplify the presentation of deferred income taxes. This update to Topic 740 require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial condition and will align the presentation of deferred income taxes and liabilities with International Financial Reporting Standards (IFRS). We adopted this update on January 1, 2016, and it did not have a material effect on our consolidated financial condition or results of operations. Recently Issued but Not Yet Adopted Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326)” We are currently evaluating the impact of ASU 2016-13 on our consolidated financial statements, which is effective beginning January 1, 2020.

Interest-Bearing Deposits and Restricted Cash	Note 4 – Interest-Bearing Deposits and Restricted Cash The Company had $151.3 million and $72.7 million in interest bearing deposits, including restricted cash, at other financial institutions at December 31, 2016 and 2015, respectively. The weighted average percentage yields on these deposits were 0.75% and 0.50% at December 31, 2016 and 2015, respectively. Interest bearing deposits with financial institutions can be withdrawn by the Bank on demand, and are considered cash equivalents for purposes of the consolidated statements of financial condition and cash flows. At December 31, 2016 and 2015, we had $400 thousand of restricted cash, held in time deposits that were scheduled to mature within one year. Of these deposits, $150 thousand are held jointly under the names of Bank of Guam and the Guam Insurance Commissioner, and serve as a bond for the Bank of Guam Trust Department, and $250 thousand are held under the Bank of Guam, and are pledged for Banker’s Loan Processing (BLP) program with Pacific Coast Bankers Bank in California. The weighted average percentage yields on these restricted cash deposits were 0.67% and 0.37% at December 31, 2016 and 2015, respectively.

Specifically, the 140 securities are comprised of the following: 80 Small Business Administration (SBA) Pool securities, 7 mortgage-backed securities issued by Federal National Mortgage Association (FNMA), 5 mortgage-backed security issued by Federal Home Loan Mortgage Corporation (FHLMC), 20 mortgage-backed securities issued by Government National Mortgage Association (GNMA), 7 agency securities issued by Federal Home Loan Bank (FHLB), 1 agency security issued by Federal Farm Credit Banks (FFCB), and 20 U.S. Treasuries. Total gross unrealized losses were primarily attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to changes in the credit quality of the investment securities. The Bank does not intend to sell the investment securities that were in an unrealized loss position and it is not likely that the Bank will be required to sell the investment securities before recovery of their amortized cost bases, which may be at maturity. Investment in Unconsolidated Subsidiary In May 2016, the Company entered into a Stock Purchase Agreement to acquire 25% of ASC Trust Corporation, a Guam trust company. In July 2016, subsequent to the approval of the Federal Reserve Bank of San Francisco in June 2016, the purchase was executed. The Company took on $3.5 million in subordinated debt in connection with the purchase to finance the transaction, which debt has since been retired. The Agreement provides for the acquisition of an additional 20% of the stock of ASC Trust Corporation in April 2019, and another 25% in April 2021, with both future purchases subject to regulatory approval. The Agreement contains customary warranties, representations and indemnification provisions.

Loans	Note 6 – Loans The Bank provides commercial and industrial, commercial mortgage, commercial construction, automobile and other consumer loans in each of the markets it serves. It also offers residential mortgage, home equity and certain U.S. government guaranteed loans in Guam, the Northern Mariana Islands and California. Outstanding loan balances are presented net of unearned income, net deferred loan fees, and unamortized discount and premium totaling $2.5 million at December 31, 2016. The loan portfolio consisted of the following at: December 31, 2016 2015 Amount Percent Amount Percent (Dollars in thousands) Commercial Commercial & industrial $ 248,059 21.1 % $ 233,351 21.8 % Commercial mortgage 552,272 47.0 % 420,049 39.2 % Commercial construction 6,421 0.5 % 62,415 5.8 % Commercial agriculture 747 0.1 % - 0.0 % Total commercial 807,499 68.7 % 715,815 66.9 % Consumer Residential mortgage 143,951 12.2 % 144,007 13.5 % Home equity 480 0.0 % 628 0.1 % Automobile 30,798 2.6 % 26,541 2.5 % Other consumer loans 1 193,279 16.4 % 183,597 17.1 % Total consumer 368,508 31.3 % 354,773 33.1 % Gross loans 1,176,007 100.0 % 1,070,588 100.0 % Deferred fee (income) costs, net (2,527 ) (2,179 ) Allowance for loan losses (15,435 ) (14,159 ) Loans, net $ 1,158,045 $ 1,054,250 1 Comprised of other revolving credit, installment, and overdrafts. At December 31, 2016, total gross loans increased by $105.4 million, to $1.18 billion, up from $1.07 billion at December 31, 2015. The growth in loans was largely attributed to (i) an increase of $132.2 million in the commercial mortgage category, to $552.3 million from $420.0 million, primarily due to various large loans originated in the California region and in Guam, (ii) a $14.7 million increase in the commercial and industrial loan category, to $248.1 million from $233.4 million, based primarily on net additions in San Francisco, Guam and the Marshall Islands, (iii) an increase of $9.7 million in the other consumer loan category, from $183.6 million to $193.3 million, primarily due to consumer loan promotions, (iv) an increase of $4.3 million in automobile loans, from $26.5 million to $30.8 million, primarily due to an expanded automobile loan program, and (iv) the issuance of a commercial agriculture loan in the amount of 747 thousand. These were partially offset by a $56.0 million decrease in commercial construction loans, to $6.4 million from $62.4 million, due primarily to the completion of the construction of a project, when the loan was rolled over into a commercial mortgage. Allowance for Loan Losses The allowance for loan losses is evaluated on a regular basis by management, and is based upon management’s periodic review of the collectability of loans in light of historical experience, the nature of volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. The portion of the allowance that covers unimpaired loans is based on historical charge-off experience and expected loss, given the default probability derived from the Bank’s internal risk rating process. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. Our loss migration analysis tracks a certain number of quarters of loan loss history and industry loss factors to determine historical losses by classification category for each loan type, except certain consumer loans. These calculated loss factors are then applied to outstanding loan balances for all loans on accrual designated as “Pass,” “Special Mention,” “Substandard” or “Doubtful” (“classification categories”). Additionally, a qualitative factor that is determined utilizing external economic factors and internal assessments is applied to each homogeneous loan pool. We also conduct individual loan review analyses, as part of the allowance for loan loss allowance allocation process, applying specific monitoring policies and procedures in analyzing the existing loan portfolios. Credit Quality Indicators The Bank uses several credit quality indicators to manage credit risk, including an internal credit risk rating system that categorizes loans and leases into pass, special mention, substandard, doubtful or loss categories. Credit risk ratings are applied individually to those classes of loans and leases that have significant or unique credit characteristics and that benefit from a case-by-case evaluation. These are typically loans and leases to businesses or individuals in the classes which comprise the commercial portfolio segment. Groups of loans and leases that are underwritten and structured using standardized criteria and characteristics, such as statistical models (e.g., credit scoring or payment performance), are typically risk-rated and monitored collectively. These are typically loans and leases to individuals in the classes which comprise the consumer portfolio segment. The following are the definitions of the Bank’s credit quality indicators: Pass (A): Exceptional: Essentially risk-free credit. These are loans of the highest quality that pose virtually no risk of loss to the Bank. This includes loans fully collateralized by means of a savings account(s) and time certificate(s) of deposit, and by at least 110% of the loan amount. Borrowers should have strong financial statements, good liquidity and excellent credit. Pass (B): Standard: Multiple “strong sources of repayment.” Loans to strong borrowers with a demonstrated history of financial and managerial performance. Risk of loss is considered to be low. Loans are well structured, with clearly identified primary and readily available secondary sources of repayment. Loans maybe secured by an equal amount of funds in a savings account or time certificate of deposit. Loans may be secured by marketable collateral whose value can be reasonably determined through outside appraisals. Very strong cash flow and relatively low leverage. Pass (C): Acceptable: “Good” primary and secondary sources of repayment. Loans to borrowers of average financial strength, stability and management expertise. Borrower should be a well-established individual or company with adequate financial resources to weather short-term fluctuations in the marketplace. Financial ratios and trends are favorable. The loans may be unsecured or supported by non-real estate collateral for which the value is more difficult to determine, reasonable credit risk and requiring an average amount of account officer attention. Unsecured credit is to be of unquestionable strength. Pass (D): Monitor: “Sufficient” primary source of repayment and acceptable secondary source of repayment. Acceptable business or individual credit, but the borrower’s operations, cash flow or financial conditions evidence moderate to average levels of risk. Loans are considered to be collectable in full, but may require a greater-than-average amount of loan officer attention. Borrowers are capable of absorbing normal setbacks without failure. Special Mention: A special mention asset has potential weaknesses that deserve close monitoring. These potential weaknesses may result in a deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. Special Mention should neither be a compromise between a pass grade and substandard, nor should it be a “catch all” grade to identify any loan that has a policy exception. Substandard: A substandard asset is inadequately protected by the current sound worth and payment capacity of the obligor or the collateral pledged. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Assets are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Formula Classified: Formula classified loans are all loans and credit cards delinquent 90 days and over which have yet to be formally classified Special Mention, Substandard or Doubtful by the Bank’s Loan Committee. In most instances, the monthly formula total is comprised primarily of residential real estate and consumer loans and credit cards. Commercial loans are typically formally classified by the Loan Committee no later than their 90-day delinquency, and thus usually do not become part of the formula classification. Real estate loans 90-days delinquent are in the foreclosure process and are typically completed within another 60 days, and thus are not formally classified during this period. Doubtful: A loan with weaknesses well enough defined that eventual repayment in full, on the basis of currently existing facts, conditions and values, is highly questionable, even though certain factors may be present which could improve the status of the loan. The probability of some loss is extremely high, but because of certain known factors, which may work to the advantage of strengthening of the assets (i.e. capital injection, perfecting liens on additional collateral, refinancing plans, etc.), its classification as an estimated loss is deferred until its more exact status can be determined. Loss: Loans classified as “Loss” are considered uncollectible, and are either unsecured or are supported by collateral that is of little to no value. As such, their continuance as recorded assets is not warranted. While this classification does not mandate that a loan has no ultimate recovery value, losses should be taken in the period these loans are deemed to be uncollectible. Loans identified as loss are immediately approved for charge off. The Bank may refer loans to outside collection agencies, attorneys, or its internal collection division to continue collection efforts. Any subsequent recoveries are credited to the Allowance for Loan Losses. Set forth below is a summary of the Company’s activity in the allowance for loan losses during the years ended: December 31, 2016 2015 2014 (Dollars in thousands) Balance, beginning of period $ 14,159 $ 12,526 $ 12,077 Provision for loan losses 3,900 4,488 4,540 Recoveries on loans previously charged off 3,007 1,402 1,779 Charged off loans (5,631 ) (4,257 ) (5,870 ) Balance, end of period $ 15,435 $ 14,159 $ 12,526 The provision for loan losses in the above summary reflects the net amount contributing to the allowance for loan losses, including the $6 thousand assigned to the reserve for off-balance sheet risk. Together, they comprise the $3.9 million provision reported in the Consolidated Statements of Income and the Consolidated Statements of Cash Flows. The increase in the allowance for loan losses is primarily due to the growth of the overall loan portfolio, partially offset by a reduction in classified loans and a decline in delinquency rates, along with management’s reassessment of economic conditions and prospects. The allowance will change in the future in response to changes in the size, composition and quality of the loan portfolio, as well as periodic reassessments of prospective economic conditions. Set forth below is information regarding gross loan balances and the related allowance for loan losses, by portfolio type, for the years ended December 31, 2016 and 2015.

