Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) for interim financial information, the instructions to SEC Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In preparing the unaudited condensed consolidated financial statements, management is required 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 balance sheet and the reported amounts of revenues and expenses for the period. Actual results could differ significantly from those estimates. The accompanying unaudited condensed consolidated financial statements and the following notes should be read in conjunction with the audited consolidated financial statements and the notes thereto in HEI’s and Hawaiian Electric’s Form 10-K for the year ended December 31, 2018 . In the opinion of HEI’s and Hawaiian Electric’s management, the accompanying unaudited condensed consolidated financial statements contain all material adjustments required by GAAP to fairly state consolidated HEI’s and Hawaiian Electric’s financial positions as of March 31, 2019 and December 31, 2018 and the results of their operations and cash flows for the three months ended March 31, 2019 and 2018 Leases . In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-02, “Leases (Topic 842),” which requires that lessees recognize a liability to make lease payments (the lease liability) and a right-of-use (ROU) asset, representing its right to use the underlying asset for the lease term, for all leases (except short-term leases) at the commencement date. For finance leases, a lessee is required to recognize interest on the lease liability separately from amortization of the ROU asset in the consolidated statements of income. For operating leases, a lessee is required to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis. The Company adopted ASU No. 2016-02 on January 1, 2019 and used the effective date as the date of initial application. Consequently, financial information for dates and periods before January 1, 2019 will not be updated and the disclosures required under the new standard will not be provided (i.e., the Company will continue to report comparative periods presented in the financial statements in the period of adoption under Accounting Standards Codification (ASC) 840, including the required disclosures under ASC 840). The most significant effect of the new standard relates to the recognition of new ROU assets and lease liabilities on the Company’s balance sheet for purchase power agreements and real estate operating leases. On adoption, the Company recognized lease liabilities of approximately $257 million for the Company and approximately $236 million for the Utilities ( $215 million related to PPAs), based on the present value of the remaining minimum rental payments, with corresponding ROU assets, under current leasing standards for existing operating leases. In determining the lease liability upon transition, the Company used the incremental borrowing rates as of the adoption date based on the remaining lease term and remaining lease payments. See Note 6 for more information. Credit losses . In June 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ,” which is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations . ASU No. 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date (based on historical experience, current conditions and reasonable and supportable forecasts) and enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU No. 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The other-than-temporary impairment model of accounting for credit losses on available-for-sale debt securities will be replaced with an estimate of expected credit losses only when the fair value is below the amortized cost of the asset. The length of time the fair value of an available-for-sale debt security has been below the amortized cost will no longer impact the determination of whether a credit loss exists. The available-for-sale debt security model will also require the use of an allowance to record the estimated losses (and subsequent recoveries). The accounting for the initial recognition of the estimated expected credit losses for purchased financial assets with credit deterioration would be recognized through an allowance for credit losses with an offset to the cost basis of the related financial asset at acquisition (i.e., there is no impact to net income at initial recognition). The Company plans to adopt ASU No. 2016-13 in the first quarter of 2020. The guidance is to be applied on a modified retrospective basis with the cumulative effect of initially applying the amendments recognized in retained earnings at the date of initial application. The Company has assembled a project team that meets regularly to evaluate the provisions of this ASU, identify additional data requirements necessary and determine an approach for implementation. The team has assigned roles and responsibilities and developed key tasks to complete and a general timeline to be followed. The Company is evaluating the effect that this ASU will have on the consolidated financial statements and disclosures. Economic conditions and the composition of the Company’s loan portfolio at the time of adoption will influence the extent of the adopting accounting adjustment. Compensation-retirement benefits-defined benefit plans . In August 2018, the FASB issued ASU 2018-14, “Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans,” which makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. The new guidance eliminates requirements for certain disclosures that are no longer considered cost beneficial and requires new ones that the FASB considers pertinent. ASU No. 2018-14 is effective for fiscal years ending after December 15, 2020

Electric utility subsidiary [Abstract]
Electric utility segment	Electric utility segmentHECO Capital Trust III. Trust III, a statutory trust, which was formed to effect the issuance of $50 million of cumulative quarterly income preferred securities in 2004 (2004 Trust Preferred Securities), has at all times been a wholly-owned unconsolidated subsidiary of Hawaiian Electric. Trust III’s balance sheets as of March 31, 2019 and December 31, 2018 each consisted of $51.5 million of 2004 Debentures; $50 million of 2004 Trust Preferred Securities; and $1.5 million of trust common securities. Trust III’s income statements for the three months ended March 31, 2019 and 2018 consisted of $0.8 million of interest income received from the 2004 Debentures; $0.8 million of distributions to holders of the Trust Preferred Securities; and $25,000 of common dividends on the trust common securities to Hawaiian Electric. On April 12, 2019, Trust III issued a conditional notice of redemption to the holders of the Trust’s outstanding 6.50% Power purchase agreements . As of March 31, 2019 , the Utilities had four PPAs for firm capacity (excluding the PGV PPA as PGV has been offline since May 2018 due to lava flow on Hawaii Island) and other PPAs with independent power producers (IPPs) and Schedule Q providers (i.e., customers with cogeneration and/or power production facilities who buy power from or sell power to the Utilities), none of which is currently required to be consolidated as VIEs. Pursuant to the current accounting standards for VIEs, the Utilities are deemed to have a variable interest in Kalaeloa Partners, L.P. (Kalaeloa), AES Hawaii, Inc. (AES Hawaii) and Hamakua Energy by reason of the provisions of the PPA that the Utilities have with the three IPPs. However, management has concluded that the Utilities are not the primary beneficiary of Kalaeloa, AES Hawaii and Hamakua Energy because the Utilities do not have the power to direct the activities that most significantly impact the three IPPs’ economic performance nor the obligation to absorb their expected losses, if any, that could potentially be significant to the IPPs. Thus, the Utilities have not consolidated Kalaeloa, AES Hawaii and Hamakua Energy in its condensed consolidated financial statements. Hamakua Energy is an indirect subsidiary of Pacific Current and is consolidated in HEI’s condensed consolidated financial statements. For the other PPAs with IPPs, the Utilities have concluded that the consolidation of the IPPs was not required because either the Utilities do not have variable interests in the IPPs due to the absence of an obligation in the PPAs for the Utilities to absorb any variability of the IPPs, or the IPP was considered