Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentationThe 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, 2019.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 September 30, 2020 and December 31, 2019 and the results of their operations for the three and nine months ended September 30, 2020 and 2019 and cash flows for the nine months ended September 30, 2020 and 2019. All such adjustments are of a normal recurring nature, unless otherwise disclosed below or in other referenced material. Results of operations for interim periods are not necessarily indicative of results for the full year. Recent accounting pronouncements. Credit losses . In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which replaces the incurred loss methodology with an expected loss methodology. The new methodology is referred to as the current expected credit loss (CECL) methodology and applies to financial assets subject to credit losses and measured at amortized cost and certain off-balance sheet credit exposures. This includes, but is not limited to loans, loan commitments and held-to-maturity securities. In addition, ASU No. 2016-13 amends the accounting for credit losses on available-for-sale (AFS) debt securities and purchased financial assets with credit deterioration. The other-than-temporary impairment model of accounting for credit losses on AFS debt securities has been 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 AFS debt security has been below the amortized cost will no longer impact the determination of whether a credit loss exists. The AFS debt security model requires the use of an allowance to record the estimated losses (and subsequent recoveries). The Company adopted ASU No. 2016-13 The CECL models use a probability-of-default, loss given default and exposure at default methodology to estimate the expected credit losses. Within each model or calculation, loans are further segregated based on additional risk characteristics specific to that loan type, such as risk rating, FICO score, bankruptcy score, age of loan and collateral. The Company uses both internal and external historical data, as appropriate, and a blend of economic forecasts to estimate credit losses over a reasonable and supportable forecast period and then reverts to a longer-term historical loss experience to arrive at lifetime expected credit losses. The reversion period incorporates forward-looking expectations about repayments (including prepayments) as determined by the Company’s asset liability management system. The allowance for credit losses (ACL) is a material estimate of the Company. As a result of the change from an incurred loss model to a methodology that considers the credit loss over the expected life of the loan, on January 1, 2020, the Company recorded an adjustment of $21 million to increase the ACL, including a $2 million increase in the allowance for loan commitments, with a corresponding adjustment to reduce retained earnings by $15 million on an after-tax basis . The ACL is based on the composition, characteristics and quality of the loans and off balance sheet credit exposures as well as the prevailing economic conditions as of the adoption date. The increase in the ACL primarily relates to required reserves for residential mortgages and consumer loans, due to the requirement to estimate lifetime expected credit losses, with lower ACL requirements for commercial and commercial real estate loans due to their short-term nature. Based on the credit quality of the Company’s existing held-to-maturity and AFS investment securities portfolio, the Company did not recognize an ACL at adoption for those investments. The adoption of the new standard did not have a material impact to the Utilities’ customer and other accounts receivables and accrued unbilled revenue. Results for reporting periods beginning after January 1, 2020 are presented under ASU No. 2016-13 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The table below summarizes the impact of the Company’s adoption of ASU No. 2016-13. January 1, 2020 (in thousands) Pre-ASU No. 2016-13 adoption Impact of ASU No. 2016-13 As reported under ASU No. 2016-13 HEI consolidated Loans held for investments, net 1 $ 5,067,821 $ (19,441) $ 5,048,380 Total assets $ 13,745,251 $ (19,441) $ 13,725,810 Deferred income taxes $ 379,324 $ (5,628) $ 373,696 Other 1 583,545 1,559 585,104 Total liabilities 11,430,698 (4,069) 11,426,629 Retained earnings 622,042 (15,372) 606,670 Total shareholders’ equity 2,280,260 (15,372) 2,264,888 Total liabilities and shareholders’ equity $ 13,745,251 $ (19,441) $ 13,725,810 1 The allowance for credit losses is classified in “Loans held for investments, net,” and the allowance for loan commitments is classified in “Other” liabilities in the Company’s condensed consolidated balance sheets. Reference Rate Reform . Reclassifications. Certain reclassifications of prior year amounts were made to conform to the current-year financial statement presentation. Reclassifications did not affect previously reported cash flows, net income or retained earnings.