Large groups of smaller-balance homogeneous loans are collectively evaluated for impairment. The Bank performs direct write-downs of impaired loans with a charge to the allocated component of the allowance, therefore reducing the allocated component of the reserve to zero at the end of each reporting period. The following table provides a summary of the delinquency status of the Bank’s gross loans by portfolio type: 30-59 Days Past Due 60-89 Days Past Due 90 Days and Greater Total Past Due Current Total Loans Outstanding (Dollars in thousands) December 31, 2016 Commercial Commercial & industrial $ 610 $ 269 $ 119 $ 998 $ 247,061 $ 248,059 Commercial mortgage - 770 691 1,461 550,811 552,272 Commercial construction - - - - 6,421 6,421 Commercial agriculture - - - - 747 747 Total commercial 610 1,039 810 2,459 805,040 807,499 Consumer Residential mortgage 6,277 3,457 3,211 12,945 131,006 143,951 Home equity - 102 - 102 378 480 Automobile 1,288 239 104 1,631 29,167 30,798 Other consumer 1 2,521 1,149 1,771 5,441 187,838 193,279 Total consumer 10,086 4,947 5,086 20,119 348,389 368,508 Total $ 10,696 $ 5,986 $ 5,896 $ 22,578 $ 1,153,429 $ 1,176,007 December 31, 2015 Commercial Commercial & industrial $ 787 $ 136 $ 25 $ 948 $ 232,403 $ 233,351 Commercial mortgage 2,222 - 3,656 5,878 414,171 420,049 Commercial construction - - - - 62,415 62,415 Commercial agriculture - - - - - - Total commercial 3,009 136 3,681 6,826 708,989 715,815 Consumer Residential mortgage 6,660 3,012 3,384 13,056 130,951 144,007 Home equity 7 - - 7 621 628 Automobile 736 179 59 974 25,567 26,541 Other consumer 1 2,488 1,590 1,481 5,559 178,038 183,597 Total consumer 9,891 4,781 4,924 19,596 335,177 354,773 Total $ 12,900 $ 4,917 $ 8,605 $ 26,422 $ 1,044,166 $ 1,070,588 1 Comprised of other revolving credit, installment, and overdrafts. The Bank’s outstanding loan balances have increased by $105.4 million over the past year and the delinquency rate of 1.9% at December 31, 2016, was 0.5% lower than the rate at December 31, 2015, as a result of of a gross decrease of $3.8 million in total past due loans. The decrease was primarily attributable to a $4.4 million decline in commercial mortgage delinquencies, partially offset by an increase of $657 thousand in automobile loans. Generally, the accrual of interest on a loan is discontinued when principal or interest payments become more than 90 days past due, unless management believes the loan is adequately collateralized and it is in the process of collection. When a loan is placed on non-accrual status, previously accrued but unpaid interest is reversed against current income. Subsequent collections of cash are applied as principal reductions when received, except when the ultimate collectability of principal is probable, in which case interest payments are credited to income. Non-accrual loans may be restored to accrual status when principal and interest become current and full repayment is expected. The following table provides information as of December 31, 2016 and 2015, with respect to loans on non-accrual status, by portfolio type: December 31, 2016 December 31, 2015 (Dollars in thousands) Non-accrual loans: Commercial Commercial & industrial $ 1,094 $ 1,334 Commercial mortgage 6,390 8,744 Commercial construction - - Commercial agriculture - - Total commercial 7,484 10,078 Consumer Residential mortgage 6,353 7,245 Home equity 35 37 Automobile - - Other consumer 1 174 123 Total consumer 6,562 7,405 Total non-accrual loans $ 14,046 $ 17,483 1 Comprised of other revolving credit, installment loans, and overdrafts.