a “governmental organization,” and thus excluded from the scope of accounting standards for VIEs. Two IPPs of as-available energy declined to provide the information necessary for Utilities to determine the applicability of accounting standards for VIEs. If information is ultimately received from the IPPs, a possible outcome of future analyses of such information is the consolidation of one Fuel Contracts . The fuel contract entered into in January 2019, by the Utilities and PAR Hawaii Refining, LLC, for the Utilities' low sulfur fuel oil, high sulfur fuel oil, No. 2 diesel, and ultra-low sulfur diesel requirements was approved by the PUC, and became effective on April 28, 2019. The existing fuel contracts with Island Energy Services, LLC (IES), terminated on April 27, 2019, as agreed with IES under a mutual termination and release agreement entered into in November 2018. Contingencies . The Utilities are subject in the normal course of business to pending and threatened legal proceedings. Management does not anticipate that the aggregate ultimate liability arising out of these pending or threatened legal proceedings will be material to its financial position. However, the Utilities cannot rule out the possibility that such outcomes could have a material effect on the results of operations or liquidity for a particular reporting period in the future. Interim rate increases . As of March 31, 2019, the Utilities recognized $17 million of revenues with respect to the Maui Electric 2018 rate case interim order. On March 18, 2019, the PUC issued a final order which resulted in a refund of approximately $0.5 million proposed to be returned to customers, starting June 2019. Power purchase agreements . Purchases from all IPPs were as follows: Three months ended March 31 (in millions) 2019 2018 Kalaeloa $ 40 $ 40 AES Hawaii 32 37 HPOWER 18 15 Puna Geothermal Venture — 11 Hamakua Energy 16 7 Wind IPPs 20 22 Solar IPPs 7 6 Other IPPs 1 1 2 Total IPPs $ 134 $ 140 1 Includes hydro power and other PPAs Kalaeloa Partners, L.P. Under a 1988 PPA, as amended, Hawaiian Electric is committed to purchase 208 MW of firm capacity from Kalaeloa. Hawaiian Electric and Kalaeloa are currently in negotiations to address the PPA term that ended on May 23, 2016. The PPA automatically extends on a month-to-month basis as long as the parties are still negotiating in good faith. Hawaiian Electric and Kalaeloa have agreed that neither party will terminate the PPA (which has been subject to automatic extension on a month-to-month basis) prior to October 31, 2019, to allow for a negotiated resolution and PUC approval. AES Hawaii, Inc. Under a PPA entered into in March 1988, as amended (through Amendment No. 2) for a period of 30 years ending September 2022, Hawaiian Electric agreed to purchase 180 MW of firm capacity from AES Hawaii. Hawaiian Electric and AES Hawaii have been in dispute over an additional 9 MW of capacity. In February 2018, Hawaiian Electric reached agreement with AES Hawaii on an amendment to the PPA. However, in June 2018, the PUC issued an order suspending review of the amendment pending a DOH decision on AES’ request for approval of its Emission Reduction Plan and partnership with Hawaiian Electric. If approved by the PUC, the amendment will resolve AES Hawaii’s claims related to the additional capacity. Hu Honua Bioenergy, LLC (Hu Honua). In May 2012, Hawaii Electric Light signed a PPA, which the PUC approved in December 2013, with Hu Honua for 21.5 MW of renewable, dispatchable firm capacity fueled by locally grown biomass from a facility on the island of Hawaii. Under the terms of the PPA, the Hu Honua plant was scheduled to be in service in 2016. However, Hu Honua encountered construction and litigation delays, which resulted in an amended and restated PPA between Hawaii Electric Light and Hu Honua dated May 5, 2017. In July 2017, the PUC approved the amended and restated PPA, which becomes effective once the PUC’s order is final and non-appealable. In August 2017, the PUC’s approval was appealed by a third party. The appeal is still pending. Hu Honua expects to complete construction of the plant by the end of September 2019, and begin commissioning activities in the fourth quarter of 2019. Utility projects . Many public utility projects require PUC approval and various permits from other governmental agencies. Difficulties in obtaining, or the inability to obtain, the necessary approvals or permits can result in significantly increased project costs or even cancellation of projects. In the event a project does not proceed, or if it becomes probable the PUC will disallow cost recovery for all or part of a project, or if PUC-imposed caps on project costs are expected to be exceeded, project costs may need to be written off in amounts that could result in significant reductions in Hawaiian Electric’s consolidated net income. Enterprise Resource Planning/Enterprise Asset Management (ERP/EAM) implementation project. On August 11, 2016, the PUC approved the Utilities’ request to commence the ERP/EAM implementation project, subject to certain conditions, including a cap on cost recovery as well as a requirement that the Utilities achieve future cost savings consistent with a minimum of $244 million in ERP/EAM project-related benefits to be delivered to customers over the system’s 12 -year service life. The ERP/EAM Implementation Project went live in October 2018. In the Hawaiian Electric 2017 rate case, a settlement agreement approved by the PUC included authorization for the deferred project costs to accrue a return at 1.75% after the project went into service and until the deferred project costs are included in rate base, and for amortization of the deferred costs to not begin until the amortization expense is incorporated in rates and the unamortized deferred project costs are included in rate base. As of March 31, 2019 , the total deferred project costs and accrued carrying costs after the project went into service amounted to $58.7 million . In February 2019, the PUC approved a methodology for passing the benefits of the new ERP/EAM system to customers developed by the Utilities in collaboration with the Consumer Advocate. The minimum of $244 million in customer benefits to be delivered over the 12 -year service life is comprised of $141 million in future net O&M expense reductions and cost avoidance, and $103 million in future cost avoidance related to capital cost and tax cost. The Utilities are required to file their Benefits Clarification filing by June 3, 2019. West Loch PV Project. In June 2017, the PUC approved the expenditure of funds for Hawaiian Electric to build, own and operate a utility-owned, grid-tied 20 -MW (ac) solar facility on property owned by the Department of the Navy, including a proposed project cost cap of $67 million and a performance guarantee to provide energy at 9.56 cents /kWh or less to the system. In approving the project, the PUC agreed that the project is eligible for recovery of costs offset by related net benefits under the newly-established major project interim recovery (MPIR) adjustment mechanism. (See “Decoupling” section below for MPIR guidelines and cost recovery discussion.) Hawaiian Electric has provided supplemental materials, as requested by the PUC, to support meeting the MPIR guidelines, accompanied by system performance guarantee and cost savings sharing mechanisms. A decision on these matters is pending. Hawaiian Electric executed a fixed-price Engineering, Procurement, and Construction (EPC) contract for the project on December 6, 2017. The EPC contract includes the cost of the solar panels for the project, which is not subject to modification due to any tariffs that may be imposed under the current photovoltaic (PV) cell and module import tariffs. Construction of the facility began in the second quarter of 2018, and the facility is expected to be placed in service in the third quarter of 2019. Project costs incurred as of March 31, 2019 amounted to $44.2 million . Environmental regulation . The Utilities are subject to environmental laws and regulations that regulate the operation of existing facilities, the construction and operation of new facilities and the proper cleanup and disposal of hazardous waste and toxic substances. Hawaiian Electric, Hawaii Electric Light and Maui Electric, like other utilities, periodically encounter petroleum or other chemical releases associated with