Electric utility subsidiary [Abstract]
Electric utility segment	Electric utility segment Unconsolidated variable interest entities. Power purchase agreements . As of September 30, 2020, the Utilities had four PPAs for firm capacity (excluding the Puna Geothermal Ventures (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 are 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. Commitments and contingencies. 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. Power purchase agreements . Purchases from all IPPs were as follows: Three months ended September 30 Nine months ended September 30 (in millions) 2020 2019 2020 2019 Kalaeloa $ 39 $ 58 $ 111 $ 159 AES Hawaii 33 38 96 102 HPOWER 18 20 52 57 Hamakua Energy 12 17 36 51 Wind IPPs 30 30 83 73 Solar IPPs 17 11 45 26 Other IPPs 1 — 2 3 4 Total IPPs $ 149 $ 176 $ 426 $ 472 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 continue 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 November 20, 2020, 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 Department of Health of the State of Hawaii ( DOH) decision on AES Hawaii’s 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 9, 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. On May 10, 2019, the Hawaii Supreme Court issued a decision remanding the matter to the PUC for further proceedings consistent with the court’s decision which must include express consideration of Green House Gas (GHG) emissions that would result from approving the PPA, whether the cost of energy under the PPA is reasonable in light of the potential for GHG emissions, and whether the terms of the PPA are prudent and in the public interest, in light of its potential hidden and long-term consequences. On June 20, 2019, the PUC issued an order reopening the docket for further proceedings, including re-examining all of the issues in the proceedings. On September 29, 2019, the PUC issued an order setting the procedural schedule for the matter and on December 20, 2019, issued an order modifying the procedural schedule. Pre-hearing matters were completed on March 6, 2020. On July 9, 2020, the PUC issued an order denying the Hawaii Electric Light’s request to waive the amended and restated PPA from the PUC’s competitive bidding requirements and therefore, dismissed the request for approval of the amended and restated PPA without prejudice to possible participation in any future competitive bidding process. On July 20, 2020, Hu Honua filed a motion for reconsideration of the PUC’s order which was denied by the PUC on September 9, 2020. On September 16 2020, Hu Honua filed its notice of appeal to the Hawaii Supreme Court of the PUC’s order denying Hu Honua’s motion for reconsideration. Molokai New Energy Partners (MNEP). In July 2018, the PUC approved Maui Electric’s PPA with MNEP to purchase solar energy from a PV plus battery storage project. The 4.88 MW PV and 3 MW Battery Energy Storage System project was to deliver no more than 2.64 MW at any time to the Molokai system. On March 25, 2020, MNEP filed a complaint in the United Stated District Court for the District of Hawaii against Maui Electric claiming breach of contract. On June 3, 2020, Maui Electric provided Notice of Default and Termination of the PPA to MNEP terminating the PPA with an effective date of July 10, 2020. Thereafter, MNEP filed an amended Complaint to include claims relating to the termination and Hawaiian Electric filed its Answer to the Amended Complaint on September 11, 2020, disputing the facts presented by MNEP and all claims within the original and amended complaint. 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. The ERP/EAM Implementation Project went live in October 2018. Hawaii Electric Light and Hawaiian Electric began to incorporate their portion of the deferred project costs in rate base and started the amortization over a 12-year period in January 2020 and November 2020, respectively. As of September 30, 2020, the total deferred project costs and accrued carrying costs after the project went into service amounted to $59.5 million, which is net of the amortization of $0.5 million at Hawaii Electric Light. In February 2019, the PUC approved a methodology for passing the future cost saving benefits of the new ERP/EAM system to customers developed by the Utilities in collaboration with the Consumer Advocate. The Utilities filed a benefits clarification document on June 10, 2019, reflecting $150 million in future net O&M expense reductions and cost avoidance, and $96 million in capital cost reductions and tax savings over the 12-year service life. To the extent the reduction in O&M expense relates to amounts reflected in electric rates, the Utilities would reduce future rates for such amounts. In October 2019, the PUC approved the Utilities and the Consumer Advocate’s Stipulated Performance Metrics and Tracking Mechanism. As of September 30, 2020, the Utilities’ regulatory liability was $9.7 million for amounts to be returned to customers for reduction in O&M expense included in rates. As part of the settlement agreement approved in the Hawaiian Electric 2020 test year rate case, O&M benefits for Hawaiian Electric have been flowed through to customers as of October 2020. At the PUC’s direction, the Utilities have been filing Semi-Annual Enterprise System Benefits (SAESB) reports. The most recent SAESB report was filed on August 31, 2020 for the period January 1 through June 30, 2020. 