The disaggregation of the portfolio by risk rating in the table reflects the following changes between December 31, 2015, and December 31, 2016: • Loans rated “pass” totaled $1.14 billion at December 31, 2016, an increase of $116.5 million from $1.02 billion at December 31, 2015, due primarily to the increases of $146.5 million in commercial mortgage loans, $10.5 million in commercial & industrial loans, $9.4 million in other consumer loans, $4.2 million in automobile loans, $1.3 million in residential mortgages and $747 thousand in commercial agricultural loans. The other consumer loans increase is due to new bookings and promotional programs, and the increase in automobile loans is the result of greater efforts in originating dealer loans. These increases were partially offset by the decreases of $56.0 million in commercial construction loans, concentrated in Guam. The decrease on commercial construction loans is due to the completion of the construction of the project, with the loan rolled over into a commercial mortgage. • The “special mention” category decreased by $6.9 million to $20.9 million at December 31, 2016. The commercial mortgage loan category decreased to $6.1 million, due to the upgrade of $5.5 million in two loan relationships from “special mention” to “pass” and a $876 thousand downgrade due to one loan relationship from “special mention” to “substandard.” In addition, there was a payoff of loans previously categorized as “special mention” totaling $10.7 million. Special mention commercial & industrial loans increased by $4.4 million, due primarily to the downgrade of a $14.0 million loan relationship from “pass.” • Loans classified as “substandard” decreased by $3.3 million, to $9.7 million at December 31, 2016 . Substandard commercial mortgage loans decreased by $3.1 million, to $7.5 million, primarily due to two large loan payoffs totaling $3.1 million. • The “formula classified” category decreased by $862 thousand during the period, to $8.1 million, primarily because of the decrease of $1.1 million in residential mortgages due to $545 thousand in loans being paid off, $504 thousand placed in OREO and $219 thousand in the process of foreclosure. These were partly offset by a $292 thousand increase in “formula classified” other consumer loans. Impaired Loans A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impaired loans include loans that are in non-accrual status and other loans that have been modified in Troubled Debt Restructurings (TDRs), where economic concessions have been granted to borrowers experiencing financial difficulties. These concessions typically result from the Company’s loss mitigation actions, and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions taken with the intention to maximize collections. The following table sets forth information regarding non-accrual loans and restructured loans, at December 31, 2016 and 2015: December 31, 2016 2015 (Dollars in thousands) Impaired loans: Restructured loans: Non-accruing restructured loans $ 6,589 $ 8,318 Accruing restructured loans 265 88 Total restructured loans 6,854 8,406 Other non-accruing impaired loans 7,457 9,165 Total impaired loans $ 14,311 $ 17,571 Impaired loans less than 90 days delinquent and included in total impaired loans $ 10,206 $ 10,597 The table below contains additional information with respect to impaired loans, by portfolio type, for the years ended December 31, 2016 and 2015: Recorded Investment Unpaid Principal Balance Average Recorded Investment Interest Income Recognized (Dollars in thousands) December 31, 2016, With no related allowance recorded: Commercial & industrial $ 1,359 $ 2,993 $ 1,497 $ - Commercial mortgage 6,390 6,629 7,710 - Commercial construction - - - - Commercial agriculture - - - - Residential mortgage 6,353 6,375 6,896 2 Home equity 35 35 36 - Automobile - - - - Other consumer 174 175 142 - Total impaired loans with no related allowance $ 14,311 $ 16,207 $ 16,281 $ 2 December 31, 2016, With an allowance recorded: Commercial & industrial $ - $ - $ - $ - Commercial mortgage - - - - Commercial construction - - - - Commercial agriculture - - - - Residential mortgage - - - - Home equity - - - - Automobile - - - - Other consumer - - - - Total impaired loans with no related allowance $ - $ - $ - $ - December 31, 2015, With no related allowance recorded: Commercial & industrial $ 1,402 $ 3,029 $ 1,526 $ - Commercial mortgage 8,744 10,508 8,810 - Commercial construction - - - - Commercial agriculture - - - - Residential mortgage 7,266 7,283 7,389 - Home equity 37 - 42 - Automobile - - - - Other consumer 122 123 119 - Total impaired loans with no related allowance $ 17,571 $ 20,943 $ 17,886 $ - December 31, 2015, With an allowance recorded: Commercial & industrial $ - $ - $ - $ - Commercial mortgage - - - - Commercial construction - - - - Commercial agriculture - - - - Residential mortgage - - - - Home equity - - - - Automobile - - - - Other consumer - - - - Total impaired loans with no related allowance $ - $ - $ - $ - Impairment is measured on a loan-by-loan basis for commercial and real estate loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral-dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. The Bank performs direct write-downs of impaired loans with a charge to the allocated component of the allowance, thereby reducing the allocated component of the reserve to zero at the end of each reporting period. Troubled Debt Restructurings The Bank had $6.9 million of troubled debt restructurings (TDRs) as of December 31, 2016. The restructured loans recorded with the Bank represent financing receivables, modified for the purpose of alleviating temporary impairments to the borrower’s financial condition. The modifications that the Bank has extended to borrowers have come in the form of a change in the amortization terms, a reduction in the interest rate, interest only payments and, in limited cases, a concession to the outstanding loan balance. The workout plans between the borrower and Bank are designed to provide a bridge for the cash flow shortfalls in the near term. As the borrower works through the near term issues, in most cases, the original contractual terms will be reinstated. At December 31, 2015, the Bank carried $8.4 million of troubled debt restructurings. This decrease of $1.6 million, to $6.9 million at December 31, 2016, is due primarily to four loans being removed from the restructured classification during 2016.

Transactions with Board of Directors	Note 12 – Transactions with Board of Directors The Directors of the Company and the Bank, and certain of the businesses with which they are associated, conduct banking transactions with the Company in the ordinary course of business. All loans and commitments to lend included in such transactions are made in accordance with applicable laws and on substantially the same terms, including interest rates and collateral, as those prevailing at the same time for comparable transactions with persons of similar creditworthiness that were not affiliated with the Company, and did not present any undue risk of collectability. The following is a summary of loan transactions with the Board of Directors of the Company and certain of their associated businesses: Years Ended December 31, 2016 2015 (Dollars in thousands) Beginning balance $ 4,656 $ 3,875 Undisbursed commitments 2,610 - New loans granted 3,878 1,300 Principal repayments (2,312 ) (519 ) Ending balance of term loans $ 8,832 $ 4,656 Year-end balance of revolving accounts 2,679 1,838 Total term loans and revolving accounts $ 11,511 $ 6,494 In addition, the Bank leases certain facilities from two separate entities in which two of its directors have separate ownership interests.