current or previous operations. The Utilities report and take action on these releases when and as required by applicable law and regulations. The Utilities believe the costs of responding to such releases identified to date will not have a material effect, individually or in the aggregate, on Hawaiian Electric’s consolidated results of operations, financial condition or liquidity. Former Molokai Electric Company generation site . In 1989, Maui Electric acquired by merger Molokai Electric Company. Molokai Electric Company had sold its former generation site (Site) in 1983, but continued to operate at the Site under a lease until 1985. The Environmental Protection Agency (EPA) has since identified environmental impacts in the subsurface soil at the Site. In cooperation with the Hawaii Department of Health and EPA, Maui Electric further investigated the Site and the Adjacent Parcel to determine the extent of impacts of polychlorinated biphenyls (PCBs), residual fuel oils and other subsurface contaminants. Maui Electric has a reserve balance of $2.7 million as of March 31, 2019 , representing the probable and reasonably estimable cost for remediation of the Site and the Adjacent Parcel; however, final costs of remediation will depend on cleanup approach implemented. Pearl Harbor sediment study . In July 2014, the U.S. Navy notified Hawaiian Electric of the Navy’s determination that Hawaiian Electric is a Potentially Responsible Party responsible for the costs of investigation and cleanup of PCB contamination in sediment in the area offshore of the Waiau Power Plant as part of the Pearl Harbor Superfund Site. Hawaiian Electric was also required to assess potential sources and extent of PCB contamination onshore at Waiau Power Plant. As of March 31, 2019 , the reserve account balance recorded by Hawaiian Electric to address the PCB contamination was $4.7 million . The reserve balance represents the probable and reasonably estimable cost for the onshore investigation and the remediation of PCB contamination in the offshore sediment. The final remediation costs will depend on the assessment of potential source control requirements for onshore sediment and actual offshore cleanup costs. Regulatory proceedings Decoupling . Decoupling is a regulatory model that is intended to provide the Utilities with financial stability and facilitate meeting the State of Hawaii’s goals to transition to a clean energy economy and achieve an aggressive renewable portfolio standard. The decoupling mechanism has the following major components: (1) monthly revenue balancing account (RBA) revenues or refunds for the difference between PUC-approved target revenues and recorded adjusted revenues, which delinks revenues from kilowatthour sales, (2) RAM revenues for escalation in certain O&M expenses and rate base changes, (3) MPIR component, (4) performance incentive mechanisms (PIMs), and (5) an earnings sharing mechanism, which would provide for a reduction of revenues between rate cases in the event the utility exceeds the return on average common equity (ROACE) allowed in its most recent rate case. Under the decoupling mechanism, triennial general rate cases are required. On March 29, 2019, the Utilities filed the 2019 annual filing which is subject to PUC review. Rate adjustment mechanism . The RAM is based on the lesser of: a) an inflationary adjustment for certain O&M expenses and return on investment for certain rate base changes, or b) cumulative annual compounded increase in Gross Domestic Product Price Index applied to annualized target revenues (the RAM Cap). Annualized target revenues reset upon the issuance of an interim or final decision and order (D&O) in a rate case. The RAM Cap impacted the Utilities' recovery of capital investments as follows: • Hawaiian Electric's RAM revenues were limited to the RAM Cap in 2018. • Maui Electric's RAM revenues were below the RAM Cap in 2018. • Hawaii Electric Light’s RAM revenues were limited to the RAM Cap in 2018. Major project interim recovery . On April 27, 2017, the PUC issued an order that provided guidelines for interim recovery of revenues to support major projects placed in service between general rate cases. The PUC approved recovery of capital costs under the MPIR for Schofield Generating Station, which increased revenues in 2018 by $3.6 million and will be collected in customer bills beginning in June 2019. In February 2019, Hawaiian Electric submitted an MPIR filing of $19.8 million for 2019 (which accrued effective January 1, 2019) that included the 2019 return on project amount (up to the capped amount) in rate base, depreciation and incremental O&M expenses, for collection from June 2020 through May 2021. Performance incentive mechanisms . The PUC has ordered the following PIMs. • Service Quality performance incentives are measured on a calendar-year basis. The PIM tariff requires the performance targets, deadbands and the amount of maximum financial incentives used to determine the PIM financial incentive levels for each of the PIMs to be re-determined upon issuance of an interim or final order in a general rate case for each utility. • Service Reliability Performance measured by System Average Interruption Duration and Frequency Indexes (penalties only). Target performance is based on each utility’s historical 10 -year average performance with a deadband of one standard deviation. The maximum penalty for each performance index is 20 basis points applied to the common equity share of each respective utility’s approved rate base (or maximum penalties of approximately $6.7 million - for both indices in total for the three utilities). • Call Center Performance measured by the percentage of calls answered within 30 seconds. Target performance is based on the annual average performance for each utility for the most recent 8 quarters with a deadband of 3% above and below the target. The maximum penalty or incentive is 8 basis points applied to the common equity share of each respective utility’s approved rate base (or maximum penalties or incentives of approximately $1.3 million - in total for the three utilities). • The Utilities accrued $2.1 million in estimated net service quality penalties for 2018, which will be reflected in the 2019 annual decoupling filing and will reduce customer rates in the period June 1, 2019 through May 31, 2020. • Procurement of low-cost variable renewable resources through the request for proposal process in 2018 measured by comparison of the procurement price to target prices. The incentive is a percentage of the savings determined by comparing procured price to a target of 11.5 cents per kilowatt-hour for renewable projects with storage capability and 9.5 cents per kilowatt-hour for energy-only renewable projects. For PPAs filed by December 31, 2018 and subsequently approved by the PUC, the incentive is 20% of the savings, with a cap of $3.5 million for the three utilities in total. For PPAs filed in January, February, and March 2019 and subsequently approved by the PUC, scaled incentives are 15% , 10% and 5% , respectively, of the savings for PPAs, with a cap of $ 3 million for the three utilities in total. There are no penalties. On March 25, 2019, the PUC approved six contracts, which were filed by December 31, 2018 and qualified for incentives. Half of the incentive is earned upon PUC approval of the contact and the other half is eligible to be earned in the year following the in-service date of the projects. The Utilities accrued $1.7 million in incentives in March 2019. Annual decoupling filings . The Utilities filed annual decoupling filings on March 29, 2019, which are subject to PUC review. The net annual incremental amounts proposed to be collected (refunded) from June 1, 2019 through May 31, 2020 are as follows: (in millions) Hawaiian Electric Hawaii Electric Light Maui Electric 2019 Annual incremental RAM adjusted revenues $ 14.0 $ 3.5 $ 3.3 Annual change in accrued RBA balance as of December 31, 2018 (and associated revenue taxes) $ (12.2 ) $ (1.9 ) $ 0.8 2017 Tax Act Adjustment * $ — $ — $ 2.8 Performance Incentive Mechanism $ 0.1 $ — $ (0.4 ) Net annual incremental amount to be collected under the tariffs $ 1.9 $ 1.6 $ 6.5 * Maui Electric incorporated a $2.8 million adjustment into its 2018 annual decoupling filing to incorporate the impact of the lower corporate income tax rate and the exclusion of the domestic production activities