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 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 DOH 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 September 30, 2020, representing the probable and reasonably estimable undiscounted cost for remediation of the Site and the Adjacent Parcel; however, final costs of remediation will depend on the 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 by the EPA to assess potential sources and extent of PCB contamination onshore at Waiau Power Plant. As of September 30, 2020, the reserve account balance recorded by Hawaiian Electric to address the PCB contamination was $4.6 million. The reserve balance represents the probable and reasonably estimable undiscounted cost for the onshore investigation and the remediation of PCB contamination in the offshore sediment. The final remediation costs will depend on the potential onshore source control requirements 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) rate adjustment mechanism (RAM) revenues for escalation in certain O&M expenses and rate base changes, (3) major project interim recovery (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. 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 may be reset upon the issuance of an interim or final decision and order (D&O) in a rate case. All Utilities were limited to the RAM Cap in 2020. 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. Projects eligible for recovery through the MPIR adjustment mechanism are major projects (i.e., projects with capital expenditures net of customer contributions in excess of $2.5 million), including, but not restricted to, renewable energy, energy efficiency, utility scale generation, grid modernization and smaller qualifying projects grouped into programs for review. The MPIR adjustment mechanism provides the opportunity to recover revenues for approved costs of eligible projects placed in service between general rate cases wherein cost recovery is limited by a revenue cap and is not provided by other effective recovery mechanisms. The request for PUC approval must include a business case, and all costs that are allowed to be recovered through the MPIR adjustment mechanism must be offset by any related benefits. The guidelines provide for accrual of revenues approved for recovery upon in-service date to be collected from customers through the annual RBA tariff. Capital projects that are not recovered through the MPIR would be included in the RAM and be subject to the RAM Cap, until the next rate case when the Utilities would request recovery in base rates. The 2019 approved MPIR amounts for Schofield Generating Station of $19.8 million (which accrued effective January 1, 2019), included the 2019 return on project amount (based on the 90% cap on cost recovery of the project through any mechanism other than base rates) in rate base, depreciation and incremental O&M expenses, are collected from June 2020 through May 2021. The PUC approved the Utilities’ requests for MPIR recovery of the cost of the Grid Modernization Strategy Phase 1 project and West Loch Photovoltaic (PV) project in March and December 2019, respectively. On June 5, 2020, the Utilities submitted 2020 MPIR amounts totaling $23.6 million for the Schofield Generation Station ($19.2 million), West Loch PV project ($3.8 million) and Grid Modernization Strategy Phase 1 project ($0.6 million for all three utilities) for the accrual of revenues effective January 1, 2020, that included the 2020 return on project amount (based on the capped amount) in rate base, depreciation and incremental O&M expenses, for collection from June 2021 through May 2022. On October 22, 2020, the PUC issued the final D&O in Hawaiian Electric’s 2020 test year rate case approving the parties’ settlement agreement, including the parties’ agreement to remove the 90% cap on cost recovery for the Schofield Generating Station, such that 100% of the allowed project costs will flow through the MPIR mechanism. The 2020 MPIR amounts will be revised to reflect the new lower depreciation rates effective January 1, 2020 as approved in the Hawaiian Electric 2020 test year rate case, and for the removal of the 90% cap on cost recovery and revised rate of return effective November 1, 2020. Performance incentive mechanisms . The PUC has established the following PIMs: (1) Service Quality performance incentives, (2) Phase 1 RFP PIM for procurement of low-cost renewable energy, (3) Phase 2 RFP PIMs for generation and generation plus storage project, and Grid Services and standalone storage. • Service Quality performance incentives (ongoing). 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 $6.8 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 reward is 8 basis points applied to the common equity share of each respective utility’s approved rate base (or maximum penalties or rewards of approximately $1.4 million - in total for the three utilities). • In December 2019, the Utilities accrued $0.3 million in estimated rewards for call center performance, net of service reliability penalties, for 2019. The net service quality performance rewards related to 2019 was reflected in the 2020 annual decoupling filing and increased customer rates in the period June 1, 2020 through May 31, 2021. • Phase 1 RFP PIM. Procurement of low-cost variable renewable resources through the request for proposal process in 2018 is 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. Half of the incentive was earned upon PUC approval of the PPAs and the other half is eligible to be earned in the year following the in-service date of the projects and is dependent on the amount of energy the Utilities receive from the facilities. The total amount of the incentive the Utilities are eligible for is capped at $3.5 million. Based on the seven PPAs approved in 2019, the Utilities recognized $1.7 million in 2019. • Phase 2 RFP PIMs. On October 9, 2019, the PUC issued an order establishing PIMs for the Utilities with regards to the Variable Renewable Dispatchable Generation and Energy Storage requests for proposals (RFPs) as well as the Delivery of Grid Services via Customer-sited Distributed Energy Resources RFPs that were issued on August 22, 2019 for Oahu, Maui and Hawaii island. The order establishes pricing thresholds, timelines to complete contracting, and other performance criteria for the performance incentive eligibility. The PIMs provide incentives only without penalties. The