Income Taxes	Note 13 – Income Taxes The Bank pays income taxes in Guam and the Commonwealth of the Northern Mariana Islands under a territorial “mirror” of the U.S. Internal Revenue Code, with payments made to the respective territorial governments instead of the U.S. Treasury; there is no equivalent of a state income tax in either of these jurisdictions. The Bank also pays taxes to the governments of the Republic of Palau, the Federated States of Micronesia, the Republic of the Marshall Islands and the State of California. The income tax provision includes the following components: For the Years 2016 2015 2014 Government of Guam tax expense (benefit): Current $ 4,686 $ 2,168 $ 2,767 Deferred (961 ) (866 ) (416 ) Foreign income taxes (including U.S. income taxes) 1,991 2,764 1,405 Total income tax expense $ 5,716 $ 4,066 $ 3,756 The reasons for the differences between the statutory federal income tax rate and the effective tax rates are summarized as follows: 2016 2015 2014 Statutory Guam income tax rate 34.00 % 34.00 % 34.00 % Permanent differences -4.54 % -7.52 % -6.80 % Other 0.20 % 0.00 % 1.00 % Total income tax expense 29.66 % 26.48 % 28.20 % The difference between effective income tax expense and income tax expense computed at the Guam statutory rate was due to nontaxable interest income earned on loans to the Government of Guam for each of the years ended December 31, 2016, 2015 and 2014.

This is primarily due to the operating losses in the CNMI region. We record as a “deferred tax asset” on our balance sheet an amount equal to the tax credit and tax loss carry-forwards and tax deductions (“tax benefits”) that we believe will be available to us to offset or reduce the amounts of our income taxes in future periods. Under applicable federal and state income tax laws and regulations, such tax benefits will expire if not used within specified periods of time. Accordingly, the ability to fully use our deferred tax asset depends on the amount of taxable income that we generate during those time periods. At least once each year, or more frequently, if warranted, we make estimates of future taxable income that we believe we are likely to generate during those future periods. If we conclude, on the basis of those estimates and the amount of the tax benefits available to us, that it is more likely than not that we will be able to fully utilize those tax benefits prior to their expiration, we recognize the deferred tax asset in full on our balance sheet. On the other hand, if we conclude on the basis of those estimates and the amount of the tax benefits available to us that it has become more likely than not that we will be unable to utilize those tax benefits in full prior to their expiration, then we would establish (or increase any existing) valuation allowance to reduce the deferred tax asset on our balance sheet to the amount which we believe we are more likely than not to be able to utilize. Such a reduction is implemented by recognizing a non-cash charge that would have the effect of increasing the provision, or reducing any credit, for income taxes that we would otherwise have recorded in our statements of operations. The determination of whether and the extent to which we will be able to utilize our deferred tax asset involves significant management judgments and assumptions that are subject to period-to-period changes as a result of changes in tax laws, changes in the market, or economic conditions that could affect our operating results or variances between our actual operating results and our projected operating results, as well as other factors. The Bank is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2010.

Postemployment Benefits [Abstract]
Employee Benefit Plans	Note 14 – Employee Benefit Plans Stock Purchase Plan The Bank’s 2011 Employee Stock Purchase Plan (the “2011 Plan”) was adopted by the Bank’s Board of Directors and approved by the Bank’s Stockholders on May 2, 2011. The 2011 Plan is open to all employees of the Company and the Bank who have met certain eligibility requirements. Under the 2011 Plan, as amended and restated as of July 1, 2012, eligible employees can purchase, through payroll deductions, shares of common stock at a discount. The right to purchase stocks is granted to eligible employees during a period of time that is established from time to time by the Board of Directors of the Company. Eligible employees cannot accrue the right to purchase more than $25 thousand worth of stock at the fair market value at the beginning of each offer period. Eligible employees also may not purchase more than one thousand five hundred (1,500) shares of stock in any one offer period. The shares are purchased at 85% of the fair market price of the stock on the enrollment date. The Bank recognized $28 thousand in compensation expense in 2016 and $29 thousand in 2015 related to the intrinsic value of such purchases. Employee Retirement Savings Plan The Bank has a 401(k) Plan whereby substantially all employees, with at least one year of continuous service, are eligible to participate in the Plan. Effective March 1, 2008, the Bank makes matching contributions equal to 100% of an employee’s deferrals, up to 1% of the employee’s compensation, plus 50% of the employee’s deferrals that exceed 1% but are less than 6% of the employee’s compensation. Previously, matching contributions vested to the employee over a five-year period of service. Effective March 1, 2008, matching contributions become 100% vested to the employee after two years of service. For the years ended December 31, 2016, 2015 and 2014, the expense attributable to the Plan was $543 thousand, $506 thousand and $489 thousand, respectively. Supplemental Executive Retirement Plan (“SERP”) In April 2011, the Bank established an unfunded Supplemental Executive Retirement Plan (the “SERP”) for its Executive Officers and Senior Vice Presidents. The SERP provides that, subject to meeting certain vesting requirements described below, they will become entitled to receive 12 equal successive monthly retirement payments totaling $50,000 per annum for Senior Vice Presidents, $100,000 for the Executive Vice Presidents, and $150,000 for the President and CEO for the 15 years immediately following the date of their retirement or other termination of their employment. Their monthly retirement payments are not tied to service with the Bank. The Company follows FASB ASC 715-30-35, which requires us to recognize in our balance sheet the funded status of any post-retirement plans that we maintain, and to recognize, in other comprehensive income, changes in funded status of any such plans in any year in which changes occur. The changes in the projected benefit obligation of other benefits under the Plan during 2016 and 2015, its funded status at December 31, 2016 and 2015, and the amounts recognized in the balance sheet at December 31, 2016 and 2015, were as follows: At December 31, 2016 2015 Change in benefit obligation: Benefit obligation at beginning of period $ 2,925 $ 2,097 Service cost 851 737 Interest cost 127 91 Participant contributions - - Plan amendments - - Combination/divestiture/curtailment/settlement/termination - - Actuarial loss/(gain) - - (Benefits paid) - - Benefit obligation at end of period $ 3,903 $ 2,925 Funded status: Amounts recognized in the Statement of Financial Condition Unfunded accrued SERP liability—current $ 3,903 $ 2,925 Unfunded accrued SERP liability—noncurrent - - Total unfunded accrued SERP liability $ 3,903 $ 2,925 Net amount recognized in accumulated other comprehensive income Prior service cost/(benefit) $ - $ - Net actuarial loss/(gain) - - Total net amount recognized in accumulated other comprehensive income - - Accumulated benefit obligation $ 3,903 $ 2,925 Components of net periodic SERP cost: Service cost $ 3,568 $ 2,717 Interest cost 335 208 Expected return on plan assets - - Amortization of prior service cost/(benefit) - - Amortization of net actuarial loss/(gain) - - Net periodic SERP cost $ 3,903 $ 2,925 Recognized in other comprehensive income: Prior service cost/(benefit) $ - $ - Net actuarial loss/(gain) - - Amortization of prior service cost/(benefit) - - Amortization of net actuarial loss/(gain) - - Total recognized year to date in other comprehensive income $ - $ - Assumptions as of December 31: Assumed discount rate 4.33 % 4.33 % Rate of compensation increase 0.00 % 0.00 % As of December 31, 2016, $521 thousand in benefits are expected to be paid in the next five years.