deduction, as a result of the 2017 Tax Cuts and Jobs Act (the Tax Act). This item is not recurring in 2019, therefore it is shown on this schedule of incremental changes as in increase. Performance-based regulation proceeding. On April 18, 2018, the PUC issued an order, instituting a proceeding to investigate performance-based regulation (PBR). The PUC intends to provide a forum to collaboratively develop modifications or new components to better align utility and customer interests. The PUC stated that PBR seeks to utilize both revenue adjustment mechanisms and performance mechanisms to more strongly align utilities’ incentives with customer interests. The order stated that, in general, the PUC is interested in ratemaking elements and/or mechanisms that result in: • Greater cost control and reduced rate volatility; • Efficient investment and allocation of resources regardless of classification as capital or operating expense; • Fair distribution of risks between utilities and customers; and • Fulfillment of State policy goals. Through this investigation, the PUC intends to: (1) identify specific areas of utility performance that should be improved; (2) determine appropriate metrics for measuring successful outcomes in those areas; and (3) establish reasonable financial rewards and/or penalties that are sufficient to incent the utility to achieve those outcomes. The proceeding has two phases. Phase 1 examines the current regulatory framework and identifies those areas of utility performance that are deserving of further focus in Phase 2. The PUC provided staff reports to the parties, held technical workshops and the parties filed briefs on: 1) goals and outcomes and 2) assessment of the existing regulatory framework and 3) metrics. PUC staff issued a Phase 1 proposal, and parties filed statements of position on March 8, 2019 and reply statements of position on April 5, 2019. A PUC decision on Phase 1 is pending. Phase 2 will address design and implementation of performance incentive mechanisms, revenue adjustment mechanisms and other regulatory reforms. Performance-based ratemaking legislation. On April 24, 2018, Act 005, Session Laws 2018 was signed into law, which establishes performance metrics that the PUC shall consider while establishing performance incentives and penalty mechanisms under a performance-based ratemaking model. The law requires that the PUC establish these performance-based ratemaking mechanisms on or before January 1, 2020. The PUC opened a proceeding on April 18, 2018. See “Performance-based regulation proceeding” above. Most recent rate proceedings. Hawaiian Electric consolidated 2014 and 2017 test year rate cases . On February 16, 2018, Hawaiian Electric implemented an interim increase of $36 million . On April 13, 2018, Hawaiian Electric implemented an additional interim rate adjustment to adjust rates for the impact of the Tax Act. On June 22, 2018, the PUC issued its Final D&O, approving final rate relief of a $37.7 million increase before the Tax Act impact reduction of $38.3 million , based on an ROACE of 9.5% and an overall rate of return of 7.57% . The PUC indicated that a revised ECRC mechanism shall reflect a 98% / 2% fossil fuel generation cost risk-sharing split between ratepayers and Hawaiian Electric, with an annual maximum increase or decrease to revenues of $2.5 million for the utility.

The D&O stated that a revised ECRC mechanism would replace the ECAC and effectuate the removal of the recovery of fuel and purchased power from base rates. It also stated that the ECRC shall reflect a 98% / 2% fossil fuel generation cost risk-sharing split between ratepayers and Maui Electric, with an annual maximum increase or decrease to revenues to $0.6 million for the utility. On April 17, 2019, Maui Electric filed proposed tariffs, with an effective date of June 1, 2019, and rate schedules reflecting a final increase of $12.2 million over revenues at current effective rates based on the approved 7.43% rate of return (which incorporates a ROACE of 9.5% and a capital structure that includes a 57% common equity capitalization) on a $454 million rate base. Upon the approval of the ECRC tariff, Maui Electric will file revised tariffs to rebalance rates resulting from the recovery of all fuel and purchased energy through the ECRC and the removal of the recovery of these costs from base rates.

Total gross unrealized losses were primarily attributable to change in market conditions. On a quarterly basis the investment securities are evaluated for changes in financial condition of the issuer. Based upon ASB’s evaluation, all securities held within the investment portfolio continue to be investment grade by one or more agencies. The contractual cash flows of the U.S. Treasury, federal agency obligations and agency mortgage-backed securities are backed by the full faith and credit guaranty of the United States government or an agency of the government. ASB does not intend to sell the securities before the recovery of its amortized cost basis and there have been no adverse changes in the timing of the contractual cash flows for the securities. ASB did not recognize OTTI for the quarters ended March 31, 2019 and 2018 . U.S. Treasury, federal agency obligations, corporate bonds, and mortgage revenue bonds have contractual terms to maturity. Mortgage-backed securities have contractual terms to maturity, but require periodic payments to reduce principal. In addition, expected maturities will differ from contractual maturities because borrowers have the right to prepay the underlying mortgages. The contractual maturities of investment securities were as follows: March 31, 2019 Amortized cost Fair value (in thousands) Available-for-sale Due in one year or less $ 15,000 $ 14,960 Due after one year through five years 133,142 133,294 Due after five years through ten years 55,997 55,595 Due after ten years 15,427 15,427 219,566 219,276 Mortgage-backed securities — issued or guaranteed by U.S. Government agencies or sponsored agencies 1,149,167 1,128,987 Total available-for-sale securities $ 1,368,733 $ 1,348,263 Held-to-maturity Mortgage-backed securities — issued or guaranteed by U.S. Government agencies or sponsored agencies $ 140,203 $ 142,333 Total held-to-maturity securities $ 140,203 $ 142,333 Proceeds from the sale of available-for-sale securities were nil for both the three months ended March 31, 2019 and 2018 .

For non-owner occupied residential properties, the loan-to-value ratio may not exceed 80% of the lower of the appraised value or purchase price at origination.

ASB performs an internal loan review and grading on an ongoing basis. The review provides management with periodic information as to the quality of the loan portfolio and effectiveness of its lending policies and procedures. The objectives of the loan review and grading procedures are to identify, in a timely manner, existing or emerging credit trends so that appropriate steps can be initiated to manage risk and avoid or minimize future losses. Loans subject to grading include commercial, commercial real estate and commercial construction loans. Each commercial and commercial real estate loan is assigned an Asset Quality Rating (AQR) reflecting the likelihood of repayment or orderly liquidation of that loan transaction pursuant to regulatory credit classifications: Pass, Special Mention, Substandard, Doubtful and Loss. The AQR is a function of the probability of default model rating, the loss given default and possible non-model factors which impact the ultimate collectability of the loan such as character of the business owner/guarantor, interim period performance, litigation, tax liens and major changes in business and economic conditions. Pass exposures generally are well protected by the current net worth and paying capacity of the obligor or by the value of the asset or underlying collateral. Special Mention loans have potential weaknesses that, if left uncorrected, could jeopardize the liquidation of the debt. Substandard loans have well-defined weaknesses that jeopardize the liquidation of the debt and are characterized by the distinct possibility that the Bank may sustain some loss. An asset classified Doubtful has the weaknesses of those classified Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. An asset classified Loss is considered uncollectible and has such little value that its continuance as a bankable asset is not warranted.