earliest the Utilities would be eligible for a PIM pursuant to this order is upon PUC approval of executed contracts resulting from the Phase 2 RFPs. The order requires contracts under the Grid Service RFP be filed for approval by May 2020 (subsequently extended to July 9, 2020), and by September 2020 under the Renewable RFPs, with a declining PIM for projects that are not filed by these deadlines. On July 9, 2020, the Utilities filed two Grid Service Purchase Agreements for the Grid Service RFP, which qualify for PIMs, however, details of the incentive metrics will be determined by PUC. On September 15, 2020, the Utilities filed eight power purchase agreements for the Phase 2 RFP. Of those eight, only one project qualified for a potential PIM incentive payout. The Utilities do not anticipate that any of the remaining projects from the Phase 2 RFP will qualify for PIM payouts. Annual decoupling filings . The net annual incremental amounts to be collected (refunded) from June 1, 2020 through May 31, 2021 are as follows: (in millions) Hawaiian Electric Hawaii Electric Light Maui Electric Total 2020 Annual incremental RAM adjusted revenues $ 20.6 $ 3.2 $ 5.7 $ 29.5 Annual change in accrued RBA balance as of December 31, 2019 (and associated revenue taxes) which incorporates MPIR recovery (46.5) (9.9) (11.0) (67.4) Incremental Performance Incentive Mechanisms (net) 2.2 (0.1) (0.1) 2.0 Net annual incremental amount to be collected (refunded) under the tariffs $ (23.7) $ (6.8) $ (5.4) $ (35.9) Performance-based regulation proceeding. On April 18, 2018, the PUC issued an order, instituting a proceeding to investigate performance-based regulation (PBR). 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. The proceeding has two phases. Phase 1 concluded in May 2019 with the issuance of a PUC order, which established guiding principles, regulatory goals, and priority outcomes to guide the development of the PBR mechanisms in Phase 2. The PUC identified the following guiding principles, which will inform the development of the PBR framework: 1) a customer-centric approach, 2) administrative efficiency to reduce regulatory burdens; and 3) utility financial integrity to maintain the utility’s financial health. Priority goals (and priority outcomes) identified by the PUC were: enhance customer experience (affordability, reliability, interconnection experience, and customer engagement), improve utility performance (cost control, distributed energy resources (DER) asset effectiveness, and grid investment efficiency), and advance societal outcomes (capital formation, customer equity, greenhouse gas reduction, electrification of transportation, and resilience). The order also outlined the PUC’s vision of a comprehensive PBR framework that would be further developed in Phase 2. The framework envisioned would include 1) a five-year multi-year rate plan with an index-driven annual revenue adjustment based on an inflation factor, an X-factor which would encompass productivity, a Z-factor to account for exceptional circumstances not in the utility’s control and a customer dividend, 2) a symmetric earnings sharing mechanism that would help ensure that utility earnings do not excessively benefit or suffer from external factors outside of utility control or unforeseen results of regulatory mechanisms, 3) off-ramp provisions, 4) continuation of the RBA, MPIR adjustment mechanism, the pension and OPEB tracking mechanism, and other recovery mechanisms, and 5) a portfolio of performance incentive mechanisms for customer engagement and DER asset effectiveness (rewards only), and interconnection experience (both rewards and penalties), in addition to scorecards to track progress against targeted performance levels, shared savings mechanisms to apportion savings to the utility and customers, and reported metrics. The Phase 2 schedule included working group meetings through the first half of 2020, followed by statements of positions that were filed in June 2020. In August 2020, the Parties filed their respective Phase 2 Reply Statement of Positions. In September 2020, the PUC held its hearing, and the Parties filed the post-hearing briefs in October 2020. The PUC’s decision is expected in December 2020. Most recent rate proceedings. Hawaiian Electric 2020 test year rate case . On May 27, 2020, Hawaiian Electric and the Consumer Advocate filed a Stipulated Settlement Letter, documenting a global settlement of all issues in this rate case. The Parties agreed that as a result of this settlement agreement, there will be no increase in electric revenues over the revenues established in the 2017 test year rate case. On May 13, 2020, the PUC issued its Final Report on the Management Audit, which recommended various operational and organizational changes intended to better manage costs and provide value to customers. The report also recommended a three-year timeframe to ramp up to a sustained $25 million in annual savings by the end of 2022, split between capital (approximately 80%) and O&M (approximately 20%). In its statement of position on the management audit filed on June 17, 2020, Hawaiian Electric committed to deliver these savings to customers over time through a proposal it later submitted in its statement of position in the PBR proceeding. On October 22, 2020, the PUC issued a final D&O approving the stipulated settlement agreement filed in the proceeding. As a result, there will be no increase in base electric rates established in the 2017 test year rate case. In the final D&O, the PUC approved the capital structure that consists of a 58% total equity ratio, and a ROACE of 9.5% for the 2020 test year. The resulting return on rate base (RORB) is 7.37%. The D&O approved the agreement to implement the overall lower depreciation rates approved in the last depreciation study proceeding, effective January 1, 2020. While the PUC generally approved the amount and treatment of Hawaiian Electric's Management