Earnings Per Share Pro Forma [Abstract]
Earnings Per Common Share	Note 15 – Earnings Per Common Share Basic earnings per share represent income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Bank relate solely to shares for which employees’ funds have been collected but not issued under the Employee Stock Purchase Plan for 2016, 2015 and 2014, and are determined using the treasury stock method. Earnings per common share have been computed based on reported net income and the following share data: Years Ended December 31, 2016 2015 2014 Net income $ 13,553 $ 11,290 $ 9,560 less preferred stock dividends (49 ) - - Net income available for common stockholders 13,504 11,290 9,560 Weighted average number of common shares outstanding 9,251 9,017 8,818 Effect of dilutive options - - - Weighted average number of common shares outstanding- used to calculate diluted earnings per common share 9,251 9,017 8,818 Income per common share: Basic $ 1.46 $ 1.25 $ 1.08 Diluted $ 1.46 $ 1.25 $ 1.08

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 16 – Commitments and Contingencies The Bank is a party to credit-related financial instruments with off-balance-sheet risk, in the normal course of business, to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and commercial letters of credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount reflected in the consolidated financial statements. The Bank’s exposure to credit loss, in the event of nonperformance by the other parties to financial instruments for loan commitments and letters of credit, is represented by the contractual amount of these instruments. The Bank follows the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. A summary of financial instruments with off-balance-sheet risk at December 31, 2016 and 2015 is as follows: December 31, 2016 2015 Commitments to extend credit $ 152,585 $ 153,412 Letters of credit: Standby letters of credit $ 52,396 $ 49,256 Commercial letters of credit 3,045 6,546 Total $ 55,441 $ 55,802 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. The commitments for certain lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if it is deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the customer. The Bank had recorded $18 thousand in reserve liabilities associated with these commitments at December 31, 2016. Commercial and standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party or the shipment of merchandise from a third party. Those letters of credit are primarily issued to support government and private borrowing arrangements. Essentially all letters of credit issued have expiration dates within one year. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank generally holds collateral supporting these commitments. The Bank considers its standby letters of credit to be guarantees. At December 31, 2016, the maximum undiscounted future payments that the Bank could be required to make was $55.4 million. All of these arrangements mature within one year. The Bank generally has recourse to recover from the customer any amounts paid under these guarantees. Most of the guarantees are fully collateralized; however, some are unsecured. The Bank had not recorded any liabilities associated with these guarantees at December 31, 2016. Mortgage loans serviced for others are not included in the accompanying consolidated statements of condition. The unpaid principal balances of mortgage loans serviced for others were $211.0 million and $213.2 million at December 31, 2016 and 2015, respectively. At December 31, 2016 and 2015, the Bank recorded mortgage servicing rights at their fair value of $1.5 million and $1.5 million, respectively. The Bank utilizes facilities, equipment and land under various operating leases with terms ranging from 1 to 99 years. Some of these leases include scheduled rent increases. The total amount of the rent is being debited to expense under the straight-line method over the lease terms. The Bank has recorded a deferred obligation of $874 thousand and $820 thousand as of December 31, 2016 and 2015, respectively, which has been included within other liabilities, to reflect the excess of rent expense over cash paid on the leases. At December 31, 2016, annual lease commitments under the above noncancelable operating leases were as follows: Years ending December 31, 2017 $ 1,889 2018 1,528 2019 1,337 2020 1,190 2021 and Thereafter 21,385 Total $ 27,329 The Bank leases certain facilities from two separate entities in which two of its directors have separate ownership interests. Lease payments made to these entities during the years ended December 31, 2016, 2015 and 2014 approximated $379 thousand, $370 thousand and $370 thousand, respectively. Additionally, the Bank leases office space to third parties, with original lease terms ranging from 3 to 5 years with option periods ranging up to 15 years. At December 31, 2016, minimum future rents to be received under noncancelable operating sublease agreements were $47 thousand, $25 thousand, $20 thousand and $13 thousand for the years ending December 31, 2017, 2018, 2019 and 2020, respectively. A summary of rental activities for years ended December 31, 2016, 2015 and 2014, is as follows: For the Years Ended December 31, 2016 2015 2014 Rent expense $ 2,673 $ 2,480 $ 2,472 Less: sublease rentals 291 274 273 Net rent expense $ 2,382 $ 2,206 $ 2,199 Legal Contingencies The Bank is involved in certain legal actions and claims that arise in the ordinary course of business. Management believes that, as a result of its legal defenses and insurance arrangements, none of these matters are expected to have a material adverse effect on the Bank’s financial position, results of operations or cash flows.