Troubled debt restructurings. A loan modification is deemed to be a TDR when the borrower is determined to be experiencing financial difficulties and ASB grants a concession it would not otherwise consider. All TDR loans are classified as impaired and are segregated and reviewed separately when assessing the adequacy of the allowance for loan losses based on the appropriate method of measuring impairment: (1) present value of expected future cash flows discounted at the loan’s effective original contractual rate, (2) fair value of collateral less cost to sell or (3) observable market price. The financial impact of the calculated impairment amount is an increase to the allowance associated with the modified loan. When available information confirms that specific loans or portions thereof are uncollectible (confirmed losses), these amounts are charged off against the allowance for loan losses. Loan modifications that occurred during the first quarters of 2019 and 2018 were as follows: Loans modified as a TDR Three months ended March 31, 2019 Three months ended March 31, 2018 (dollars in thousands) Number of contracts Outstanding recorded investment (as of period end) 1 Related allowance (as of period end) Number of contracts Outstanding recorded (as of period end) 1 Related allowance (as of period end) Troubled debt restructurings Real estate: Residential 1-4 family 8 $ 1,048 $ 5 1 $ 345 $ 107 Commercial real estate — — — — — — Home equity line of credit 2 264 23 18 2,155 417 Residential land 1 335 — — — — Commercial construction — — — — — — Residential construction — — — — — — Commercial 1 195 17 5 2,213 — Consumer — — — — — — 12 $ 1,842 $ 45 24 $ 4,713 $ 524 Loans modified in TDRs that experienced a payment default of 90 days or more during the first quarters of 2019 and 2018 , and for which the payment of default occurred within one year of the modification, were as follows: Three months ended March 31, 2019 Three months ended March 31, 2018 (dollars in thousands) Number of contracts Outstanding recorded (as of period end) 1 Number of contracts Outstanding recorded (as of period end) 1 TDRs that defaulted during the period within twelve months of their modification date Real estate: Residential 1-4 family — $ — 1 $ 49 Commercial real estate — — — — Home equity line of credit — — 1 86 Residential land — — — — Commercial construction — — — — Residential construction — — — — Commercial 1 19 — — Consumer — — — — 1 $ 19 2 $ 135 1 The period end balances reflect all paydowns and charge-offs since the modification period. TDRs fully paid off, charged-off, or foreclosed upon by period end are not included. If loans modified in a TDR subsequently default, ASB evaluates the loan for further impairment. Based on its evaluation, adjustments may be made in the allocation of the allowance or partial charge-offs may be taken to further write-down the carrying value of the loan. Commitments to lend additional funds to borrowers whose loan terms have been modified in a TDR totaled nil at March 31, 2019 and December 31, 2018 . The Company had $5.2 million and $4.2 million of consumer mortgage loans collateralized by residential real estate property that were in the process of foreclosure at March 31, 2019 and December 31, 2018 , respectively. Mortgage servicing rights (MSRs) . In its mortgage banking business, ASB sells residential mortgage loans to government-sponsored entities and other parties, who may issue securities backed by pools of such loans. ASB retains no beneficial interests in these loans other than the servicing rights of certain loans sold. ASB received proceeds from the sale of residential mortgages of $24.9 million and $33.1 million for the three months ended March 31, 2019 and 2018 , respectively, and recognized gains on such sales of $0.6 million for both of these periods. There were no repurchased mortgage loans for the three months ended March 31, 2019 and 2018 . The repurchase reserve was $0.1 million as of March 31, 2019 and 2018 . Mortgage servicing fees, a component of other income, net, were $0.7 million for both the three months ended March 31, 2019 and 2018 . Changes in the carrying value of MSRs were as follows: (in thousands) Gross Accumulated amortization Valuation allowance Net March 31, 2019 $ 18,786 $ (10,889 ) $ — $ 7,897 December 31, 2018 18,556 (10,494 ) — 8,062 Changes related to MSRs were as follows: Three months ended March 31 (in thousands) 2019 2018 Mortgage servicing rights Beginning balance $ 8,062 $ 8,639 Amount capitalized 230 335 Amortization (395 ) (433 ) Other-than-temporary impairment — — Carrying amount before valuation allowance 7,897 8,541 Valuation allowance for mortgage servicing rights Beginning balance — — Provision (recovery) — — Other-than-temporary impairment — — Ending balance — — Net carrying value of mortgage servicing rights $ 7,897 $ 8,541 ASB capitalizes MSRs acquired upon the sale of mortgage loans with servicing rights retained. On a monthly basis, ASB compares the net carrying value of the MSRs to its fair value to determine if there are any changes to the valuation allowance and/or other-than-temporary impairment for the MSRs. ASB uses a present value cash flow model to estimate the fair value of MSRs. Impairment is recognized through a valuation allowance for each stratum when the carrying amount exceeds fair value, with any associated provision recorded as a component of loan servicing fees included in “Revenues - bank” in the consolidated statements of income. A direct write-down is recorded when the recoverability of the valuation allowance is deemed to be unrecoverable. Key assumptions used in estimating the fair value of ASB’s MSRs used in the impairment analysis were as follows: (dollars in thousands) March 31, 2019 December 31, 2018 Unpaid principal balance $ 1,172,573 $ 1,188,514 Weighted average note rate 3.99 % 3.98 % Weighted average discount rate 10.0 % 10.0 % Weighted average prepayment speed 7.4 % 6.5 % The sensitivity analysis of fair value of MSRs to hypothetical adverse changes of 25 and 50 basis points in certain key assumptions was as follows: (dollars in thousands) March 31, 2019 December 31, 2018 Prepayment rate: 25 basis points adverse rate change $ (421 ) $ (250 ) 50 basis points adverse rate change (962 ) (566 ) Discount rate: 25 basis points adverse rate change (126 ) (139 ) 50 basis points adverse rate change (251 ) (275 ) The effect of a variation in certain assumptions on fair value is calculated without changing any other assumptions. This analysis typically cannot be extrapolated because the relationship of a change in one key assumption to the changes in the fair value of MSRs typically is not linear. Other borrowings. FHLB advances are fixed rate for a specific term. As of March 31, 2019, ASB had an FHLB advance outstanding for $25 million with a maturity date of April 2019. ASB was in compliance with all Advances, Pledge and Security Agreement requirements as of March 31, 2019. Securities sold under agreements to repurchase are accounted for as financing transactions and the obligations to repurchase these securities are recorded as liabilities in the condensed consolidated balance sheets. ASB pledges investment securities as collateral for securities sold under agreements to repurchase. All such agreements are subject to master netting arrangements, which provide for a conditional right of set-off in case of default by either party; however, ASB presents securities sold under agreements to repurchase on a gross basis in the balance sheet. The following tables present information about the securities sold under agreements to repurchase, including the related collateral received from or pledged to counterparties: (in millions) Gross amount of recognized liabilities Gross amount offset in the Balance Sheets Net amount of liabilities presented in the Balance Sheets Repurchase agreements March 31, 2019 $ 65 $ — $ 65 December 31, 2018 65 — 65 Gross amount not offset in the Balance Sheets (in millions) Net amount of liabilities presented in the Balance Sheets Financial instruments Cash collateral pledged Commercial account holders March 31, 2019 $ 65 $ 90 $ — December 31, 2018 65 92 — The securities underlying the agreements to repurchase are book-entry securities and were delivered by appropriate entry into the counterparties’ accounts or into segregated tri-party custodial accounts at the FHLB. The securities underlying the agreements to repurchase continue to be reflected in ASB’s asset accounts. Derivative financial instruments. ASB enters into interest rate lock commitments (IRLCs) with borrowers, and forward commitments to sell loans or to-be-announced mortgage-backed securities to investors to hedge against the