Audit savings commitment reflected in the settlement agreement as reasonable, the PUC clarified that it is not bound in the Performance-Based Regulation proceeding to accept the proposed implementation details identified in the settlement agreement and retains full discretion in that proceeding as to the scope, nature, and treatment of Hawaiian Electric’s savings commitment. Hawaiian Electric is required to file revised tariff sheets within fifteen days of this final D&O. The effective date of the final tariffs is subject to PUC approval. Hawaii Electric Light 2019 test year rate case . On September 24, 2019, Hawaii Electric Light and the Consumer Advocate filed a Stipulated Partial Settlement Letter which documented agreements reached on all of the issues in the proceeding, except for the ROACE, capital structure, amortization period for the state investment tax credit, and automatic annual target heat rate adjustment. On November 13, 2019, the PUC issued an interim decision maintaining Hawaii Electric Light’s revenues at current effective rates based on an interim revenue requirement of $387 million, average rate base of $534 million, and a 7.52% RORB that incorporates a ROACE of 9.5% and 58.0% total equity ratio, and tariffs became effective January 1, 2020. On July 28, 2020, the PUC issued a final D&O, approving the Stipulated Partial Settlement Letter in part and ordering final rates for the 2019 test year to remain at current effective rates such that there is a zero increase in rates. The PUC determined that an appropriate ROACE for the 2019 test year is 9.5%, approved a capital structure of 58% total equity and approved as fair a 7.52% RORB. In addition, the order, among others, (1) approved a 10-year amortization period for the state investment tax credit; and (2) approved a modification to Hawaii Electric Light’s ECRC to incorporate a 98%/2% risk-sharing split between customers and Hawaii Electric Light with an annual maximum exposure cap of +/- $600,000. Hawaii Electric Light’s proposed final tariffs, PIM tariffs and ECRC tariff submitted on August 27, 2020 were approved by the PUC on October 26, 2020. The proposed final tariffs and PIM tariffs took effect on November 1, 2020, and the ECRC tariff will take effect on January 1, 2021. Regulatory assets for COVID-19 related expenses. On May 4, 2020, the PUC issued an order, authorizing all utilities, including the Utilities, to establish regulatory assets to record costs resulting from the suspension of disconnections of service during the pendency of the Governor’s Emergency Proclamation and until otherwise ordered by the PUC. In future proceedings, the PUC will consider the reasonableness of the costs, the appropriate period of recovery, any amount of carrying costs thereon, and any savings directly attributable to suspension of disconnects, and other related matters. As part of the order, the PUC prohibits the Utilities from charging late payment fees on past due payments. On June 30, 2020, the PUC issued an order approving the Utilities’ request made in April 2020 for deferral treatment of COVID-19 related expenses through December 31, 2020, and allowed the Utilities to file application to request an extension of the deferral period beyond December 31, 2020. The Utilities are required to file quarterly reports to update the Utilities’ financial condition, measures in place to assist their customers during the COVID-19 emergency situation, identifying the planned deferred costs and details for the deferred costs, and identifying funds received or benefits received that have resulted from the COVID-19 emergency period. The recovery of the regulatory assets would be determined in a subsequent proceeding. As of September 30, 2020, the Utilities recorded a total of $12.4 million in regulatory assets pursuant to the orders. Condensed consolidating financial information.

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’s investment securities portfolio did not require an allowance for credit losses at September 30, 2020. 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.

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 ASB 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. The allowance for credit losses on TDR loans that do not share risk characteristics are individually evaluated based on the present value of expected future cash flows discounted at the loan’s effective original contractual rate or based on the fair value of collateral less cost to sell. The financial impact of the estimated loss 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 credit losses. Loan modifications that occurred during the first nine months of 2020 and 2019 were as follows: Loans modified as a TDR Three months ended September 30, 2020 Nine months ended September 30, 2020 (dollars in thousands) Number Outstanding recorded investment (as of period end) 1 Related allowance (as of period end) Number Outstanding recorded investment (as of period end) 1 Related allowance (as of period end) Troubled debt restructurings Real estate: Residential 1-4 family — $ — $ — 1 $ 146 $ 7 Commercial real estate — — — 2 16,149 4,019 Home equity line of credit — — — 2 22 1 Residential land — — — 2 228 15 Commercial construction — — — — — — Residential construction — — — — — — Commercial 2 52 45 5 207 180 Consumer — — — — — — 2 $ 52 $ 45 12 $ 16,752 $ 4,222 Three months ended September 30, 2019 Nine months ended September 30, 2019 (dollars in thousands) Number Outstanding recorded investment (as of period end) 1 Related allowance (as of period end) Number Outstanding recorded investment (as of period end) 1 Related allowance (as of period end) Troubled debt restructurings Real estate: Residential 1-4 family 1 $ 324 $ — 10 $ 1,563 $ 165 Commercial real estate — — — — — — Home equity line of credit — — — 3 429 85 Residential land 1 350 — 3 1,169 — Commercial construction — — — — — — Residential construction — — — — — — Commercial 