Minimum Regulatory Capital Requ

Minimum Regulatory Capital Requirements	12 Months Ended

Banking And Thrift [Abstract]
Minimum Regulatory Capital Requirements	Note 17 – Minimum Regulatory Capital Requirements The Bank is subject to various regulatory capital requirements administered by the United States federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Bank’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items, as calculated under regulatory accounting practices. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the following table) of total, Tier 1 capital and common equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier 1 capital (as defined) to average assets (as defined). As of December 31, 2016 and 2015, the Bank met all capital adequacy requirements to which it is subject. As of December 31, 2016, the most recent notification from the Federal Deposit Insurance Corporation categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, common equity Tier 1 risk-based and Tier 1 leverage ratios as set forth in the following tables. There are no conditions or events since the notification that management believes have changed the Bank’s category. The Bank’s actual capital amounts and ratios as of December 31, 2016 and 2015 are also presented in the table. Actual For Capital Adequacy Purposes To Be Well Capitalized Under Prompt Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio At December 31, 2016: Total capital (to Risk Weighted Assets) $ 144,827 12.610 % $ 99,023 8.625 % $ 114,809 10.000 % Tier 1 capital (to Risk Weighted Assets) $ 130,463 11.360 % $ 76,061 6.625 % $ 91,847 8.000 % Tier 1 capital (to Average Assets) $ 130,463 7.060 % $ 73,937 4.000 % $ 92,421 5.000 % Common Equity Tier 1 Capital (to Risk Weighted Assets) $ 125,463 10.930 % $ 58,839 5.125 % $ 74,626 6.500 % At December 31, 2015: Total capital (to Risk Weighted Assets) $ 128,119 12.452 % $ 82,315 8.000 % $ 102,893 10.000 % Tier 1 capital (to Risk Weighted Assets) $ 115,242 11.200 % $ 61,736 6.000 % $ 82,315 8.000 % Tier 1 capital (to Average Assets) $ 115,242 7.404 % $ 62,256 4.000 % $ 77,820 5.000 % Common Equity Tier 1 Capital (to Risk Weighted Assets) $ 115,242 11.200 % $ 46,302 4.500 % $ 66,881 6.500 % In early July 2013, the Federal Reserve Board and the FDIC issued final rules implementing the Basel III regulatory framework and related Dodd-Frank Wall Street Reform and Consumer Protection Act changes. The rules revise minimum capital requirements and adjust prompt corrective action thresholds. The final rules revise the regulatory capital elements, add a new common equity Tier 1 capital ratio, increase the minimum Tier 1 capital ratio requirement, and implement a new capital conservation buffer. The rules also permit certain banking organizations to retain, through a one-time election, the existing treatment for accumulated other comprehensive income. The final rules took effect for community banks on January 1, 2015, subject to a transition period for certain parts of the rules. Also effective January 1, 2015, a new Basel III capital adequacy standard was implemented. The new Common Equity Tier 1 Capital (to risk weighted assets) ratio was established to ensure that core common equity (excluding non-voting shares and preferred stock), a more narrow measure of capitalization, is sufficient to maintain the safety and soundness of financial institutions. The Bank also exceeds the well capitalized standard under this measure. Management believes the Company and the Bank will remain well-capitalized under the new rules. Since the formation of the Company in 2011, our assets have grown by 74.2% ($818.4 million), while our stockholders’ equity has grown by 49.1% ($43.5 million, including $32.7 million in retained earnings). The growth in assets has pressured our capital ratios, but those ratios remain well above the well capitalized standards. To provide sufficient capital resources to expand our holdings, the Board has approved the issuance of an additional $5.0 million in common stock, of which $2.9 million was issued in 2015, and an additional $10.0 million in preferred stock, of which $9.8 million was issued during 2016. Non-Cumulative Perpetual Preferred Stock Commencing September 15, 2016, the Company offered a private placement of securities for the issuance and sale of an aggregate of 10,000 shares of its new Series A Non-Cumulative Perpetual Preferred Stock. This offer carried a subscription price of $1,000.00 per share and a yield of 5.5% (the “Series A Preferred Stock”) to various accredited and a limited number of non-accredited investors for total proceeds of up to $10 million (the “Offering”). Each subscriber can purchase a minimum number of Series A Preferred Stock equivalent to at least $250,000 (250 shares). The Offering agreement contains customary warranties, representations and indemnification provisions, and expired on December 31, 2016. At December 31, 2016, 9,800 of these shares were issued and outstanding.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 19 – Fair Value Measurements The Bank uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with ASC Topic 820, “Fair Value Measurements and Disclosures”, Fair Value Hierarchy In accordance with this guidance, the Bank groups its financial assets and financial liabilities, generally measured at fair value, in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1: Valuation is based on quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market, as well as certain U.S. Treasury securities that are highly liquid and are actively traded in over-the-counter markets. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2: Valuation is based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. The valuation may be based on quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which determination of fair value requires significant management judgment or estimation. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Financial assets measured at fair value on a recurring basis as of December 31, 2016 and 2015, are as follows: Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total At December 31, 2016 U.S. treasury notes and bonds $ 72,378 $ - $ - $ 72,378 U.S. government agency and sponsored enterprise (GSE) debt securities - 52,053 - 52,053 U.S. government agency pool securities - 237,126 - 237,126 U.S. government agency or GSE - 58,323 - 58,323 Other assets: MSRs - - 1,527 1,527 Total fair value $ 72,378 $ 347,502 $ 1,527 $ 421,407 At December 31, 2015 U.S. treasury notes and bonds $ 106,022 $ - $ - $ 106,022 U.S. government agency and sponsored enterprise (GSE) debt securities - - - - U.S. government agency pool securities - 50,904 - 50,904 U.S. government agency or GSE - 70,609 - 70,609 Other assets: MSRs - - 1,462 1,462 Total fair value $ 106,022 $ 121,513 $ 1,462 $ 228,997 There were no liabilities measured at fair value on a recurring basis as of December 31, 2016 and 2015. During the periods ended December 31, 2016, 2015 and 2014, the changes in Level 3 assets (consisting solely of MSRs) measured at fair value on a recurring basis are as follows: Twelve Months Ended December 31, 2016 2015 2014 Beginning balance $ 1,462 $ 1,405 $ 1,354 Realized and unrealized net gains: Included in net income 64 21 21 Included in other comprehensive income - - - Purchases, issuance and settlements Purchases - - - Issuances 1 36 30 Settlements - - - Ending balance $ 1,527 $ 1,462 $ 1,405 The valuation technique used for Level 3 MSRs is their discounted cash flow. Inputs considered in determining Level 3 pricing include the anticipated prepayment rates, discount rates, and cost to service. Significant increases or decreases in any of those inputs in isolation would result in a significantly lower or higher fair value measurement. The following table presents quantitative information about the valuation technique and unobservable inputs applied to Level 3 fair value measurements for financial instruments measured at fair value on a recurring basis: Estimated Fair Value Valuation Technique Unobservable Inputs Range of Inputs December 31, 2016 Financial instrument: MSRs $ 1,527 Discounted Cash Flow Discount Rate 6.08% - 9.25% Weighted Average Prepayment Rate (Public Securities Association) 125% There were no transfers into or out of the Bank’s Level 3 financial instruments for the periods ended December 31, 2016, and December 31, 2015. The valuation techniques for assets measured at fair value on a recurring basis are as follows: Investment Securities When quoted prices are available in an active market, the Bank classifies the securities within Level 1 of the valuation hierarchy. Level 1 securities include highly liquid U.S. Government debt and equity securities. If quoted market prices are not available, the Bank estimates fair values using pricing models and discounted cash flows that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes, and credit spreads. Examples of such instruments, which would generally be classified within Level 2 of the valuation hierarchy, include GSE obligations, corporate bonds, and other securities. Mortgage-backed securities are included in Level 2 if observable inputs are available. In certain cases where there is limited activity or less transparency around inputs to the valuation, the Bank would classify those securities in Level 3. At December 31, 2016 and 2015, the Bank did not have any Level 3 securities. Mortgage Servicing Rights The fair value measurement of mortgage servicing rights is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques that incorporate assumptions that market participants would use in estimating the fair value of servicing rights. The most important of these assumptions is the interest rate used in discounting the future cash flows into their present value. Other assumptions might include estimates of prepayment speeds, costs to service, escrow account earnings, contractual servicing fee income, prepayment and late fees, among other considerations. The Bank’s mortgage servicing rights are considered a Level 3 measurement at December 31, 2016 and 2015. Assets Measured at Fair Value on a Nonrecurring Basis Under certain circumstances the Bank makes adjustments to fair value for assets and liabilities even though they are not measured at fair value on an ongoing basis. The following table presents the financial instruments carried on the consolidated statements of condition by caption and by level in the fair value hierarchy at December 31, 2016 and 2015, for which a nonrecurring change in fair value has been recorded: Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total December 31, 2016 Financial assets: Loans, net Impaired loans $ - $ - $ - $ - Other assets Other real estate owned $ - $ - $ 2,746 $ 2,746 December 31, 2015 Financial assets: Loans, net Impaired loans $ - $ - $ 5 $ 5 Other assets Other real estate owned $ - $ - $ 3,460 $ 3,460 During the year 2016, one loan was written down as being collateral deficient in the amount of $13 thousand from its carrying value of $131 thousand. The fair value of loans subject to write downs is estimated using the appraised value of the underlying collateral, discounted as necessary due to management’s estimates of changes in economic conditions, less the estimated costs of selling the assets. Additionally, the Bank may make fair value adjustments to nonfinancial assets and liabilities in certain circumstances (such as impairments) though such nonfinancial assets and liabilities are not measured at fair value on recurring basis. The Bank does not have nonfinancial assets or liabilities for which a nonrecurring fair value has been recorded during the periods ended December 31, 2016 and 2015. Fair Value of Other Financial Instruments The estimated fair values of the Bank’s other financial instruments, excluding those assets recorded at fair value on a recurring basis on the Bank’s consolidated statements of condition, are as follows: Estimated fair value Carrying Level 1 Level 2 Level 3 December 31, 2016 (Dollars in thousands) Financial assets: Cash and cash equivalents $ 176,651 $ 176,651 $ - $ - Restricted cash 400 400 - - Federal Home Loan Bank stock 1,855 - 1,855 - Investment securities held-to-maturity 96,167 - 97,063 - Loans 1,158,045 - - 1,149,937 Total $ 1,433,118 $ 177,051 $ 98,918 $ 1,149,937 Financial liabilities: Deposits 1,778,670 - - 1,767,345 Total $ 1,778,670 $ - $ - $ 1,767,345 December 31, 2015 (Dollars in thousands) Financial assets: Cash and cash equivalents $ 100,799 $ 100,799 $ - $ - Restricted cash 400 400 - - Federal Home Loan Bank stock 1,762 - 1,762 - Investment securities held-to-maturity 100,519 - 101,924 - Loans 1,054,250 - - 1,046,589 Total $ 1,257,730 $ 101,199 $ 103,686 $ 1,046,589 Financial liabilities: Deposits $ 1,422,671 $ - $ - $ 1,416,843 Total $ 1,422,671 $ - $ - $ 1,416,843 The following methods were used by the Company in estimating fair value for its financial instruments not previously disclosed: Cash, Cash Equivalents and Restricted Cash, including Interest Bearing Deposits in Banks The carrying amount of cash and short-term instruments approximates fair value based on the short-term nature of the assets. Fair values for interest-bearing deposits that reprice frequently are based upon carrying value. Fair values of other interest bearing deposits with longer terms are estimated using discounted cash flow analyses based on current rates for similar types of deposits. Loans For variable-rate loans that re-price frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values for other loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values for nonperforming loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable. Deposit Liabilities The fair values disclosed for demand deposits (for example, interest and non-interest checking, passbook savings and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies market interest rates currently on comparable instruments to a schedule of aggregated expected monthly maturities on time deposits. Short-Term Borrowings The carrying amounts of Federal Funds purchased and FHLB advances maturing within ninety days approximate their fair values. We had no outstanding short-term borrowings at December 31, 2015 or 2016. Long-Term Borrowings Fair value of FHLB advances maturing after ninety days is determined based on expected present value techniques based on current market rates for advances with similar terms and remaining maturities. We had no outstanding long-term borrowings at December 31, 2015 or 2016. Accrued Interest The carrying amount of accrued interest approximates fair value due to its short term nature.

Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in effect in the United States (“GAAP”), on a basis consistent with prior periods. Certain prior period amounts have been reclassified to conform to current year presentation. The consolidated financial statements include the accounts of BankGuam Holding Company, the Bank BGIIS, and the Bank’s wholly owned subsidiaries, BankGuam Properties, Inc. and BankGuam Insurance Underwriters, Ltd. All significant intercompany and inter-branch balances and transactions have been eliminated in consolidation. The Company evaluates other entities to determine whether they are variable interest entities (“VIEs”). A VIE is a company in which equity investors do not have the characteristics of a controlling financial interest or where the entity does not have enough equity at risk to finance its activities without additional subordinated financial support from other parties. A variable interest in a VIE can arise from contractual, ownership or other monetary interests in the entity, which change with fluctuations in the fair value of the entity’s net assets. The Company would consolidate a VIE if it is the primary beneficiary. A primary beneficiary is the entity which holds both the power to direct the activities that most significantly impact the VIE and a variable interest that potentially could be significant to the VIE. The Company does not consolidate any VIEs. Assets held by the Bank’s Trust and Wealth Management departments in a fiduciary capacity are not assets of the Bank, and, accordingly, are not included in the accompanying consolidated financial statements.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the periods presented. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, valuation of other real estate owned and the fair value of financial instruments.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash on hand and balances due from banks, Federal Funds sold, cash items in transit and interest bearing deposits with other banks. The Bank is required by the Federal Reserve System to maintain cash reserves against certain of its deposit accounts. At December 31, 2016 and 2015, the required combined reserves totaled approximately $35.9 million and $25.6 million, respectively.
Restricted Cash	Restricted Cash Interest-bearing deposits in banks that mature within one year are carried at cost. $150 thousand of these deposits are held jointly under the names of Bank of Guam and the Guam Insurance Commissioner, and serve as a bond for the Bank of Guam Trust Department, and $250 thousand of these deposits are held under the Bank of Guam and are pledged for the Banker’s Loan Processing (BLP) program.
Investment Securities	Investment Securities Certain debt securities that management has the positive intent and ability to hold to maturity are classified as “held-to-maturity,” and are recorded at amortized cost. Securities not classified as held-to-maturity, including equity securities with readily determinable fair value, are classified as “available-for-sale” and are recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. The Bank does not hold securities for trading purposes. Declines in the fair value of securities below their cost that are other than temporary are reflected in earnings as realized losses. In determining other-than-temporary losses, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment, and is based on the information available to management at the time such a determination is made.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock The Bank is required to hold non-marketable equity securities, comprised of Federal Home Loan Bank of Des Moines (“FHLB”) stock, as a condition of membership. These securities are accounted for at cost, which equals par or redemption value. Ownership is restricted and there is no market for these securities. These securities are redeemable at par by the issuing government supported institutions. The primary factor supporting the carrying value is the commitment of the FHLB to perform its obligations, which includes providing credit and other services to the Bank.
Mortgage Servicing Rights (MSR)	Mortgage Servicing Rights (MSR) Mortgage servicing assets, included in other assets in the consolidated statements of financial condition, are recognized separately when rights are acquired through the sale of mortgage loans. Under the servicing assets and liabilities accounting guidance in ASC Topic 860, “ Transfers and Servicing
Loans Held for Investment	Loans Held for Investment Loans held for investment generally are reported at their outstanding unpaid principal balances, adjusted for charge-offs, an allowance for loan losses, and any deferred fees or costs on originated loans, as well as unamortized premiums or discounts on purchased loans, except for certain purchased loans that fall under the scope of Accounting Standards Codification (ASC) Topic 310-30, “ Accounting for Loans and Debt Securities Acquired with Deteriorated Credit Quality Interest income is accrued on the unpaid principal balance of loans. Loan origination fees, net of certain direct origination costs, are deferred and recognized as income using the effective interest method over the contractual life of the loans. The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Credit card loans and other unsecured consumer loans are typically charged off no later than 180 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on non-accrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on non-accrual or charged off are reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Loan Origination Fees and Costs	Loan Origination Fees and Costs All loan origination fees and related direct costs are deferred and amortized to interest income as an adjustment to yield over the respective lives of the loans using the effective interest method, except for loans that are revolving or short-term in nature for which the straight line method is used, which approximates the interest method.
Allowance for Loan Losses, Impaired Loans and Troubled Debt Restructurings	Allowance for Loan Losses, Impaired Loans and Troubled Debt Restructurings The allowance for loan losses is established as losses are estimated to be likely, and is funded through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectability of a loan is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is first determined by analyzing all classified loans (Substandard and Doubtful) in non-accrual for loss exposure and establishing specific reserves, as needed. ASC 310-10 defines loan impairment as the existence of uncertainty concerning collection of all principal and interest per the contractual terms of a loan. For collateral-dependent loans, impairment is typically measured by comparing the loan amount to the fair value of collateral, less costs to sell, with a specific reserve established for the “shortfall” amount. Other methods can be used in estimating impairment (market price or present value of expected future cash flows discounted at the loan’s original interest rate). The allowance for credit losses is management’s estimate of credit losses inherent in the loan portfolio at the balance sheet date. The Company has established a process to determine the appropriateness of the allowance for credit losses that assesses the losses inherent in the loan portfolio. The Company develops and documents its allowance methodology at the portfolio segment level – commercial loan portfolio and consumer loan portfolio. While portions of the allowance are attributable to the respective commercial and consumer portfolio segments, the entire allowance is available to absorb credit losses inherent in the total loan portfolio. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and real estate loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loans’ obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Bank does not separately identify individual consumer loans for impairment disclosures. In situations where, for economic or legal reasons related to a borrower’s financial difficulties, the Bank will grant a concession for other than an insignificant period of time to the borrower that would not otherwise be considered, the related loan is classified as a troubled debt restructuring (TDR). These modified terms may include rate reductions, principal forgiveness, term extensions, payment forbearance and other actions intended to minimize economic loss and to avoid foreclosure or repossession of the collateral, if applicable. For modifications where principal is forgiven, the entire amount of such principal forgiveness is immediately charged off. Loans classified as TDRs, including loans in trial payment periods (trial modifications), are considered impaired loans. Other than resolutions such as foreclosures, the Bank may remove loans held for investment from TDR classification, but only if they have been refinanced or restructured at market terms and qualify as a new loan.