inherent interest rate and pricing risks associated with selling loans. ASB enters into IRLCs for residential mortgage loans, which commit ASB to lend funds to a potential borrower at a specific interest rate and within a specified period of time. IRLCs that relate to the origination of mortgage loans that will be held for sale are considered derivative financial instruments under applicable accounting guidance. Outstanding IRLCs expose ASB to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan. The IRLCs are free-standing derivatives which are carried at fair value with changes recorded in mortgage banking income. ASB enters into forward commitments to hedge the interest rate risk for rate locked mortgage applications in process and closed mortgage loans held for sale. These commitments are primarily forward sales of to-be-announced mortgage backed securities. Generally, when mortgage loans are closed, the forward commitment is liquidated and replaced with a mandatory delivery forward sale of the mortgage to a secondary market investor. In some cases, a best-efforts forward sale agreement is utilized as the forward commitment. These commitments are free-standing derivatives which are carried at fair value with changes recorded in mortgage banking income. Changes in the fair value of IRLCs and forward commitments subsequent to inception are based on changes in the fair value of the underlying loan resulting from the fulfillment of the commitment and changes in the probability that the loan will fund within the terms of the commitment, which is affected primarily by changes in interest rates and the passage of time. The notional amount and fair value of ASB’s derivative financial instruments were as follows: March 31, 2019 December 31, 2018 (in thousands) Notional amount Fair value Notional amount Fair value Interest rate lock commitments $ 31,406 $ 462 $ 10,180 $ 91 Forward commitments 34,165 (161 ) 10,132 (43 ) ASB’s derivative financial instruments, their fair values and balance sheet location were as follows: Derivative Financial Instruments Not Designated as Hedging Instruments 1 March 31, 2019 December 31, 2018 (in thousands) Asset derivatives Liability derivatives Asset derivatives Liability Interest rate lock commitments $ 463 $ 1 $ 91 $ — Forward commitments 9 170 — 43 $ 472 $ 171 $ 91 $ 43 1 Asset derivatives are included in other assets and liability derivatives are included in other liabilities in the balance sheets.

Leases [Abstract]
Leases	Leases The Company adopted ASU No. 2016-02 and related amendments on January 1, 2019, and used the effective date as the date of initial application. The Company elected the practical expedient package under which the Company did not reassess its prior conclusions about whether any expired or existing contracts are or contain leases, whether there is a change in lease classification for any expired or existing leases under the new standard, or whether there were initial direct costs for any existing leases that would be treated differently under the new standard. The Company elected the short-term lease recognition exemption for all of its leases that qualify, and accordingly, does not recognize lease liabilities and ROU assets for all leases that have lease terms that are 12 months or less. The amounts related to short-term leases are not material. The Company elected the practical expedient to not separate lease and non-lease components for its real estate and equipment and fossil fuel and renewable energy PPAs . The Company elected the practical expedient to not assess all existing land easements that were not previously accounted for in accordance with ASC 840. The Company leases certain real estate and equipment for various terms under long-term operating lease agreements. The agreements expire at various dates through 2054 and provide for renewal options up to 10 years . The periods associated with the renewal options are excluded for the purpose of determining the lease term unless the exercise of the renewable option is reasonably certain. In the normal course of business, it is expected that many of these agreements will be replaced by similar agreements. Certain real estate leases require the Company to pay for operating expenses such as common area maintenance, real estate taxes and insurance. Additionally, the Utilities contract with independent power producers to supply energy under long-term power purchase agreements. Certain PPAs are treated as operating leases under the new standard because the Company elected the practical expedient package under which prior conclusions about lease identification were not reassessed. PPAs generally include variable lease payments (e.g., payments based on kWh), and several as-available PPAs have variable-only payment terms. For PPAs with no minimum lease payments, the Utilities do not recognize any lease liabilities or ROU assets, and the related costs are reported as variable lease costs. The Utilities’ lease payments for each operating lease agreement were discounted using its estimated unsecured borrowing rates for the appropriate term, reduced for the estimated impact of collateral. ASB’s lease payments for each operating lease agreement were discounted using Federal Home Loan Bank of Des Moines (FHLB) fixed rate advance rates, which are collateralized, for the appropriate term. The FHLB is the bank’s primary wholesale funding source and can provide borrowing rates for various terms starting at overnight borrowings to 30-year borrowing terms.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-based compensation	Share-based compensation Under the 2010 Equity and Incentive Plan, as amended, HEI can issue shares of common stock as incentive compensation to selected employees in the form of stock options, stock appreciation rights, restricted shares, restricted stock units, performance shares and other share-based and cash-based awards. The 2010 Equity and Incentive Plan (original EIP) was amended and restated effective March 1, 2014 (EIP) and an additional 1.5 million shares were added to the shares available for issuance under these programs. As of March 31, 2019 , approximately 3.2 million shares remained available for future issuance under the terms of the EIP, assuming recycling of shares withheld to satisfy minimum statutory tax liabilities relating to EIP awards, including an estimated 0.8 million shares that could be issued upon the vesting of outstanding restricted stock units and the achievement of performance goals for awards outstanding under long-term incentive plans (assuming that such performance goals are achieved at maximum levels). Under the 2011 Nonemployee Director Stock Plan (2011 Director Plan), HEI can issue shares of common stock as compensation to nonemployee directors of HEI, Hawaiian Electric and ASB. As of March 31, 2019 , there were 46,607 shares remaining available for future issuance under the 2011 Director Plan. Share-based compensation expense and the related income tax benefit were as follows: Three months ended March 31 (in millions) 2019 2018 HEI consolidated Share-based compensation expense 1 $ 2.2 $ 1.7 Income tax benefit 0.3 0.2 Hawaiian Electric consolidated Share-based compensation expense 1 0.8 0.6 Income tax benefit 0.1 0.1 1 For the three months ended March 31, 2019 and 2018, the Company has not capitalized any share-based compensation. Stock awards. HEI granted HEI common stock to nonemployee directors under the 2011 Director Plan as follows: Three months ended March 31 (dollars in thousands) 2019 2018 Shares granted — 1,074 Fair value $ — $ 39 Income tax benefit — 10 The number of shares issued to each nonemployee director of HEI, Hawaiian Electric and ASB is determined based on the closing price of HEI Common Stock on the grant date. Restricted stock units. Information about HEI’s grants of restricted stock units was as follows: Three months ended March 31 2019 2018 Shares (1) Shares (1) Outstanding, beginning of period 200,358 $ 33.05 197,047 $ 31.53 Granted 94,559 37.68 88,905 34.10 Vested (76,712 ) 32.61 (75,235 ) 30.55 Forfeited (6,980 ) 33.18 (2,629 ) 33.09 Outstanding, end of period 211,225 $ 35.28 208,088 $ 32.97 Total weighted-average grant-date fair value of shares granted (in millions) $ 3.6 $ 3.0 (1) Weighted-average grant-date fair value per share based on the average price of HEI common stock on the date of grant. For the first three months of 2019 and 2018 , total restricted stock units and related dividends that vested had a fair value of $3.2 million and $2.7 million , respectively, and the related tax benefits were $0.5 million and $0.5 million , respectively. As of March 31, 2019 , there was $6.9 million of total unrecognized compensation