3 275 58 6 1,761 218 Consumer — — — — — — 5 $ 949 $ 58 22 $ 4,922 $ 468 1 T he 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. There were no loans modified in TDRs that experienced a payment default of 90 days or more during the third quarter and first nine months of 2020 and 2019. If a loan modified in a TDR subsequently defaults, 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 September 30, 2020 and December 31, 2019. The Coronavirus Aid, Relief, and Economic Security Act (CARES Act) provides that a financial institution may elect to suspend the requirements under GAAP for certain loan modifications that would otherwise be categorized as a TDR and any related impairment for accounting purposes. In response to the COVID-19 pandemic, the Board of Governors of the FRB, the FDIC, the National Credit Union Administration, the OCC, and the Consumer Financial Protection Bureau, in consultation with the state financial regulators (collectively, the “agencies”) issued a joint interagency statement (issued March 22, 2020; revised statement issued April 7, 2020). Some of the provisions applicable to the Company include, but are not limited to accounting for loan modifications, past due reporting and nonaccrual status and charge-offs. Loan modifications that do not meet the conditions of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. The agencies confirmed with the FASB staff that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or insignificant delays in payment. Financial institutions are not expected to designate loans with deferrals granted due to COVID-19 as past due because of the deferral. A loan’s payment date is governed by the due date stipulated in the legal agreement. If a financial institution agrees to a payment deferral, these loans would not be considered past due during the period of the deferral. Lastly, during short-term COVID-19 modifications, these loans generally should not be reported as nonaccrual or as classified. Collateral-dependent loans. A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the operation or sale of the collateral. Loans considered collateral-dependent were as follows: September 30, 2020 Amortized cost Collateral type (in thousands) Real estate: Residential 1-4 family $ 2,057 Residential real estate property Home equity line of credit 1,555 Residential real estate property Commercial construction — Total real estate 3,612 Commercial — Total $ 3,612 ASB had $3.0 million and $3.5 million of consumer mortgage loans collateralized by residential real estate property that were in the process of foreclosure at September 30, 2020 and December 31, 2019, respectively.

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) September 30, 2020 December 31, 2019 Unpaid principal balance $ 1,456,434 $ 1,276,437 Weighted average note rate 3.7

Debt Disclosure [Abstract]
Credit agreements and changes in debt	Credit agreements and changes in debt HEI and Hawaiian Electric each entered into a separate agreement with a syndicate of eight financial institutions (the HEI Facility and Hawaiian Electric Facility, respectively, and together, the Credit Facilities), effective July 3, 2017, to amend and restate their respective previously existing revolving unsecured credit agreements. The $150 million HEI Facility and $200 million Hawaiian Electric Facility both will terminate on June 30, 2022. None of the facilities are collateralized. As of September 30, 2020 and December 31, 2019, no amounts were outstanding under the Credit Facilities. The Credit Facilities will be maintained to support each company’s respective short-term commercial paper program, but may be drawn on to meet each company’s respective working capital needs and general corporate purposes. Changes in debt. On April 20, 2020, HEI closed on a $65 million 364-day term loan from a syndicate of two banks. The loan bears interest at a floating rate at HEI’s option of either (i) a rate equal to an alternate base rate as defined in the agreement or (ii) a rate equal to an adjusted London interbank offered rate, as defined in the agreement, plus an applicable margin, and matures on April 19, 2021. The proceeds of the loan were used to pay down the balance on the HEI Facility, which increased the available borrowing capacity on the HEI Facility by $65 million. The loan contains provisions requiring the maintenance by HEI of certain financial ratios substantially consistent with those in HEI’s existing, amended and restated revolving unsecured credit agreement. The loan may be prepaid without penalty at any time, but proceeds from any debt capital market transactions over $50 million must first be applied to pay down the term loan. On September 11, 2020, HEI entered into a $50 million note purchase agreement (HEI NPA) with The Prudential Insurance Company of America and several of its affiliates under which HEI has authorized the issue and sale of $50 million of unsecured senior notes (HEI Notes). Under the HEI NPA, HEI plans to draw $50 million on or before December 29, 2020. The HEI Notes bear interest at a fixed rate of 2.98%, require semi-annual interest payments, and mature December 15, 2030. The HEI Notes include substantially the same financial covenants and customary conditions as the HEI Facility. The proceeds from the HEI Notes will be used to refinance short-term borrowings and for general corporate purposes. The HEI Notes may be prepaid in whole or in part at any time at the prepayment price of the principal amount, together with interest accrued to the date of prepayment plus a “Make-Whole Amount,” as defined in the agreement. On September 28, 2020, Ka‘ie‘ie Waho Company, LLC (KWCL), a wholly owned indirect subsidiary of HEI, entered into a $13 million non-recourse term loan agreement with Bank of Hawaii. The proceeds of the loan were used to acquire a 6-MW solar photovoltaic facility on Kauai, which serves as collateral for the loan. The loan bears interest at a