Loans Held for Sale	Loans Held for Sale In its normal course of business, the Bank originates mortgage loans held for sale to the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”). The Bank has elected to measure its residential mortgage loans held for sale at the lower of cost or market. Origination fees and costs are recognized in earnings at the time of origination for newly originated loans held for sale, and the loans are sold to Freddie Mac at par. The Bank recognizes gains on the sale of loans sold to Freddie Mac only to the extent of MSRs retained in such sales. During the years ended December 31, 2016, 2015 and 2014, the Bank originated and sold approximately $18.6 million, $19.9 million and $22.8 million, respectively, of the above mentioned loans.
Off-Balance Sheet Financial Instruments	Off-Balance Sheet Financial Instruments In the ordinary course of business, the Bank has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit and standby letters of credit. Such financial instruments are recorded as off-balance sheet items when the commitment is made, then recorded as balance sheet items if and when funded (See Note 16).
Premises and Equipment	Premises and Equipment Premises and equipment are reported at cost, less accumulated depreciation and amortization. Depreciation and amortization are computed on the straight-line method over the estimated useful lives of the related assets. Depreciation expense has been computed principally using estimated lives of 15 to 40 years for premises and 5 to 10 years for furniture and equipment. Leasehold improvements are depreciated over the estimated lives of the assets or the expected terms of the leases, if shorter. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured. Construction-in-progress consists of accumulated direct and indirect costs associated with the Bank’s construction of premises and the purchase of equipment that has not yet been placed in service and, accordingly, has not yet been subjected to depreciation. Such assets begin depreciation over their estimated useful lives when completed and placed in service. Premises and equipment are periodically evaluated for impairment when events or changes in circumstances indicate the carrying amount may not be recoverable. Impairment exists when the expected undiscounted future cash flows of premises and equipment are less than their carrying amount. In that event, the Bank records a loss for the difference between the carrying amount and the estimated fair value of the asset based on quoted prices.
Other Real Estate Owned	Other Real Estate Owned Properties acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at the fair value of the property, reduced by estimated selling costs. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value, less the estimated cost to sell. Other real estate owned is estimated using the appraised value of the underlying collateral, discounted as necessary due to management’s estimates of changes in economic conditions, less estimated costs to sell. A valuation allowance is increased by provisions charged to earnings. Subsequent write-downs, income and expenses incurred in connection with holding such assets, and gains and losses realized from the sale of such assets, are charged to the valuation allowance.
Goodwill	Goodwill Goodwill is recorded in business combinations under the purchase method of accounting when the purchase price is greater than the fair value of net assets, including identifiable intangible assets. The Bank will assess goodwill for impairment at a reporting unit level on an annual basis or more frequently in certain circumstances. The Bank has the option of performing a qualitative assessment of goodwill, or to bypass the qualitative test and proceed directly to a quantitative test. If the Bank performs a qualitative assessment of goodwill to test for impairment and conclude it is more likely than not that a reporting unit’s fair value is greater than its carrying amount, quantitative tests are not required. However, if it is determined it is more likely than not that a reporting unit’s fair value is less than its carrying amount, then the Bank completes a quantitative assessment to determine if there is goodwill impairment. The Bank can apply various quantitative valuation methodologies, including discounted cash flow and earnings multiple approaches, to determine the estimated fair value, which is compared to the carrying value of each reporting unit. If the fair value is less than the carrying amount, an additional test is required to measure the amount of impairment. Based on the Bank’s more recent evaluation, no goodwill impairment was recorded.
Income Taxes	Income Taxes Income taxes represent taxes recognized under laws of the Government of Guam, which generally conform to U.S. income tax laws. Foreign income taxes result from payments of taxes with effective rates ranging from 2% to 5% of gross income in the FSM, the RMI and the ROP to their respective government jurisdictions. U.S. Federal, California and the Commonwealth of the Northern Mariana Islands income taxes are reflected as foreign taxes for financial reporting purposes. The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid for the period by applying the provisions of the enacted tax law to the taxable income. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term, “more likely than not,” means a likelihood of more than 50 percent; the terms, “examined,” and, “upon examination,” also include resolution of related appeals or litigation processes, if any. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. Uncertain tax positions that meet the more likely than not recognition threshold are measured to determine the amount of benefit to recognize. An uncertain tax position is measured at the largest amount of benefit that management believes has a greater than 50% likelihood of realization upon settlement. The Company recognizes interest and penalties on income taxes as a component of income tax expense.
Earnings Per Common Share	Earnings Per Common Share Basic earnings per share represent income available to common stockholders (after deducting dividends on preferred stock) divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may have been issued by the Company relate solely to outstanding stock options, and are determined using the treasury stock method.
Fair Value of Financial Instruments/Fair Value Option	Fair Value of Financial Instruments/Fair Value Option Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 19. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect these estimates. In addition, the fair value option provides an option to elect fair value as an alternative measurement for selected financial assets, financial liabilities, unrecognized firm commitments and written loan commitments not previously carried at fair value. The Company and the Bank have elected the fair value option for its mortgage servicing rights. The election was made to better reflect the underlying economics and to mitigate operational complexities in risk management activities.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when, (i) the assets have been isolated from the Bank – put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (ii) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) the Bank does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Contingencies	Contingencies From time to time, the Company may become involved in disputes, litigation and other legal actions. In such event, the Company estimates the range of liability related to pending litigation where the amount and range of loss can be estimated and information available prior to the issuance of financial statements indicates such loss is considered probable. Where a liability is probable and there is a range of estimated loss with no best estimate in the range, the Company records a charge equal to at least the minimum amount in the range.
Subsequent Events	Subsequent Events Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued (See Note 20). The Company recognizes in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing the financial statements. The Company’s financial statements do not recognize subsequent events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after the balance sheet date and before financial statements are available to be issued. The Company has evaluated events subsequent through the date that these consolidated financial statements are being filed with the Securities and Exchange Commission.
Recently Issued but Not Yet Adopted Accounting Pronouncements	Recently Issued but Not Yet Adopted Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326)” We are currently evaluating the impact of ASU 2016-13 on our consolidated financial statements, which is effective beginning January 1, 2020.
Fair Value Measurements	The Bank uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with ASC Topic 820, “Fair Value Measurements and Disclosures”, Fair Value Hierarchy In accordance with this guidance, the Bank groups its financial assets and financial liabilities, generally measured at fair value, in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1: Valuation is based on quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market, as well as certain U.S. Treasury securities that are highly liquid and are actively traded in over-the-counter markets. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2: Valuation is based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. The valuation may be based on quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which determination of fair value requires significant management judgment or estimation. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