cost related to the nonvested restricted stock units. The cost is expected to be recognized over a weighted-average period of 3.1 years . Long-term incentive plan payable in stock. The 2017-2019, 2018-2020 and 2019-2021 long-term incentive plans (LTIP) provide for performance awards under the EIP of shares of HEI common stock based on the satisfaction of performance goals, including a market condition goal. The number of shares of HEI common stock that may be awarded is fixed on the date the grants are made, subject to the achievement of specified performance levels and calculated dividend equivalents. The potential payout varies from 0% to 200% of the number of target shares depending on the achievement of the goals. The market condition goal is based on HEI’s total shareholder return (TSR) compared to the Edison Electric Institute Index over the relevant three -year period. The other performance condition goals relate to EPS growth, return on average common equity (ROACE), Hawaiian Electric’s net income and ASB’s efficiency ratio. LTIP linked to TSR . Information about HEI’s LTIP grants linked to TSR was as follows: Three months ended March 31 2019 2018 Shares (1) Shares (1) Outstanding, beginning of period 65,578 $ 38.81 32,904 $ 39.51 Granted 34,647 41.07 35,626 38.21 Vested (issued or unissued and cancelled) — — — — Forfeited (1,914 ) 38.62 (1,739 ) 38.83 Outstanding, end of period 98,311 $ 39.61 66,791 $ 38.84 Total weighted-average grant-date fair value of shares granted (in millions) $ 1.4 $ 1.4 (1) Weighted-average grant-date fair value per share determined using a Monte Carlo simulation model. The grant date fair values of the shares were determined using a Monte Carlo simulation model utilizing actual information for the common shares of HEI and its peers for the period from the beginning of the performance period to the grant date and estimated future stock volatility and dividends of HEI and its peers over the remaining three -year performance period. The expected stock volatility assumptions for HEI and its peer group were based on the three -year historic stock volatility, and the annual dividend yield assumptions were based on dividend yields calculated on the basis of daily stock prices over the same three -year historical period. The following table summarizes the assumptions used to determine the fair value of the LTIP awards linked to TSR and the resulting fair value of LTIP awards granted: 2019 2018 Risk-free interest rate 2.48 % 2.29 % Expected life in years 3 3 Expected volatility 15.8 % 17.0 % Range of expected volatility for Peer Group 15.0% to 73.2% 15.1% to 26.2% Grant date fair value (per share) $41.07 $38.20 As of March 31, 2019 , there was $2.3 million of total unrecognized compensation cost related to the nonvested performance awards payable in shares linked to TSR. The cost is expected to be recognized over a weighted-average period of 1.8 years . LTIP awards linked to other performance conditions .

Fair Value Disclosures [Abstract]
Fair value measurements	Fair value measurements Fair value measurement and disclosure valuation methodology. The following are descriptions of the valuation methodologies used for assets and liabilities recorded at fair value and for estimating fair value for financial instruments not carried at fair value: Short-term borrowings—other than bank . The carrying amount of short-term borrowings approximated fair value because of the short maturity of these instruments. Investment securities . The fair value of ASB’s investment securities is determined quarterly through pricing obtained from independent third-party pricing services or from brokers not affiliated with the trade. Non-binding broker quotes are infrequent and generally occur for new securities that are settled close to the month-end pricing date. The third-party pricing vendors ASB uses for pricing its securities are reputable firms that provide pricing services on a global basis and have processes in place to ensure quality and control. The third-party pricing services use a variety of methods to determine the fair value of securities that fall under Level 2 of ASB’s fair value measurement hierarchy. Among the considerations are quoted prices for similar securities in an active market, yield spreads for similar trades, adjustments for liquidity, size, collateral characteristics, historic and generic prepayment speeds, and other observable market factors. To enhance the robustness of the pricing process, ASB will on a quarterly basis compare its standard third-party vendor’s price with that of another third-party vendor. If the prices are within an acceptable tolerance range, the price of the standard vendor will be accepted. If the variance is beyond the tolerance range, an evaluation will be conducted by ASB and a challenge to the price may be made. Fair value in such cases will be based on the value that best reflects the data and observable characteristics of the security. In all cases, the fair value used will have been independently determined by a third-party pricing vendor or non-affiliated broker. The fair value of the mortgage revenue bonds is estimated using a discounted cash flow model to calculate the present value of future principal and interest payments and, therefore is classified within Level 3 of the valuation hierarchy. Loans held for sale . Residential and commercial loans are carried at the lower of cost or market and are valued using market observable pricing inputs, which are derived from third party loan sales and, therefore, are classified within Level 2 of the valuation hierarchy. Loans held for investment . Fair value of loans held for investment is derived using a discounted cash flow approach which includes an evaluation of the underlying loan characteristics. The valuation model uses loan characteristics which includes product type, maturity dates and the underlying interest rate of the portfolio. This information is input into the valuation models along with various forecast valuation assumptions including prepayment forecasts, to determine the discount rate. These assumptions are derived from internal and third party sources. Since the valuation is derived from model-based techniques, ASB includes loans held for investment within Level 3 of the valuation hierarchy. Impaired loans . At the time a loan is considered impaired, it is valued at the lower of cost or fair value. Fair value is determined primarily by using an income, cost or market approach and is normally provided through appraisals. Impaired loans carried at fair value generally receive specific allocations within the allowance for loan losses. For collateral-dependent loans, fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Generally, impaired loans are evaluated quarterly for additional impairment and adjusted accordingly. Real estate acquired in settlement of loans . Foreclosed assets are carried at fair value (less estimated costs to sell) and are generally based upon appraisals or independent market prices that are periodically updated subsequent to classification as real estate owned. Such adjustments typically result in a Level 3 classification of the inputs for determining fair value. ASB estimates the fair value of collateral-dependent loans and real estate owned using the sales comparison approach. Mortgage servicing rights . Mortgage servicing rights (MSRs) are capitalized at fair value based on market data at the time of sale and accounted for in subsequent periods at the lower of amortized cost or fair value. MSRs are evaluated for impairment at each reporting date. ASB's MSRs are stratified based on predominant risk characteristics of the underlying loans including loan type and note rate. For each stratum, fair value is calculated by discounting expected net income streams using discount rates that reflect industry pricing for similar assets. Expected net income streams are estimated based on industry assumptions regarding prepayment expectations and income and expenses associated with servicing residential mortgage loans for others. Impairment is recognized through a valuation allowance for each stratum when the carrying amount exceeds fair value, with any associated provision recorded as a component of loan servicing fees included in "Revenues - bank" in the consolidated statements of income. A direct write-down is recorded when the recoverability of the valuation allowance is deemed to be unrecoverable. ASB compares the fair value of MSRs to an estimated value calculated by an independent third-party. The third-party relies on both published and unpublished sources of market related assumptions and their own experience and expertise to arrive at a value. ASB uses