rate equal to LIBOR, as defined in the agreement, plus 2.00%, matures September 28, 2031, and requires the maintenance of a minimum debt service coverage ratio equal to at least 1.10 to 1.0. The loan requires quarterly principal and monthly interest payments, which total approximately $0.4 million per quarter. On April 20, 2020, Hawaiian Electric closed on a $75 million 364-day revolving credit agreement (364-day Revolver) with a syndicate of four banks. Under the 364-day Revolver, draws bear interest at a floating rate at Hawaiian Electric’s option of either (i) a rate equal to an alternate base rate as defined in the agreement or (ii) a rate equal to an adjusted London interbank offered rate, as defined in the agreement, plus an applicable margin, requires annual fees for undrawn amounts, and terminates on April 19, 2021. The 364-day Revolver includes substantially the same financial covenant and customary representations and warranties, affirmative and negative covenants, and events of default (the occurrence of which may result in the loan outstanding becoming immediately due and payable) consistent with those in Hawaiian Electric’s existing, amended and restated revolving unsecured credit agreement. As of September 30, 2020, Hawaiian Electric had no amounts outstanding on this revolving credit agreement. On May 14, 2020, the Utilities issued, through a private placement pursuant to separate note purchase agreements (NPAs), the following unsecured senior notes bearing taxable interest (May Notes): Series 2020A Series 2020B Series 2020C Aggregate principal amount $80 million $60 million $20 million Fixed coupon interest rate Hawaiian Electric 3.31% 3.31% 3.96% Hawaii Electric Light 3.96% Maui Electric 3.31% 3.96% Maturity date Hawaiian Electric 5/1/2030 5/1/2030 5/1/2050 Hawaii Electric Light 5/1/2050 Maui Electric 5/1/2030 5/1/2050 Principal amount by company: Hawaiian Electric $50 million (Green Bond) $40 million $20 million Hawaii Electric Light $10 million — — Maui Electric $20 million $20 million — The May Notes include substantially the same financial covenants and customary conditions as Hawaiian Electric’s credit agreement. Hawaiian Electric is also a party as guarantor under the NPAs entered into by Hawaii Electric Light and Maui Electric. All of the proceeds of the May Notes were used by Hawaiian Electric, Hawaii Electric Light and Maui Electric to finance their capital expenditures and/or to reimburse funds used for the payment of capital expenditures. The May Notes may be prepaid in whole or in part at any time at the prepayment price of the principal amount, together with interest accrued to the date of prepayment plus a “Make-Whole Amount,” as defined in the agreement. On May 19, 2020, Hawaiian Electric paid off and terminated the $100 million term loan credit agreement dated as of December 23, 2019. In addition, Hawaiian Electric entered into a 364-day, $50 million term loan credit agreement that matures on April 19, 2021. The term loan credit agreement includes substantially the same financial covenant and customary representations and warranties, affirmative and negative covenants, and events of default (the occurrence of which may result in the loan outstanding becoming immediately due and payable) consistent with those in Hawaiian Electric’s existing, amended and restated revolving unsecured credit agreement. The loan may be prepaid without penalty at any time, but proceeds from any debt capital market transactions over $75 million must be first applied to pay down the term loan. Hawaiian Electric drew the full $50 million on May 19, 2020. Changes in debt-subsequent event. On October 29, 2020, the Utilities executed, through a private placement pursuant to separate NPAs, unsecured senior notes bearing taxable interest (October Notes) as shown in the table below.

The Utilities have implemented pension and OPEB tracking mechanisms under which all of their retirement benefit expenses (except for executive life and nonqualified pension plan expenses) determined in accordance with GAAP are recovered over time. Under the tracking mechanisms, any actual costs determined in accordance with GAAP that are over/under amounts allowed in rates are charged/credited to a regulatory asset/liability. The regulatory asset/liability for each utility will then be amortized over 5 years beginning with the respective utility’s next rate case. Defined contribution plans information. For the first nine months of 2020 and 2019, the Company’s expenses for its defined contribution plans under the Hawaiian Electric Industries Retirement Savings Plan (HEIRSP) and the ASB 401(k) Plan were $5.5 million and $5.1 million, respectively, and cash contributions were $6.0 million and $6.0 million, respectively. For the first nine months of 2020 and 2019, the Utilities’ expenses for its defined contribution plan under the HEIRSP were $2.1 million and $1.9 million, respectively, and cash contributions were $2.1 million and $1.9 million, respectively.

Share-based Payment Arrangement [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 September 30, 2020, approximately 3.0 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 0.7 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. In June 2019, an additional 300,000 shares were made available for issuance under the 2011 Director Plan. As of September 30, 2020, there were 274,163 shares remaining available for future issuance under the 2011 Director Plan.

As of September 30, 2020, there was $6.2 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 2.7 years. Long-term incentive plan payable in stock. The 2018-2020, 2019-2021 and 2020-2022 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 earnings per share (EPS) growth, return on average common equity (ROACE), renewable portfolio standards, Hawaiian Electric’s net income growth, ASB’s efficiency ratio and Pacific Current’s EBITDA growth and return on average invested capital.