the third-party value only to assess the reasonableness of its own estimate. Deposit liabilities . Includes only fixed-maturity certificates of deposit beginning in 2018. The fair value of fixed-maturity certificates of deposit was estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining maturities. Deposit liabilities are classified in Level 2 of the valuation hierarchy. Other borrowings . For advances and repurchase agreements, fair value is estimated using quantitative discounted cash flow models that require the use of interest rate inputs that are currently offered for advances and repurchase agreements of similar remaining maturities. The majority of market inputs are actively quoted and can be validated through external sources, including broker market transactions and third party pricing services. Long-term debt—other than bank . Fair value of long-term debt of HEI and the Utilities was obtained from third-party financial services providers based on the current rates offered for debt of the same or similar remaining maturities and from discounting the future cash flows using the current rates offered for debt of the same or similar risks, terms, and remaining maturities. Long-term debt-other than bank is classified in Level 2 of the valuation hierarchy. Interest rate lock commitments (IRLCs) . The estimated fair value of commitments to originate residential mortgage loans for sale is based on quoted prices for similar loans in active markets. IRLCs are classified as Level 2 measurements. Forward sales commitments . To be announced (TBA) mortgage-backed securities forward commitments are classified as Level 1, and consist of publicly-traded debt securities for which identical fair values can be obtained through quoted market prices in active exchange markets. The fair values of ASB’s best efforts and mandatory delivery loan sale commitments are determined using quoted prices in the market place that are observable and are classified as Level 2 measurements. The following table presents the carrying or notional amount, fair value and placement in the fair value hierarchy of the Company’s financial instruments.

There were no transfers of financial assets and liabilities between Level 1 and Level 2 of the fair value hierarchy during the three months ended March 31, 2019 . The changes in Level 3 assets and liabilities measured at fair value on a recurring basis were as follows: Three months ended March 31 Mortgage revenue bonds 2019 2018 (in thousands) Beginning balance $ 23,636 $ 15,427 Principal payments received — — Purchases 4,334 — Unrealized gain (loss) included in other comprehensive income — — Ending balance $ 27,970 $ 15,427 ASB holds two mortgage revenue bonds issued by the Department of Budget and Finance of the State of Hawaii. The Company estimates the fair value by using a discounted cash flow model to calculate the present value of estimated future principal and interest payments. The unobservable input used in the fair value measurement is the weighted average discount rate. As of March 31, 2019 , the weighted average discount rate was 4.04% which was derived by incorporating a credit spread over the one month LIBOR rate. Significant increases (decreases) in the weighted average discount rate could result in a significantly lower (higher) fair value measurement. Fair value measurements on a nonrecurring basis. Certain assets and liabilities are measured at fair value on a nonrecurring basis and therefore are not included in the tables above. These measurements primarily result from assets carried at the lower of cost or fair value or from impairment of individual assets. The carrying value of assets measured at fair value on a nonrecurring basis were as follows: Fair value measurements (in thousands) Balance Level 1 Level 2 Level 3 March 31, 2019 Loans $ 237 $ — $ — $ 237 December 31, 2018 Loans 77 — — 77 Real estate acquired in settlement of loans 186 — — 186 For three months ended March 31, 2019 and 2018 , there were no adjustments to fair value for ASB’s loans held for sale.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recent accounting pronouncements	Leases . In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-02, “Leases (Topic 842),” which requires that lessees recognize a liability to make lease payments (the lease liability) and a right-of-use (ROU) asset, representing its right to use the underlying asset for the lease term, for all leases (except short-term leases) at the commencement date. For finance leases, a lessee is required to recognize interest on the lease liability separately from amortization of the ROU asset in the consolidated statements of income. For operating leases, a lessee is required to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis. The Company adopted ASU No. 2016-02 on January 1, 2019 and used the effective date as the date of initial application. Consequently, financial information for dates and periods before January 1, 2019 will not be updated and the disclosures required under the new standard will not be provided (i.e., the Company will continue to report comparative periods presented in the financial statements in the period of adoption under Accounting Standards Codification (ASC) 840, including the required disclosures under ASC 840). The most significant effect of the new standard relates to the recognition of new ROU assets and lease liabilities on the Company’s balance sheet for purchase power agreements and real estate operating leases. On adoption, the Company recognized lease liabilities of approximately $257 million for the Company and approximately $236 million for the Utilities ( $215 million related to PPAs), based on the present value of the remaining minimum rental payments, with corresponding ROU assets, under current leasing standards for existing operating leases. In determining the lease liability upon transition, the Company used the incremental borrowing rates as of the adoption date based on the remaining lease term and remaining lease payments. See Note 6 for more information. Credit losses . In June 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ,” which is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations . ASU No. 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date (based on historical experience, current conditions and reasonable and supportable forecasts) and enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU No. 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The other-than-temporary impairment model of accounting for credit losses on available-for-sale debt securities will be replaced with an estimate of expected credit losses only when the fair value is below the amortized cost of the asset. The length of time the fair value of an available-for-sale debt security has been below the amortized cost will no longer impact the determination of whether a credit loss exists. The available-for-sale debt security model will also require the use of an allowance to record the estimated losses (and subsequent recoveries). The accounting for the initial recognition of the estimated expected credit losses for purchased financial assets with credit deterioration would be recognized through an allowance for credit losses with an offset to the cost basis of the related financial asset at acquisition (i.e., there is no impact to net income at initial recognition). The Company plans to adopt ASU No. 2016-13 in the first quarter of 2020. The guidance is to be applied on a modified retrospective basis with the cumulative effect of initially applying the amendments recognized in retained earnings at the date of initial application. The Company has assembled a project team that meets regularly to evaluate the provisions of this ASU, identify additional data requirements necessary and determine an approach for implementation. The team has assigned roles and responsibilities and developed key tasks to complete and a general timeline to be followed. The Company is evaluating the effect that this ASU will have on the consolidated financial statements and disclosures. Economic conditions and the composition of the Company’s loan portfolio at the time of adoption will influence the extent of the adopting accounting adjustment. Compensation-retirement benefits-defined benefit plans . In August 2018, the FASB issued ASU 2018-14, “Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans,” which makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. The new guidance eliminates requirements for certain disclosures that are no longer considered cost beneficial and requires new ones that the FASB considers pertinent. ASU No. 2018-14 is effective for fiscal years ending after December 15, 2020