Income Tax Disclosure [Abstract]
Income taxes	Income taxes The Company’s and the Utilities’ effective tax rates (combined federal and state income tax rates) were 17% and 19%, respectively, for the nine months ended September 30, 2020. These rates differed from the combined statutory rates, due primarily to the Utilities’ amortization of excess deferred income taxes related to the provision in the Tax Act that lowered the federal income tax rate from 35% to 21%, the tax benefits derived from the low income housing tax credit investments and the non-taxability of the bank-owned life insurance income. The Company’s and the Utilities’ effective tax rates were 19% and 20%, respectively, for the nine months ended September 30, 2019. In August 2020, the Internal Revenue Service notified the Company that its 2017 and 2018 income tax returns will be examined. The Company was previously audited every year through 2011, at which time the IRS changed their internal policies regarding audit frequency. The Company has received several initial requests for general tax return information and has responded or is in the process of responding to such requests.

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 credit 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 . 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 its 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 . The fair value of fixed-maturity certificates of deposit was estimated by discounting the future cash flows using the rates currently offered for FHLB advances 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 fixed-rate long-term debt—other than bank 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. The carrying amount of floating rate long-term debt—other than bank approximated fair value because of the short-term interest reset periods. 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 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. For stock in Federal Home Loan Bank, the carrying amount is a reasonable estimate of fair value because it can only be redeemed at par.

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 September 30, 2020, the weighted average discount rate was 2.13%, 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 using (in thousands) Balance Level 1 Level 2 Level 3 September 30, 2020 Mortgage servicing rights $ 6,260 $ — $ — $ 6,260 December 31, 2019 Loans 25 — — 25 For the nine months ended September 30, 2020 and 2019, there were no adjustments to fair value for ASB’s loans held for sale.

Recent accounting pronouncements	Recent accounting pronouncements. Credit losses . In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which replaces the incurred loss methodology with an expected loss methodology. The new methodology is referred to as the current expected credit loss (CECL) methodology and applies to financial assets subject to credit losses and measured at amortized cost and certain off-balance sheet credit exposures. This includes, but is not limited to loans, loan commitments and held-to-maturity securities. In addition, ASU No. 2016-13 amends the accounting for credit losses on available-for-sale (AFS) debt securities and purchased financial assets with credit deterioration. The other-than-temporary impairment model of accounting for credit losses on AFS debt securities has been 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 AFS debt security has been below the amortized cost will no longer impact the determination of whether a credit loss exists. The AFS debt security model requires the use of an allowance to record the estimated losses (and subsequent recoveries). The Company adopted ASU No. 2016-13 The CECL models use a probability-of-default, loss given default and exposure at default methodology to estimate the expected credit losses. Within each model or calculation, loans are further segregated based on additional risk characteristics specific to that loan type, such as risk rating, FICO score, bankruptcy score, age of loan and collateral. The Company uses both internal and external historical data, as appropriate, and a blend of economic forecasts to estimate credit losses over a reasonable and supportable forecast period and then reverts to a longer-term historical loss experience to arrive at lifetime expected credit losses. The reversion period incorporates forward-looking expectations about repayments (including prepayments) as determined by the Company’s asset liability management system. The allowance for credit losses (ACL) is a material estimate of the Company. As a result of the change from an incurred loss model to a methodology that considers the credit loss over the expected life of the loan, on January 1, 2020, the Company recorded an adjustment of $21 million to increase the ACL, including a $2 million increase in the allowance for loan commitments, with a corresponding adjustment to reduce retained earnings by $15 million on an after-tax basis . The ACL is based on the composition, characteristics and quality of the loans and off balance sheet credit exposures as well as the prevailing economic conditions as of the adoption date. The increase in the ACL primarily relates to required reserves for residential mortgages and consumer loans, due to the requirement to estimate lifetime expected credit losses, with lower ACL requirements for commercial and commercial real estate loans due to their short-term nature. Based on the credit quality of the Company’s existing held-to-maturity and AFS investment securities portfolio, the Company did not recognize an ACL at adoption for those investments. The adoption of the new standard did not have a material impact to the Utilities’ customer and other accounts receivables and accrued unbilled revenue. Results for reporting periods beginning after January 1, 2020 are presented under ASU No. 2016-13 while prior period amounts continue to be reported in accordance with previously applicable GAAP.

Reference Rate Reform .
Troubled debt restructurings	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. The allowance for credit losses on TDR loans that do not share risk characteristics are individually evaluated based on the present value of expected future cash flows discounted at the loan’s effective original contractual rate or based on the fair value of collateral less cost to sell. The financial impact of the estimated loss 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 credit losses.
